I. Background
Title III of the Energy Policy and
Conservation Act of 1975 (42 U.S.C.
6291, et seq.; ‘‘EPCA’’) sets forth a
variety of provisions designed to
improve energy efficiency. (All
references to EPCA refer to the statute
as amended through the American
Energy Manufacturing Technical
Corrections Act (AEMTCA), Public Law
112–210 (Dec. 18, 2012)). Part B of title
III, which for editorial reasons was
redesignated as Part A upon
incorporation into the U.S. Code (42
U.S.C. 6291–6309, as codified),
establishes the ‘‘Energy Conservation
Program for Consumer Products Other
Than Automobiles.’’ These include
residential clothes washers, the subject
of today’s notice. (42 U.S.C. 6292(a)(7))
Under EPCA, the energy conservation
program consists essentially of four
parts: (1) Testing, (2) labeling, (3)
Federal energy conservation standards,

and (4) certification and enforcement
procedures. The testing requirements
consist of test procedures that
manufacturers of covered products must
use as the basis for (1) certifying to DOE
that their products comply with the
applicable energy conservation
standards adopted under EPCA, and (2)
making representations about the
efficiency of those products. Similarly,
DOE must use these test procedures to
determine whether the products comply
with any relevant standards
promulgated under EPCA.
General Test Procedure Rulemaking
Process
Under 42 U.S.C. 6293, EPCA sets forth
the criteria and procedures DOE must
follow when prescribing or amending
test procedures for covered products.
EPCA provides in relevant part that any
test procedures prescribed or amended
under this section shall be reasonably
designed to produce test results that
measure energy efficiency, energy use,
or estimated annual operating cost of a
covered product during a representative
average use cycle or period of use and
shall not be unduly burdensome to
conduct. (42 U.S.C. 6293(b)(3))
In addition, if DOE determines that a
test procedure amendment is warranted,
it must publish proposed test
procedures and afford the public an
opportunity to present oral and written
comments on them. (42 U.S.C.
6293(b)(2)) Finally, in any rulemaking to
amend a test procedure, DOE must
determine to what extent, if any, the
proposed test procedure would alter the
measured energy efficiency of any
covered product as determined under
the existing test procedure. (42 U.S.C.
6293(e))
DOE test procedures for clothes
washers are codified at appendices J1
and J2 to 10 CFR part 430 subpart B
(hereafter, ‘‘appendix J1’’ and
‘‘appendix J2’’). DOE most recently
amended the test procedures for clothes
washers on March 7, 2012 (hereafter, the
‘‘March 2012 final rule’’). 77 FR 13888.
The March 2012 final rule amended
certain provisions in appendix J1 and
also established the clothes washer test
procedure codified in appendix J2.
Manufacturers of residential clothes
washers are required to make
representations of energy efficiency
using either appendix J1 or appendix J2,
as revised by the March 2012 final rule.
Manufacturers must use a single test
procedure for all representations for a
basic model and may not use appendix
J1 for certain representations and
appendix J2 for other representations.
Compliance with DOE’s amended
standards for residential clothes

washers, and the corresponding
mandatory use of the test procedure at
appendix J2 for all representations, is
required as of March 7, 2015. 77 FR
32308 (May 31, 2012) and 77 FR 59719
(October 1, 2012).
II. Summary of the Notice of Proposed
Rulemaking
In this NOPR, DOE proposes
clarifications and technical amendments
to its test procedures for clothes washers
at appendix J1 and appendix J2. In
addition, DOE proposes amendments to
the reporting and verification
requirements for residential clothes
washers. DOE has determined that
today’s proposed amendments, as
described in section III, would not alter
the measured efficiency of clothes
washers. The proposed amendments
either codify guidance interpreting
DOE’s existing regulations, provide
further clarification of the relevant test
procedure provisions, provide improved
organization of each section, or correct
formatting errors in DOE’s clothes
washer test procedures.
III. Discussion
A. Clothes Container Capacity
Measurement
1. Capacity Measurement in Appendix
J1
Section 3.1 of appendix J1 contains
procedures for measuring the clothes
container capacity. The capacity
measurement procedure involves filling
the clothes container with water and
determining the volume based on the
weight of the added water divided by
the water density. Section 3.1.4
specifies that the clothes container be
filled manually with water to its
‘‘uppermost edge.’’
DOE published guidance on July 6,
2010, clarifying the definition of the
uppermost edge of the clothes container
for the purpose of performing the
capacity measurement. See DOE’s
guidance document at: https://
www1.eere.energy.gov/buildings/
appliance_standards/pdfs/
clotheswashers_faq1_2010-07-06.pdf.
The guidance document provides
detailed descriptions and illustrations of
the boundary defining the uppermost
edge of the clothes container for both
top-loading and front-loading clothes
washers. For top-loading vertical-axis
clothes washers, DOE’s guidance
document defines the uppermost edge
of the clothes container as the highest
point of the innermost diameter of the
tub cover. For front-loading horizontalaxis clothes washers, the guidance
document specifies filling the clothes
container with water to the highest
PO 00000
Frm 00003
Fmt 4701
Sfmt 4702
23063
point of contact between the door and
the door gasket. If any portion of the
door or the door gasket would occupy
the measured volume when the door is
closed, that volume must be excluded
from the measurement. DOE’s guidance
document also provides illustrations of
the boundary defining the uppermost
edge of the clothes container for both
top-loading and front-loading clothes
washers. The proposed amendments
incorporate these clarifications into
section 3.1.4 of appendix J1, including
the illustrations.
The proposal also further clarifies the
appropriate water fill levels for frontloading horizontal-axis clothes washers
with concave door shapes and toploading horizontal-axis clothes washers.
For front-loading horizontal-axis clothes
washers with concave door shapes, the
capacity measurement would include
any space above the plane defined by
the highest point of contact between the
door and the door gasket, if that area can
be occupied by clothing during washer
operation. Similarly, for top-loading
hojjhrizontal-axis clothes washers, the
water fill volume would include any
space above the plane of the door hinge,
if that area can be occupied by clothing
during washer operation. This
additional clarification is consistent
with the illustrations for these clothes
washer types provided in DOE’s
guidance document.
2. Capacity Measurement in Appendix
J2
Section 3.1.4 of appendix J2 specifies
the maximum allowable water fill levels
for determining the capacity of toploading and front-loading clothes
washers. For front-loading horizontalaxis clothes washers, section 3.1.4
specifies filling the clothes container to
the ‘‘uppermost edge that is in contact
with the door seal.’’ DOE intended this
language to clarify the text in DOE’s July
6, 2010 guidance document interpreting
appendix J1, but did not intend for the
measured capacity values to differ.
Since publishing the March 2012 final
rule, DOE has become aware of frontloading clothes washer door geometries
with complex curvatures that may not
have an easily discernible ‘‘uppermost
edge’’ in contact with the door seal.
Therefore, DOE proposes to amend the
description of the maximum fill volume
for front-loading clothes washers using
the same language as the proposed
amendments in appendix J1 and
specified in the July 6, 2010 guidance,
as described in the previous section.
The proposed revision would provide
additional clarity by referencing the
‘‘highest point of contact’’ rather than
the ‘‘uppermost edge,’’ and will more
E:\FR\FM\25APP2.SGM
25APP2
23064
Federal Register / Vol. 79, No. 80 / Friday, April 25, 2014 / Proposed Rules
clearly identify the geometric boundary
between the door and the door gasket.
The proposal would more clearly define
the uppermost fill level for a wider
range of front-loading clothes washer
geometries. As noted above, DOE
intends for the measured capacity of a
front-loading clothes washer using the
proposed revised language to be
equivalent to the measured capacity
using the current front-loading capacity
language in section 3.1.4 of appendix J2.
The proposed amendments to
appendix J2 also incorporate
illustrations of the boundary defining
the uppermost edge of the clothes
container for top-loading vertical-axis
clothes washers and the boundaries
defining the fill volumes for horizontalaxis clothes washers.

3. Capacity Rounding Requirements
In both appendix J1 and appendix J2,
the capacity measurement is used to
determine the test load sizes as defined
in Table 5.1. The table provides test
load sizes for capacity ranges in
increments of 0.10 cubic feet. The
precision of the capacity ranges in Table
5.1 implies that the capacity of the
clothes container must be measured to
the nearest 0.01 cubic foot for the
purpose of determining load size.
However, manufacturers typically report
capacity to the nearest 0.1 cubic foot in
DOE certification reports and in retail
advertisements.
The proposed amendments clarify
that, under appendix J1 and appendix
J2, capacity must be measured to the
nearest 0.01 cubic foot not only for the
purpose of determining load size, but
also for the purpose of calculating the
values that manufacturers must report
pursuant to 10 CFR 429.20(b). In both
appendices, DOE proposes specifying
this requirement in a new section 3.1.7
following the calculation of capacity in
newly renumbered section 3.1.6.
The proposed amendments would
also specify in a new section at 10 CFR
429.20(c) that capacity must be reported
to the nearest 0.1 cubic foot (cu. ft.) for
the purpose of DOE certification reports
for residential clothes washers.
Finally, DOE proposes to clarify in a
new section at 10 CFR 429.20(a)(3) that
the certified capacity of any clothes
washer basic model shall be the mean
of the capacities of the units in the
sample for the basic model. While DOE
believes this is current practice because
the existing test procedure and sampling
plan require testing at least two units
and measuring the drum capacity
individually for each, DOE is proposing
this amendment for clarity.

4. Plastic Sheet Material
Section 3.1.2 of both appendix J1 and
appendix J2 instructs the testing party to
line the inside of the clothes container
with a 2 mil thickness (0.051mm)
plastic sheet in preparation for
performing the capacity measurement.
DOE is aware that common industry
practice is to use a large 2 mil plastic
bag, rather than a plastic sheet, for
lining the clothes container because the
shape of the plastic bag more easily
conforms to the geometry of the clothing
container. DOE believes the measured
capacity of the clothes washer would be
the same regardless of whether a plastic
sheet or plastic bag is used, provided
that the thickness of either the plastic
sheet or plastic bag is 2 mil. DOE
therefore proposes to amend section
3.1.2 of both appendix J1 and appendix
J2 to allow the use of either a 2 mil
thickness plastic sheet or plastic bag to
line the inside of the clothes container.
5. Shipping Bolts
Typically, front-loading clothes
washers are designed with large bolts,
inserted through the back of the clothes
washer, that secure the wash drum to
prevent movement of the drum during
shipping. These ‘‘shipping bolts’’ must
be removed prior to operating the
clothes washer. Alternatively, on some
front-loading clothes washers, the drum
is secured using other forms of bracing
hardware that is intended to be removed
prior to operating the clothes washer.
Section 3.1.1 of appendix J2 currently
specifies that the shipping bolts must
remain in place during the capacity
measurement procedure to support the
wash drum and prevent it from sagging
downward as the drum is filled with
water. The proposed amendments
would add a reference to ‘‘other forms
of bracing hardware’’ in section 3.1.1 of
both appendix J1 and appendix J2.
In addition, DOE has become aware of
front-loading clothes washer designs
that do not use shipping bolts or other
forms of bracing hardware to support
the wash drum during shipping. DOE
proposes further amending section 3.1.1
of both appendix J1 and J2 to describe
how a laboratory should measure the
capacity of this type of clothes washer.
The proposed amendments would allow
a laboratory to support the wash drum
by other means, including temporary
bracing or support beams. Any
temporary bracing or support beams
would be required to keep the wash
drum in a fixed position, relative to the
geometry of the door and door seal
components, that is representative of the
position of the wash drum during
normal operation. The proposal would
PO 00000
Frm 00004
Fmt 4701
Sfmt 4702
also require that the method used avoid
damage to the unit that would affect the
results of the energy and water testing.
The proposed amendments further
specify that the test report must fully
document the method used to support
the wash drum, and pursuant to 10 CFR
429.71, the manufacturer must retain
such documentation as part of its test
records.
B. Hot and Cold Water Supply Test
Conditions
Section 2.3.1 of both appendix J1 and
appendix J2 specifies that the
temperature of the hot water supply
must not exceed 135 °F and the cold
water supply must not exceed 60 °F for
clothes washers in which electrical
energy or water energy consumption are
affected by the inlet water temperature
(for example, water heating clothes
washers or clothes washers with
thermostatically controlled water
valves). This specification does not
provide a lower bound for the hot and
cold water supply temperatures. In
contrast, section 2.3.2 of both test
procedures specifies a hot water supply
temperature of 135 °F ± 5 °F and a cold
water supply temperature of 60 °F ± 5
°F for clothes washers in which
electrical energy and water energy
consumption are not affected by the
inlet water temperature.
On clothes washers with
thermostatically controlled mixing
valves, the supply water temperatures
directly affect the relative quantities of
hot and cold water consumption during
a wash cycle. DOE has observed that the
large majority of residential clothes
washers on the market now use
thermostatically controlled mixing
valves or other similar technologies for
precisely controlling the wash water
temperatures. DOE’s engineering
analysis during the most recent energy
conservation standards rulemaking
indicated that precise temperature
control will be required to achieve the
higher efficiency levels established by
the May 31, 2012 direct final rule. (77
FR 32308)
To improve consistency and
repeatability of test results, DOE
proposes to establish a lower bound of
130 °F for the hot water supply and 55
°F for the cold water supply for clothes
washers in which electrical energy or
water energy consumption are affected
by the inlet water temperature. This
would provide an allowable range of
five degrees on the hot and cold water
supplies (i.e., 130–135 °F and 55–60 °F,
respectively). This amendment would
apply to both appendix J1 and appendix
J2 (with section 2.3.1 in appendix J2
renumbered to 2.2.1).
E:\FR\FM\25APP2.SGM
25APP2
Federal Register / Vol. 79, No. 80 / Friday, April 25, 2014 / Proposed Rules
DOE notes that the proposed fivedegree temperature tolerance is a tighter
tolerance than is required for clothes
washers in which electrical energy and
water energy consumption are not
affected by the inlet water temperature;
however, DOE notes that the water
supply temperature affects the outcome
of the MEF results when testing clothes
washers with thermostatically
controlled water valves more
significantly than for clothes washers
without such valves. DOE requests
comment on the potential test burden
associated with maintaining a tolerance
of five degrees on the hot and cold water
supply temperature for clothes washers
in which electrical energy and water
energy consumption are affected by the
inlet water temperature.
C. Test Cloth Standard Extractor RMC
Test Procedure
Sections 2.6.5 through 2.6.7 of both
appendix J1 and appendix J2 contain
the procedures for performing the
standard extractor remaining moisture
content (RMC) test to evaluate the
moisture absorption and retention
characteristics and to develop a unique
correction curve for each new lot of test
cloth. To improve the clarity and overall
logical flow of the test procedure, DOE
proposes moving the contents of
sections 2.6.5 through 2.6.7 in both
appendices to a new appendix J3 as a
standalone test method for measuring
the moisture absorption and retention
characteristics of new energy test cloth
lots.
mstockstill on DSK4VPTVN1PROD with PROPOSALS2
D. Test Cloth Loading Instructions
Section 2.8.3 of both appendix J1 and
appendix J2 instruct the testing party to
load the energy test cloths into the
clothes washer by grasping them in the
center, shaking them to hang loosely,
and then ‘‘put them into the clothes
container’’ prior to activating the clothes
washer. DOE proposes to provide
additional specificity for the test cloth
handling and loading instructions,
which DOE believes will improve the
overall clarity and consistency of test
cloth loading procedures. The proposed
amendments would apply to both
appendix J1 and appendix J2 (section
2.8.3 would be renumbered to 2.9.2 in
appendix J2 per the proposed
amendments).
DOE proposes using a modified
version of the loading instructions for
towels and pillowcases provided in the
Association of Home Appliance
Manufacturers (AHAM) HLW–1–2010
test method, Performance Evaluation
VerDate Mar<15>2010
18:42 Apr 24, 2014
Jkt 232001
Procedures for Household Appliances.1
Like DOE’s current test cloth loading
instructions, the AHAM procedure
involves grasping the towel/pillowcase
in the center and shaking it so that it
hangs loosely. The AHAM procedure
further describes placing the towels/
pillowcases into the drum with
alternating orientations. It also provides
sketches illustrating each step in the
loading process. DOE’s proposed
amendments would adopt similar
illustrations. The amendments would
also specify following any additional
manufacturing loading instructions
provided to the user regarding the
placement of clothing within the
clothing container.
E. Energy Test Cycle
1. Warm Rinse Cycles
Section 1.7 of appendix J1 defines the
energy test cycle as (A) the cycle
recommended by the manufacturer for
washing cotton or linen clothes,
including all wash/rinse temperature
selections and water levels offered in
that cycle, and (B) for each other wash/
rinse temperature selection or water
level available on that basic model, the
portion(s) of other cycle(s) with that
temperature selection or water level
that, when tested pursuant to these test
procedures, will contribute to an
accurate representation of the energy
consumption of the basic model as used
by consumers.
DOE published guidance on
September 21, 2010, clarifying that the
energy test cycle should include the
warm rinse of the cycle most
comparable to the cottons and linens
cycle if warm rinse is not available on
the cottons and linens cycle. See DOE’s
guidance document at: https://www1.
eere.energy.gov/buildings/appliance_
standards/pdfs/clotheswasher_faq_
2010-09-21.pdf. The proposed
amendments codify DOE’s guidance by
incorporating this clarification into
section 1.7(B) of appendix J1
(redesignated as section 1.8(B) due to
the proposed addition of a new entry in
the list of definitions before the energy
test cycle definition).
As described in section III.E.4 of this
NOPR, DOE is proposing a new
methodology for determining the energy
test cycle in appendix J2. Based on the
proposed methodology, which is
intended to improve clarity without
altering the cycle selections that will be
part of the energy test cycle, DOE has
tentatively determined that a parallel
clarification regarding a warm rinse
cycle is unnecessary in appendix J2.

