as that published in: (1) DOE’s notice of
proposed rulemaking (NOPR) to amend
the test procedure for residential clothes
washers, published in September 2010
(75 FR 57556, Sept. 21, 2010)
(September 2010 NOPR); and (2) DOE’s
recent SNOPR to address the
incorporation of certain provisions of
IEC 62301 (Second Edition) into the test
procedure (76 FR 49238, Aug. 9, 2011)

September 2010 NOPR and August 2011
SNOPR for further details.
II. Summary of the Supplemental
Notice of Proposed Rulemaking
The revised clothes washer test
procedure amendments DOE is
proposing in today’s SNOPR would
update the definition of the energy test
cycle. The proposed definition would
apply to the revised test procedure to be
published at appendix J2 at 10 CFR 430
subpart B. At the end of this SNOPR,
DOE sets forth the proposed regulatory
text from DOE’s proposed test procedure
amendments in the September 2010
NOPR, as amended by the August 2011
SNOPR and today’s proposals.
Today’s SNOPR covers only the
energy test cycle definition. DOE will
discuss all other aspects of the proposed
test procedure revisions, and respond to
comments received from interested
parties on those aspects of the proposed
revisions, in the final rule.
III. Discussion
A. Today’s Proposed Revision for Part
(B) of the Energy Test Cycle
Based on the discussion of comments
in the following sections, DOE proposes
in today’s SNOPR to modify the
definition of the energy test cycle as
follows:
Energy test cycle for a basic model means:
(A) The cycle setting recommended by the
manufacturer for washing cotton or linen
clothes, and includes all wash/rinse
temperature selections offered in that cycle
setting, and
(B) if the cycle setting described in (A)
does not include all wash/rinse temperature
combinations available on the clothes
E:\FR\FM\09NOP2.SGM
09NOP2
Federal Register / Vol. 76, No. 217 / Wednesday, November 9, 2011 / Proposed Rules
washer, the energy test cycle shall also
include the alternate cycle setting(s) offering
these wash/rinse temperature combination(s),
tested at the wash/rinse temperature
combinations not available on the cycle
setting described in (A).
Where multiple alternate cycle settings
offer a wash/rinse temperature combination
that is not available on the cycle setting
recommended by the manufacturer for
washing cotton or linen clothes, the cycle
setting certified by the manufacturer to have
the highest energy consumption, as measured
according to section 2.13, shall be included
in the energy test cycle.
(C) All cycle settings included under part
(A) and part (B) shall be tested using each
appropriate load size as defined in section
2.8 and Table 5.1.
(D) For any cycle setting tested under (A)
or (B), the manufacturer default settings shall
be used, except for the temperature selection,
if necessary. This includes wash conditions
such as agitation/tumble operation, soil level,
spin speed(s), wash times, rinse times, and
all other wash parameters or optional
features applicable to that cycle, including
water heating time for water heating clothes
washers. Each wash cycle included as part of
the energy test cycle shall comprise the entire
active washing mode and exclude any delay
start or cycle finished modes.
jlentini on DSK4TPTVN1PROD with PROPOSALS2
DOE also proposes to add a new
section 2.13 to the revised test
procedure as follows:
2.13 Energy Consumption for the
Purpose of Certifying the Cycle
Setting(s) To Be Included in Part (B) of
the Energy Test Cycle Definition
Where multiple alternate cycle
settings offer a wash/rinse temperature
combination not available on the cycle
setting recommended by the
manufacturer for washing cotton or
linen clothes, the cycle setting with the
highest energy consumption, as
measured according to this section,
shall be included in the energy test
cycle.
To determine which cycle setting has
the highest energy consumption,
establish the testing conditions set forth
in section 2 of this test procedure. Select
the applicable cycle setting and
temperature combination. Use the
manufacturer default settings for
agitation/tumble operation, soil level,
spin speed(s), wash times, rinse times,
and all other wash parameters or
optional features applicable to that
cycle, including water heating time for
water heating clothes washers. Each
wash cycle tested under this section
shall comprise the entire active washing
mode and exclude any delay start or
cycle finished modes.
To identify the cycle setting with the
highest energy consumption, use the
clothes washer’s maximum test load
size, determined from Table 5.1. For
clothes washers with a manual water fill
VerDate Mar<15>2010
18:28 Nov 08, 2011
Jkt 226001
control system, user-adjustable adaptive
water fill control system, or adaptive
water fill control system with alternate
manual water fill control system, use
the water fill selector setting resulting in
the maximum water level available for
each cycle setting.
Measure each cycle setting’s electrical
energy consumption (EB) and hot water
consumption (HB). Calculate the total
energy consumption for each cycle
setting (ETB), as follows:
ETB = EB + (HB x T x K)
Where:
EB is the electrical energy consumption,
expressed in kilowatt-hours per cycle.
HB is the hot water consumption, expressed
in gallons per cycle.
T = temperature rise = 75 °F (41.7 °C)
K = Water specific heat in kilowatt-hours per
gallon per degree F = 0.00240 (0.00114
kWh/L-°C)
The provisions proposed in today’s
rule would be set forth in appendix J2
and would become effective 30 days
after the date of publication in the
Federal Register of the final rule in this
test procedure rulemaking. DOE would
clarify in the published amended test
procedures, however, that
manufacturers would be required to use
amended appendix J1 until the
compliance date of any final rule
establishing amended energy
conservation standards that addresses
standby and off mode power
consumption for these products. 42
U.S.C. 6295(gg)(2)(C). At such time,
manufacturers would begin using the
test procedures in appendix J2. DOE
notes that until use of appendix J2 is
required, DOE’s guidance on warm rinse
and capacity measurement, available at
https://www1.eere.energy.gov/buildings/
appliance_standards/residential/
clothes_washers.html, is still applicable.
B. Discussion of Energy Test Cycle