Fmt 4701
Sfmt 4702

The methodology for determining the
warm wash/warm rinse temperature
selection in appendix J2 requires
including the warm rinse cycle if it is
not available on the cycle recommended
for washing cotton or linen clothes but
is available on an alternative cycle
selection.
2. Sanitization Cycles
As described in the previous section,
the energy test cycle in appendix J1
includes all temperature selections
available on the cycle recommended by
the manufacturer for washing cotton or
linen clothing. The energy test cycle
also includes other temperature
selections available on other cycles that
‘‘will contribute to an accurate
representation of the energy
consumption of the basic model as used
by consumers.’’
Section 3.3 of appendix J1 defines the
‘‘Extra Hot Wash’’ as a cycle with a
maximum wash temperature of greater
than 135 °F on water heating clothes
washers. DOE is aware that on some
clothes washers, an extra hot
temperature selection is available only
on a separate sanitization cycle. The
proposed amendments to the energy test
cycle definition in appendix J1 would
clarify that for such clothes washers, the
sanitization cycle should be included in
the energy test cycle if the cycle is
recommended by the manufacturer for
washing clothing and if doing so would
contribute to an accurate representation
of the energy consumption as used by
consumers. If the extra hot temperature
selection is available only on a
sanitization cycle not recommended by
the manufacturer for washing clothing
(e.g., a cycle intended only for sanitizing
the wash drum), such a cycle would not
be required for consideration as part of
the energy test cycle.
Based on DOE’s proposed new
methodology for determining the energy
test cycle in appendix J2, DOE has
tentatively determined that a specific
clarification regarding a sanitization
cycle is unnecessary in appendix J2
because the methodology for
determining the extra hot wash
temperature selection requires including
the extra hot wash temperature setting
if such a setting is available on the
clothes washer and is recommended by
the manufacturer for washing clothing.
3. Default Cycle Settings
Testing a clothes washer according to
appendix J1 or appendix J2 requires
selecting specific wash/rinse
temperatures and wash water fill levels
for the wash cycles used to determine
energy and water consumption. In
addition, specific spin speeds must be

Federal Register / Vol. 79, No. 80 / Friday, April 25, 2014 / Proposed Rules
mstockstill on DSK4VPTVN1PROD with PROPOSALS2
selected for the wash cycle(s) used to
determine the remaining moisture
content. Other than these settings, the
test procedure does not instruct the user
to change any other optional settings
during testing.
The proposed amendments to
appendix J1 would modify section
1.7(B) (redesignated as 1.8(B)) to clarify
the requirement to use the manufacturer
default settings for any cycle selections,
except for (1) the temperature selection,
(2) the wash water fill levels, or (3) if
necessary, the spin speeds on wash
cycles used to determine remaining
moisture content. Specifically, the
manufacturer default settings must be
used for wash conditions such as
agitation/tumble operation, soil level,
spin speed on wash cycles used to
determine energy and water
consumption, wash times, rinse times,
optional rinse settings, water heating
time for water-heating clothes washers,
and all other wash parameters or
optional features applicable to that wash
cycle. Any optional wash cycle feature
(other than wash/rinse temperature,
water fill level selection, or spin speed
on cycle selections used to determine
remaining moisture content) that is
activated by default on the wash cycle
under test must be included for testing
unless the manufacturer instructions
recommend not selecting this option for
washing normally soiled cotton or linen
clothes.
The proposed amendments to
appendix J2 would add a new section
3.2.7 to address the use of default cycle
settings in the same manner as the
modification proposed for appendix J1.
DOE believes the new section 3.2.7 is
the most appropriate location for this
amendment in appendix J2 in
conjunction with the revised structure
of the energy test cycle definition and
flowcharts in appendix J2.
4. Energy Test Cycle Definition and
Flowcharts
DOE notes that appendix J1 uses the
term ‘‘energy test cycle’’ in two different
ways. In some instances, ‘‘energy test
cycle’’ refers to the complete set of
wash/rinse temperature selections
required for testing. In other instances,
‘‘energy test cycle’’ refers to the single
wash cycle under test. DOE does not
propose changing its usage of the term
‘‘energy test cycle’’ in appendix J1. In
each instance where the term ‘‘energy
test cycle’’ is used, the specific meaning
of the term can be determined through
context.
In appendix J2, however, DOE
proposes to simplify the definition of
the energy test cycle so that it means the
complete set of wash/rinse temperature
VerDate Mar<15>2010
18:42 Apr 24, 2014
Jkt 232001
selections required for testing. The
individual wash/rinse temperature
selections required for testing would be
determined using a new methodology as
described below. The provisions within
parts (D) and (E) of the current energy
test cycle definition would be moved to
sections 3.2.7 and 3.2.8, respectively,
which is a more appropriate location
within the test procedure. Additionally,
throughout appendix J2, DOE proposes
to provide greater consistency in its
usage of the term ‘‘energy test cycle,’’
such that when used, it refers only to
the entire set of wash/rinse temperature
selections required for testing. In
instances where the test procedure
currently uses the term ‘‘energy test
cycle’’ to refer to an individual wash
cycle, DOE proposes to use the generic
term ‘‘wash cycle’’ or other similar
terminology as appropriate for each
instance. DOE also proposes to improve
overall clarity by providing the full
wash/rinse temperature designation (e.g.
‘‘Cold wash/Cold rinse’’) throughout the
test procedure.
In conjunction with the simplified
energy test cycle definition, DOE
proposes a new approach to
determining the wash/rinse temperature
selections required for testing in
appendix J2. DOE proposes to translate
the current methodology for
determining the energy test cycle into a
set of flowcharts that testing parties
would use to determine each wash/rinse
temperature selection to be used for
testing. DOE believes that the binary
nature of each decision box within the
flowcharts would provide increased
clarity and ease of use in determining
which wash/rinse temperature settings
to use for testing. DOE proposes to
include these flowcharts within newly
renumbered section 2.12 in appendix J2.
Because the proposed flowcharts
would incorporate more precise
definitions of warm and cold rinse
temperatures, DOE also proposes to
clarify the definition of ‘‘cold rinse’’ in
appendix J2 so that it means the coldest
rinse temperature available on the
machine, as indicated to the user on the
clothes washer control panel. This
would prevent the unintended
consequence of a wash/rinse
temperature designation being excluded
from the energy test cycle if the rinse
portion of the cycle included a small
amount of hot water (thus raising the
rinse temperature slightly higher than
the coldest rinse available on the
machine), but was indicated on the
control panel as being a cold rinse
paired with the selected wash
temperature.
In addition, DOE proposes adding a
new definition in appendix J2 for
PO 00000
Frm 00006
Fmt 4701
Sfmt 4702
‘‘Normal cycle,’’ which would be
defined as: ‘‘Normal cycle means the
cycle selection recommended by the
manufacturer as the most common
consumer cycle for washing a full load
of normally to heavily soiled cotton
clothing. For machines where multiple
cycle settings meet this description,
then the Normal cycle is the cycle
selection that results in the lowest IMEF
or MEF value.’’ ’’. DOE first adopted a
similar definition of ‘‘Normal cycle’’ for
clothes washer testing in appendix J,
which incorporated the general
approach to calculating the energy
consumption of automatic clothes
washers contained in AHAM’s standard
HLW–2EC for clothes washers at the
time. (42 FR 25329, 25330 (May 17,
1977); 42 FR 49802 (September 28,
1977)) Over time, machine labeling and
literature evolved to the point that the
term ‘‘normal’’ as previously defined no
longer captured all of the control
settings most consumers would
typically choose in operating the
machine to wash their laundry. (See,
e.g., 75 FR 57556, 57575) Further, the
range of cycle options and terminology
on the control panels have changed
such that many machines no longer
refer to a ‘‘Normal’’ cycle, instead
relying upon other terms. This evolution
may have resulted in inaccurate
representations of the energy usage of
these machines due to differing
interpretations regarding the
appropriate test cycle. In order to add
clarity and ensure consistent selection
of the appropriate cycle for energy
testing, DOE is proposing to add the
‘‘Normal cycle’’ definition in newly
designated section 1.25 and to reference
the term in the new energy test cycle
flowcharts, and DOE will consider
manufacturer literature and markings on
the machine when determining the
normal cycle of any particular unit. DOE
specifically seeks comment on this
definition and whether it adequately
covers the cycle setting most commonly
chosen by users of washing machines.
DOE also proposes to remove the
definitions for ‘‘warm rinse’’ and ‘‘warm
wash’’ from section 1 of appendix J2
(Definitions and Symbols), since those
terms would be defined in the proposed
flowcharts instead.
Finally, DOE proposes to move the
current section 2.13 of appendix J2,
Energy consumption for the purpose of
certifying the cycle selection(s) to be
included in Part (B) of the energy test
cycle definition, to newly created
section 3.10. Section 3 of appendix J2
(Test Measurements), is a more
appropriate location in the test
procedure for these provisions.
E:\FR\FM\25APP2.SGM
25APP2
Federal Register / Vol. 79, No. 80 / Friday, April 25, 2014 / Proposed Rules
DOE intends for the cycle selections
as determined using the new energy test
cycle flowcharts to be the same as the
cycle selections as determined using the
current energy test cycle definition in
appendix J2. DOE requests comment on
whether discrepancies exist when
determining the wash/rinse temperature
selections using the proposed
flowcharts compared to using the
current energy test cycle definition. If
discrepancies exist, DOE requests that
interested parties provide specific
examples of cycle setting configurations
that would lead to the discrepancies.
DOE also requests comment on whether
the methodology presented in the
flowcharts could result in an efficiency
rating that is unrepresentative of how a
particular clothes washer would be used
by consumers.
F. Wash Time Setting
DOE proposes moving the wash time
setting provisions from section 2.10 of
appendix J2 to a subsection of newly
revised section 3.2.5. The procedure for
setting the wash time must be
performed prior to each individual wash
cycle during testing; therefore, the most
appropriate location for this instruction
is within the specific testing procedures
provided in section 3.2.
mstockstill on DSK4VPTVN1PROD with PROPOSALS2
G. Standby and Off Mode Testing
DOE proposes clarifications to the
standby and off mode power testing
provisions in appendix J2. In addition to
minor wording clarifications in sections
3.9 and 3.9.1 of appendix J2, the
proposed clarifications are as follows:
1. Testing Sequence
DOE proposes clarifying that
combined low-power mode testing in
section 3.9 of appendix J2 be performed
after completion of an energy test cycle,
after removing the test load, and
without disconnecting the electrical
energy supply to the clothes washer
between completion of the energy test
cycle and the start of combined lowpower mode testing. This clarification
would preclude performing combined
low-power mode testing directly after
connecting the clothes washer to the
electrical energy supply. DOE testing
suggests that testing a clothes washer’s
standby or off-mode power
consumption directly after connecting
the clothes washer to the electrical
energy supply may not be representative
of the standby or off-mode power
consumption after its first use. DOE
believes this clarification would ensure
that the results of the combined lowpower mode testing accurately represent
the conditions most likely to be
experienced in a residential setting.
VerDate Mar<15>2010
18:42 Apr 24, 2014
Jkt 232001
2. Default Settings
DOE proposes clarifying that
combined low-power mode testing be
performed without changing the control
panel settings used for the energy test
cycle completed prior to combined lowpower mode testing. The test procedure
requires using the manufacturer default
settings for any wash cycle performed
within the energy test cycle. The
proposed clarification would preclude
activating or deactivating any optional
control panel displays or other features
not activated by default on the clothes
washer when it is not being used to
perform an active mode wash cycle,
during combined low-power mode
testing. DOE believes this clarification
would ensure that the results of the
combined low-power mode testing
accurately represent the conditions most
likely to be experienced in a residential
setting.
3. Multiple Possible Inactive Modes
DOE testing indicates that some
residential appliances, including clothes
washers, may have multiple modes that
meet the definition of inactive mode
currently provided in section 1.15 of
appendix J2 (redesignated section 1.16).
DOE proposes clarifying that inactive
mode is the lowest-power standby mode
that facilitates the activation of active
mode by remote switch (including
remote control), internal sensor, or
timer, or that provides continuous status
display. Specifying use of the lowestpower mode would clarify potential
ambiguity regarding which inactive
mode to use for testing if multiple
inactive modes exist on a clothes
washer.
H. Fixed Water Fill Control Systems
The load sizes used for testing depend
upon the type of water fill control
system available on the clothes washer,
as defined in section 2.8 of both
appendix J1 and appendix J2. For
clothes washers with manual water fill
control systems, the minimum and
maximum load sizes are tested. For
clothes washers with adaptive water fill
control systems, the minimum, average,
and maximum load sizes are tested.
DOE has become aware of clothes
washers that have fixed water levels for
all load sizes and no water fill selector
or water fill control settings available to
the user. DOE notes that, as with
adaptive water fill control systems,
fixed water fill control systems do not
require user action to determine the
water fill level. Therefore, DOE
proposes that a clothes washer with a
fixed water fill control system be tested
in the same manner as a clothes washer
PO 00000
Frm 00007
Fmt 4701
Sfmt 4702
23067
with an adaptive water fill control
system; i.e., using the minimum,
average, and maximum load sizes.
The proposed amendments would (1)
add a definition for ‘‘fixed water fill
control system,’’ (2) add a definition for
‘‘automatic water fill control system,’’
which would include both fixed water
fill control systems and adaptive water
fill control systems, and (3) amend the
definition of ‘‘adaptive water fill control
system’’ to clarify that it is considered
a type of automatic water fill control
system. Additionally, where
appropriate, instances of ‘‘adaptive
water fill control system’’ throughout
the test procedure would be replaced
with ‘‘automatic water fill control
system,’’ to indicate that such testing
provisions apply to both adaptive water
fill control systems and fixed water fill
control systems. These amendments
would apply to both appendix J1 and
appendix J2.
I. Deep Rinse and Spray Rinse
Definitions
Section 3.2.2 of appendix J2 states
that total water consumption during the
energy test cycle shall be measured,
including hot and cold water
consumption, during wash, deep rinse,
and spray rinse. As proposed, the
revised section 3.2.8 would specify
including the entire active washing
mode, and excluding any delay start or
cycle finished modes, for each wash
cycle tested. Active washing mode is
defined in section 1.2 as including the
main functions of washing, soaking,
tumbling, agitating, rinsing, and/or
removing water from the clothing. DOE
believes that the proposed revision to
3.2.8 provides better clarity and
completeness, compared to the wording
in 3.2.2, regarding the portions of the
wash cycle to be included and measured
for testing. Therefore, DOE proposes to
delete section 3.2.2 from appendix J2
and to renumber the subsequent
subsections accordingly.
Furthermore, since section 3.2.2 is the
only location within the test procedure
where the terms ‘‘deep rinse’’ and
‘‘spray rinse’’ occur, DOE also proposes
to remove those two definitions from
the section 1 of appendix J2.
J. Uniformly Distributed Warm Wash
Temperatures
Section 1.17 of appendix J1 and
section 1.32 of appendix J2 provide the
definition of uniformly distributed
warm wash temperature selections. A
clothes washer has uniformly
distributed warm wash temperature
selections if (A) the warm wash
temperatures have a linear relationship
with all discrete warm wash selections
E:\FR\FM\25APP2.SGM
25APP2
mstockstill on DSK4VPTVN1PROD with PROPOSALS2
23068
Federal Register / Vol. 79, No. 80 / Friday, April 25, 2014 / Proposed Rules
when the water temperatures are plotted
against equally spaced consecutive
warm wash selections between the
hottest warm wash and the coldest
warm wash, and the mean water
temperature of the warmest and the
coldest warm selections coincide with
the mean of the hot wash and cold wash
water temperatures within ±3.8 °F; or
(B) on a clothes washer with only one
warm wash temperature selection, the
warm wash temperature selection has a
water temperature that coincides with
the mean of the hot wash and cold wash
water temperatures within ±3.8 °F. For
clothes washers with uniformly
distributed warm wash temperature
selections, the reported values to be
used for the warm wash setting are the
arithmetic average of the measurements
for the hot and cold wash selections.
This is a ‘‘shortcut’’ calculation only; no
testing is required.
DOE notes that the criteria for
determining whether the warm wash
temperatures are uniformly distributed
are based on water temperature only;
total water consumption is not
considered. On a clothes washer with
electronic control systems, a clothes
washer’s warm wash cycles could be
programmed to use larger quantities of
water than the cold wash and hot wash
cycles, yet the data to be used to
represent the warm wash cycle would
be the average of the cold and hot wash
cycles, rather than actual data from
testing. Since the warm wash
temperature selection has the highest
temperature use factor at 0.49, DOE
proposes that the warm wash
temperature selection(s) on such a
clothes washer be tested. Therefore,
DOE proposes to remove the definition
of uniformly distributed warm wash
temperature selections from both
appendix J1 and appendix J2, and to
remove any provisions within the test
procedures pertaining to uniformly
distributed warm wash temperature
selections.
DOE requests comment on any
potential increase in test burden as
result of its proposal to eliminate the
separate testing provisions for clothes
washers with uniformly distributed
warm wash temperatures. DOE
estimates that the resulting total testing
time would be no greater than for
clothes washers with the same number
of warm wash temperature options, but
with non-uniformly distributed
temperatures, which DOE observes
constitutes the majority of the market.
K. Determining Extra Hot Wash
Temperature
Section 3.3 of both appendix J1 and
appendix J2 defines Extra Hot Wash as
VerDate Mar<15>2010
18:42 Apr 24, 2014
Jkt 232001
having a maximum wash temperature
greater than 135 °F. Determining the
maximum wash temperature requires
measuring the water temperature during
the wash cycle to determine the
maximum wash temperature achieved.
DOE understands that, in practice,
measuring the wash water temperature
can be difficult due to factors such as
the geometry of front-loading tub
design; the increasing use of door locks;
and, in high-efficiency clothes washers,
the lack of a standing pool of wash
water from which to measure the
temperature.
DOE proposes adding a statement to
section 3.3 of both appendix J1 and
appendix J2 to provide guidance on one
possible method that testing parties
could use to determine the maximum
wash water temperature. In the
proposed method, testing parties would
adhere non-reversible temperature
indicator labels to the inside of the
clothing container to determine the
maximum water temperature during an
energy test cycle. If a testing party used
the temperature indicator label method
when testing a front-loading clothes
washer, the label would be adhered
along the inner circumference of the
clothes container drum, midway
between the front and the back of the
clothes container. For a top-loading
clothes washer, the label would be
adhered along the inner circumference
of the clothes container drum, as close
to the bottom of the container as
possible.
Manufacturers may be able to use
alternate methods for determining the
maximum wash temperature during an
energy test cycle; however, DOE is
unaware of any other direct
measurement methods that could be
safely used by a third-party laboratory
without requiring partial disassembly of
the clothes washer or without
permanently altering the machine.
L. Gas-Heated and Oil-Heated Hot
Water Energy
Section 4.1.4 of both appendix J1 and
appendix J2 provides equations for
calculating per-cycle hot water energy
consumption using gas-heated or oilheated water. The result of this
calculation is not used in any
downstream calculations within the test
procedure. The calculated result is
referenced within 10 CFR
430.23(j)(1)(i)(B) and (ii)(B); however,
these values are not included as part of
DOE’s certification requirements for
clothes washers in 10 CFR 429.20 and
429.46, nor are they required for other
DOE regulatory purposes. DOE is
unaware of any other regulatory
programs that require the calculation of
PO 00000
Frm 00008
Fmt 4701
Sfmt 4702
per-cycle hot water energy using gas- or
oil-heated water for clothes washers.
Therefore, DOE proposes to remove
section 4.1.4 from both appendix J1 and
appendix J2, and to remove the related
sections of 10 CFR 430.23(j)(1)(i)(B) and
(ii)(B), adjusting the subsequent section
numberings accordingly.
M. Out-of-Balance Loads
DOE has observed that some clothes
washers may terminate the wash cycle
prematurely if an out-of-balance
condition is detected. Because the test
procedure defines an energy test cycle
as including the agitation/tumble
operation, spin speed(s), wash times,
and rinse times applicable to each cycle,
the data from a wash cycle that
terminates prematurely if an out-ofbalance condition is detected, and thus
does not include these required
elements, should be discarded. The
proposed amendments provide this
clarification to section 3.2 of appendix
J1 and a new section 3.2.9 of appendix
J2.
N. Reordering of Section 2, Testing
Conditions
DOE proposes to reorder the
subsections within section 2 of
appendix J2 (Testing Conditions) to
improve the clarity and overall flow of
the section. After reordering, the general
progression of section 2 would be as
follows:
• Laboratory infrastructure
requirements
• Instrumentation requirements
• Test cloth requirements
• Test load composition and handling
• Clothes washer installation and
preconditioning procedures
• Energy test cycle determination
O. Table 3.2 Edits
Table 3.2 in both appendix J1 and
appendix J2 defines the sections within
the test procedure that govern the tests
of particular clothes washers, based on
the number of wash/rinse temperature
selections available on the model. DOE
proposes to clarify one of the headings
in Table 3.2 of appendix J1. The
proposal would amend the current
heading, ‘‘Number of wash temp.
selections’’ to ‘‘Number of wash temp.
selections in the energy test cycle.’’ In
addition, Table 3.2 in appendix J1
contains a typographical error in the
second footnote: the word ‘‘heating’’ is
misspelled. Today’s proposal corrects
this error.
DOE proposes simplifying the overall
structure of Table 3.2 in appendix J2
(renumbered 3.2.2) by using the
clarified wash/rinse temperature
nomenclature within the revised energy
E:\FR\FM\25APP2.SGM
25APP2
Federal Register / Vol. 79, No. 80 / Friday, April 25, 2014 / Proposed Rules
test cycle definition and flowcharts.
DOE does not intend for any of the
required test sections to change as a
result of the proposed revisions to the
table.
P. Table 4.1.1 Edits
Table 4.1.1 in appendix J2 provides
the temperature use factors. DOE
proposes improving the clarity of the
overall structure of Table 4.1.1 in
appendix J2 by reorganizing the
columns in the table to more closely
match the wash/rinse temperature
nomenclature within the revised energy
test cycle definition and flowcharts.
DOE does not intend for any of the
temperature use factors to change as a
result of the proposed revisions to the
table.
mstockstill on DSK4VPTVN1PROD with PROPOSALS2
Q. Table 2.8 Edits
In the March 2012 final rule, Table 2.8
in appendix J2 (‘‘Test Load Sizes and
Water Fill Settings Required’’)
contained a formatting error that
combined the average and minimum
test load sizes into a single row for
clothes washers with an adaptive water
fill control system. DOE did not intend
to amend the test load sizes required for
clothes washers with an adaptive water
fill control system. Today’s proposal
amends the layout of Table 2.8 in both
appendix J1 and appendix J2 to improve
its overall clarity. As described above,
DOE has also proposed changing the
heading of the relevant column to
‘‘automatic water fill control system’’
rather than ‘‘adaptive water fill control
system’’.
R. Replacing ‘‘Consumer’’ With ‘‘User’’
Both appendix J1 and appendix J2
refer to the ‘‘consumer’’ in various parts
of the test procedures. In each instance,
the word ‘‘consumer’’ refers to the
individual using the clothes washer.
DOE notes that the word ‘‘consumer’’
may be misconstrued as the original
purchaser or owner of the clothes
washer. In some cases, particularly coinoperated laundries and multi-family
housing common laundry rooms, the
purchaser or owner of the clothes
washer is not the end user of the clothes
washer.
The distinction between the owner
and the end user may be relevant to the
test procedure if certain settings, such as
water fill levels, may be customized by
the owner of the clothes washer but are
not adjustable by the end user. To
prevent any possible ambiguity implied
by the word ‘‘consumer,’’ DOE proposes
2 Corrected RMC measurements are obtained
using the test cloth correction factors developed for
each test cloth lot, as applied in section 2.6.7 of
VerDate Mar<15>2010
18:42 Apr 24, 2014
Jkt 232001
to replace the word ‘‘consumer’’ with
‘‘user’’ or ‘‘end user’’ throughout the test
procedure in all instances where the
word ‘‘consumer’’ is currently used.
S. Introductory Text
DOE proposes revising the
introductory text after the appendix
headings in both appendix J1 and
appendix J2 to clarify the proper use of
appendices J1 and J2 for making
representations of energy efficiency,
including certifying compliance with
DOE energy conservation standards.
DOE test procedures for clothes
washers are set forth in appendices J1
and J2 in 10 CFR Part 430 subpart B.
This proposal describes amendments to
both appendices. Pursuant to 42 U.S.C.
6293(c), manufacturers must make
representations of energy efficiency
using any amendments DOE adopts in a
final test procedure rule beginning 180
days after the effective date of such rule.
Therefore, beginning 180 days after the
effective date of any final amendments
based on today’s proposals,
manufacturers must make
representations of energy efficiency
pursuant to appendix J1 or appendix J2
as modified through such amendments.
In addition, as of March 7, 2015,
manufacturers of residential clothes
washers will no longer be authorized to
use appendix J1. Residential clothes
washer manufacturers must use
appendix J2, as modified though any
amendments that DOE may adopt based
on today’s proposal, to demonstrate
compliance with the standards and
make any representations of energy
efficiency as of March 7, 2015. March 7,
2015 is the compliance date of the
amended energy conservation standards
that address standby and off mode
energy consumption for residential
clothes washers. 77 FR 32308 (May 31,
2012) and 77 FR 59719 (October 1,
2012).
T. Test Procedure Provisions in 10 CFR
430.23
DOE proposes revising section
430.23(j)(3) to contain only the
provisions for calculating annual water
consumption when using either
appendix J1 or appendix J2. The
proposed amendments would add a new
section 430.23(j)(4), which would
contain the provisions for determining
water factor and integrated water factor.
The proposed amendments would
also create a new section 430.23(j)(5)
that would contain the following
statement: ‘‘Other useful measures of
appendix J1 and appendix J2. DOE publishes a list
of the test cloth correction factors developed for test
cloth Lots 5 through 20 at https://www2.eere.energy.
PO 00000

energy consumption for automatic or
semi-automatic clothes washers shall be
those measures of energy consumption
that the Secretary determines are likely
to assist consumers in making
purchasing decisions and that are
derived from the application of
appendix J1 or appendix J2, as
appropriate.’’ This statement is
currently contained in section
430.23(j)(3). Moving the statement to a
dedicated subsection would maintain
consistency with DOE’s test procedure
provisions for other products within 10
CFR Part 430. DOE notes that the
measurement or reporting of any
additional measures of energy or water
consumption would be adopted through
the rulemaking process.
Finally, to eliminate any potential
ambiguity, the proposed amendments
would replace the phrase ‘‘can be
determined’’ with ‘‘must be
determined’’ throughout the text of 10
CFR 430.23(j)(3) through (j)(5).
U. Reporting and Verification
Requirements
1. Remaining Moisture Content
DOE has observed the potential for
significant variation in the RMC
measurement at the maximum spin
speed setting on some clothes washer
models. During testing of front-loading
clothes washer models, DOE observed
that the maximum target spin speed
may not be achieved during the final
spin portion of the cycle if the load size
is not evenly distributed around the
circumference of the wash drum. DOE
believes that in such cases, the spin
speed may be automatically reduced as
a safety precaution and to prevent
damage to the clothes washer caused by
the asymmetric rotation of the
unbalanced load within the wash
basket.
Figure III.1 shows an example of RMC
test data obtained from one frontloading residential clothes washer
model. DOE performed the RMC
measurement using the cold wash cycle
at the maximum available spin speed
setting. The RMC measurement was
performed a total of twelve times using
three different test cloth lots. The
corrected RMC measurement 2 varied
between 32.3 percent and 46.2 percent,
with an average of 37.0 percent. DOE
has observed similar variations of this
magnitude on multiple front-loading
clothes washer models.

The RMC measurement is used to
determine the per-cycle energy
consumption for removal of moisture
from the test load; i.e., the ‘‘drying
energy’’ portion of the MEF and
Integrated Modified Energy Factor
(IMEF) calculations. The drying energy
represents between 59 and 87 percent of
a clothes washer’s total energy
consumption; 3 hence, the RMC
measurement significantly impacts the
overall MEF and IMEF calculations. For
example, the level of RMC variation
shown in Figure III.1 would lead to a 25
percent variation in the overall MEF
calculation.
In today’s rule, DOE proposes adding
a new section 3.8.5 in both appendix J1
and appendix J2 to specify that
manufacturers may perform up to two
additional replications of the RMC
measurement, for a total of three
independent RMC measurements for the
tested unit, and use the average of the
three measurements as the basis for the
calculation of per-cycle energy
consumption for removal of moisture
from the test load.
DOE also proposes to add the RMC
measurement to the list of public
product-specific information contained
in the certification reports for
residential clothes washers, as described
in 10 CFR 429.20(b)(2)(i) and (ii). DOE
also proposes in newly created 10 CFR

429.20(a)(4) that the certified RMC value
of any clothes washer basic model shall
be the mean of the final RMC value
measured for all tested units of the basic
model.
Finally, DOE proposes to add
provisions in newly created section 10
CFR 429.134(c)(1) specifying that during
assessment or enforcement testing, the
measured RMC value of a tested unit
will be considered the tested unit’s final
RMC value if the measured RMC value
is within two RMC percentage points of
the certified RMC value of the basic
model (expressed as a percentage), or if
the measured RMC value is lower than
the certified RMC value. DOE proposes
a threshold of two RMC percentage
points because such a variation would
limit the variation in the overall MEF or
IMEF calculation to roughly five
percent.
If the measured RMC value of a tested
unit is more than two RMC percentage
points higher than the certified RMC
value of the basic model, DOE will
perform two additional replications of
the RMC measurement, each pursuant to
the provisions of newly added section
3.8.5 of appendix J1 and appendix J2,
for a total of three independent RMC
measurements of the tested unit. The
average of the three RMC measurements
will be considered the tested unit’s final
RMC value and will be used as the basis
for the calculation of per-cycle energy
consumption for removal of moisture
from the test load for that unit.

2. Rounding Requirements for All
Reported Values
DOE proposes adding a new section at
10 CFR 429.20(c) to specify the
rounding requirements of all reported
values for residential clothes washers as
follows: MEF and IMEF to the nearest
0.01 cu ft/kWh/cycle, WF and IWF to
the nearest 0.1 gal/cycle/cu ft, RMC to
the nearest 0.1 percentage point, and
clothes container capacity to the nearest
0.1 cu ft.
3. Energy Test Cycle Selections
As amended by the March 2012 final
rule, 10 CFR 429.20(b)(3) requires
certification reports based on testing
conducted in accordance with appendix
J2 to include a list of all cycle selections
comprising the complete energy test
cycle for each basic model. DOE
believes that this reporting requirement
should also pertain when appendix J1 is
used, particularly due to the difference
in wording of the energy test cycle
definition in appendix J1. Therefore,
DOE proposes to amend 10 CFR
429.20(b)(3) to require a list of all cycle
selections comprising the complete
energy test cycle for each basic model,
regardless of whether the certification is
based on testing conducted in
accordance with appendix J1 or
appendix J2.

B. Review Under the Regulatory
Flexibility Act
The Regulatory Flexibility Act (5
U.S.C. 601 et seq.) requires preparation
of a regulatory flexibility analysis
(IFRA) for any rule that by law must be
proposed for public comment, unless
the agency certifies that the rule, if
promulgated, will not have a significant
economic impact on a substantial
number of small entities. As required by
Executive Order 13272, ‘‘Proper
Consideration of Small Entities in
Agency Rulemaking,’’ 67 FR 53461
(August 16, 2002), DOE published
procedures and policies on February 19,
2003, to ensure that the potential
impacts of its rules on small entities are
properly considered during the DOE
rulemaking process. 68 FR 7990. DOE
has made its procedures and policies
available on the Office of the General
Counsel’s Web site: https://energy.gov/
gc/office-general-counsel.
DOE reviewed today’s proposed rule
under the provisions of the Regulatory
Flexibility Act and the procedures and
policies published on February 19,
2003. Today’s NOPR would amend
DOE’s test procedure by codifying
guidance interpreting DOE’s existing
regulations, providing further clarifying
interpretation of the relevant test
procedure provisions, correcting
formatting errors, providing improved
overall organization, and removing
certain testing provisions within the
current test procedures. DOE has
concluded that the rule would not have
a significant impact on a substantial
number of small entities. The factual
basis for this certification is as follows:
The Small Business Administration
(SBA) considers a business entity to be
a small business, if, together with its
affiliates, it employs less than a
threshold number of workers specified
in 13 CFR Part 121. These size standards
and codes are established by the 2007
North American Industry Classification
System (NAICS). The threshold number
for NAICS classification code 335224,
which applies to household laundry
equipment manufacturers and includes
residential clothes washer
manufacturers, is 1,000 employees.
VerDate Mar<15>2010
18:42 Apr 24, 2014
Jkt 232001
Searches of the SBA Web site 4 to
identify clothes washer manufacturers
within this NAICS code identified one
small business. This small business
manufactures laundry appliances,
including residential clothes washers.
DOE estimates that the clarified
description of the capacity measurement
would take the same amount of time to
conduct as the capacity measurement
analyzed in the March 2012 final rule.
DOE believes that use of an alternate
bracing method for front-loading clothes
washers that do not contain shipping
bolts or other bracing hardware is
already current practice among
manufacturers of such clothes washers.
Additionally, DOE notes that the
identified small business produces only
a single platform of top-loading clothes
washers, for which the proposed
alternate bracing method would not be
applicable.
Regarding the potential increased
testing burden associated with
maintaining a five degree tolerance on
supply water temperatures for clothes
washers in which electrical energy
consumption or water energy
consumption are affected by the inlet
water temperature. One method for
achieving this temperature tolerance
would be to use electronically
controlled water mixing valves on both
the cold and hot water supply lines.
DOE estimates a capital cost of
approximately $2,500 for installing
electronically controlled water mixing
valves on a single test stand. DOE notes
that the identified small business
currently does not manufacturer this
type of clothes washer; therefore, DOE
does not expect this proposed
amendment to require any changes to
the testing hardware currently used by
the small business.
DOE does not expect any of the
clarifications to the energy test cycle
definition or the standby and off mode
measurements to affect the total length
of testing time. Regarding any potential
increase in test burden as a result of its
proposal to eliminate the separate
testing provisions for clothes washers
with uniformly distributed warm wash
temperatures. DOE notes that the total
testing time would be no greater than for
clothes washers with the same number
of warm wash temperature options, but
with non-uniformly distributed
temperatures, which DOE observes
constitutes the majority of the market.
DOE also notes that the clothes washers
manufactured by the identified small
business do not contain uniformly

distributed warm wash temperatures,
and thus the small business will not be
affected by the proposed amendment.
Finally, the remaining proposed
changes in today’s NOPR are intended
to clarify the existing test methods
without adding any additional
requirements and therefore would not
result in additional burden.
For the reasons stated above, DOE
certifies that the proposed test
procedure amendments would not have
a significant impact on a substantial
number of small entities. DOE will
submit a certification and supporting
statement of factual basis to the Chief
Counsel for Advocacy of the SBA for
review under 5 U.S.C. 605(b).
C. Review Under the Paperwork
Reduction Act of 1995
Manufacturers of residential clothes
washers must certify to DOE that their
products comply with any applicable
energy conservation standards. In
certifying compliance, manufacturers
must test their products according to the
DOE test procedures for clothes
washers, including any amendments
adopted for those test procedures. DOE
has established regulations for the
certification and recordkeeping
requirements for all covered consumer
products and commercial equipment,
including residential clothes washers.
(76 FR 12422 (March 7, 2011). The
collection-of-information requirement
for the certification and recordkeeping
is subject to review and approval by
OMB under the Paperwork Reduction
Act (PRA). This requirement has been
approved by OMB under OMB control
number 1910–1400. Public reporting
burden for the certification is estimated
to average 20 hours per response,
including the time for reviewing
instructions, searching existing data
sources, gathering and maintaining the
data needed, and completing and
reviewing the collection of information.
Notwithstanding any other provision
of the law, no person is required to
respond to, nor shall any person be
subject to a penalty for failure to comply
with, a collection of information subject
to the requirements of the PRA, unless
that collection of information displays a
currently valid OMB Control Number.
D. Review Under the National
Environmental Policy Act of 1969
In this proposed rule, DOE proposes
test procedure amendments that it
expects will be used to develop and
implement future energy conservation
standards for residential clothes
washers. DOE has determined that this
rule falls into a class of actions that are
categorically excluded from review
E:\FR\FM\25APP2.SGM
25APP2
23072
Federal Register / Vol. 79, No. 80 / Friday, April 25, 2014 / Proposed Rules
mstockstill on DSK4VPTVN1PROD with PROPOSALS2
under the National Environmental
Policy Act of 1969 (42 U.S.C. 4321 et
seq.) and DOE’s implementing
regulations at 10 CFR Part 1021.
Specifically, this proposed rule would
amend the existing test procedures
without affecting the amount, quality or
distribution of energy usage, and,
therefore, would not result in any
environmental impacts. Thus, this
rulemaking is covered by Categorical
Exclusion A5 under 10 CFR Part 1021,
subpart D, which applies to any
rulemaking that interprets or amends an
existing rule without changing the
environmental effect of that rule.
Accordingly, neither an environmental
assessment nor an environmental
impact statement is required.
E. Review Under Executive Order 13132
Executive Order 13132, ‘‘Federalism,’’
64 FR 43255 (August 4, 1999) imposes
certain requirements on agencies
formulating and implementing policies
or regulations that preempt State law or
that have Federalism implications. The
Executive Order requires agencies to
examine the constitutional and statutory
authority supporting any action that
would limit the policymaking discretion
of the States and to carefully assess the
necessity for such actions. The
Executive Order also requires agencies
to have an accountable process to
ensure meaningful and timely input by
State and local officials in the
development of regulatory policies that
have Federalism implications. On
March 14, 2000, DOE published a
statement of policy describing the
intergovernmental consultation process
it will follow in the development of
such regulations. 65 FR 13735. DOE
examined this proposed rule and
determined that it will not have a
substantial direct effect on the States, on
the relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government. EPCA governs and
prescribes Federal preemption of State
regulations as to energy conservation for
the products that are the subject of
today’s proposed rule. States can
petition DOE for exemption from such
preemption to the extent, and based on
criteria, set forth in EPCA. (42 U.S.C.
6297(d)) No further action is required by
Executive Order 13132.
F. Review Under Executive Order 12988
Regarding the review of existing
regulations and the promulgation of
new regulations, section 3(a) of
Executive Order 12988, ‘‘Civil Justice
Reform,’’ 61 FR 4729 (Feb. 7, 1996),
imposes on Federal agencies the general
VerDate Mar<15>2010
18:42 Apr 24, 2014
Jkt 232001
duty to adhere to the following
requirements: (1) Eliminate drafting
errors and ambiguity; (2) write
regulations to minimize litigation; (3)
provide a clear legal standard for
affected conduct rather than a general
standard; and (4) promote simplification
and burden reduction. Section 3(b) of
Executive Order 12988 specifically
requires that Executive agencies make
every reasonable effort to ensure that the
regulation: (1) Clearly specifies the
preemptive effect, if any; (2) clearly
specifies any effect on existing Federal
law or regulation; (3) provides a clear
legal standard for affected conduct
while promoting simplification and
burden reduction; (4) specifies the
retroactive effect, if any; (5) adequately
defines key terms; and (6) addresses
other important issues affecting clarity
and general draftsmanship under any
guidelines issued by the Attorney
General. Section 3(c) of Executive Order
12988 requires Executive agencies to
review regulations in light of applicable
standards in sections 3(a) and 3(b) to
determine whether they are met or it is
unreasonable to meet one or more of
them. DOE has completed the required
review and determined that, to the
extent permitted by law, this proposed
rule meets the relevant standards of
Executive Order 12988.
G. Review Under the Unfunded
Mandates Reform Act of 1995
Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA) requires
each Federal agency to assess the effects
of Federal regulatory actions on State,
local, and Tribal governments and the
private sector. Public Law 104–4, sec.
201 (codified at 2 U.S.C. 1531). For a
proposed regulatory action likely to
result in a rule that may cause the
expenditure by State, local, and Tribal
governments, in the aggregate, or by the
private sector of $100 million or more
in any one year (adjusted annually for
inflation), section 202 of UMRA requires
a Federal agency to publish a written
statement that estimates the resulting
costs, benefits, and other effects on the
national economy. (2 U.S.C. 1532(a), (b))
The UMRA also requires a Federal
agency to develop an effective process
to permit timely input by elected
officers of State, local, and Tribal
governments on a proposed ‘‘significant
intergovernmental mandate,’’ and
requires an agency plan for giving notice
and opportunity for timely input to
potentially affected small governments
before establishing any requirements
that might significantly or uniquely
affect small governments. On March 18,
1997, DOE published a statement of
policy on its process for
PO 00000
Frm 00012
Fmt 4701
Sfmt 4702
intergovernmental consultation under
UMRA. 62 FR 12820; also available at
https://energy.gov/gc/office-generalcounsel. DOE examined today’s
proposed rule according to UMRA and
its statement of policy and determined
that the proposal contains neither an
intergovernmental mandate, nor a
mandate that may result in the
expenditure of $100 million or more in
any year, so these requirements do not
apply.
H. Review Under the Treasury and
General Government Appropriations
Act, 1999
Section 654 of the Treasury and
General Government Appropriations
Act, 1999 (Pub. L. 105–277) requires
Federal agencies to issue a Family
Policymaking Assessment for any rule
that may affect family well-being. This
rule would not have any impact on the
autonomy or integrity of the family as
an institution. Accordingly, DOE has
concluded that it is not necessary to
prepare a Family Policymaking
Assessment.
I. Review Under Executive Order 12630
DOE has determined, under Executive
Order 12630, ‘‘Governmental Actions
and Interference with Constitutionally
Protected Property Rights’’ 53 FR 8859
(March 18, 1988), that this regulation
would not result in any takings that
might require compensation under the
Fifth Amendment to the U.S.
Constitution.
J. Review Under Treasury and General
Government Appropriations Act, 2001
Section 515 of the Treasury and
General Government Appropriations
Act, 2001 (44 U.S.C. 3516 note) provides
for agencies to review most
disseminations of information to the
public under guidelines established by
each agency pursuant to general
guidelines issued by OMB. OMB’s
guidelines were published at 67 FR
8452 (Feb. 22, 2002), and DOE’s
guidelines were published at 67 FR
62446 (Oct. 7, 2002). DOE has reviewed
today’s proposed rule under the OMB
and DOE guidelines and has concluded
that it is consistent with applicable
policies in those guidelines.
K. Review Under Executive Order 13211
Executive Order 13211, ‘‘Actions
Concerning Regulations That
Significantly Affect Energy Supply,
Distribution, or Use,’’ 66 FR 28355 (May
22, 2001), requires Federal agencies to
prepare and submit to OMB, a
Statement of Energy Effects for any
proposed significant energy action. A
‘‘significant energy action’’ is defined as
E:\FR\FM\25APP2.SGM
25APP2
Federal Register / Vol. 79, No. 80 / Friday, April 25, 2014 / Proposed Rules
any action by an agency that
promulgated or is expected to lead to
promulgation of a final rule, and that:
(1) Is a significant regulatory action
under Executive Order 12866, or any
successor order; and (2) is likely to have
a significant adverse effect on the
supply, distribution, or use of energy; or
(3) is designated by the Administrator of
OIRA as a significant energy action. For
any proposed significant energy action,
the agency must give a detailed
statement of any adverse effects on
energy supply, distribution, or use
should the proposal be implemented,
and of reasonable alternatives to the
action and their expected benefits on
energy supply, distribution, and use.
Today’s regulatory action to amend
the test procedure for measuring the
energy efficiency of residential clothes
washers is not a significant regulatory
action under Executive Order 12866.
Moreover, it would not have a
significant adverse effect on the supply,
distribution, or use of energy, nor has it
been designated as a significant energy
action by the Administrator of OIRA.
Therefore, it is not a significant energy
action, and, accordingly, DOE has not
prepared a Statement of Energy Effects.
L. Review Under Section 32 of the
Federal Energy Administration Act of
1974
mstockstill on DSK4VPTVN1PROD with PROPOSALS2
Under section 301 of the Department
of Energy Organization Act (Pub. L. 95–
91; 42 U.S.C. 7101), DOE must comply
with section 32 of the Federal Energy
Administration Act of 1974, as amended
by the Federal Energy Administration
Authorization Act of 1977. (15 U.S.C.
788; FEAA) Section 32 essentially
provides in relevant part that, where a
proposed rule authorizes or requires use
of commercial standards, the notice of
proposed rulemaking must inform the
public of the use and background of
such standards. In addition, section
32(c) requires DOE to consult with the
Attorney General and the Chairman of
the Federal Trade Commission (FTC)
concerning the impact of the
commercial or industry standards on
competition. DOE is not requiring the
use of any new commercial standards in
this rulemaking, so these requirements
do not apply.