SNOPR that resulted in the proposal
stated in section III.A.
1. Background
The ‘‘energy test cycle’’ comprises all
the wash/rinse temperature selections
currently used in determining the
modified energy factor (MEF) and water
factor (WF) for a clothes washer, and
proposed to be used for determining
integrated modified energy factor
(IMEF) and integrated water
consumption factor (IWF). The energy
test cycle is defined in section 1.7 of the
current clothes washer test procedure as
follows:
1.7 Energy test cycle for a basic model
means (A) The cycle recommended by the
manufacturer for washing cotton or linen
clothes, and includes 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. Any
cycle under (A) or (B) shall include the
agitation/tumble operation, spin speed(s),
wash times, and rinse times applicable to
that cycle, including water heating time for
water heating clothes washers.
10 CFR Part 430, Subpart B, Appendix
J1
The cycle setting recommended for
washing cotton or linen clothes is
commonly referred to as the ‘‘Normal’’
setting. DOE has observed that on
clothes washers with electronic control
panels, certain wash/rinse temperature
combinations are commonly ‘‘locked
out’’ of the Normal setting. In such
cases, these wash/rinse temperatures
can be accessed only by switching the
control panel selection dial to one of the
other settings (e.g. ‘‘Whites’’, ‘‘Heavy
Duty’’, ‘‘Casual’’, ‘‘Permanent Press’’,
etc.). DOE has observed that the extrahot wash/cold rinse and/or warm wash/
warm rinse temperature combinations
are locked out of the Normal setting on
some clothes washer models that offer
such selections.
In cases where certain wash/rinse
combinations are locked out of the
Normal setting, manufacturers may test
only the temperature selections
available on the Normal setting, despite
being able to access other wash/rinse
temperature selections on other settings.
Testing only the wash temperature
selections available in the Normal
setting may neglect part (B) of the
energy test cycle definition, which
requires manufacturers to switch out of
the Normal setting to a different setting
that allows the other temperature
E:\FR\FM\09NOP2.SGM
09NOP2
69872
Federal Register / Vol. 76, No. 217 / Wednesday, November 9, 2011 / Proposed Rules
combinations to be selected and tested,
if such testing ‘‘will contribute to an
accurate representation of energy
consumption as used by consumers.’’
Because the temperature selections
typically locked out of the Normal
setting are those that use greater
quantities of hot water and thus have
higher water heating energy
consumption, excluding them from the
energy test cycle could increase a
clothes washer’s MEF, while not
accurately representing the energy
consumption of a particular machine as
used by the consumer.
2. September 2010 NOPR Proposal and
Comments Received
In the September 2010 NOPR, DOE
noted that the specific language
requiring manufacturers to test different
temperature selections if such testing
‘‘contribute[s] to an accurate
representation of energy consumption as
used by consumers’’ has caused some
confusion and differences in
interpretation among manufacturers and
independent test laboratories. DOE
believes the energy test cycle definition
must be clear, uniformly understood,
and able to be interpreted consistently
by manufacturers, competitors, and
independent test laboratories without
subjective judgment or reliance on
proprietary data.
In the September 2010 NOPR, DOE
proposed to amend part (B) of the
energy test cycle definition to provide
clarity in determining whether to test
temperature selections that are available
on the clothes washer but locked out of
the Normal setting. Specifically, DOE
proposed modifying part (B) as follows:
jlentini on DSK4TPTVN1PROD with PROPOSALS2
‘‘* * * (B) if the cycle described in (A)
Does not include all wash/rinse temperature
settings available on the clothes washer and
required for testing as described in this test
procedure, the energy test cycle shall also
include the portions of a cycle setting
offering these wash/rinse temperature
settings with agitation/tumble operation, spin
speed(s), wash times, and rinse times that are
largely comparable to those for the cycle
recommended by the manufacturer for
washing cotton or linen clothes. Any cycle
under (A) or (B) shall include the default
agitation/tumble operation, soil level, spin
speed(s), wash times, and rinse times
applicable to that cycle, including water
heating time for water heating clothes
washers.’’ 75 FR 57556, 57575–76 (Sept. 21,
2010).
The Association of Home Appliance
Manufacturers (AHAM) commented that
DOE’s proposal in the September 2010
NOPR to amend part (B) of the energy
test cycle definition was vague,
undefined, and included a significant
amount of variability. AHAM noted that
variability in a test procedure has
VerDate Mar<15>2010
18:28 Nov 08, 2011
Jkt 226001
substantial consequences for
manufacturers, and that the test
procedure must be clear and be
uniformly understood to avoid
significant variations in testing across
laboratories or technicians. (AHAM, No.
14 at p. 15) 1
Alliance Laundry Systems (ALS)
commented that DOE’s proposal is
vague and the proposal would require
applying consumer usage factors to all
available settings other than the Normal
setting. ALS believes that different
certification test laboratories could not
apply part (B) in any meaningful and
consistent manner. Further, ALS
believes the burden on manufacturers
and test laboratories to try to utilize part
(B) would be significant and likely
unbearable. (ALS, No. 10 at p. 5)
Whirlpool Corporation (Whirlpool)
commented that the term ‘‘largely
comparable’’ in the proposed part (B)
definition is not clear and is open to the
same type of interpretation and
confusion that currently exists, and
strongly urged DOE to revise its
proposed definition. (Whirlpool, No. 13
at p. 13)
BSH Home Appliances (BSH)
commented that, while it generally
agrees with the proposal to measure a
complete warm wash/warm rinse cycle,
the problems suggested by DOE that
prompted the proposed revision of part
(B) would return with the proposed
wording of the energy test cycle
definition. BSH stated that numerous
portions of cycles without defined start
and end points would need to be
incorporated into energy data
depending on the interpretation of the
words ‘‘largely comparable.’’ According
to BSH, assembling portions of cycles to
test under part (B) would not represent
a cycle setting that a consumer could
ever select, and thus would not be
representative of actual consumer usage.
(BSH, No. 20 at p. 4; BSH, Public
Meeting Transcript, No. 20 at pp. 188–
189) BSH further stated that it opposes
the proposed definition of the energy
test cycle for the following reasons: (1)
The proposed definition would lead to
questions about which of the ‘‘largely
comparable’’ cycle settings is the ‘‘worst
case’’ (e.g., the cycle setting with the
highest energy consumption but not the
highest water consumption, the cycle
setting with the highest water
consumption but not the highest energy
consumption, etcetera); (2) the
uncertainty in interpreting the phrase