It is DOE’s policy that all comments
may be included in the public docket,
without change and as received,
including any personal information
provided in the comments (except
information deemed to be exempt from
public disclosure).
B. Issues on Which DOE Seeks Comment
Although DOE welcomes comments
on any aspect of this proposal, DOE is
particularly interested in receiving
comments and views of interested
parties concerning the following issues:
(1) The normal cycle definition and
whether it adequately covers the cycle
setting most commonly chosen by users
of washing machines;
(2) The potential test burden
associated with maintaining a tolerance
of five degrees on the hot and cold water
supply temperature ranges for clothes
washers in which electrical energy and
water energy consumption are affected
by the inlet water temperature;
(3) The potential increase in test
burden associated with removing the
separate testing provisions for clothes
washers with uniformly distributed
warm wash temperatures.
(4) Whether any discrepancies exist
when determining the wash/rinse
temperature selections comprising the
energy test cycle in appendix J2 using
the proposed flowcharts compared to
using the current energy test cycle
definition (and, if so, specific examples
of cycle setting configurations that
would lead to the discrepancies); and
(5) Whether the methodology
presented in the energy test cycle
flowcharts in appendix J2 could result
in an efficiency rating unrepresentative
of how a particular clothes washer
would be used by consumers.

maximum, minimum, and average water
levels as described in the following sections
refer to the amount of water fill that is
automatically selected by the control system
when the respective test loads are used.
3.2.6.2.2 User adjustable. Conduct four
tests on clothes washers with user adjustable
automatic water fill controls that affect the
relative wash water levels. Conduct the first
test using the maximum test load and with
the automatic water fill control system set in
the setting that will give the most energy
intensive result. Conduct the second test
using the minimum test load and with the
automatic water fill control system set in the
setting that will give the least energy
intensive result. Conduct the third test using
the average test load and with the automatic
water fill control system set in the setting
that will give the most energy intensive result
for the given test load. Conduct the fourth
test using the average test load and with the
automatic water fill control system set in the
setting that will give the least energy
intensive result for the given test load.
Average the results of the third and fourth
tests to obtain the energy and water
consumption values for the average test load
size.
3.2.6.3 Clothes washers with automatic
water fill control system and alternate
manual water fill control system. If a clothes
washer with an automatic water fill control
system allows user selection of manual
controls as an alternative, test both manual
and automatic modes and, for each mode,
calculate the energy consumption (HET, MET,
and DE) and water consumption (QT) values
as set forth in section 4 of this appendix.
Then, calculate the average of the two values
(one from each mode, automatic and manual)
for each variable (HET, MET, DE, and QT) and

6. Waivers and Field Testing
6.1 Waivers and Field Testing for
Nonconventional Clothes Washers.
Manufacturers of nonconventional clothes
washers, such as clothes washers with
adaptive control systems, must submit a
petition for waiver pursuant to 10 CFR
430.27 to establish an acceptable test
procedure for that clothes washer if the
washer cannot be tested pursuant to the DOE
VerDate Mar<15>2010

Jkt 232001
test procedure or the DOE test procedure
yields results that are so unrepresentative of
the clothes washer’s true energy
consumption characteristics as to provide
materially inaccurate comparative data. In
such cases, field testing may be appropriate
for establishing an acceptable test procedure.
The following are guidelines for field testing
that may be used by manufacturers in
support of petitions for waiver. These
PO 00000

Fmt 4701
Sfmt 4702
guidelines are not mandatory and the
Department may determine that they do not
apply to a particular model. Depending upon
a manufacturer’s approach for conducting
field testing, additional data may be required.
Manufacturers are encouraged to
communicate with the Department prior to
the commencement of field tests that may be
used to support a petition for waiver. Section
6.3 of this appendix provides an example of
E:\FR\FM\25APP2.SGM
25APP2

Federal Register / Vol. 79, No. 80 / Friday, April 25, 2014 / Proposed Rules
field testing for a clothes washer with an
adaptive water fill control system. Other
features, such as the use of various spin
speed selections, could be the subject of field
tests.
6.2 Nonconventional Wash System
Energy Consumption Test. The field test may
consist of a minimum of 10 of the
nonconventional clothes washers (‘‘test
clothes washers’’) and 10 clothes washers
already being distributed in commerce (‘‘base
clothes washers’’). The tests should include
a minimum of 50 wash cycles per clothes
washer. The test clothes washers and base
clothes washers should be identical in
construction except for the controls or
systems being tested. Equal numbers of both
the test clothes washer and the base clothes
washer should be tested simultaneously in
comparable settings to minimize seasonal or
end-user laundering conditions or variations.
The clothes washers should be monitored in
such a way as to accurately record the
average total energy and water consumption
per cycle, including water heating energy
when electrically heated water is used, and
the energy required to remove the remaining
moisture of the test load. Standby and off
mode energy consumption should be
measured according to section 4.4 of this test
procedure. The field test results should be
used to determine the best method to
correlate the rating of the test clothes washer
to the rating of the base clothes washer.
6.3 Adaptive water fill control system
field test. (1) Section 3.2.6.3 of this appendix
defines the test method for measuring energy
consumption for clothes washers that
incorporate both adaptive (automatic) and
alternate manual water fill control systems.
Energy consumption calculated by the
method defined in section 3.2.6.3 of this
appendix assumes the adaptive cycle will be
used 50 percent of the time. This section can
be used to develop field test data in support
of a petition for waiver when it is believed
that the adaptive cycle will be used more
than 50 percent of the time. The field test
sample size should be a minimum of 10 test
clothes washers. The test clothes washers
should be representative of the design,
construction, and control system that will be
placed in commerce. The duration of field
testing in the user’s house should be a
minimum of 50 wash cycles, for each unit.
No special instructions as to cycle selection
or product usage should be given to the field
test participants, other than inclusion of the
product literature pack that would be
shipped with all units, and instructions
regarding filling out data collection forms,
use of data collection equipment, or basic
procedural methods. Prior to the test clothes
washers being installed in the field test
locations, baseline data should be developed
for all field test units by conducting
laboratory tests as defined by section 1
through section 5 of this appendix to
determine the energy consumption, water
consumption, and remaining moisture
content values. The following data should be
measured and recorded for each wash load
during the test period: wash cycle selected,
the mode of the clothes washer (adaptive or
manual), clothes load dry weight (measured
after the clothes washer and clothes dryer
cycles are completed) in pounds, and type of
articles in the clothes load (e.g., cottons,
linens, permanent press). The wash cycles
used in calculating the in-home percentage
split between adaptive and manual cycle
usage should be only those wash cycles that
conform to the definition of the energy test
cycle.
Calculate:
T = The total number of wash cycles run
during the field test.
Ta = The total number of adaptive control
wash cycles.
Tm = The total number of manual control
wash cycles.
The percentage weighting factors:
Pa = (Ta/T) × 100% (the percentage weighting
for adaptive control selection)
Pm = (Tm/T) × 100% (the percentage
weighting for manual control selection)
(2) Energy consumption (HET, MET, and
DE) and water consumption (QT) values
calculated in section 4 of this appendix for
the manual and adaptive modes should be
combined using Pa and Pm as the weighting
factors.

approved lot of energy test cloth. These can
be accessed through DOE’s Web page for
standards and test procedures for residential
clothes washers at DOE’s Building
Technologies Office Appliance and
Equipment Standards Web site.
8. Add a new Appendix J3 to subpart
B of part 430 to read as follows:
3. Testing Conditions
■
Appendix J3 to Subpart B of Part 430–
Uniform Test Method for Measuring the
Moisture Absorption and Retention
Characteristics of New Energy Test
Cloth Lots
Note: DOE maintains an historical record
of the standard extractor test data and final
1. Objective
The following procedure is used to
evaluate the moisture absorption and
retention characteristics of a new lot of test
cloth by measuring the remaining moisture
content (RMC) in a standard extractor at a
specified set of conditions. The results are
used to develop a set of coefficients that
correlate the measured RMC values of the
new test cloth lot with a set of standard RMC
values established as an historical reference
point. These correction coefficients are
applied to the RMC measurements performed
during testing according to appendix J1 or
appendix J2 to 10 CFR 430 subpart B,
ensuring that the final corrected RMC
measurement for a clothes washer remains
independent of the test cloth lot used for
testing.
2. Definitions
2.1 AHAM means the Association of
Home Appliance Manufacturers.
2.2 Bone-dry means a condition of a load
of test cloth that has been dried in a dryer
at maximum temperature for a minimum of
10 minutes, removed and weighed before
cool down, and then dried again for 10
minute periods until the final weight change
of the load is 1 percent or less.
2.3 Lot means a quantity of cloth that has
been manufactured with the same batches of
cotton and polyester during one continuous
process.
3.1 Table 3.1 of this appendix provides
the matrix of test conditions. In the table, ‘‘g
Force’’ represents units of gravitational
acceleration. When this matrix is repeated 3
times, a total of 60 extractor RMC test runs
are required. For the purpose of the extractor
RMC test, the test cloths may be used for up
to 60 test runs (after preconditioning as
specified in appendix J1 or appendix J2).

3.3 Bone dryer temperature. The dryer
used for bone drying must heat the test cloth
and energy stuffer cloths above 210 °F (99
°C).
4. Test Loads
4.1 Preconditioning. New test cloths,
including energy test cloths and energy
stuffer cloths, must be pre-conditioned in a
clothes washer in the following manner:
Perform five complete wash-rinse-spin
cycles, the first two with current AHAM
Standard detergent Formula 3 and the last
three without detergent. Place the test cloth
in a clothes washer set at the maximum water
level. Wash the load for ten minutes in soft
water (17 ppm hardness or less) using 27.0
grams + 4.0 grams per pound of cloth load
of AHAM Standard detergent Formula 3. The
wash temperature is to be controlled to
135 °F ±5 °F (57.2 °C ±2.8 °C) and the rinse
temperature is to be controlled to 60 °F ±5 °F
(15.6 °C ±2.8 °C). Repeat the cycle with
detergent and then repeat the cycle three
additional times without detergent, bone
drying the load between cycles (for a total of
five complete wash-rinse-spin cycles).
4.2 Test load composition. Test loads
must be comprised of randomly selected
cloth at the beginning, middle and end of a
lot.
4.3 Test load size. Use a test load size of
8.4 lbs. Two test loads may be used for
standard extractor RMC tests, with each load
used for half of the total number of required
tests.
5. Test Measurements
5.1 Dry the test cloth until it is ‘‘bonedry’’ according to the definition in section
2.2 of this appendix. Record the bone-dry
weight of the test load (WI).
5.2 Prepare the test load for soak by
grouping four test cloths into loose bundles.
Create the bundles by hanging four cloths
vertically from one corner and loosely
wrapping the test cloth onto itself to form the
bundle. Bundles should be wrapped loosely
to ensure consistency of water extraction.
Then place the bundles into the water to
soak. Eight to nine bundles will be formed
depending on the test load. The ninth bundle
may not equal four cloths but can incorporate
energy stuffer cloths to help offset the size
difference.
5.3 Soak the test load for 20 minutes in
10 gallons of soft (<17 ppm) water. The entire
test load must be submerged. Maintain a
water temperature of 100 °F ± 5 °F (37.8 °C
± 2.8 °C) at all times between the start and
end of the soak.
5.4 Remove the test load and allow each
of the test cloth bundles to drain over the
water bath for a maximum of 5 seconds.
5.5 Manually place the test cloth bundles
in the basket of the extractor, distributing
them evenly by eye. The draining and
loading process must take no longer than 1
minute. Spin the load at a fixed speed
corresponding to the intended centripetal
acceleration level (measured in units of the
acceleration of gravity, g) ± 1g for the
intended time period ± 5 seconds. Begin the
timer when the extractor meets the required
spin speed for each test.
5.6 Record the weight of the test load
immediately after the completion of the
extractor spin cycle (WC).
5.7 Calculate the remaining moisture
content of the test load as (WC–WI)/WI.
5.8 Draining the soak tub is not necessary
if the water bath is corrected for water level
and temperature before the next extraction.
5.9 Drying the test load in between
extraction runs is not necessary. However,
the bone dry weight must be checked after
every 12 extraction runs to make sure the
bone dry weight is within tolerance (8.4 ± 0.1
lb).
5.10 The test load must be soaked and
extracted once following bone drying, before
continuing with the remaining extraction
runs. Perform this extraction at the same spin
speed used for the extraction run prior to
bone drying, for a time period of 4 minutes.
Either warm or cold soak temperature may be
used.
5.11 Measure the remaining moisture
content of the test load at five g levels: 100
g, 200 g, 350 g, 500 g, and 650 g, using two
different spin times at each g level: 4 minutes
and 15 minutes.
5.12 Repeat sections 5.1 through 5.11 of
this appendix using soft (<17 ppm) water at
60 °F ± 5 °F (15.6 °C ± 2.8 °C).
6. Calculation of RMC Correction Curve
6.1 Average the values of 3 test runs, and
fill in Table 3.1 of this appendix. Perform a
linear least-squares fit to determine
coefficients A and B such that the standard
RMC values shown in Table 6.1 of this
appendix (RMCstandard) are linearly related to
the RMC values measured in section 5 of this
appendix (RMCcloth):
RMCstandard ∼ A * RMCcloth + B
Where A and B are coefficients of the
linear least-squares fit.