docket of the clothes washer test procedure

‘‘contributes to an accurate
representation of the energy
consumption’’ would be replaced with
similar uncertainty in interpreting the
phrase ‘‘largely comparable.’’
Accordingly, BSH questioned what
threshold criteria would be used to
determine whether a setting is close
enough to the Normal setting to be
considered comparable. BSH believes
that the proposed definition could lead
to every cycle setting having to be
measured, with ‘‘largely comparable’’
being interpreted differently by
manufacturers, certification bodies, and
verification bodies. (BSH, No. 13 at p. 5;
BSH, Public Meeting Transcript. No. 20
at pp. 188, 190, 193)
GE Appliances & Lighting (GE) agreed
with AHAM’s comments and offered an
alternative definition for the energy test
cycle, as follows:
Energy test cycle for a basic model means
(A) The cycle recommended by the
manufacturer for washing cotton or linen
clothes, and includes all wash/rinse
temperature selections and water levels
offered in that cycle; and (B) If the cycle
described in (A) does not include all wash/
rinse temperature selections available on the
clothes washer, and these selections are
required for testing as described in this test
procedure, then the energy test cycle shall
include the other cycles available on the
clothes washer tested only at the wash/rinse
temperature selections which are not
available on the cycle described in (A). If a
wash/rinse temperature selection not
available in the cycle described in (A) is
available on multiple other cycles provided
on the clothes washer, then each cycle with
that wash/rinse temperature selection must
be tested and the cycle resulting in the most
energy usage will be included in the energy
test cycle.’’ (GE, No. 15 at pp. 1–2)
GE expressed concern that the
proposed definition supplied in the
September 2010 NOPR may result in
different interpretations of what should
be included in the energy test cycle.
Specifically, GE commented that the
interpretation of what would be
considered ‘‘largely comparable to a
cottons or linens cycle’’ could be
variable and affect the results of an
energy test. GE stated that its proposed
definition would clarify the definition
and remove as much interpretation as
possible. (GE, No. 15 at pp. 1–2)
Springboard Engineering
(Springboard) interpreted the proposed
definition in part (B) as requiring the
warm wash/warm rinse temperature
combination to be tested, but questioned
whether the proposed definition
provides enough direction such that
different test laboratories would select
similar cycle settings on the same
clothes washer. Springboard noted, for
example, that some clothes washers
E:\FR\FM\09NOP2.SGM
09NOP2
Federal Register / Vol. 76, No. 217 / Wednesday, November 9, 2011 / Proposed Rules
jlentini on DSK4TPTVN1PROD with PROPOSALS2
have three or more warm wash/warm
rinse settings to choose among, and
different laboratories might use different
criteria to select which setting to
include in the energy test cycle.
Springboard stated that it would choose
the cycle setting similar in time and
agitation to the Normal setting;
however, Springboard noted that the
possibility that one laboratory could
select the ‘‘Colors’’ setting, for example,
while another might select the
‘‘Permanent Press’’ setting, which could
produce different measured
performance. According to Springboard,
different settings may not have the same
wash and rinse temperatures or spin
speeds, but such information would not
be known without first testing each
setting on the clothes washer and
comparing the hot water usage.
Springboard believes that these tests
could increase the test burden.
(Springboard, No. 11 at pp. 1–2)
Springboard also noted that the different
warm wash/warm rinse settings on a
clothes washer may have different spin
speeds, which will affect the remaining
moisture content (RMC) and MEF
calculation. Id. Furthermore,
Springboard commented that some
laboratories may interpret that a
‘‘Sanitize’’ setting with extra-hot wash
would not have to be tested because it
is not comparable to the Normal setting.
Springboard questioned whether the
intention of part (B) is to test the extrahot wash temperature combination,
even if it has to be selected with a
different setting such as the ‘‘Sanitize’’
setting. (Springboard, No. 11 at p. 2)
The Northwest Energy Efficiency
Alliance (NEEA) supports DOE’s
proposal to account for temperature
options available outside the ‘‘Normal’’
setting. NEEA believes DOE clarified
this provision in the proposed language
change for part (B) of the energy test
cycle. (NEEA, No. 12 at p. 14)
3. August 2011 SNOPR Proposal and
Comments Received
In testing conducted since the
September 2010 NOPR, DOE observed
that some clothes washers retain in
memory the most recent options
selected for a cycle setting the next time
that cycle is run. To ensure repeatability
of test results, particularly for cycles
under part (B) of the energy test cycle
definition, DOE proposed in the August
2011 SNOPR to further clarify that the
manufacturer default conditions for
each cycle setting shall be used, except
for the temperature selection, if
necessary. For example, if the extra-hot
temperature selection was only
available on the ‘‘Whites’’ setting, the
manufacturer would use the Whites
VerDate Mar<15>2010
18:28 Nov 08, 2011
Jkt 226001
setting to test that temperature option. If
the default wash temperature for the
Whites setting was warm or hot,
however, the manufacturer would have
to manually adjust the temperature to
obtain the extra-hot wash temperature.
For certification testing in this
illustrative case, the manufacturer
would use the default settings on the
Whites setting for all options except the
temperature selection, which would be
manually adjusted to achieve the
desired temperature.
In addition, DOE proposed in the
August 2011 SNOPR to delete the
phrase, ‘‘and required for testing as
described in this test procedure’’ from
part (B) as redundant and unnecessary.
In response to the revised proposal in
the August 2011 SNOPR, AHAM stated
that it opposes including the phrase,
‘‘the manufacturer default settings for
each cycle setting shall be used, except
for the temperature selection’’ in the
energy test cycle definition. AHAM
believes the proposed clarification is
vague because it is open to
interpretation by manufacturers.
(AHAM, No. 24 at p. 5) AHAM further
stated generally that the proposed
clarification to the energy test cycle
definition, as well as the existing part
(B) of the definition, represent
significant test burden with no
corresponding benefit because the
results are not representative of actual
consumer use. (AHAM, No. 24 at p. 5)
ALS opposed the proposed
clarification to part (B) of the energy test
cycle definition, stating that the phrase
‘‘largely comparable’’ is vague and open
to interpretation. (ALS, No. 22 at p. 2)
ALS proposed eliminating part (B) of
the energy test cycle definition entirely,
due to the test burden associated with
measuring energy use in every possible
cycle option. ALS proposed
implementing only part (A) of the
energy test cycle definition, which is
‘‘the cycle recommended by the
manufacturer for washing cotton or
linen clothes, and includes all the wash/
rinse temperature selections and water
levels offered in that cycle.’’ (ALS, No.
22 at p. 2) ALS supports DOE’s proposal
to clarify that the manufacturer’s default
settings be utilized in the energy test
cycle definition. (ALS, No. 22 at p. 2)
Whirlpool disagreed with part (B) of
the energy test cycle definition as
proposed in the August 2011 SNOPR.
Whirlpool stated that part (B) would
require including temperature/water
level options not recommended by the
manufacturer for washing cotton and
linen clothing because they may lead to
clothing damage such as shrinkage, dye
transfer, puckering, or other outcomes
unacceptable to the consumer.
PO 00000
Frm 00005
Fmt 4701
Sfmt 4702
69873
(Whirlpool, No. 27 at p. 2) Whirlpool
stated that it possesses proprietary
consumer data suggesting that steam
and Sanitize cycle settings are used
infrequently, warranting their exclusion
from the energy test cycle definition.
(Whirlpool, No. 27 at p. 2) Whirlpool
proposes the following definition for the
energy test cycle:
‘‘Energy test cycle for a basic model means
the cycle recommended by the manufacturer
for washing cotton or linen clothes, and
includes all wash/rinse temperature
selections and water levels offered in that
cycle. If a particular wash/rinse temperature
selection or water level is available on the
basic model, but is not available for selection
in the cycle recommended by the
manufacturer for washing cotton or linen
clothes (i.e., is locked out of the cycle), then
that temperature selection and/or water level
shall not be included in the energy test
cycle.’’ (Whirlpool, No. 27 at p. 2).
Whirlpool, ALS, and GE (hereafter
referred to as the ‘‘Joint Manufacturers’’)
submitted a joint comment on the
August 2011 SNOPR. The Joint
Manufacturers agree with AHAM that
DOE’s proposed amendment to part (B)
in the August 2011 SNOPR is vague
because it is open to a significant
amount of interpretation by
manufacturers. (Joint Manufacturers,
No. 28 at p. 1) The Joint Manufacturers
further agree with AHAM that the cycle
setting recommended for washing
cotton or linen clothes is the cycle
setting that is most representative of
consumer use, and if the consumer
cannot select a temperature for that
cycle setting, then it is not
representative to arbitrarily select other
settings that have that temperature
option. The Joint Manufacturers stated
that requiring arbitrary selection of
temperatures adds ambiguity to the test
procedure, which results in variability.
The Joint Manufacturers urged DOE to
eliminate part (B) from the proposed
definition of the energy test cycle. Id.
The Joint Manufacturers further stated
that if DOE nevertheless decides to
retain part (B) of the energy test cycle
definition, the following revised
language should be used for part (B):
‘‘* * * (B) if the cycle described in (A)
does not include a water heating option and
the clothes washer has a water heating
temperature selection or cycle available, the
cycle and temperature selection
recommended by the manufacturer for
sanitization, disinfection or similar must be
included in the energy test cycle. In the case
of multiple such cycles, the cycle using the
most energy at the manufacturer default
setting must be chosen. If the clothes washer
has a water heating option and the
manufacturer does not recommend a cycle
for sanitization, disinfection, or similar, the
energy test cycle shall include the water