I. Background
Title III of the Energy Policy and Conservation Act of 1975 (42
U.S.C. 6291, et seq.; ``EPCA'') sets forth a variety of provisions
designed to improve energy efficiency. (All references to EPCA refer to
the statute as amended through the American Energy Manufacturing
Technical Corrections Act (AEMTCA), Public Law 112-210 (Dec. 18,
2012)). Part B of title III, which for editorial reasons was
redesignated as Part A upon incorporation into the U.S. Code (42 U.S.C.
6291-6309, as codified), establishes the ``Energy Conservation Program
for Consumer Products Other Than Automobiles.'' These include
residential clothes washers, the subject of today's notice. (42 U.S.C.
6292(a)(7))
Under EPCA, the energy conservation program consists essentially of
four parts: (1) Testing, (2) labeling, (3) Federal energy conservation
standards,
[[Page 23063]]
and (4) certification and enforcement procedures. The testing
requirements consist of test procedures that manufacturers of covered
products must use as the basis for (1) certifying to DOE that their
products comply with the applicable energy conservation standards
adopted under EPCA, and (2) making representations about the efficiency
of those products. Similarly, DOE must use these test procedures to
determine whether the products comply with any relevant standards
promulgated under EPCA.
General Test Procedure Rulemaking Process
Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures
DOE must follow when prescribing or amending test procedures for
covered products. EPCA provides in relevant part that any test
procedures prescribed or amended under this section shall be reasonably
designed to produce test results that measure energy efficiency, energy
use, or estimated annual operating cost of a covered product during a
representative average use cycle or period of use and shall not be
unduly burdensome to conduct. (42 U.S.C. 6293(b)(3))
In addition, if DOE determines that a test procedure amendment is
warranted, it must publish proposed test procedures and afford the
public an opportunity to present oral and written comments on them. (42
U.S.C. 6293(b)(2)) Finally, in any rulemaking to amend a test
procedure, DOE must determine to what extent, if any, the proposed test
procedure would alter the measured energy efficiency of any covered
product as determined under the existing test procedure. (42 U.S.C.
6293(e))
DOE test procedures for clothes washers are codified at appendices
J1 and J2 to 10 CFR part 430 subpart B (hereafter, ``appendix J1'' and
``appendix J2''). DOE most recently amended the test procedures for
clothes washers on March 7, 2012 (hereafter, the ``March 2012 final
rule''). 77 FR 13888. The March 2012 final rule amended certain
provisions in appendix J1 and also established the clothes washer test
procedure codified in appendix J2.
Manufacturers of residential clothes washers are required to make
representations of energy efficiency using either appendix J1 or
appendix J2, as revised by the March 2012 final rule. Manufacturers
must use a single test procedure for all representations for a basic
model and may not use appendix J1 for certain representations and
appendix J2 for other representations. Compliance with DOE's amended
standards for residential clothes washers, and the corresponding
mandatory use of the test procedure at appendix J2 for all
representations, is required as of March 7, 2015. 77 FR 32308 (May 31,
2012) and 77 FR 59719 (October 1, 2012).
II. Summary of the Notice of Proposed Rulemaking
In this NOPR, DOE proposes clarifications and technical amendments
to its test procedures for clothes washers at appendix J1 and appendix
J2. In addition, DOE proposes amendments to the reporting and
verification requirements for residential clothes washers. DOE has
determined that today's proposed amendments, as described in section
III, would not alter the measured efficiency of clothes washers. The
proposed amendments either codify guidance interpreting DOE's existing
regulations, provide further clarification of the relevant test
procedure provisions, provide improved organization of each section, or
correct formatting errors in DOE's clothes washer test procedures.
III. Discussion
A. Clothes Container Capacity Measurement
1. Capacity Measurement in Appendix J1
Section 3.1 of appendix J1 contains procedures for measuring the
clothes container capacity. The capacity measurement procedure involves
filling the clothes container with water and determining the volume
based on the weight of the added water divided by the water density.
Section 3.1.4 specifies that the clothes container be filled manually
with water to its ``uppermost edge.''
DOE published guidance on July 6, 2010, clarifying the definition
of the uppermost edge of the clothes container for the purpose of
performing the capacity measurement. See DOE's guidance document at:
https://www1.eere.energy.gov/buildings/appliance_standards/pdfs/clotheswashers_faq1_2010-07-06.pdf.
The guidance document provides detailed descriptions and
illustrations of the boundary defining the uppermost edge of the
clothes container for both top-loading and front-loading clothes
washers. For top-loading vertical-axis clothes washers, DOE's guidance
document defines the uppermost edge of the clothes container as the
highest point of the innermost diameter of the tub cover. For front-
loading horizontal-axis clothes washers, the guidance document
specifies filling the clothes container with water to the highest point
of contact between the door and the door gasket. If any portion of the
door or the door gasket would occupy the measured volume when the door
is closed, that volume must be excluded from the measurement. DOE's
guidance document also provides illustrations of the boundary defining
the uppermost edge of the clothes container for both top-loading and
front-loading clothes washers. The proposed amendments incorporate
these clarifications into section 3.1.4 of appendix J1, including the
illustrations.
The proposal also further clarifies the appropriate water fill
levels for front-loading horizontal-axis clothes washers with concave
door shapes and top-loading horizontal-axis clothes washers. For front-
loading horizontal-axis clothes washers with concave door shapes, the
capacity measurement would include any space above the plane defined by
the highest point of contact between the door and the door gasket, if
that area can be occupied by clothing during washer operation.
Similarly, for top-loading hojjhrizontal-axis clothes washers, the
water fill volume would include any space above the plane of the door
hinge, if that area can be occupied by clothing during washer
operation. This additional clarification is consistent with the
illustrations for these clothes washer types provided in DOE's guidance
document.
2. Capacity Measurement in Appendix J2
Section 3.1.4 of appendix J2 specifies the maximum allowable water
fill levels for determining the capacity of top-loading and front-
loading clothes washers. For front-loading horizontal-axis clothes
washers, section 3.1.4 specifies filling the clothes container to the
``uppermost edge that is in contact with the door seal.'' DOE intended
this language to clarify the text in DOE's July 6, 2010 guidance
document interpreting appendix J1, but did not intend for the measured
capacity values to differ. Since publishing the March 2012 final rule,
DOE has become aware of front-loading clothes washer door geometries
with complex curvatures that may not have an easily discernible
``uppermost edge'' in contact with the door seal. Therefore, DOE
proposes to amend the description of the maximum fill volume for front-
loading clothes washers using the same language as the proposed
amendments in appendix J1 and specified in the July 6, 2010 guidance,
as described in the previous section. The proposed revision would
provide additional clarity by referencing the ``highest point of
contact'' rather than the ``uppermost edge,'' and will more
[[Page 23064]]
clearly identify the geometric boundary between the door and the door
gasket. The proposal would more clearly define the uppermost fill level
for a wider range of front-loading clothes washer geometries. As noted
above, DOE intends for the measured capacity of a front-loading clothes
washer using the proposed revised language to be equivalent to the
measured capacity using the current front-loading capacity language in
section 3.1.4 of appendix J2.
The proposed amendments to appendix J2 also incorporate
illustrations of the boundary defining the uppermost edge of the
clothes container for top-loading vertical-axis clothes washers and the
boundaries defining the fill volumes for horizontal-axis clothes
washers.
3. Capacity Rounding Requirements
In both appendix J1 and appendix J2, the capacity measurement is
used to determine the test load sizes as defined in Table 5.1. The
table provides test load sizes for capacity ranges in increments of
0.10 cubic feet. The precision of the capacity ranges in Table 5.1
implies that the capacity of the clothes container must be measured to
the nearest 0.01 cubic foot for the purpose of determining load size.
However, manufacturers typically report capacity to the nearest 0.1
cubic foot in DOE certification reports and in retail advertisements.
The proposed amendments clarify that, under appendix J1 and
appendix J2, capacity must be measured to the nearest 0.01 cubic foot
not only for the purpose of determining load size, but also for the
purpose of calculating the values that manufacturers must report
pursuant to 10 CFR 429.20(b). In both appendices, DOE proposes
specifying this requirement in a new section 3.1.7 following the
calculation of capacity in newly renumbered section 3.1.6.
The proposed amendments would also specify in a new section at 10
CFR 429.20(c) that capacity must be reported to the nearest 0.1 cubic
foot (cu. ft.) for the purpose of DOE certification reports for
residential clothes washers.
Finally, DOE proposes to clarify in a new section at 10 CFR
429.20(a)(3) that the certified capacity of any clothes washer basic
model shall be the mean of the capacities of the units in the sample
for the basic model. While DOE believes this is current practice
because the existing test procedure and sampling plan require testing
at least two units and measuring the drum capacity individually for
each, DOE is proposing this amendment for clarity.
4. Plastic Sheet Material
Section 3.1.2 of both appendix J1 and appendix J2 instructs the
testing party to line the inside of the clothes container with a 2 mil
thickness (0.051mm) plastic sheet in preparation for performing the
capacity measurement. DOE is aware that common industry practice is to
use a large 2 mil plastic bag, rather than a plastic sheet, for lining
the clothes container because the shape of the plastic bag more easily
conforms to the geometry of the clothing container. DOE believes the
measured capacity of the clothes washer would be the same regardless of
whether a plastic sheet or plastic bag is used, provided that the
thickness of either the plastic sheet or plastic bag is 2 mil. DOE
therefore proposes to amend section 3.1.2 of both appendix J1 and
appendix J2 to allow the use of either a 2 mil thickness plastic sheet
or plastic bag to line the inside of the clothes container.
5. Shipping Bolts
Typically, front-loading clothes washers are designed with large
bolts, inserted through the back of the clothes washer, that secure the
wash drum to prevent movement of the drum during shipping. These
``shipping bolts'' must be removed prior to operating the clothes
washer. Alternatively, on some front-loading clothes washers, the drum
is secured using other forms of bracing hardware that is intended to be
removed prior to operating the clothes washer.
Section 3.1.1 of appendix J2 currently specifies that the shipping
bolts must remain in place during the capacity measurement procedure to
support the wash drum and prevent it from sagging downward as the drum
is filled with water. The proposed amendments would add a reference to
``other forms of bracing hardware'' in section 3.1.1 of both appendix
J1 and appendix J2.
In addition, DOE has become aware of front-loading clothes washer
designs that do not use shipping bolts or other forms of bracing
hardware to support the wash drum during shipping. DOE proposes further
amending section 3.1.1 of both appendix J1 and J2 to describe how a
laboratory should measure the capacity of this type of clothes washer.
The proposed amendments would allow a laboratory to support the wash
drum by other means, including temporary bracing or support beams. Any
temporary bracing or support beams would be required to keep the wash
drum in a fixed position, relative to the geometry of the door and door
seal components, that is representative of the position of the wash
drum during normal operation. The proposal would also require that the
method used avoid damage to the unit that would affect the results of
the energy and water testing. The proposed amendments further specify
that the test report must fully document the method used to support the
wash drum, and pursuant to 10 CFR 429.71, the manufacturer must retain
such documentation as part of its test records.
B. Hot and Cold Water Supply Test Conditions
Section 2.3.1 of both appendix J1 and appendix J2 specifies that
the temperature of the hot water supply must not exceed 135 [deg]F and
the cold water supply must not exceed 60 [deg]F for clothes washers in
which electrical energy or water energy consumption are affected by the
inlet water temperature (for example, water heating clothes washers or
clothes washers with thermostatically controlled water valves). This
specification does not provide a lower bound for the hot and cold water
supply temperatures. In contrast, section 2.3.2 of both test procedures
specifies a hot water supply temperature of 135 [deg]F 5
[deg]F and a cold water supply temperature of 60 [deg]F 5
[deg]F for clothes washers in which electrical energy and water energy
consumption are not affected by the inlet water temperature.
On clothes washers with thermostatically controlled mixing valves,
the supply water temperatures directly affect the relative quantities
of hot and cold water consumption during a wash cycle. DOE has observed
that the large majority of residential clothes washers on the market
now use thermostatically controlled mixing valves or other similar
technologies for precisely controlling the wash water temperatures.
DOE's engineering analysis during the most recent energy conservation
standards rulemaking indicated that precise temperature control will be
required to achieve the higher efficiency levels established by the May
31, 2012 direct final rule. (77 FR 32308)
To improve consistency and repeatability of test results, DOE
proposes to establish a lower bound of 130 [deg]F for the hot water
supply and 55 [deg]F for the cold water supply for clothes washers in
which electrical energy or water energy consumption are affected by the
inlet water temperature. This would provide an allowable range of five
degrees on the hot and cold water supplies (i.e., 130-135 [deg]F and
55-60 [deg]F, respectively). This amendment would apply to both
appendix J1 and appendix J2 (with section 2.3.1 in appendix J2
renumbered to 2.2.1).
[[Page 23065]]
DOE notes that the proposed five-degree temperature tolerance is a
tighter tolerance than is required for clothes washers in which
electrical energy and water energy consumption are not affected by the
inlet water temperature; however, DOE notes that the water supply
temperature affects the outcome of the MEF results when testing clothes
washers with thermostatically controlled water valves more
significantly than for clothes washers without such valves. DOE
requests comment on the potential test burden associated with
maintaining a tolerance of five degrees on the hot and cold water
supply temperature for clothes washers in which electrical energy and
water energy consumption are affected by the inlet water temperature.
C. Test Cloth Standard Extractor RMC Test Procedure
Sections 2.6.5 through 2.6.7 of both appendix J1 and appendix J2
contain the procedures for performing the standard extractor remaining
moisture content (RMC) test to evaluate the moisture absorption and
retention characteristics and to develop a unique correction curve for
each new lot of test cloth. To improve the clarity and overall logical
flow of the test procedure, DOE proposes moving the contents of
sections 2.6.5 through 2.6.7 in both appendices to a new appendix J3 as
a standalone test method for measuring the moisture absorption and
retention characteristics of new energy test cloth lots.
D. Test Cloth Loading Instructions
Section 2.8.3 of both appendix J1 and appendix J2 instruct the
testing party to load the energy test cloths into the clothes washer by
grasping them in the center, shaking them to hang loosely, and then
``put them into the clothes container'' prior to activating the clothes
washer. DOE proposes to provide additional specificity for the test
cloth handling and loading instructions, which DOE believes will
improve the overall clarity and consistency of test cloth loading
procedures. The proposed amendments would apply to both appendix J1 and
appendix J2 (section 2.8.3 would be renumbered to 2.9.2 in appendix J2
per the proposed amendments).
DOE proposes using a modified version of the loading instructions
for towels and pillowcases provided in the Association of Home
Appliance Manufacturers (AHAM) HLW-1-2010 test method, Performance
Evaluation Procedures for Household Appliances.\1\ Like DOE's current
test cloth loading instructions, the AHAM procedure involves grasping
the towel/pillowcase in the center and shaking it so that it hangs
loosely. The AHAM procedure further describes placing the towels/
pillowcases into the drum with alternating orientations. It also
provides sketches illustrating each step in the loading process. DOE's
proposed amendments would adopt similar illustrations. The amendments
would also specify following any additional manufacturing loading
instructions provided to the user regarding the placement of clothing
within the clothing container.
---------------------------------------------------------------------------