heating cycle and temperature selection with
the manufacturer’s default cycle time. Again,
in the case of multiple such cycles the cycle
using the most energy at the manufacturer
default setting must be chosen. Any cycle
under (A) or (B) shall include the
manufacturer’s default agitation/tumble
operation, soil level, spin speeds, wash
times, and rinse times applicable to that
cycle, including water heating time for water
heating clothes washers.’’ (Joint
Manufacturers, No. 28 at pp. 1–2; Whirlpool,
No. 27 at pp. 2–3).
jlentini on DSK4TPTVN1PROD with PROPOSALS2
NEEA agrees with DOE’s proposed
changes to the energy test cycle
definition. However, NEEA believes that
the point at which the test cycle starts
and ends is not defined in the clothes
washer test procedure. (NEEA, No. 26 at
p. 4) NEEA questioned whether the
beginning of the energy test cycle could
be defined as the beginning of the
delayed wash cycle, if any; and whether
the end of the energy test cycle could be
defined as the beginning of the
‘‘inactive’’ mode. (NEEA, No. 26 at p. 4)
NEEA stated that defining the energy
test cycle as starting with the activation
of the ‘‘delay start’’ mode, if any (with
the duration specified) and ending with
the beginning of the inactive mode (with
the duration of the ‘‘cycle finished’’
mode, if any, specified, either in
minutes or number of cycles, or both),
would simplify and clarify the test
procedure. NEEA believes that while
this could lengthen the energy test cycle
itself, a greater amount of testing time
could be saved by not having to set up
and measure the ‘‘delay start’’ and
‘‘cycle finished’’ modes separately.
(NEEA, No. 26 at p. 4).
4. DOE Response to All Comments
As outlined in the previous sections,
the comments DOE received from
interested parties collectively identify
seven concerns related to its proposed
energy test cycle definition:
(1) Vague language. The proposed
definition is vague and would lead to
significant variability in interpretation;
particularly the phrase ‘‘largely
comparable.’’
(2) Elimination of part (B). Including
part (B) may not provide benefit to the
public interest and should be eliminated
entirely.
(3) Representativeness. The cycles
required to be tested under the proposed
part (B) are not representative of typical
consumer usage patterns.
(4) Test burden. Third party
laboratories could be required to test
numerous alternate cycle settings to
determine which cycles are largely
comparable to the normal cycle, which
could significantly increase test burden.
(5) Manufacturer default settings. The
energy test cycle definition should
VerDate Mar<15>2010
18:28 Nov 08, 2011
Jkt 226001
clearly specify whether the
manufacturer default settings should be
used, and if so, should clarify which
default settings to use.
(6) Suggested alternative definitions.
Interested parties suggested several
alternatives for defining the energy test
cycle.
(7) Definition of the start and end of
each cycle. The energy test cycle
definition should clearly define what
constitutes the start and end of each
active wash cycle.
The following sections provide DOE’s
responses to each of these issues.
a. Vague Language
Interested parties generally
commented that DOE’s proposed change
to part (B) of the energy test cycle
definition would create just as much
confusion as the current definition.
Specifically, interested parties believe
that the proposed definition does not
provide clear enough guidance on how
to determine whether a cycle setting is
‘‘largely comparable’’ to the Normal
setting, which would lead to significant
variability in interpretation and test
results.
DOE intended the proposed definition
to specify that the determination of
whether to include a cycle setting under
part (B) of the energy test cycle should
be made by comparing the agitation/
tumble operation, spin speeds, wash
times, and rinse times to those of the
Normal setting. DOE acknowledges,
however, that the proposed definition
does not clearly define the boundaries
of term ‘‘largely comparable,’’ leaving
this determination to the subjective
judgment of the test laboratory.
As stated earlier, DOE believes the
energy test cycle definition must be
clear, uniformly understood, and able to
be interpreted consistently by
manufacturers, competitors, and
independent test laboratories without
subjective judgment or reliance on
proprietary data. DOE notes that under
the alternative definitions proposed by
the Joint Manufacturers, the
determination of which cycle settings to
include under part (B) would be based
on an objective numerical criterion
readily determined by any test
laboratory: The cycle setting using the
most energy.
DOE recognizes that there are other
possible numerical criteria for
determining whether a cycle setting
should be included in the energy test
cycle under part (B) of the definition,
including the cycle setting using the
least energy, the cycle setting with
energy consumption most similar to that
of the Normal setting, or cycle settings
PO 00000
Frm 00006
Fmt 4701
Sfmt 4702
above or below a certain energy
consumption threshold.
DOE proposes, however, that
including the cycle setting that uses the
most energy would be the most
appropriate, objective criterion for
determining which cycle setting should
be included under part (B) of the energy
test cycle. This approach would ensure
that clothes washers requiring testing
under part (B) of the energy test cycle
meet the applicable energy conservation
standard when the maximum energy
consumption representative of average
consumer use is tested. This approach
would also provide clarity by requiring
only a single variable to be considered
to make the determination. Therefore,
DOE proposes in today’s SNOPR that for
each wash/rinse temperature
combination not available under the
Normal setting, the alternate cycle
setting that uses the most energy must
be chosen in the case where multiple
alternate cycle settings offer that wash/
rinse temperature combination.
DOE notes that this criterion requires
a clear definition of which components
of energy consumption should be
included in the measurement of each
cycle setting’s energy consumption—e.g.
electrical energy, hot water energy,
energy required for moisture removal
(i.e., dryer energy), or a combination of
these three energy components. DOE
proposes that the machine electrical
energy be included because this is a
direct measure of a form of energy
consumption by the clothes washer.
DOE also proposes that the hot water
energy be included for the following
reasons: (1) Water temperature is the
key characteristic that determines the
need for testing under part (B) of the
energy test cycle definition; (2) water
temperature is often one of the primary
parameters that consumers consider
when selecting a wash/rinse cycle; (3)
water heating energy represents a
significant portion of a cycle’s total
energy consumption; (4) the test
procedure already requires measuring
hot water consumption for each tested
cycle; and (5) a simple equation can be
used to translate hot water quantity into
hot water heating energy.
DOE does not propose to include the
drying energy in the determination of
which cycle settings should be tested
under part (B) of the energy test cycle.
DOE lacks information on whether an
RMC value that would be measured in
alternate cycle settings would be
comparable or analogous to the current
RMC metric from which drying energy
is calculated. Currently, RMC is
determined for a clothes washer based
on the results of only the cold wash/
cold rinse cycle and the warm wash/
E:\FR\FM\09NOP2.SGM
09NOP2
jlentini on DSK4TPTVN1PROD with PROPOSALS2
Federal Register / Vol. 76, No. 217 / Wednesday, November 9, 2011 / Proposed Rules
warm rinse cycle (if available), at
minimum and maximum spin speeds (if
available), using the maximum load
size. Depending on the clothes washer,
this corresponds to between one and
four dedicated RMC tests and could
significantly increase the test burden if
required to be performed for each
alternate cycle setting. The weightedaverage value obtained from these RMC
tests is calculated and considered to be
the average RMC value for the clothes
washer, across all cycles. Requiring the
measurement of RMC for the individual
cycles comprising the energy test cycle
would be inconsistent with this
methodology. Determining the energy
required for moisture removal would
require weighing the test cloth before
and after each cycle to determine its
remaining moisture content, which
would also impose additional test
burden. DOE further believes that in
many circumstances, consumers may
not be aware of variations in spin speed
if that information is not displayed on
the front panel of the clothes washer.
For these reasons, DOE does not
believe that the drying energy should be
included in determining whether a
cycle setting should be tested under part
(B) of the energy test cycle. Therefore,
DOE proposes in today’s SNOPR to
include the machine electrical energy
consumption and hot water energy
consumption when determining each
cycle setting’s total energy
consumption, in the identification of the
cycle setting that uses the most energy
for each wash/rinse temperature
combination to be tested under part (B)
of the energy test cycle.
Further, DOE notes that in sections
4.1.3 and 4.1.6 of the current test
procedure, machine electrical energy
and hot water energy are calculated as
the weighted averages of each tested
load size. Requiring the testing of
multiple load sizes for the purpose of
determining which cycle setting to
select for part (B) of the energy test
cycle, however, would unduly increase
the test burden. Therefore, DOE
proposes in today’s SNOPR to require
testing only the clothes washer’s
maximum load size, determined from
Table 5.1, for the purpose of comparing
the energy consumption of the alternate
cycle settings considered under part (B)
of the energy test cycle. Using the
maximum load size will produce the
most consistent, repeatable, and
conservative results.
In addition, DOE notes inconsistent
usage of the word ‘‘cycle’’ in the energy
test cycle definition. In some instances,
the word ‘‘cycle’’ refers to the labeled
program setting on the clothes washer
(e.g. ‘‘Normal’’, ‘‘Whites’’, ‘‘Colors’’,
VerDate Mar<15>2010
18:28 Nov 08, 2011
Jkt 226001
etc.). In other instances, the word
‘‘cycle’’ refers to an individual wash/
rinse cycle performed during active
wash mode (e.g. a cold wash/cold rinse
cycle). To help reduce this ambiguity,
DOE proposes in today’s SNOPR to
modify the nomenclature by using the
term ‘‘cycle setting’’ to indicate the
labeled program setting on the clothes
washer, and the term ‘‘cycle’’ to indicate
an individual wash/rinse cycle.
b. Elimination of Part (B)
As described in previous sections,
manufacturers and AHAM commented
that DOE should eliminate part (B) of
the energy test cycle definition, while
NEEA supports keeping part (B) to
account for temperature options
available outside the Normal setting.
Wash/rinse temperature combinations
locked out of the Normal setting should
also be included in the energy test cycle,
and doing so is representative of average
consumer use according to the
temperature use factors (TUFs) in the
test procedure. DOE is unaware of any
publicly available data indicating the
frequency with which consumers select
the Normal setting versus other cycle
settings. However, DOE notes that the
TUFs in the test procedure were
developed to represent consumer
selection of different temperature
options available on a clothes washer.
Each TUF represents the frequency with
which consumers select a particular
temperature option on machines
offering that temperature option. The
TUFs do not represent the frequency
with which consumers select a
particular temperature option among all
clothes washers on the market. For
example, if a particular clothes washer
offers a warm rinse option, the warm
rinse TUF indicates that the typical
consumer using that clothes washer will
select the warm rinse option for 27
percent of all wash loads. DOE believes
that the energy test cycle proposed in
section III.A, which requires use of part
(B) of the definition if part (A) does not
include all wash/rinse temperature
combinations available on the machine,
should include any temperature
combination for which a TUF has been
developed.
If part (B) of the energy test cycle were
to be eliminated, only the temperature
options available in the Normal setting
would be required for testing. Under
this scenario, if one clothes washer
offered all available temperature options
in the Normal setting, while a second
clothes washer offered the same
temperature options but with a subset of
those temperatures locked out of the
Normal setting, the locked out
temperature options on the second
PO 00000
Frm 00007
Fmt 4701
Sfmt 4702
69875
clothes washer would not be factored
into its energy efficiency rating. This
would imply that consumer behavior
would differ for these two clothes
washers; i.e., that consumers would
select the locked out temperature
combinations less frequently on the
second machine. DOE is not aware of
any data that quantifies how consumers
may adjust their behavior based on the
cycle setting for which a particular
temperature option is available (e.g.
‘‘Normal’’, ‘‘Whites’’, ‘‘Colors’’, etc.)
rather than on the desired temperature
option itself.
In addition, if DOE eliminated part (B)
from the energy test cycle definition,
manufacturers could arbitrarily exclude
temperatures from the Normal setting,
thus excluding them from being tested
under the DOE test procedure. In the
most extreme case, a manufacturer
could create a Normal setting that offers
only cold water temperatures, and move
all heated water cycles to alternate cycle
settings on the machine. In this case,
consumers would likely select the
alternate cycle settings for a significant
portion of wash cycles, yet only the cold
cycle would be required for testing
under the DOE test procedure.
In summary, DOE believes that if a
temperature combination is ‘‘locked
out’’ of the Normal cycle setting but
exists on at least one alternate cycle
setting, it should be included in the
energy test cycle under the assumption
that a consumer will switch to one of
the alternate cycles to obtain that wash/
rinse temperature combination. For the
reasons stated above, DOE proposes in
today’s SNOPR to keep part (B) of the
energy test cycle definition, and to
require testing of all temperature
combinations available on the machine,
including any temperature options
locked out of the Normal setting.
c. Representativeness
Manufacturers and AHAM expressed
concern that the wash cycles, or
portions of wash cycles, required to be
tested under part (B) are not
representative of consumer usage
patterns. As described in the previous
section, DOE does not have data to
verify how consumers may adjust their
behavior based on the particular cycle
setting for which a temperature option
is available, rather than the desired
temperature option itself.
DOE acknowledges that the wording
of part (B) in the current test procedure
and DOE’s proposals in the September
2010 NOPR and August 2011 SNOPR
include language referring to ‘‘portion(s)
of other cycle(s) with that temperature
selection or water level * * *’’ that may
be interpreted in different ways. DOE
E:\FR\FM\09NOP2.SGM
09NOP2
69876
Federal Register / Vol. 76, No. 217 / Wednesday, November 9, 2011 / Proposed Rules
jlentini on DSK4TPTVN1PROD with PROPOSALS2
does not believe that the energy test
cycle should include portions of
individual wash cycles. DOE concurs
with BSH that assembling portions of
cycles to test under part (B) (i.e. testing
the wash portion of one cycle in
combination with the rinse portion of
another cycle) would not represent a
cycle that a consumer could select, and
thus would not be representative of
actual consumer usage. As a result, the
energy test cycle should include only
complete wash/rinse cycles as
programmed on the clothes washer.
Accordingly, DOE proposes in today’s
SNOPR to remove the phrase ‘‘portion(s)
of other cycles’’ from the definition of
energy test cycle.
d. Test Burden
DOE acknowledges that the language
it proposed in the September 2010
NOPR and August 2011 SNOPR for part
(B) of the energy test cycle could
significantly increase test burden if a
laboratory is required to test numerous
alternate cycle settings to determine
which cycles are largely comparable to
the normal cycle. Under today’s
proposal, manufacturers would test all
wash/rinse temperature combinations
not available under part (A) of the
energy test cycle definition. Where
multiple cycle settings offer these wash/
rinse temperature combinations, DOE
proposes a clear, objective way for
manufacturers to determine of which
cycle(s) to include in the energy test
cycle. DOE proposes that for each of
these wash/rinse temperature
combinations, manufacturers include
the cycle setting that uses the most
energy in the energy test cycle. DOE
further proposes to require
manufacturers to certify to DOE the
specific cycle settings comprising the
energy test cycle for each basic model of
its clothes washer. This list of cycle
settings would be provided to DOE and
any test laboratory used by the
manufacturer or DOE, so that neither
DOE nor the test laboratory would be
required to independently determine
which cycles should be included. DOE
believes that this proposal would
eliminate a major source of ambiguity
and inconsistency of test results among
various laboratories.
This proposal would require a
manufacturer to provide to DOE as part
of its certification the cycle settings that
a manufacturer used to determine each
clothes washer’s energy efficiency
rating. Under DOE’s certification,
compliance, and enforcement program
in 10 CFR part 429, subpart C, DOE can
conduct assessment or enforcement
testing to determine whether the
manufacturer’s declared energy test
VerDate Mar<15>2010
18:28 Nov 08, 2011
Jkt 226001
cycles are those cycles for a particular
wash/rinse temperature combination
that use the most energy.
e. Manufacturer Default Settings
A typical clothes washer may allow
the consumer to adjust certain
parameters of a given cycle setting, such
as wash/rinse temperature, water fill
levels, soil level, agitation/tumble
operation, spin speed, wash time, rinse
time, and other optional features such as
delay start, cycle-finished activity,
steam injection, chemical dispensers,
and signal sounds. For any active wash
mode cycle included in the energy test
cycle, the default manufacturer settings
should be used for any parameter not
explicitly specified by the test
procedure because DOE is not aware of
any data quantifying how often
consumers select these optional features
or deviate from the default manufacturer
cycle settings. The test procedure
specifies wash/rinse temperatures and
water fill levels for all test cycles, and
spin speeds for the RMC test cycles.
DOE proposes in today’s SNOPR to
clarify in the definition of the energy
test cycle that for any cycle setting
tested under part (A) or (B), the
manufacturer default parameters shall
be used, except for the temperature
selection, if necessary.
f. Suggested Alternative Definitions
Several manufacturers suggested
alternate definitions for the energy test
cycle, including specific suggestions for
part (B), as described previously in
sections III.B.2 and III.B.3. In response
to the August 2011 SNOPR, the Joint
Manufacturers proposed language for
part (B) that would require testing the
extra-hot cycle on water heating clothes
washers. The proposal suggested that in
the case of multiple such cycles, the
cycle using the most energy at the
manufacturer default setting must be
chosen.
As described in the previous sections,
DOE proposes that a cycle setting’s
energy consumption be used to
determine whether that setting should
be included under part (B). However,
the definition proposed by the Joint
Manufacturers would require testing
only the extra-hot temperature setting
under part (B). Under this proposal, if
other wash/rinse temperature
combinations such as warm wash/warm
rinse or hot wash/cold rinse were also
locked out of the Normal setting, they
would not be required for testing. In
contrast, GE’s proposed definition for
part (B), submitted in response to the
September 2010 NOPR, as discussed
previously, would require testing all
wash/rinse temperature selections
PO 00000
Frm 00008
Fmt 4701
Sfmt 4702
available on the machine and not
included in the Normal setting.
DOE’s proposed definition of energy
test cycle would require testing of all
wash/rinse temperature combinations
available on the machine, not just the
extra-hot temperature setting, to ensure
that the definition is representative of
average consumer use. As stated
previously, DOE’s proposed definition
of energy test cycle would include any
temperature combination for which a
TUF has been developed. As stated
above, if a ‘‘locked out’’ temperature
combination exists on at least one
alternate cycle setting, a setting with
that temperature combination should be
included in the energy test cycle
because the TUFs indicate that a
consumer will switch to one of the
alternate settings to obtain that wash/
rinse temperature combination.
Therefore, DOE proposes in today’s
SNOPR to use the criteria suggested by
the Joint Manufacturers for determining
which cycle setting to choose under part
(B), and to use language suggested by GE
to require testing all wash/rinse
temperature combinations available on
the machine not included in the Normal
setting. DOE’s revised proposal for part
(B) of the energy test cycle definition is
set forth in section III.A.
g. Definition of the Start and End of
Each Cycle
As described previously, NEEA
commented that the energy test cycle
does not clearly define the start and end
of each wash cycle tested under the
energy test cycle. DOE has observed
through its own testing that delay start
and cycle finished features are typically
available as optional features which are
not activated by default. Thus, they
would not be activated during the
energy test cycle, and the start and
finish of each wash cycle would be
unambiguous. DOE acknowledges that
as delay start and cycle finished features
become more prevalent in the market,
however, clothes washers could be
manufactured that activate some of
these features by default during any of
the wash cycles comprising the energy
test cycle. Therefore, DOE proposes to
define the start and end of the energy
test cycle more clearly.
In the August 2011 SNOPR, DOE
proposed adding definitions for active
washing mode, delay start mode, and
cycle finished mode. DOE believes that
these three definitions can be used to
clarify the start and end of the energy
test cycle. DOE proposes in today’s
SNOPR to specify that each cycle
included as part of the energy test cycle
comprises the entire active washing
E:\FR\FM\09NOP2.SGM
09NOP2
Federal Register / Vol. 76, No. 217 / Wednesday, November 9, 2011 / Proposed Rules
mode, and excludes any delay start or
cycle finished modes.
C. Compliance With Other EPCA
Requirements
1. Test Burden
EPCA requires that any test
procedures prescribed or amended
under this section 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. Test
procedures must also not be unduly
burdensome to conduct.’’ (42 U.S.C.
6293(b)(3))
DOE determined that the proposed
test procedure amendments in the
September 2010 NOPR and August 2011
SNOPR satisfy these EPCA
requirements, as described in those
rulemaking documents. The proposals
in today’s SNOPR also satisfy these
requirements, as described in the
following paragraphs.
Commenters stated that the proposed
definition of energy test cycle in the
September 2010 NOPR and August 2011
SNOPR would be vague and could
significantly increase the testing burden.
Today’s proposal is intended to provide
a clear, objective definition of energy
test cycle and would require
manufacturers to certify to DOE the list
of cycle settings comprising the energy
test cycle for each basic model of its
clothes washers, so that testing
laboratories would know which cycles
to test. While the proposed definition of
the energy test cycle would require
testing additional wash cycles under
part (B) to determine which cycle
setting has the highest energy
consumption, the manufacturer already
possesses in-depth knowledge about the
energy characteristics of each wash/
rinse cycle offered on its clothes
washers. Other test laboratories would
not be required to conduct multiple
tests to determine which cycle settings
should be included under part (B) of the
energy test cycle. Therefore, compared
to the current test procedure, DOE
expects that today’s proposal could
reduce the test burden, because it would
remove the existing uncertainty as to
which cycle settings should be selected.

2. Commercial Clothes Washers
The test procedure for commercial
clothes washers is required to be the
same test procedure established for
residential clothes washers. (42 U.S.C.
6314(a)(8)) Thus, the test procedure set
forth in appendix J1 of subpart B of 10
CFR part 430 is also currently used to
test commercial clothes washers. (10
VerDate Mar<15>2010
18:28 Nov 08, 2011
Jkt 226001
CFR part 431.154) The definition of the
energy test cycle proposed in today’s
SNOPR could affect the measurement of
active mode energy use. DOE notes that
42 U.S.C. 6293(e)(3) provides that
models of covered products in use
before the date on which an amended
energy conservation standard
(developed using the amended test
procedure pursuant to 42 U.S.C.
6293(e)(2)) becomes effective that
comply with the energy conservation
standard applicable to such covered
products on the day before such date are
deemed to comply with the amended
standard. The same is true of revisions
of such models that come into use after
such date and have the same energy
efficiency, energy use or water use
characteristics.
IV. Procedural Issues and Regulatory
Review
The regulatory reviews conducted for
this proposed rule are identical to those
conducted for the August 2011 SNOPR.
An update to the Regulatory Flexibility
Act certification is set forth below.
Please see the August 2011 SNOPR for
further details.
Review Under the Regulatory Flexibility
Act
The Regulatory Flexibility Act (5
U.S.C. 601 et seq.) requires preparation
of an initial 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://
www.gc.doe.gov.
DOE reviewed today’s supplemental
proposed rule under the provisions of
the Regulatory Flexibility Act and the
procedures and policies published on
February 19, 2003. DOE tentatively
concluded that the September 2010
NOPR and August 2011 SNOPR would
not have a significant impact on a
substantial number of small entities,
and today’s SNOPR contains no
revisions to that proposal that would
result in a significant impact on a
substantial number of small entities.
PO 00000
Frm 00009
Fmt 4701
Sfmt 4702
69877
The factual basis for this certification is
as follows:
The Small Business Administration
(SBA) considers a business entity to be
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 North
American Industry Classification
System (NAICS). The threshold number
for NAICS classification code 335224,
which applies to household laundry
equipment manufacturers and includes
clothes washer manufacturers, is 1,000
employees. Searches of the SBA Web
site 2 to identify clothes washer
manufacturers within these NAICS
codes identified, out of approximately
17 manufacturers supplying clothes
washers in the United States, only one
small business. This small business
manufactures laundry appliances,
including clothes washers. The other
manufacturers supplying clothes
washers are large, multinational
corporations.
The proposed rule would amend
DOE’s test procedure by revising the
definition of energy test cycle to more
precisely define which cycles are
required for testing under part (B) of the
definition.
DOE believes these additional
requirements would not be expected to
impose a significant economic burden
on entities subject to the applicable
testing requirements. Today’s proposal
is intended to provide a clear, objective
definition of energy test cycle, which is
expected to reduce the testing burden.
The provisions in today’s SNOPR would
also require manufacturers to report to
DOE the cycle settings comprising the
complete energy test cycle for each basic
model. Manufacturers already possess
in-depth knowledge about the energy
characteristics of each wash/rinse cycle
offered on their clothes washers, so DOE
expects manufacturers to experience
little or no additional test burden due to
today’s proposed revisions.
For these reasons, DOE certifies that
if adopted, the September 2010 NOPR,
as modified by the August 2011 SNOPR
and today’s SNOPR, would not have a
significant economic impact on a
substantial number of small entities.
Accordingly, DOE has not prepared a
regulatory flexibility analysis for this
rulemaking. DOE has previously
transmitted the 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).