---------------------------------------------------------------------------
E. Energy Test Cycle
1. Warm Rinse Cycles
Section 1.7 of appendix J1 defines the energy test cycle as (A) the
cycle recommended by the manufacturer for washing cotton or linen
clothes, including all wash/rinse temperature selections and water
levels offered in that cycle, and (B) for each other wash/rinse
temperature selection or water level available on that basic model, the
portion(s) of other cycle(s) with that temperature selection or water
level that, when tested pursuant to these test procedures, will
contribute to an accurate representation of the energy consumption of
the basic model as used by consumers.
DOE published guidance on September 21, 2010, clarifying that the
energy test cycle should include the warm rinse of the cycle most
comparable to the cottons and linens cycle if warm rinse is not
available on the cottons and linens cycle. See DOE's guidance document
at: https://www1.eere.energy.gov/buildings/appliance_standards/pdfs/clotheswasher_faq_2010-09-21.pdf. The proposed amendments codify
DOE's guidance by incorporating this clarification into section 1.7(B)
of appendix J1 (redesignated as section 1.8(B) due to the proposed
addition of a new entry in the list of definitions before the energy
test cycle definition).
As described in section III.E.4 of this NOPR, DOE is proposing a
new methodology for determining the energy test cycle in appendix J2.
Based on the proposed methodology, which is intended to improve clarity
without altering the cycle selections that will be part of the energy
test cycle, DOE has tentatively determined that a parallel
clarification regarding a warm rinse cycle is unnecessary in appendix
J2. The methodology for determining the warm wash/warm rinse
temperature selection in appendix J2 requires including the warm rinse
cycle if it is not available on the cycle recommended for washing
cotton or linen clothes but is available on an alternative cycle
selection.
2. Sanitization Cycles
As described in the previous section, the energy test cycle in
appendix J1 includes all temperature selections available on the cycle
recommended by the manufacturer for washing cotton or linen clothing.
The energy test cycle also includes other temperature selections
available on other cycles that ``will contribute to an accurate
representation of the energy consumption of the basic model as used by
consumers.''
Section 3.3 of appendix J1 defines the ``Extra Hot Wash'' as a
cycle with a maximum wash temperature of greater than 135[emsp14][deg]F
on water heating clothes washers. DOE is aware that on some clothes
washers, an extra hot temperature selection is available only on a
separate sanitization cycle. The proposed amendments to the energy test
cycle definition in appendix J1 would clarify that for such clothes
washers, the sanitization cycle should be included in the energy test
cycle if the cycle is recommended by the manufacturer for washing
clothing and if doing so would contribute to an accurate representation
of the energy consumption as used by consumers. If the extra hot
temperature selection is available only on a sanitization cycle not
recommended by the manufacturer for washing clothing (e.g., a cycle
intended only for sanitizing the wash drum), such a cycle would not be
required for consideration as part of the energy test cycle.
Based on DOE's proposed new methodology for determining the energy
test cycle in appendix J2, DOE has tentatively determined that a
specific clarification regarding a sanitization cycle is unnecessary in
appendix J2 because the methodology for determining the extra hot wash
temperature selection requires including the extra hot wash temperature
setting if such a setting is available on the clothes washer and is
recommended by the manufacturer for washing clothing.
3. Default Cycle Settings
Testing a clothes washer according to appendix J1 or appendix J2
requires selecting specific wash/rinse temperatures and wash water fill
levels for the wash cycles used to determine energy and water
consumption. In addition, specific spin speeds must be
[[Page 23066]]
selected for the wash cycle(s) used to determine the remaining moisture
content. Other than these settings, the test procedure does not
instruct the user to change any other optional settings during testing.
The proposed amendments to appendix J1 would modify section 1.7(B)
(redesignated as 1.8(B)) to clarify the requirement to use the
manufacturer default settings for any cycle selections, except for (1)
the temperature selection, (2) the wash water fill levels, or (3) if
necessary, the spin speeds on wash cycles used to determine remaining
moisture content. Specifically, the manufacturer default settings must
be used for wash conditions such as agitation/tumble operation, soil
level, spin speed on wash cycles used to determine energy and water
consumption, wash times, rinse times, optional rinse settings, water
heating time for water-heating clothes washers, and all other wash
parameters or optional features applicable to that wash cycle. Any
optional wash cycle feature (other than wash/rinse temperature, water
fill level selection, or spin speed on cycle selections used to
determine remaining moisture content) that is activated by default on
the wash cycle under test must be included for testing unless the
manufacturer instructions recommend not selecting this option for
washing normally soiled cotton or linen clothes.
The proposed amendments to appendix J2 would add a new section
3.2.7 to address the use of default cycle settings in the same manner
as the modification proposed for appendix J1. DOE believes the new
section 3.2.7 is the most appropriate location for this amendment in
appendix J2 in conjunction with the revised structure of the energy
test cycle definition and flowcharts in appendix J2.
4. Energy Test Cycle Definition and Flowcharts
DOE notes that appendix J1 uses the term ``energy test cycle'' in
two different ways. In some instances, ``energy test cycle'' refers to
the complete set of wash/rinse temperature selections required for
testing. In other instances, ``energy test cycle'' refers to the single
wash cycle under test. DOE does not propose changing its usage of the
term ``energy test cycle'' in appendix J1. In each instance where the
term ``energy test cycle'' is used, the specific meaning of the term
can be determined through context.
In appendix J2, however, DOE proposes to simplify the definition of
the energy test cycle so that it means the complete set of wash/rinse
temperature selections required for testing. The individual wash/rinse
temperature selections required for testing would be determined using a
new methodology as described below. The provisions within parts (D) and
(E) of the current energy test cycle definition would be moved to
sections 3.2.7 and 3.2.8, respectively, which is a more appropriate
location within the test procedure. Additionally, throughout appendix
J2, DOE proposes to provide greater consistency in its usage of the
term ``energy test cycle,'' such that when used, it refers only to the
entire set of wash/rinse temperature selections required for testing.
In instances where the test procedure currently uses the term ``energy
test cycle'' to refer to an individual wash cycle, DOE proposes to use
the generic term ``wash cycle'' or other similar terminology as
appropriate for each instance. DOE also proposes to improve overall
clarity by providing the full wash/rinse temperature designation (e.g.
``Cold wash/Cold rinse'') throughout the test procedure.
In conjunction with the simplified energy test cycle definition,
DOE proposes a new approach to determining the wash/rinse temperature
selections required for testing in appendix J2. DOE proposes to
translate the current methodology for determining the energy test cycle
into a set of flowcharts that testing parties would use to determine
each wash/rinse temperature selection to be used for testing. DOE
believes that the binary nature of each decision box within the
flowcharts would provide increased clarity and ease of use in
determining which wash/rinse temperature settings to use for testing.
DOE proposes to include these flowcharts within newly renumbered
section 2.12 in appendix J2.
Because the proposed flowcharts would incorporate more precise
definitions of warm and cold rinse temperatures, DOE also proposes to
clarify the definition of ``cold rinse'' in appendix J2 so that it
means the coldest rinse temperature available on the machine, as
indicated to the user on the clothes washer control panel. This would
prevent the unintended consequence of a wash/rinse temperature
designation being excluded from the energy test cycle if the rinse
portion of the cycle included a small amount of hot water (thus raising
the rinse temperature slightly higher than the coldest rinse available
on the machine), but was indicated on the control panel as being a cold
rinse paired with the selected wash temperature.
In addition, DOE proposes adding a new definition in appendix J2
for ``Normal cycle,'' which would be defined as: ``Normal cycle means
the cycle selection recommended by the manufacturer as the most common
consumer cycle for washing a full load of normally to heavily soiled
cotton clothing. For machines where multiple cycle settings meet this
description, then the Normal cycle is the cycle selection that results
in the lowest IMEF or MEF value.'' ''. DOE first adopted a similar
definition of ``Normal cycle'' for clothes washer testing in appendix
J, which incorporated the general approach to calculating the energy
consumption of automatic clothes washers contained in AHAM's standard
HLW-2EC for clothes washers at the time. (42 FR 25329, 25330 (May 17,
1977); 42 FR 49802 (September 28, 1977)) Over time, machine labeling
and literature evolved to the point that the term ``normal'' as
previously defined no longer captured all of the control settings most
consumers would typically choose in operating the machine to wash their
laundry. (See, e.g., 75 FR 57556, 57575) Further, the range of cycle
options and terminology on the control panels have changed such that
many machines no longer refer to a ``Normal'' cycle, instead relying
upon other terms. This evolution may have resulted in inaccurate
representations of the energy usage of these machines due to differing
interpretations regarding the appropriate test cycle. In order to add
clarity and ensure consistent selection of the appropriate cycle for
energy testing, DOE is proposing to add the ``Normal cycle'' definition
in newly designated section 1.25 and to reference the term in the new
energy test cycle flowcharts, and DOE will consider manufacturer
literature and markings on the machine when determining the normal
cycle of any particular unit. DOE specifically seeks comment on this
definition and whether it adequately covers the cycle setting most
commonly chosen by users of washing machines.
DOE also proposes to remove the definitions for ``warm rinse'' and
``warm wash'' from section 1 of appendix J2 (Definitions and Symbols),
since those terms would be defined in the proposed flowcharts instead.
Finally, DOE proposes to move the current section 2.13 of appendix
J2, Energy consumption for the purpose of certifying the cycle
selection(s) to be included in Part (B) of the energy test cycle
definition, to newly created section 3.10. Section 3 of appendix J2
(Test Measurements), is a more appropriate location in the test
procedure for these provisions.
[[Page 23067]]
DOE intends for the cycle selections as determined using the new
energy test cycle flowcharts to be the same as the cycle selections as
determined using the current energy test cycle definition in appendix
J2. DOE requests comment on whether discrepancies exist when
determining the wash/rinse temperature selections using the proposed
flowcharts compared to using the current energy test cycle definition.
If discrepancies exist, DOE requests that interested parties provide
specific examples of cycle setting configurations that would lead to
the discrepancies. DOE also requests comment on whether the methodology
presented in the flowcharts could result in an efficiency rating that
is unrepresentative of how a particular clothes washer would be used by
consumers.
F. Wash Time Setting
DOE proposes moving the wash time setting provisions from section
2.10 of appendix J2 to a subsection of newly revised section 3.2.5. The
procedure for setting the wash time must be performed prior to each
individual wash cycle during testing; therefore, the most appropriate
location for this instruction is within the specific testing procedures
provided in section 3.2.
G. Standby and Off Mode Testing
DOE proposes clarifications to the standby and off mode power
testing provisions in appendix J2. In addition to minor wording
clarifications in sections 3.9 and 3.9.1 of appendix J2, the proposed
clarifications are as follows:
1. Testing Sequence
DOE proposes clarifying that combined low-power mode testing in
section 3.9 of appendix J2 be performed after completion of an energy
test cycle, after removing the test load, and without disconnecting the
electrical energy supply to the clothes washer between completion of
the energy test cycle and the start of combined low-power mode testing.
This clarification would preclude performing combined low-power mode
testing directly after connecting the clothes washer to the electrical
energy supply. DOE testing suggests that testing a clothes washer's
standby or off-mode power consumption directly after connecting the
clothes washer to the electrical energy supply may not be
representative of the standby or off-mode power consumption after its
first use. DOE believes this clarification would ensure that the
results of the combined low-power mode testing accurately represent the
conditions most likely to be experienced in a residential setting.
2. Default Settings
DOE proposes clarifying that combined low-power mode testing be
performed without changing the control panel settings used for the
energy test cycle completed prior to combined low-power mode testing.
The test procedure requires using the manufacturer default settings for
any wash cycle performed within the energy test cycle. The proposed
clarification would preclude activating or deactivating any optional
control panel displays or other features not activated by default on
the clothes washer when it is not being used to perform an active mode
wash cycle, during combined low-power mode testing. DOE believes this
clarification would ensure that the results of the combined low-power
mode testing accurately represent the conditions most likely to be
experienced in a residential setting.
3. Multiple Possible Inactive Modes
DOE testing indicates that some residential appliances, including
clothes washers, may have multiple modes that meet the definition of
inactive mode currently provided in section 1.15 of appendix J2
(redesignated section 1.16). DOE proposes clarifying that inactive mode
is the lowest-power standby mode that facilitates the activation of
active mode by remote switch (including remote control), internal
sensor, or timer, or that provides continuous status display.
Specifying use of the lowest-power mode would clarify potential
ambiguity regarding which inactive mode to use for testing if multiple
inactive modes exist on a clothes washer.
H. Fixed Water Fill Control Systems
The load sizes used for testing depend upon the type of water fill
control system available on the clothes washer, as defined in section
2.8 of both appendix J1 and appendix J2. For clothes washers with
manual water fill control systems, the minimum and maximum load sizes
are tested. For clothes washers with adaptive water fill control
systems, the minimum, average, and maximum load sizes are tested.
DOE has become aware of clothes washers that have fixed water
levels for all load sizes and no water fill selector or water fill
control settings available to the user. DOE notes that, as with
adaptive water fill control systems, fixed water fill control systems
do not require user action to determine the water fill level.
Therefore, DOE proposes that a clothes washer with a fixed water fill
control system be tested in the same manner as a clothes washer with an
adaptive water fill control system; i.e., using the minimum, average,
and maximum load sizes.
The proposed amendments would (1) add a definition for ``fixed
water fill control system,'' (2) add a definition for ``automatic water
fill control system,'' which would include both fixed water fill
control systems and adaptive water fill control systems, and (3) amend
the definition of ``adaptive water fill control system'' to clarify
that it is considered a type of automatic water fill control system.
Additionally, where appropriate, instances of ``adaptive water fill
control system'' throughout the test procedure would be replaced with
``automatic water fill control system,'' to indicate that such testing
provisions apply to both adaptive water fill control systems and fixed
water fill control systems. These amendments would apply to both
appendix J1 and appendix J2.
I. Deep Rinse and Spray Rinse Definitions
Section 3.2.2 of appendix J2 states that total water consumption
during the energy test cycle shall be measured, including hot and cold
water consumption, during wash, deep rinse, and spray rinse. As
proposed, the revised section 3.2.8 would specify including the entire
active washing mode, and excluding any delay start or cycle finished
modes, for each wash cycle tested. Active washing mode is defined in
section 1.2 as including the main functions of washing, soaking,
tumbling, agitating, rinsing, and/or removing water from the clothing.
DOE believes that the proposed revision to 3.2.8 provides better
clarity and completeness, compared to the wording in 3.2.2, regarding
the portions of the wash cycle to be included and measured for testing.
Therefore, DOE proposes to delete section 3.2.2 from appendix J2 and to
renumber the subsequent subsections accordingly.
Furthermore, since section 3.2.2 is the only location within the
test procedure where the terms ``deep rinse'' and ``spray rinse''
occur, DOE also proposes to remove those two definitions from the
section 1 of appendix J2.
J. Uniformly Distributed Warm Wash Temperatures
Section 1.17 of appendix J1 and section 1.32 of appendix J2 provide
the definition of uniformly distributed warm wash temperature
selections. A clothes washer has uniformly distributed warm wash
temperature selections if (A) the warm wash temperatures have a linear
relationship with all discrete warm wash selections
[[Page 23068]]
when the water temperatures are plotted against equally spaced
consecutive warm wash selections between the hottest warm wash and the
coldest warm wash, and the mean water temperature of the warmest and
the coldest warm selections coincide with the mean of the hot wash and
cold wash water temperatures within 3.8[emsp14][deg]F; or
(B) on a clothes washer with only one warm wash temperature selection,
the warm wash temperature selection has a water temperature that
coincides with the mean of the hot wash and cold wash water
temperatures within 3.8[emsp14][deg]F. For clothes washers
with uniformly distributed warm wash temperature selections, the
reported values to be used for the warm wash setting are the arithmetic
average of the measurements for the hot and cold wash selections. This
is a ``shortcut'' calculation only; no testing is required.
DOE notes that the criteria for determining whether the warm wash
temperatures are uniformly distributed are based on water temperature
only; total water consumption is not considered. On a clothes washer
with electronic control systems, a clothes washer's warm wash cycles
could be programmed to use larger quantities of water than the cold
wash and hot wash cycles, yet the data to be used to represent the warm
wash cycle would be the average of the cold and hot wash cycles, rather
than actual data from testing. Since the warm wash temperature
selection has the highest temperature use factor at 0.49, DOE proposes
that the warm wash temperature selection(s) on such a clothes washer be
tested. Therefore, DOE proposes to remove the definition of uniformly
distributed warm wash temperature selections from both appendix J1 and
appendix J2, and to remove any provisions within the test procedures
pertaining to uniformly distributed warm wash temperature selections.
DOE requests comment on any potential increase in test burden as
result of its proposal to eliminate the separate testing provisions for
clothes washers with uniformly distributed warm wash temperatures. DOE
estimates that the resulting total testing time would be no greater
than for clothes washers with the same number of warm wash temperature
options, but with non-uniformly distributed temperatures, which DOE
observes constitutes the majority of the market.
K. Determining Extra Hot Wash Temperature
Section 3.3 of both appendix J1 and appendix J2 defines Extra Hot
Wash as having a maximum wash temperature greater than
135[emsp14][deg]F. Determining the maximum wash temperature requires
measuring the water temperature during the wash cycle to determine the
maximum wash temperature achieved. DOE understands that, in practice,
measuring the wash water temperature can be difficult due to factors
such as the geometry of front-loading tub design; the increasing use of
door locks; and, in high-efficiency clothes washers, the lack of a
standing pool of wash water from which to measure the temperature.
DOE proposes adding a statement to section 3.3 of both appendix J1
and appendix J2 to provide guidance on one possible method that testing
parties could use to determine the maximum wash water temperature. In
the proposed method, testing parties would adhere non-reversible
temperature indicator labels to the inside of the clothing container to
determine the maximum water temperature during an energy test cycle. If
a testing party used the temperature indicator label method when
testing a front-loading clothes washer, the label would be adhered
along the inner circumference of the clothes container drum, midway
between the front and the back of the clothes container. For a top-
loading clothes washer, the label would be adhered along the inner
circumference of the clothes container drum, as close to the bottom of
the container as possible.
Manufacturers may be able to use alternate methods for determining
the maximum wash temperature during an energy test cycle; however, DOE
is unaware of any other direct measurement methods that could be safely
used by a third-party laboratory without requiring partial disassembly
of the clothes washer or without permanently altering the machine.
L. Gas-Heated and Oil-Heated Hot Water Energy
Section 4.1.4 of both appendix J1 and appendix J2 provides
equations for calculating per-cycle hot water energy consumption using
gas-heated or oil-heated water. The result of this calculation is not
used in any downstream calculations within the test procedure. The
calculated result is referenced within 10 CFR 430.23(j)(1)(i)(B) and
(ii)(B); however, these values are not included as part of DOE's
certification requirements for clothes washers in 10 CFR 429.20 and
429.46, nor are they required for other DOE regulatory purposes. DOE is
unaware of any other regulatory programs that require the calculation
of per-cycle hot water energy using gas- or oil-heated water for
clothes washers. Therefore, DOE proposes to remove section 4.1.4 from
both appendix J1 and appendix J2, and to remove the related sections of
10 CFR 430.23(j)(1)(i)(B) and (ii)(B), adjusting the subsequent section
numberings accordingly.
M. Out-of-Balance Loads
DOE has observed that some clothes washers may terminate the wash
cycle prematurely if an out-of-balance condition is detected. Because
the test procedure defines an energy test cycle as including the
agitation/tumble operation, spin speed(s), wash times, and rinse times
applicable to each cycle, the data from a wash cycle that terminates
prematurely if an out-of-balance condition is detected, and thus does
not include these required elements, should be discarded. The proposed
amendments provide this clarification to section 3.2 of appendix J1 and
a new section 3.2.9 of appendix J2.
N. Reordering of Section 2, Testing Conditions
DOE proposes to reorder the subsections within section 2 of
appendix J2 (Testing Conditions) to improve the clarity and overall
flow of the section. After reordering, the general progression of
section 2 would be as follows:
Laboratory infrastructure requirements
Instrumentation requirements
Test cloth requirements
Test load composition and handling
Clothes washer installation and preconditioning procedures
Energy test cycle determination
O. Table 3.2 Edits
Table 3.2 in both appendix J1 and appendix J2 defines the sections
within the test procedure that govern the tests of particular clothes
washers, based on the number of wash/rinse temperature selections
available on the model. DOE proposes to clarify one of the headings in
Table 3.2 of appendix J1. The proposal would amend the current heading,
``Number of wash temp. selections'' to ``Number of wash temp.
selections in the energy test cycle.'' In addition, Table 3.2 in
appendix J1 contains a typographical error in the second footnote: the
word ``heating'' is misspelled. Today's proposal corrects this error.
DOE proposes simplifying the overall structure of Table 3.2 in
appendix J2 (renumbered 3.2.2) by using the clarified wash/rinse
temperature nomenclature within the revised energy
[[Page 23069]]
test cycle definition and flowcharts. DOE does not intend for any of
the required test sections to change as a result of the proposed
revisions to the table.
P. Table 4.1.1 Edits
Table 4.1.1 in appendix J2 provides the temperature use factors.
DOE proposes improving the clarity of the overall structure of Table
4.1.1 in appendix J2 by reorganizing the columns in the table to more
closely match the wash/rinse temperature nomenclature within the
revised energy test cycle definition and flowcharts. DOE does not
intend for any of the temperature use factors to change as a result of
the proposed revisions to the table.
Q. Table 2.8 Edits
In the March 2012 final rule, Table 2.8 in appendix J2 (``Test Load
Sizes and Water Fill Settings Required'') contained a formatting error
that combined the average and minimum test load sizes into a single row
for clothes washers with an adaptive water fill control system. DOE did
not intend to amend the test load sizes required for clothes washers
with an adaptive water fill control system. Today's proposal amends the
layout of Table 2.8 in both appendix J1 and appendix J2 to improve its
overall clarity. As described above, DOE has also proposed changing the
heading of the relevant column to ``automatic water fill control
system'' rather than ``adaptive water fill control system''.
R. Replacing ``Consumer'' With ``User''
Both appendix J1 and appendix J2 refer to the ``consumer'' in
various parts of the test procedures. In each instance, the word
``consumer'' refers to the individual using the clothes washer. DOE
notes that the word ``consumer'' may be misconstrued as the original
purchaser or owner of the clothes washer. In some cases, particularly
coin-operated laundries and multi-family housing common laundry rooms,
the purchaser or owner of the clothes washer is not the end user of the
clothes washer.
The distinction between the owner and the end user may be relevant
to the test procedure if certain settings, such as water fill levels,
may be customized by the owner of the clothes washer but are not
adjustable by the end user. To prevent any possible ambiguity implied
by the word ``consumer,'' DOE proposes to replace the word ``consumer''
with ``user'' or ``end user'' throughout the test procedure in all
instances where the word ``consumer'' is currently used.
S. Introductory Text
DOE proposes revising the introductory text after the appendix
headings in both appendix J1 and appendix J2 to clarify the proper use
of appendices J1 and J2 for making representations of energy
efficiency, including certifying compliance with DOE energy
conservation standards.
DOE test procedures for clothes washers are set forth in appendices
J1 and J2 in 10 CFR Part 430 subpart B. This proposal describes
amendments to both appendices. Pursuant to 42 U.S.C. 6293(c),
manufacturers must make representations of energy efficiency using any
amendments DOE adopts in a final test procedure rule beginning 180 days
after the effective date of such rule. Therefore, beginning 180 days
after the effective date of any final amendments based on today's
proposals, manufacturers must make representations of energy efficiency
pursuant to appendix J1 or appendix J2 as modified through such
amendments.
In addition, as of March 7, 2015, manufacturers of residential
clothes washers will no longer be authorized to use appendix J1.
Residential clothes washer manufacturers must use appendix J2, as
modified though any amendments that DOE may adopt based on today's
proposal, to demonstrate compliance with the standards and make any
representations of energy efficiency as of March 7, 2015. March 7, 2015
is the compliance date of the amended energy conservation standards
that address standby and off mode energy consumption for residential
clothes washers. 77 FR 32308 (May 31, 2012) and 77 FR 59719 (October 1,
2012).
T. Test Procedure Provisions in 10 CFR 430.23
DOE proposes revising section 430.23(j)(3) to contain only the
provisions for calculating annual water consumption when using either
appendix J1 or appendix J2. The proposed amendments would add a new
section 430.23(j)(4), which would contain the provisions for
determining water factor and integrated water factor.
The proposed amendments would also create a new section
430.23(j)(5) that would contain the following statement: ``Other useful
measures of energy consumption for automatic or semi-automatic clothes
washers shall be those measures of energy consumption that the
Secretary determines are likely to assist consumers in making
purchasing decisions and that are derived from the application of
appendix J1 or appendix J2, as appropriate.'' This statement is
currently contained in section 430.23(j)(3). Moving the statement to a
dedicated subsection would maintain consistency with DOE's test
procedure provisions for other products within 10 CFR Part 430. DOE
notes that the measurement or reporting of any additional measures of
energy or water consumption would be adopted through the rulemaking
process.
Finally, to eliminate any potential ambiguity, the proposed
amendments would replace the phrase ``can be determined'' with ``must
be determined'' throughout the text of 10 CFR 430.23(j)(3) through
(j)(5).
U. Reporting and Verification Requirements
1. Remaining Moisture Content
DOE has observed the potential for significant variation in the RMC
measurement at the maximum spin speed setting on some clothes washer
models. During testing of front-loading clothes washer models, DOE
observed that the maximum target spin speed may not be achieved during
the final spin portion of the cycle if the load size is not evenly
distributed around the circumference of the wash drum. DOE believes
that in such cases, the spin speed may be automatically reduced as a
safety precaution and to prevent damage to the clothes washer caused by
the asymmetric rotation of the unbalanced load within the wash basket.
Figure III.1 shows an example of RMC test data obtained from one
front-loading residential clothes washer model. DOE performed the RMC
measurement using the cold wash cycle at the maximum available spin
speed setting. The RMC measurement was performed a total of twelve
times using three different test cloth lots. The corrected RMC
measurement \2\ varied between 32.3 percent and 46.2 percent, with an
average of 37.0 percent. DOE has observed similar variations of this
magnitude on multiple front-loading clothes washer models.
---------------------------------------------------------------------------
\2\ Corrected RMC measurements are obtained using the test cloth
correction factors developed for each test cloth lot, as applied in
section 2.6.7 of appendix J1 and appendix J2. DOE publishes a list
of the test cloth correction factors developed for test cloth Lots 5
through 20 at https://www2.eere.energy.gov/buildings/appliance_standards/residential/clothes_washer_test_cloth_correction.html.
---------------------------------------------------------------------------
[[Page 23070]]
[GRAPHIC] [TIFF OMITTED] TP25AP14.014
The RMC measurement is used to determine the per-cycle energy
consumption for removal of moisture from the test load; i.e., the
``drying energy'' portion of the MEF and Integrated Modified Energy
Factor (IMEF) calculations. The drying energy represents between 59 and
87 percent of a clothes washer's total energy consumption; \3\ hence,
the RMC measurement significantly impacts the overall MEF and IMEF
calculations. For example, the level of RMC variation shown in Figure
III.1 would lead to a 25 percent variation in the overall MEF
calculation.
---------------------------------------------------------------------------
\3\ Percentages derived from Table 7.2.1 and 7.2.2 in the May
31, 2012 direct final rule technical support document for the
residential clothes washer energy conservations standards
rulemaking, available at https://www.regulations.gov/#!documentDetail;D=EERE-2008-BT-STD-0019-0047.
---------------------------------------------------------------------------
In today's rule, DOE proposes adding a new section 3.8.5 in both
appendix J1 and appendix J2 to specify that manufacturers may perform
up to two additional replications of the RMC measurement, for a total
of three independent RMC measurements for the tested unit, and use the
average of the three measurements as the basis for the calculation of
per-cycle energy consumption for removal of moisture from the test
load.
DOE also proposes to add the RMC measurement to the list of public
product-specific information contained in the certification reports for
residential clothes washers, as described in 10 CFR 429.20(b)(2)(i) and
(ii). DOE also proposes in newly created 10 CFR 429.20(a)(4) that the
certified RMC value of any clothes washer basic model shall be the mean
of the final RMC value measured for all tested units of the basic
model.
Finally, DOE proposes to add provisions in newly created section 10
CFR 429.134(c)(1) specifying that during assessment or enforcement
testing, the measured RMC value of a tested unit will be considered the
tested unit's final RMC value if the measured RMC value is within two
RMC percentage points of the certified RMC value of the basic model
(expressed as a percentage), or if the measured RMC value is lower than
the certified RMC value. DOE proposes a threshold of two RMC percentage
points because such a variation would limit the variation in the
overall MEF or IMEF calculation to roughly five percent.
If the measured RMC value of a tested unit is more than two RMC
percentage points higher than the certified RMC value of the basic
model, DOE will perform two additional replications of the RMC
measurement, each pursuant to the provisions of newly added section
3.8.5 of appendix J1 and appendix J2, for a total of three independent
RMC measurements of the tested unit. The average of the three RMC
measurements will be considered the tested unit's final RMC value and
will be used as the basis for the calculation of per-cycle energy
consumption for removal of moisture from the test load for that unit.
2. Rounding Requirements for All Reported Values
DOE proposes adding a new section at 10 CFR 429.20(c) to specify
the rounding requirements of all reported values for residential
clothes washers as follows: MEF and IMEF to the nearest 0.01 cu ft/kWh/
cycle, WF and IWF to the nearest 0.1 gal/cycle/cu ft, RMC to the
nearest 0.1 percentage point, and clothes container capacity to the
nearest 0.1 cu ft.
3. Energy Test Cycle Selections
As amended by the March 2012 final rule, 10 CFR 429.20(b)(3)
requires certification reports based on testing conducted in accordance
with appendix J2 to include a list of all cycle selections comprising
the complete energy test cycle for each basic model. DOE believes that
this reporting requirement should also pertain when appendix J1 is
used, particularly due to the difference in wording of the energy test
cycle definition in appendix J1. Therefore, DOE proposes to amend 10
CFR 429.20(b)(3) to require a list of all cycle selections comprising
the complete energy test cycle for each basic model, regardless of
whether the certification is based on testing conducted in accordance
with appendix J1 or appendix J2.
IV. Procedural Issues and Regulatory Review
A. Review Under Executive Order 12866
The Office of Management and Budget has determined that test
procedure
[[Page 23071]]
rulemakings do not constitute ``significant regulatory actions'' under
section 3(f) of Executive Order 12866, Regulatory Planning and Review,
58 FR 51735 (Oct. 4, 1993). Accordingly, this action was not subject to
review under the Executive Order by the Office of Information and
Regulatory Affairs (OIRA) in the Office of Management and Budget (OMB).
B. Review Under the Regulatory Flexibility Act
The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires
preparation of a regulatory flexibility analysis (IFRA) for any rule
that by law must be proposed for public comment, unless the agency
certifies that the rule, if promulgated, will not have a significant
economic impact on a substantial number of small entities. As required
by Executive Order 13272, ``Proper Consideration of Small Entities in
Agency Rulemaking,'' 67 FR 53461 (August 16, 2002), DOE published
procedures and policies on February 19, 2003, to ensure that the
potential impacts of its rules on small entities are properly
considered during the DOE rulemaking process. 68 FR 7990. DOE has made
its procedures and policies available on the Office of the General
Counsel's Web site: https://energy.gov/gc/office-general-counsel.
DOE reviewed today's proposed rule under the provisions of the
Regulatory Flexibility Act and the procedures and policies published on
February 19, 2003. Today's NOPR would amend DOE's test procedure by
codifying guidance interpreting DOE's existing regulations, providing
further clarifying interpretation of the relevant test procedure
provisions, correcting formatting errors, providing improved overall
organization, and removing certain testing provisions within the
current test procedures. DOE has concluded that the rule would not have
a significant impact on a substantial number of small entities. The
factual basis for this certification is as follows:
The Small Business Administration (SBA) considers a business entity
to be a small business, if, together with its affiliates, it employs
less than a threshold number of workers specified in 13 CFR Part 121.
These size standards and codes are established by the 2007 North
American Industry Classification System (NAICS). The threshold number
for NAICS classification code 335224, which applies to household
laundry equipment manufacturers and includes residential clothes washer
manufacturers, is 1,000 employees. Searches of the SBA Web site \4\ to
identify clothes washer manufacturers within this NAICS code identified
one small business. This small business manufactures laundry
appliances, including residential clothes washers.