The revisions read as follows:
*
Appendix J1 to Subpart B of Part 430—
Uniform Test Method for Measuring the
Energy Consumption of Automatic and
Semi-Automatic Clothes Washers
Appendix J1 is effective until the
compliance date of any amended standards
that address standby and off mode power
consumption for residential clothes washers.
After this date, all residential clothes washers
shall be tested using the provisions of
Appendix J2.

*
*
*
*
1.22 Cold rinse means the coldest rinse
temperature available on the machine.
*
*
*
*
*
2.6.3.1 Perform 5 complete normal washrinse-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 lb 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 (total of five
wash and rinse cycles).
*
*
*
*
*
2.10 Wash time setting. If one wash time
is prescribed in the energy test cycle, 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 in the energy test cycle,
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

3.6 ‘‘Cold Wash’’ (Minimum Wash
Temperature Selection). Water and electrical
energy consumption shall be measured for
each water fill level or test load size as
specified in sections 3.6.1 through 3.6.3 of
this appendix for the coldest wash
temperature selection available. For a clothes
washer that offers two or more wash
temperature settings labeled as cold, such as
‘‘Cold’’ and ‘‘Tap Cold’’, the setting with the
minimum wash temperature shall be
considered the cold wash. If any of the other
cold wash temperature settings add hot water
to raise the wash temperature above the cold
water supply temperature, as defined in
section 2.3 of this appendix, those setting(s)
shall be considered warm wash setting(s), as
defined in section 1.18 of this appendix. If
none of the cold wash temperature settings
add hot water for any of the water fill levels
or test load sizes required for the energy test
cycle, the wash temperature setting labeled
as ‘‘Cold’’ shall be considered the cold wash,
and the other wash temperature setting(s)
labeled as cold shall not be required for
testing.

4.1.4 Total per-cycle hot water energy
consumption using gas-heated or oil-heated
water. Calculate for the energy test cycle the
per-cycle hot water consumption, HETG,
using gas-heated or oil-heated water,
expressed in Btu per cycle (or megajoules per
cycle) and defined as:
HETG = HET × 1/e × 3412 Btu/kWh or HETG
= HET × 1/e × 3.6 MJ/kWh
Where:

incorporate energy stuffer cloths to help
offset the size difference.
2.6.5.3.3 Soak the test load for 20 minutes
in 10 gallons of soft (< 17 ppm) water. The
entire test load shall be submerged. The
water temperature shall be 100 °F ± 5 °F (38
°C ± 3 °C)
2.6.5.3.4 Remove the test load and allow
each of the test cloth bundles to drain over
the water bath for a maximum of 5 seconds.
2.6.5.3.5 Manually place the test cloth
bundles in the basket of the extractor,
distributing them evenly by eye. The
draining and loading process should take less
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.
2.6.5.3.6 Record the weight of the test
load immediately after the completion of the
extractor spin cycle (WC).
2.6.5.3.7 Calculate the RMC as (WC–WI)/
WI.
2.6.5.3.8 It is not necessary to drain the
soak tub if the water bath is corrected for
water level and temperature before the next
extraction.

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 setting is
reached.
2.11 Test room temperature.
2.11.1 Non-water-heating clothes washer.
For combined low-power mode testing,

combination not available on the cycle
setting recommended by the manufacturer for
washing cotton or linen clothes, the cycle
setting with the highest energy consumption,
as measured according to this section, shall
be included in the energy test cycle.
To determine which cycle setting has the
highest energy consumption, establish the
testing conditions set forth in section 2 of
this test procedure. Select the applicable
cycle setting and temperature combination.
Use the manufacturer default settings for
agitation/tumble operation, soil level, spin
speed(s), wash times, rinse times, and all
other wash parameters or optional features
applicable to that cycle, including water
heating time for water heating clothes
washers. Each wash cycle tested under this
section shall comprise the entire active
washing mode and exclude any delay start or
cycle finished modes.
To identify the cycle setting with the
highest energy consumption, use the clothes
washer’s maximum test load size, determined
from Table 5.1. For clothes washers with a
manual water fill control system, useradjustable adaptive water fill control system,
or adaptive water fill control system with
alternate manual water fill control system,
use the water fill selector setting resulting in
the maximum water level available for each

3. Test Measurements
3.1 Clothes container capacity. Measure
the entire volume which a dry clothes load
could occupy within the clothes container
during washer operation according to the
following procedures:
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.
3.1.2 Line the inside of the clothes
container with 2 mil (0.051 mm) plastic
sheet. All clothes washer components which
occupy space within the clothes container
and which are recommended for use with the
energy test cycle shall be in place and shall
be lined with 2 mil (0.051 mm) plastic sheet
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 °F ± 5 °F (15.6 °C ± 2.8 °C)
or 100 °F ± 10 °F (37.8 °C ± 5.5 °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.
For a front-loading, horizontal-axis clothes
washer, fill the clothes container to the
uppermost edge that is in contact with the
door seal. For all clothes washers, any
volume which cannot be occupied by the
clothing load during operation must be
excluded from the measurement. Measure
and record the weight of water, W, in
pounds.
3.1.5 The clothes container capacity is
calculated 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/ft3 for 100 °F
(993 kg/m3 for 37.8 °C) or 62.3 lbs/ft3 for
60 °F (998 kg/m3 for 15.6 °C)).
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 of this appendix defines
the sections below which 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.
3.2.1 Inlet water temperature and the
wash/rinse temperature settings.
3.2.1.1 For automatic clothes washers set
the wash/rinse temperature selection control
to obtain the wash water temperature
selection control to obtain the wash water
temperature desired (extra hot, hot, warm, or
cold) and cold rinse, and open both the hot
and cold water faucets.
3.2.1.2 For semi-automatic washers: (1)
For hot 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 water
temperature, close the hot water faucet and
open the cold water faucet completely.
3.2.1.3 Determination of warm wash
water temperature(s) to decide whether a
clothes washer has uniformly distributed
warm wash temperature selections. The wash
water temperature, Tw, of each warm water
wash selection shall be calculated or
measured.
For non-water heating clothes washers,
calculate Tw as follows:
Tw (°F) = ((Hw × 135 °F) + (Cw × 60 °F))/
(Hw + Cw)
or
Tw ( °C) = ((Hw × 57.2 °C) + (Cw × 15.6 °C))/
(Hw + Cw)
where:
Hw = Hot water consumption of a warm
wash.
Cw = Cold water consumption of a warm
wash.
For water-heating clothes washers,
measure and record the temperature of each
warm wash selection after fill.
3.2.2 Total water consumption during the
energy test cycle shall be measured,
including hot and cold water consumption
during wash, deep rinse, and spray rinse.
3.2.3 Clothes washers with adaptive
water fill/manual water fill control systems
3.2.3.1 Clothes washers with adaptive
water fill control system and alternate
manual water fill control systems. If a clothes
washer with an adaptive water fill control
system allows consumer selection of manual
controls as an alternative, then both manual
and adaptive 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 of this appendix. Then the average
of the two values (one from each mode,
adaptive and manual) for each variable shall
be used in section 4 of this appendix for the
clothes washer.
3.2.3.2 Clothes washers with adaptive
water fill control system.
3.2.3.2.1 Not user adjustable. The
maximum, minimum, and average water
levels as defined in the following sections
shall be interpreted to mean that amount of
water fill which is selected by the control
system when the respective test loads are
used, as defined in Table 2.8 of this
appendix. The load usage factors which shall
be used when calculating energy
consumption values are defined in Table
4.1.3 of this appendix.
3.2.3.2.2 User adjustable. Four tests shall
be conducted on clothes washers with user
adjustable adaptive water fill controls which
affect the relative wash water levels. The first
test shall be conducted with the maximum
test load and with the adaptive 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 adaptive 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 adaptive 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 adaptive
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.
3.2.3.3 Clothes washers with manual
water fill control system. In accordance with
Table 2.8 of this appendix, the water fill
selector shall be set to the maximum water
level available on the clothes washer for the
maximum test load size and set to the
minimum water level for the minimum test
load size. The load usage factors which shall
be used when calculating energy
consumption values are defined in Table
4.1.3 of this appendix.

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
which 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
VerDate Mar<15>2010
18:28 Nov 08, 2011
Jkt 226001
the commencement of field tests which may
be used to support a petition for waiver.
Section 6.3 of this appendix provides an
example of 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 energy test 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
consumer laundering conditions or
variations. The clothes washers should be
monitored in such a way as to accurately
record the total energy consumption per
cycle. At a minimum, the following should
PO 00000
Frm 00024
Fmt 4701
Sfmt 4702
be measured and recorded throughout the
test period for each clothes washer: Hot water
usage in gallons (or liters), electrical energy
usage in kilowatt-hours, and the cycles of
usage.
The field test results would be used to
determine the best method to correlate the
rating of the test clothes washer to the rating
of the base clothes washer. If the base clothes
washer is rated at A kWh per year, but field
tests at B kWh per year, and the test clothes
washer field tests at D kWh per year, the test
unit would be rated as follows:
A × (D/B) = G kWh per year
6.3 Adaptive water fill control system
field test. Section 3.2.3.1 of this appendix
defines the test method for measuring energy
consumption for clothes washers which
incorporate control systems having both
adaptive and alternate cycle selections.
Energy consumption calculated by the
method defined in section 3.2.3.1 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 energy test 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
which 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
VerDate Mar<15>2010
18:28 Nov 08, 2011
Jkt 226001
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 loads used in
calculating the in-home percentage split
between adaptive and manual cycle usage
should be only those wash loads which