DOE estimates that the clarified description of the capacity
measurement would take the same amount of time to conduct as the
capacity measurement analyzed in the March 2012 final rule. DOE
believes that use of an alternate bracing method for front-loading
clothes washers that do not contain shipping bolts or other bracing
hardware is already current practice among manufacturers of such
clothes washers. Additionally, DOE notes that the identified small
business produces only a single platform of top-loading clothes
washers, for which the proposed alternate bracing method would not be
applicable.
Regarding the potential increased testing burden associated with
maintaining a five degree tolerance on supply water temperatures for
clothes washers in which electrical energy consumption or water energy
consumption are affected by the inlet water temperature. One method for
achieving this temperature tolerance would be to use electronically
controlled water mixing valves on both the cold and hot water supply
lines. DOE estimates a capital cost of approximately $2,500 for
installing electronically controlled water mixing valves on a single
test stand. DOE notes that the identified small business currently does
not manufacturer this type of clothes washer; therefore, DOE does not
expect this proposed amendment to require any changes to the testing
hardware currently used by the small business.
DOE does not expect any of the clarifications to the energy test
cycle definition or the standby and off mode measurements to affect the
total length of testing time. Regarding any potential increase in test
burden as a result of its proposal to eliminate the separate testing
provisions for clothes washers with uniformly distributed warm wash
temperatures. DOE notes that the total testing time would be no greater
than for clothes washers with the same number of warm wash temperature
options, but with non-uniformly distributed temperatures, which DOE
observes constitutes the majority of the market. DOE also notes that
the clothes washers manufactured by the identified small business do
not contain uniformly distributed warm wash temperatures, and thus the
small business will not be affected by the proposed amendment.
Finally, the remaining proposed changes in today's NOPR are
intended to clarify the existing test methods without adding any
additional requirements and therefore would not result in additional
burden.
For the reasons stated above, DOE certifies that the proposed test
procedure amendments would not have a significant impact on a
substantial number of small entities. DOE will submit a certification
and supporting statement of factual basis to the Chief Counsel for
Advocacy of the SBA for review under 5 U.S.C. 605(b).
C. Review Under the Paperwork Reduction Act of 1995
Manufacturers of residential clothes washers must certify to DOE
that their products comply with any applicable energy conservation
standards. In certifying compliance, manufacturers must test their
products according to the DOE test procedures for clothes washers,
including any amendments adopted for those test procedures. DOE has
established regulations for the certification and recordkeeping
requirements for all covered consumer products and commercial
equipment, including residential clothes washers. (76 FR 12422 (March
7, 2011). The collection-of-information requirement for the
certification and recordkeeping is subject to review and approval by
OMB under the Paperwork Reduction Act (PRA). This requirement has been
approved by OMB under OMB control number 1910-1400. Public reporting
burden for the certification is estimated to average 20 hours per
response, including the time for reviewing instructions, searching
existing data sources, gathering and maintaining the data needed, and
completing and reviewing the collection of information.
Notwithstanding any other provision of the law, no person is
required to respond to, nor shall any person be subject to a penalty
for failure to comply with, a collection of information subject to the
requirements of the PRA, unless that collection of information displays
a currently valid OMB Control Number.
D. Review Under the National Environmental Policy Act of 1969
In this proposed rule, DOE proposes test procedure amendments that
it expects will be used to develop and implement future energy
conservation standards for residential clothes washers. DOE has
determined that this rule falls into a class of actions that are
categorically excluded from review
[[Page 23072]]
under the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et
seq.) and DOE's implementing regulations at 10 CFR Part 1021.
Specifically, this proposed rule would amend the existing test
procedures without affecting the amount, quality or distribution of
energy usage, and, therefore, would not result in any environmental
impacts. Thus, this rulemaking is covered by Categorical Exclusion A5
under 10 CFR Part 1021, subpart D, which applies to any rulemaking that
interprets or amends an existing rule without changing the
environmental effect of that rule. Accordingly, neither an
environmental assessment nor an environmental impact statement is
required.
E. Review Under Executive Order 13132
Executive Order 13132, ``Federalism,'' 64 FR 43255 (August 4, 1999)
imposes certain requirements on agencies formulating and implementing
policies or regulations that preempt State law or that have Federalism
implications. The Executive Order requires agencies to examine the
constitutional and statutory authority supporting any action that would
limit the policymaking discretion of the States and to carefully assess
the necessity for such actions. The Executive Order also requires
agencies to have an accountable process to ensure meaningful and timely
input by State and local officials in the development of regulatory
policies that have Federalism implications. On March 14, 2000, DOE
published a statement of policy describing the intergovernmental
consultation process it will follow in the development of such
regulations. 65 FR 13735. DOE examined this proposed rule and
determined that it will not have a substantial direct effect on the
States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government. EPCA governs and prescribes Federal
preemption of State regulations as to energy conservation for the
products that are the subject of today's proposed rule. States can
petition DOE for exemption from such preemption to the extent, and
based on criteria, set forth in EPCA. (42 U.S.C. 6297(d)) No further
action is required by Executive Order 13132.
F. Review Under Executive Order 12988
Regarding the review of existing regulations and the promulgation
of new regulations, section 3(a) of Executive Order 12988, ``Civil
Justice Reform,'' 61 FR 4729 (Feb. 7, 1996), imposes on Federal
agencies the general duty to adhere to the following requirements: (1)
Eliminate drafting errors and ambiguity; (2) write regulations to
minimize litigation; (3) provide a clear legal standard for affected
conduct rather than a general standard; and (4) promote simplification
and burden reduction. Section 3(b) of Executive Order 12988
specifically requires that Executive agencies make every reasonable
effort to ensure that the regulation: (1) Clearly specifies the
preemptive effect, if any; (2) clearly specifies any effect on existing
Federal law or regulation; (3) provides a clear legal standard for
affected conduct while promoting simplification and burden reduction;
(4) specifies the retroactive effect, if any; (5) adequately defines
key terms; and (6) addresses other important issues affecting clarity
and general draftsmanship under any guidelines issued by the Attorney
General. Section 3(c) of Executive Order 12988 requires Executive
agencies to review regulations in light of applicable standards in
sections 3(a) and 3(b) to determine whether they are met or it is
unreasonable to meet one or more of them. DOE has completed the
required review and determined that, to the extent permitted by law,
this proposed rule meets the relevant standards of Executive Order
12988.
G. Review Under the Unfunded Mandates Reform Act of 1995
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA)
requires each Federal agency to assess the effects of Federal
regulatory actions on State, local, and Tribal governments and the
private sector. Public Law 104-4, sec. 201 (codified at 2 U.S.C. 1531).
For a proposed regulatory action likely to result in a rule that may
cause the expenditure by State, local, and Tribal governments, in the
aggregate, or by the private sector of $100 million or more in any one
year (adjusted annually for inflation), section 202 of UMRA requires a
Federal agency to publish a written statement that estimates the
resulting costs, benefits, and other effects on the national economy.
(2 U.S.C. 1532(a), (b)) The UMRA also requires a Federal agency to
develop an effective process to permit timely input by elected officers
of State, local, and Tribal governments on a proposed ``significant
intergovernmental mandate,'' and requires an agency plan for giving
notice and opportunity for timely input to potentially affected small
governments before establishing any requirements that might
significantly or uniquely affect small governments. On March 18, 1997,
DOE published a statement of policy on its process for
intergovernmental consultation under UMRA. 62 FR 12820; also available
at https://energy.gov/gc/office-general-counsel. DOE examined today's
proposed rule according to UMRA and its statement of policy and
determined that the proposal contains neither an intergovernmental
mandate, nor a mandate that may result in the expenditure of $100
million or more in any year, so these requirements do not apply.
H. Review Under the Treasury and General Government Appropriations Act,
1999
Section 654 of the Treasury and General Government Appropriations
Act, 1999 (Pub. L. 105-277) requires Federal agencies to issue a Family
Policymaking Assessment for any rule that may affect family well-being.
This rule would not have any impact on the autonomy or integrity of the
family as an institution. Accordingly, DOE has concluded that it is not
necessary to prepare a Family Policymaking Assessment.
I. Review Under Executive Order 12630
DOE has determined, under Executive Order 12630, ``Governmental
Actions and Interference with Constitutionally Protected Property
Rights'' 53 FR 8859 (March 18, 1988), that this regulation would not
result in any takings that might require compensation under the Fifth
Amendment to the U.S. Constitution.
J. Review Under Treasury and General Government Appropriations Act,
2001
Section 515 of the Treasury and General Government Appropriations
Act, 2001 (44 U.S.C. 3516 note) provides for agencies to review most
disseminations of information to the public under guidelines
established by each agency pursuant to general guidelines issued by
OMB. OMB's guidelines were published at 67 FR 8452 (Feb. 22, 2002), and
DOE's guidelines were published at 67 FR 62446 (Oct. 7, 2002). DOE has
reviewed today's proposed rule under the OMB and DOE guidelines and has
concluded that it is consistent with applicable policies in those
guidelines.
K. Review Under Executive Order 13211
Executive Order 13211, ``Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use,'' 66 FR 28355
(May 22, 2001), requires Federal agencies to prepare and submit to OMB,
a Statement of Energy Effects for any proposed significant energy
action. A ``significant energy action'' is defined as
[[Page 23073]]
any action by an agency that promulgated or is expected to lead to
promulgation of a final rule, and that: (1) Is a significant regulatory
action under Executive Order 12866, or any successor order; and (2) is
likely to have a significant adverse effect on the supply,
distribution, or use of energy; or (3) is designated by the
Administrator of OIRA as a significant energy action. For any proposed
significant energy action, the agency must give a detailed statement of
any adverse effects on energy supply, distribution, or use should the
proposal be implemented, and of reasonable alternatives to the action
and their expected benefits on energy supply, distribution, and use.
Today's regulatory action to amend the test procedure for measuring
the energy efficiency of residential clothes washers is not a
significant regulatory action under Executive Order 12866. Moreover, it
would not have a significant adverse effect on the supply,
distribution, or use of energy, nor has it been designated as a
significant energy action by the Administrator of OIRA. Therefore, it
is not a significant energy action, and, accordingly, DOE has not
prepared a Statement of Energy Effects.
L. Review Under Section 32 of the Federal Energy Administration Act of
1974
Under section 301 of the Department of Energy Organization Act
(Pub. L. 95-91; 42 U.S.C. 7101), DOE must comply with section 32 of the
Federal Energy Administration Act of 1974, as amended by the Federal
Energy Administration Authorization Act of 1977. (15 U.S.C. 788; FEAA)
Section 32 essentially provides in relevant part that, where a proposed
rule authorizes or requires use of commercial standards, the notice of
proposed rulemaking must inform the public of the use and background of
such standards. In addition, section 32(c) requires DOE to consult with
the Attorney General and the Chairman of the Federal Trade Commission
(FTC) concerning the impact of the commercial or industry standards on
competition. DOE is not requiring the use of any new commercial
standards in this rulemaking, so these requirements do not apply.

interest.
It is DOE's policy that all comments may be included in the public
docket, without change and as received, including any personal
information provided in the comments (except information deemed to be
exempt from public disclosure).
B. Issues on Which DOE Seeks Comment
Although DOE welcomes comments on any aspect of this proposal, DOE
is particularly interested in receiving comments and views of
interested parties concerning the following issues:
(1) The normal cycle definition and whether it adequately covers
the cycle setting most commonly chosen by users of washing machines;
(2) The potential test burden associated with maintaining a
tolerance of five degrees on the hot and cold water supply temperature
ranges for clothes washers in which electrical energy and water energy
consumption are affected by the inlet water temperature;
(3) The potential increase in test burden associated with removing
the separate testing provisions for clothes washers with uniformly
distributed warm wash temperatures.
(4) Whether any discrepancies exist when determining the wash/rinse
temperature selections comprising the energy test cycle in appendix J2
using the proposed flowcharts compared to using the current energy test
cycle definition (and, if so, specific examples of cycle setting
configurations that would lead to the discrepancies); and
(5) Whether the methodology presented in the energy test cycle
flowcharts in appendix J2 could result in an efficiency rating
unrepresentative of how a particular clothes washer would be used by
consumers.
VI. Approval of the Office of the Secretary
The Secretary of Energy has approved publication of this proposed
rule.

the Energy Consumption of Automatic and Semi-automatic Clothes Washers
Note: Any representation related to the energy or water
consumption of clothes washers made after [insert date 180 days
after date of publication of any test procedure final rule in the
Federal Register] must be made based upon results generated using
this appendix or Appendix J2. Any representation related to the
energy or water consumption of clothes washers made between [insert
date 30 days after date of publication of any test procedure final
rule in the Federal Register] and [insert date 180 days after date
of publication of any test procedure final rule in the Federal
Register] must be based upon results generated either under this
Appendix J1 or Appendix J2, or upon the test procedures in Appendix
J1 or Appendix J2 as they appeared at 10 CFR part 430, subpart B,
Appendix J1 or J2, in the 10 CFR parts 200 to 499 edition revised as
of January 1, 2013. Manufacturers must use a single appendix for all
representations, including certifications of compliance. Compliance
with DOE's amended standards for residential clothes washers, and
corresponding use of the test procedures at Appendix J2 for all
representations by residential clothes washer manufacturers,
including certifications of compliance, is required as of March 7,
2015.
* * * * *
1.1. Adaptive control system means a clothes washer control
system, other than an adaptive water fill control system, that is
capable of automatically adjusting washer operation or washing
conditions based on characteristics of the clothes load placed in
the clothes container, without allowing or requiring user
intervention or actions. The automatic adjustments may, for example,
include automatic selection, modification, or control of any of the
following: wash water temperature, agitation or tumble cycle time,
number of rinse cycles, and spin speed. The characteristics of the
clothes load, which could trigger such adjustments, could, for
example, consist of or be indicated by the presence of either soil,
soap, suds, or any other additive laundering substitute or
complementary product.
1.2 Adaptive water fill control system means a clothes washer
automatic water fill control system that is capable of automatically
adjusting the water fill level based on the size or weight of the

3.1.1 Place the clothes washer in such a position that the
uppermost edge of the clothes container opening is leveled
horizontally, so that the container will hold the maximum amount of
water. For front-loading clothes washers, the door seal and shipping
bolts or other forms of bracing hardware to support the wash drum
during shipping must remain in place during the capacity
measurement.
If the design of a front-loading clothes washer does not include
shipping bolts or other forms of bracing hardware to support the
wash drum during shipping, a laboratory may support the wash drum by
other means, including temporary bracing or support beams. Any
temporary bracing or support beams must keep the wash drum in a
fixed position, relative to the geometry of the door and door seal
components, that is representative of the position of the wash drum
during normal operation. The method used must avoid damage to the
unit that would affect the results of the energy and water testing.
The test report must document the method used to support the wash
drum, and pursuant to Sec. 429.71 of this chapter, the manufacturer
must retain such documentation as part of its test records.
3.1.2 Line the inside of the clothes container with a 2 mil
thickness (0.051 mm) plastic sheet or plastic bag. All clothes
washer components that occupy space within the clothes container and
that are recommended for use during a wash cycle must be in place
and must be lined with a 2 mil thickness (0.051 mm) plastic sheet or
plastic bag to prevent water from entering any void space.

[GRAPHIC] [TIFF OMITTED] TP25AP14.018
For a front-loading horizontal-axis clothes washer, fill the
clothes container to the highest point of contact between the door
and the door gasket. If any portion of the door or gasket would
occupy the measured volume space when the door is closed, exclude
the volume that the door or gasket portion would occupy from the
measurement. For a front-loading horizontal-axis clothes washer with
a concave door shape, include any additional volume above the plane
defined by the highest point of contact between the door and the
door gasket, if that area can be occupied by clothing during washer
operation. For a top-loading horizontal-axis clothes washer, include
any additional volume above the plane of the door hinge that
clothing could occupy during washer operation. Figure 3.1.4.3
illustrates the maximum fill volumes for all horizontal-axis clothes
washer types.
[[Page 23080]]
[GRAPHIC] [TIFF OMITTED] TP25AP14.019
For all clothes washers, exclude any volume that cannot be
occupied by the clothing load during operation.
3.1.5 Measure and record the weight of water, W, in pounds.
3.1.6 Calculate the clothes container capacity as follows:
C = W/d
Where:
C = Capacity in cubic feet (liters).
W = Mass of water in pounds (kilograms).
d = Density of water (62.0 lbs/ft\3\ for 100[emsp14][deg]F (993 kg/
m\3\ for 37.8 [deg]C) or 62.3 lbs/ft\3\ for 60[emsp14][deg]F (998
kg/m\3\ for 15.6 [deg]C)).
3.1.7 Calculate the clothes container capacity, C, to the
nearest 0.01 cubic foot for the purpose of determining test load
sizes per Table 5.1 of this appendix and for all subsequent
calculations in this appendix that include the clothes container
capacity.

3.2 Procedure for measuring water and energy consumption values
on all automatic and semi-automatic washers. All energy consumption
tests shall be performed under the energy test cycle(s), unless
otherwise specified. Table 3.2 indicates the sections below that
govern tests of particular clothes washers, based on the number of
wash/rinse temperature selections available on the model and also,
in some instances, method of water heating. The procedures
prescribed are applicable regardless of a clothes washer's washing
capacity, loading port location, primary axis of rotation of the
clothes container, and type of control system. Data from a wash
cycle that terminates prematurely if an out-of-balance condition is
detected, and thus does not include the agitation/tumble operation,
spin speed(s), wash times, and rinse times applicable to the wash
cycle under test, shall be discarded.
* * * * *
3.2.3. Clothes washers with automatic water fill/manual water
fill control systems.
3.2.3.1 Clothes washers with automatic water fill control system
and alternate manual water fill control system. If a clothes washer
with an automatic water fill control system allows user selection of
manual controls as an alternative, then both manual and automatic
modes shall be tested and, for each mode, the energy consumption
(HET, MET, and DE) and water
consumption (QT) values shall be calculated as set forth
in section 4. Then the average of the two values (one from each
mode, automatic and manual) for each variable shall be used in
section 4 for the clothes washer.
3.2.3.2 Clothes washers with automatic water fill control
system.
* * * * *
3.2.3.2.2 User-adjustable. Four tests shall be conducted on
clothes washers with user-adjustable automatic water fill controls
that affect the relative wash water levels. The first test shall be
conducted using the maximum test load and with the automatic water
fill control system set in the setting that will give the most
energy intensive result. The second test shall be conducted with the
minimum test load and with the automatic water fill control system
set in the setting that will give the least energy intensive result.
The third test shall be conducted with the average test load and
with the automatic water fill control system set in the setting that
will give the most energy intensive result for the given test load.
The fourth test shall be conducted with the average test load and
with the automatic water fill control system set in the setting that
will give the least energy intensive result for the given test load.
The energy and water consumption for the average test load and water
level shall be the average of the third and fourth tests.

at all discrete selections, or test at 25 percent, 50 percent, and
75 percent positions of the temperature selection device between the
hottest hot (<=135[emsp14][deg]F (57.2 [deg]C)) wash and the coldest
cold wash. If a selection is not available at the 25, 50 or 75
percent position, in place of each such unavailable selection use
the next warmer setting. Each reportable value to be used for the
warm water wash setting shall be the arithmetic average of all tests
conducted pursuant to this section.
3.5.1 Maximum test load and water fill. Hot water consumption
(Hwx), cold water consumption (Cwx), and electrical energy
consumption (Ewx) shall be measured with the controls set for the

To load the energy test cloths in a top-loading clothes washer,
arrange the cloths circumferentially around the axis of rotation of
the clothes container, using alternating lengthwise orientations for
adjacent pieces of cloth. Complete each cloth layer across its
horizontal plane within the clothes container before adding a new
layer. Figure 2.9.2.2 of this appendix illustrates the correct
loading technique for a vertical-axis clothes washer.
To load the energy test cloths in a front-loading clothes
washer, arrange the cloths lengthwise, from front to back, using
alternating orientations for adjacent pieces of cloth. Load the
cloths evenly across the width of the clothes container. Complete
each cloth layer across its horizontal plane within the clothes
container before adding a new layer. Figure 2.9.2.3 of this appendix
illustrates the correct loading technique for a horizontal-axis
clothes washer.
For all clothes washers, follow any additional manufacturer
loading instructions provided to the user regarding the placement of
clothing within the clothing container.
[[Page 23085]]

3. Test Measurements
3.1 Clothes container capacity. Measure the entire volume that a
clothes load could occupy within the clothes container during active
mode washer operation according to the following procedures:
[[Page 23091]]
3.1.1 Place the clothes washer in such a position that the
uppermost edge of the clothes container opening is leveled
horizontally, so that the container will hold the maximum amount of
water. For front-loading clothes washers, the door seal and shipping
bolts or other forms of bracing hardware to support the wash drum
during shipping must remain in place during the capacity
measurement.
If the design of a front-loading clothes washer does not include
shipping bolts or other forms of bracing hardware to support the
wash drum during shipping, a laboratory may support the wash drum by
other means, including temporary bracing or support beams. Any
temporary bracing or support beams must keep the wash drum in a
fixed position, relative to the geometry of the door and door seal
components, that is representative of the position of the wash drum
during normal operation. The method used must avoid damage to the
unit that would affect the results of the energy and water testing.
The laboratory must fully document the method used to support the
wash drum, include such documentation in the final test report, and
pursuant to Sec. 429.71 of this chapter, the manufacturer must
retain such documentation as part its test records.
3.1.2 Line the inside of the clothes container with a 2 mil
thickness (0.051 mm) plastic sheet or plastic bag. All clothes
washer components that occupy space within the clothes container and
that are recommended for use during a wash cycle must be in place
and must be lined with a 2 mil thickness (0.051 mm) plastic sheet or
plastic bag to prevent water from entering any void space.
3.1.3 Record the total weight of the machine before adding
water.
3.1.4 Fill the clothes container manually with either 60 [deg]F
5 [deg]F (15.6 [deg]C 2.8 [deg]C) or 100
[deg]F 10 [deg]F (37.8 [deg]C 5.5 [deg]C)
water, with the door open. For a top-loading vertical-axis clothes
washer, fill the clothes container to the uppermost edge of the
rotating portion, including any balance ring. Figure 3.1.4.1 of this
appendix illustrates the maximum fill level for top-loading clothes
washers.
[GRAPHIC] [TIFF OMITTED] TP25AP14.027
For a front-loading horizontal-axis clothes washer, fill the
clothes container to the highest point of contact between the door
and the door gasket. If any portion of the door or gasket would
occupy the measured volume space when the door is closed, exclude
from the measurement the volume that the door or gasket portion
would occupy. For a front-loading horizontal-axis clothes washer
with a concave door shape, include any additional volume above the
plane defined by the highest point of contact between the door and
the door gasket, if that area can be occupied by clothing during
washer operation. For a top-loading horizontal-axis clothes washer,
include any additional volume above the plane of the door hinge that
clothing could occupy during washer operation. Figure 3.1.4.2 of
this appendix illustrates the maximum fill volumes for all
horizontal-axis clothes washer types.
[GRAPHIC] [TIFF OMITTED] TP25AP14.028
[[Page 23092]]
For all clothes washers, exclude any volume that cannot be
occupied by the clothing load during operation.
3.1.5 Measure and record the weight of water, W, in pounds.
3.1.6 Calculate the clothes container capacity as follows:
C = W/d
Where:
C = Capacity in cubic feet (liters).
W = Mass of water in pounds (kilograms).
d = Density of water (62.0 lbs/ft\3\ for 100[emsp14][deg]F (993 kg/
m\3\ for 37.8 [deg]C) or 62.3 lbs/ft\3\ for 60[emsp14][deg]F (998
kg/m\3\ for 15.6 [deg]C)).
3.1.7 Calculate the clothes container capacity, C, to the
nearest 0.01 cubic foot for the purpose of determining test load
sizes per Table 5.1 of this appendix and for all subsequent
calculations that include the clothes container capacity.
3.2 Procedure for measuring water and energy consumption values
on all automatic and semi-automatic washers.
3.2.1 Perform all energy consumption tests under the energy test
cycle.
3.2.2 Perform the test sections listed in Table 3.2.2 in
accordance with the wash/rinse temperature selections available in
the energy test cycle.

3.2.3 Hot and cold water faucets.
3.2.3.1 For automatic clothes washers, open both the hot and
cold water faucets.
3.2.3.2 For semi-automatic washers:
(1) For hot inlet water temperature, open the hot water faucet
completely and close the cold water faucet;
(2) For warm inlet water temperature, open both hot and cold
water faucets completely;
(3) For cold inlet water temperature, close the hot water faucet
and open the cold water faucet completely.
3.2.4 Wash/rinse temperature selection. Set the wash/rinse
temperature selection control to obtain the desired wash/rinse
temperature selection within the energy test cycle.
3.2.5 Wash time setting. If one wash time is prescribed for the
wash cycle under test, that shall be the wash time setting;
otherwise, the wash time setting shall be the higher of either the
minimum or 70 percent of the maximum wash time available for the
wash cycle under test, regardless of the labeling of suggested dial
locations. If the clothes washer is equipped with an
electromechanical dial controlling wash time, reset the dial to the
minimum wash time and then turn it in the direction of increasing
wash time to reach the appropriate setting. If the appropriate
setting is passed, return the dial to the minimum wash time and then
turn in the direction of increasing wash time until the appropriate
setting is reached.
3.2.6 Water fill levels.
3.2.6.1 Clothes washers with manual water fill control system.
Set the water fill selector to the maximum water level available for
the maximum test load size and the minimum water level available for
the minimum test load size.
3.2.6.2 Clothes washers with automatic water fill control
system.
3.2.6.2.1 Not user adjustable. The maximum, minimum, and average
water levels as described in the following sections refer to the
amount of water fill that is automatically selected by the control
system when the respective test loads are used.
3.2.6.2.2 User adjustable. Conduct four tests on clothes washers
with user adjustable automatic water fill controls that affect the
relative wash water levels. Conduct the first test using the maximum
test load and with the automatic water fill control system set in
the setting that will give the most energy intensive result. Conduct
the second test using the minimum test load and with the automatic
water fill control system set in the setting that will give the
least energy intensive result. Conduct the third test using the
average test load and with the automatic water fill control system
set in the setting that will give the most energy intensive result
for the given test load. Conduct the fourth test using the average
test load and with the automatic water fill control system set in
the setting that will give the least energy intensive result for the
given test load. Average the results of the third and fourth tests
to obtain the energy and water consumption values for the average
test load size.
3.2.6.3 Clothes washers with automatic water fill control system
and alternate manual water fill control system. If a clothes washer
with an automatic water fill control system allows user selection of
manual controls as an alternative, test both manual and automatic
modes and, for each mode, calculate the energy consumption
(HET, MET, and DE) and water
consumption (QT) values as set forth in section 4 of this
appendix. Then, calculate the average of the two values (one from
each mode, automatic and manual) for each variable (HET,
MET, DE, and QT) and use the
average value for each variable in the final calculations in section
4 of this appendix.
3.2.7 Manufacturer default settings. For all wash cycles tested,
use the manufacturer default settings, except for (1) the
temperature selection, (2) the wash water fill levels, or (3) if
necessary, the spin speeds on wash cycles used to determine
remaining moisture content. This includes wash conditions such as
agitation/tumble operation, soil level, spin speed on wash cycles
used to determine energy and water consumption, wash times, rinse
times, optional rinse settings, water heating time for water heating
clothes washers, and all other wash parameters or optional features
applicable to that wash cycle. Include any optional wash cycle
feature for testing (other than wash/rinse temperature, water fill
level selection, or spin speed on wash cycles used to determine
remaining moisture content) that is activated by default on the wash
cycle under test unless the manufacturer instructions recommend not
selecting this option for washing normally soiled cotton or linen
clothes.
3.2.8 For each wash cycle tested, include the entire active
washing mode and exclude any delay start or cycle finished modes.
3.2.9 Discard the data from a wash cycle that terminates
prematurely if an out-of-balance condition is detected, and thus
does not include the agitation/tumble operation, spin speed(s), wash
times, and rinse times applicable to the wash cycle under test.
3.3 Extra Hot wash/Cold rinse. Measure the water and electrical
energy consumption for each water fill level and test load size as
specified in sections 3.3.1 through 3.3.3 of this appendix for the
Extra Hot wash/Cold rinse as defined within the energy test cycle.
Testing parties may use non-reversible temperature indicator
labels, adhered to the inside of the clothes container, to determine
the maximum water temperature during the wash cycle. If using a
temperature indicator label to test a front-loading clothes washer,
adhere the label along the inner circumference of the clothes
container drum, midway between the front and the back of the clothes
container. If using a temperature indicator label to test a top-
loading clothes washer, adhere the label along the inner
circumference of the clothes container drum, as close to the bottom
of the container as possible.

6. Waivers and Field Testing
6.1 Waivers and Field Testing for Nonconventional Clothes
Washers. Manufacturers of nonconventional clothes washers, such as
clothes washers with adaptive control systems, must submit a
petition for waiver pursuant to 10 CFR 430.27 to establish an
acceptable test procedure for that clothes washer if the washer
cannot be tested pursuant to the DOE test procedure or the DOE test
procedure yields results that are so unrepresentative of the clothes
washer's true energy consumption characteristics as to provide
materially inaccurate comparative data. In such cases, field testing
may be appropriate for establishing an acceptable test procedure.
The following are guidelines for field testing that may be used by
manufacturers in support of petitions for waiver. These guidelines
are not mandatory and the Department may determine that they do not
apply to a particular model. Depending upon a manufacturer's
approach for conducting field testing, additional data may be
required. Manufacturers are encouraged to communicate with the
Department prior to the commencement of field tests that may be used
to support a petition for waiver. Section 6.3 of this appendix
provides an example of
[[Page 23098]]
field testing for a clothes washer with an adaptive water fill
control system. Other features, such as the use of various spin
speed selections, could be the subject of field tests.
6.2 Nonconventional Wash System Energy Consumption Test. The
field test may consist of a minimum of 10 of the nonconventional
clothes washers (``test clothes washers'') and 10 clothes washers
already being distributed in commerce (``base clothes washers'').
The tests should include a minimum of 50 wash cycles per clothes
washer. The test clothes washers and base clothes washers should be
identical in construction except for the controls or systems being
tested. Equal numbers of both the test clothes washer and the base
clothes washer should be tested simultaneously in comparable
settings to minimize seasonal or end-user laundering conditions or
variations. The clothes washers should be monitored in such a way as
to accurately record the average total energy and water consumption
per cycle, including water heating energy when electrically heated
water is used, and the energy required to remove the remaining
moisture of the test load. Standby and off mode energy consumption
should be measured according to section 4.4 of this test procedure.
The field test results should be used to determine the best method
to correlate the rating of the test clothes washer to the rating of
the base clothes washer.
6.3 Adaptive water fill control system field test. (1) Section
3.2.6.3 of this appendix defines the test method for measuring
energy consumption for clothes washers that incorporate both
adaptive (automatic) and alternate manual water fill control
systems. Energy consumption calculated by the method defined in
section 3.2.6.3 of this appendix assumes the adaptive cycle will be
used 50 percent of the time. This section can be used to develop
field test data in support of a petition for waiver when it is
believed that the adaptive cycle will be used more than 50 percent
of the time. The field test sample size should be a minimum of 10
test clothes washers. The test clothes washers should be
representative of the design, construction, and control system that
will be placed in commerce. The duration of field testing in the
user's house should be a minimum of 50 wash cycles, for each unit.
No special instructions as to cycle selection or product usage
should be given to the field test participants, other than inclusion
of the product literature pack that would be shipped with all units,
and instructions regarding filling out data collection forms, use of
data collection equipment, or basic procedural methods. Prior to the
test clothes washers being installed in the field test locations,
baseline data should be developed for all field test units by
conducting laboratory tests as defined by section 1 through section
5 of this appendix to determine the energy consumption, water
consumption, and remaining moisture content values. The following
data should be measured and recorded for each wash load during the
test period: wash cycle selected, the mode of the clothes washer
(adaptive or manual), clothes load dry weight (measured after the
clothes washer and clothes dryer cycles are completed) in pounds,
and type of articles in the clothes load (e.g., cottons, linens,
permanent press). The wash cycles used in calculating the in-home
percentage split between adaptive and manual cycle usage should be
only those wash cycles that conform to the definition of the energy
test cycle.
Calculate:
T = The total number of wash cycles run during the field test.
Ta = The total number of adaptive control wash cycles.
Tm = The total number of manual control wash cycles.
The percentage weighting factors:
Pa = (Ta/T) x 100% (the percentage weighting
for adaptive control selection)
Pm = (Tm/T) x 100% (the percentage weighting
for manual control selection)
(2) Energy consumption (HET, MET, and
DE) and water consumption (QT) values
calculated in section 4 of this appendix for the manual and adaptive
modes should be combined using Pa and Pm as
the weighting factors.

8. Add a new Appendix J3 to subpart B of part 430 to read as follows:
Appendix J3 to Subpart B of Part 430-Uniform Test Method for Measuring
the Moisture Absorption and Retention Characteristics of New Energy
Test Cloth Lots
Note: DOE maintains an historical record of the standard
extractor test data and final correctio5tn curve coefficients for
each approved lot of energy test cloth. These can be accessed
through DOE's Web page for standards and test procedures for
residential clothes washers at DOE's Building Technologies Office
Appliance and Equipment Standards Web site.
1. Objective
The following procedure is used to evaluate the moisture
absorption and retention characteristics of a new lot of test cloth
by measuring the remaining moisture content (RMC) in a standard
extractor at a specified set of conditions. The results are used to
develop a set of coefficients that correlate the measured RMC values
of the new test cloth lot with a set of standard RMC values
established as an historical reference point. These correction
coefficients are applied to the RMC measurements performed during
testing according to appendix J1 or appendix J2 to 10 CFR 430
subpart B, ensuring that the final corrected RMC measurement for a
clothes washer remains independent of the test cloth lot used for
testing.
2. Definitions
2.1 AHAM means the Association of Home Appliance Manufacturers.
2.2 Bone-dry means a condition of a load of test cloth that has
been dried in a dryer at maximum temperature for a minimum of 10
minutes, removed and weighed before cool down, and then dried again
for 10 minute periods until the final weight change of the load is 1
percent or less.
2.3 Lot means a quantity of cloth that has been manufactured
with the same batches of cotton and polyester during one continuous
process.
3. Testing Conditions
3.1 Table 3.1 of this appendix provides the matrix of test
conditions. In the table, ``g Force'' represents units of
gravitational acceleration. When this matrix is repeated 3 times, a
total of 60 extractor RMC test runs are required. For the purpose of
the extractor RMC test, the test cloths may be used for up to 60
test runs (after preconditioning as specified in appendix J1 or
appendix J2).

3.2 Perform the standard extractor RMC tests using a North Star
Engineered Products Inc. (formerly Bock) Model 215 extractor (having
a basket diameter of 20 inches, height of 11.5 inches, and volume of
2.09 ft\3\), with a variable speed drive (North Star Engineered
Products, P.O. Box 5127, Toledo, OH 43611) or an equivalent
extractor with same basket design (i.e. diameter, height, volume,
and hole configuration) and variable speed drive. Table 3.2 shows
the extractor spin speed, in revolutions per minute (RPM), that must
be used to attain each required g-force level.

3.3 Bone dryer temperature. The dryer used for bone drying must
heat the test cloth and energy stuffer cloths above 210 [deg]F (99
[deg]C).
4. Test Loads
4.1 Preconditioning. New test cloths, including energy test
cloths and energy stuffer cloths, must be pre-conditioned in a
clothes washer in the following manner:
Perform five complete wash-rinse-spin cycles, the first two with
current AHAM Standard detergent Formula 3 and the last three without
detergent. Place the test cloth in a clothes washer set at the
maximum water level. Wash the load for ten minutes in soft water (17
ppm hardness or less) using 27.0 grams + 4.0 grams per pound of
cloth load of AHAM Standard detergent Formula 3. The wash
temperature is to be controlled to 135[emsp14][deg]F 5[emsp14][deg]F (57.2 [deg]C 2.8 [deg]C) and the
rinse temperature is to be controlled to 60[emsp14][deg]F 5[emsp14][deg]F (15.6 [deg]C 2.8 [deg]C). Repeat
the cycle with detergent and then repeat the cycle three additional
times without detergent, bone drying the load between cycles (for a
total of five complete wash-rinse-spin cycles).
4.2 Test load composition. Test loads must be comprised of
randomly selected cloth at the beginning, middle and end of a lot.
4.3 Test load size. Use a test load size of 8.4 lbs. Two test
loads may be used for standard extractor RMC tests, with each load
used for half of the total number of required tests.
5. Test Measurements
5.1 Dry the test cloth until it is ``bone-dry'' according to the
definition in section 2.2 of this appendix. Record the bone-dry
weight of the test load (WI).
5.2 Prepare the test load for soak by grouping four test cloths
into loose bundles. Create the bundles by hanging four cloths
vertically from one corner and loosely wrapping the test cloth onto
itself to form the bundle. Bundles should be wrapped loosely to
ensure consistency of water extraction. Then place the bundles into
the water to soak. Eight to nine bundles will be formed depending on
the test load. The ninth bundle may not equal four cloths but can
incorporate energy stuffer cloths to help offset the size
difference.
5.3 Soak the test load for 20 minutes in 10 gallons of soft (<17
ppm) water. The entire test load must be submerged. Maintain a water
temperature of 100 [deg]F 5 [deg]F (37.8 [deg]C 2.8 [deg]C) at all times between the start and end of the
soak.
5.4 Remove the test load and allow each of the test cloth
bundles to drain over the water bath for a maximum of 5 seconds.
5.5 Manually place the test cloth bundles in the basket of the
extractor, distributing them evenly by eye. The draining and loading
process must take no longer than 1 minute. Spin the load at a fixed
speed corresponding to the intended centripetal acceleration level
(measured in units of the acceleration of gravity, g)
1g for the intended time period 5 seconds. Begin the
timer when the extractor meets the required spin speed for each
test.
5.6 Record the weight of the test load immediately after the
completion of the extractor spin cycle (WC).
5.7 Calculate the remaining moisture content of the test load as
(WC-WI)/WI.
5.8 Draining the soak tub is not necessary if the water bath is
corrected for water level and temperature before the next
extraction.
5.9 Drying the test load in between extraction runs is not
necessary. However, the bone dry weight must be checked after every
12 extraction runs to make sure the bone dry weight is within
tolerance (8.4 0.1 lb).
5.10 The test load must be soaked and extracted once following
bone drying, before continuing with the remaining extraction runs.
Perform this extraction at the same spin speed used for the
extraction run prior to bone drying, for a time period of 4 minutes.
Either warm or cold soak temperature may be used.
5.11 Measure the remaining moisture content of the test load at
five g levels: 100 g, 200 g, 350 g, 500 g, and 650 g, using two
different spin times at each g level: 4 minutes and 15 minutes.
5.12 Repeat sections 5.1 through 5.11 of this appendix using
soft (<17 ppm) water at 60[emsp14][deg]F
5[emsp14][deg]F (15.6 [deg]C 2.8 [deg]C).
6. Calculation of RMC Correction Curve
6.1 Average the values of 3 test runs, and fill in Table 3.1 of
this appendix. Perform a linear least-squares fit to determine
coefficients A and B such that the standard RMC values shown in
Table 6.1 of this appendix (RMCstandard) are linearly
related to the RMC values measured in section 5 of this appendix
(RMCcloth):
RMCstandard ~ A * RMCcloth + B
Where A and B are coefficients of the linear least-squares fit.

6.2 Perform an analysis of variance with replication test using
two factors, spin speed and lot, to check the interaction of speed
and lot. Use the values from Table 3.1 and Table 6.1 of this
appendix in the calculation. The ``P'' value of the F-statistic for
interaction between spin speed and lot in the variance analysis must
be greater than or equal to 0.1. If the ``P'' value is less than
0.1, the test cloth is unacceptable. ``P'' is a theoretically based
measure of interaction based on an analysis of variance.
7. Application of the RMC Correction Curve
7.1 Using the coefficients A and B calculated in section 6.1 of
this appendix:
RMCcorr = A x RMC + B
7.2 Apply this RMC correction curve to measured RMC values in
appendix J1 and appendix J2.