The statutory authority and background for this SNOPR are the same
as that published in: (1) DOE's notice of proposed rulemaking (NOPR) to
amend the test procedure for residential clothes washers, published in
September 2010 (75 FR 57556, Sept. 21, 2010) (September 2010 NOPR); and
(2) DOE's recent SNOPR to address the incorporation of certain
provisions of IEC 62301 (Second Edition) into the test procedure (76 FR
49238, Aug. 9, 2011) (August 2011 SNOPR). Please see the September 2010
NOPR and August 2011 SNOPR for further details.
II. Summary of the Supplemental Notice of Proposed Rulemaking
The revised clothes washer test procedure amendments DOE is
proposing in today's SNOPR would update the definition of the energy
test cycle. The proposed definition would apply to the revised test
procedure to be published at appendix J2 at 10 CFR 430 subpart B. At
the end of this SNOPR, DOE sets forth the proposed regulatory text from
DOE's proposed test procedure amendments in the September 2010 NOPR, as
amended by the August 2011 SNOPR and today's proposals.
Today's SNOPR covers only the energy test cycle definition. DOE
will discuss all other aspects of the proposed test procedure
revisions, and respond to comments received from interested parties on
those aspects of the proposed revisions, in the final rule.
III. Discussion
A. Today's Proposed Revision for Part (B) of the Energy Test Cycle
Based on the discussion of comments in the following sections, DOE
proposes in today's SNOPR to modify the definition of the energy test
cycle as follows:
Energy test cycle for a basic model means:
(A) The cycle setting recommended by the manufacturer for
washing cotton or linen clothes, and includes all wash/rinse
temperature selections offered in that cycle setting, and
(B) if the cycle setting described in (A) does not include all
wash/rinse temperature combinations available on the clothes
[[Page 69871]]
washer, the energy test cycle shall also include the alternate cycle
setting(s) offering these wash/rinse temperature combination(s),
tested at the wash/rinse temperature combinations not available on
the cycle setting described in (A).
Where multiple alternate cycle settings offer a wash/rinse
temperature combination that is not available on the cycle setting
recommended by the manufacturer for washing cotton or linen clothes,
the cycle setting certified by the manufacturer to have the highest
energy consumption, as measured according to section 2.13, shall be
included in the energy test cycle.
(C) All cycle settings included under part (A) and part (B)
shall be tested using each appropriate load size as defined in
section 2.8 and Table 5.1.
(D) For any cycle setting tested under (A) or (B), the
manufacturer default settings shall be used, except for the
temperature selection, if necessary. This includes wash conditions
such as agitation/tumble operation, soil level, spin speed(s), wash
times, rinse times, and all other wash parameters or optional
features applicable to that cycle, including water heating time for
water heating clothes washers. Each wash cycle included as part of
the energy test cycle shall comprise the entire active washing mode
and exclude any delay start or cycle finished modes.
DOE also proposes to add a new section 2.13 to the revised test
procedure as follows:
2.13 Energy Consumption for the Purpose of Certifying the Cycle
Setting(s) To Be Included in Part (B) of the Energy Test Cycle
Definition
Where multiple alternate cycle settings offer a wash/rinse
temperature combination not available on the cycle setting recommended
by the manufacturer for washing cotton or linen clothes, the cycle
setting with the highest energy consumption, as measured according to
this section, shall be included in the energy test cycle.
To determine which cycle setting has the highest energy
consumption, establish the testing conditions set forth in section 2 of
this test procedure. Select the applicable cycle setting and
temperature combination. Use the manufacturer default settings for
agitation/tumble operation, soil level, spin speed(s), wash times,
rinse times, and all other wash parameters or optional features
applicable to that cycle, including water heating time for water
heating clothes washers. Each wash cycle tested under this section
shall comprise the entire active washing mode and exclude any delay
start or cycle finished modes.
To identify the cycle setting with the highest energy consumption,
use the clothes washer's maximum test load size, determined from Table
5.1. For clothes washers with a manual water fill control system, user-
adjustable adaptive water fill control system, or adaptive water fill
control system with alternate manual water fill control system, use the
water fill selector setting resulting in the maximum water level
available for each cycle setting.
Measure each cycle setting's electrical energy consumption
(EB) and hot water consumption (HB). Calculate
the total energy consumption for each cycle setting (ETB),
as follows:
ETB = EB + (HB x T x K)
Where:
EB is the electrical energy consumption, expressed in
kilowatt-hours per cycle.
HB is the hot water consumption, expressed in gallons per
cycle.
T = temperature rise = 75 [deg]F (41.7 [deg]C)
K = Water specific heat in kilowatt-hours per gallon per degree F =
0.00240 (0.00114 kWh/L-[deg]C)
The provisions proposed in today's rule would be set forth in
appendix J2 and would become effective 30 days after the date of
publication in the Federal Register of the final rule in this test
procedure rulemaking. DOE would clarify in the published amended test
procedures, however, that manufacturers would be required to use
amended appendix J1 until the compliance date of any final rule
establishing amended energy conservation standards that addresses
standby and off mode power consumption for these products. 42 U.S.C.
6295(gg)(2)(C). At such time, manufacturers would begin using the test
procedures in appendix J2. DOE notes that until use of appendix J2 is
required, DOE's guidance on warm rinse and capacity measurement,
available at https://www1.eere.energy.gov/buildings/appliance_standards/residential/clothes_washers.html, is still applicable.
B. Discussion of Energy Test Cycle Definition
The following sections summarize DOE's previous proposals regarding
the energy test cycle definition as well as comments received from
interested parties. Section III.B.1 provides background on the
definition of the energy test cycle. Section III.B.2 summarizes DOE's
proposal published in the September 2010 NOPR and the comments received
from interested parties on the energy test cycle definition. Section
III.B.3 summarizes DOE's proposal published in the August 2011 SNOPR
and the comments received from interested parties on the energy test
cycle definition. Section III.B.4 provides DOE's responses to all
comments received from both the September 2010 NOPR and August 2011
SNOPR that resulted in the proposal stated in section III.A.
1. Background
The ``energy test cycle'' comprises all the wash/rinse temperature
selections currently used in determining the modified energy factor
(MEF) and water factor (WF) for a clothes washer, and proposed to be
used for determining integrated modified energy factor (IMEF) and
integrated water consumption factor (IWF). The energy test cycle is
defined in section 1.7 of the current clothes washer test procedure as
follows:
1.7 Energy test cycle for a basic model means (A) The cycle
recommended by the manufacturer for washing cotton or linen clothes,
and includes 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. Any cycle under
(A) or (B) shall include the agitation/tumble operation, spin
speed(s), wash times, and rinse times applicable to that cycle,
including water heating time for water heating clothes washers.
10 CFR Part 430, Subpart B, Appendix J1
The cycle setting recommended for washing cotton or linen clothes
is commonly referred to as the ``Normal'' setting. DOE has observed
that on clothes washers with electronic control panels, certain wash/
rinse temperature combinations are commonly ``locked out'' of the
Normal setting. In such cases, these wash/rinse temperatures can be
accessed only by switching the control panel selection dial to one of
the other settings (e.g. ``Whites'', ``Heavy Duty'', ``Casual'',
``Permanent Press'', etc.). DOE has observed that the extra-hot wash/
cold rinse and/or warm wash/warm rinse temperature combinations are
locked out of the Normal setting on some clothes washer models that
offer such selections.
In cases where certain wash/rinse combinations are locked out of
the Normal setting, manufacturers may test only the temperature
selections available on the Normal setting, despite being able to
access other wash/rinse temperature selections on other settings.
Testing only the wash temperature selections available in the Normal
setting may neglect part (B) of the energy test cycle definition, which
requires manufacturers to switch out of the Normal setting to a
different setting that allows the other temperature
[[Page 69872]]
combinations to be selected and tested, if such testing ``will
contribute to an accurate representation of energy consumption as used
by consumers.'' Because the temperature selections typically locked out
of the Normal setting are those that use greater quantities of hot
water and thus have higher water heating energy consumption, excluding
them from the energy test cycle could increase a clothes washer's MEF,
while not accurately representing the energy consumption of a
particular machine as used by the consumer.
2. September 2010 NOPR Proposal and Comments Received
In the September 2010 NOPR, DOE noted that the specific language
requiring manufacturers to test different temperature selections if
such testing ``contribute[s] to an accurate representation of energy
consumption as used by consumers'' has caused some confusion and
differences in interpretation among manufacturers and independent test
laboratories. DOE believes the energy test cycle definition must be
clear, uniformly understood, and able to be interpreted consistently by
manufacturers, competitors, and independent test laboratories without
subjective judgment or reliance on proprietary data.
In the September 2010 NOPR, DOE proposed to amend part (B) of the
energy test cycle definition to provide clarity in determining whether
to test temperature selections that are available on the clothes washer
but locked out of the Normal setting. Specifically, DOE proposed
modifying part (B) as follows:
``* * * (B) if the cycle described in (A) Does not include all
wash/rinse temperature settings available on the clothes washer and
required for testing as described in this test procedure, the energy
test cycle shall also include the portions of a cycle setting
offering these wash/rinse temperature settings with agitation/tumble
operation, spin speed(s), wash times, and rinse times that are
largely comparable to those for the cycle recommended by the
manufacturer for washing cotton or linen clothes. Any cycle under
(A) or (B) shall include the default agitation/tumble operation,
soil level, spin speed(s), wash times, and rinse times applicable to
that cycle, including water heating time for water heating clothes
washers.'' 75 FR 57556, 57575-76 (Sept. 21, 2010).
The Association of Home Appliance Manufacturers (AHAM) commented
that DOE's proposal in the September 2010 NOPR to amend part (B) of the
energy test cycle definition was vague, undefined, and included a
significant amount of variability. AHAM noted that variability in a
test procedure has substantial consequences for manufacturers, and that
the test procedure must be clear and be uniformly understood to avoid
significant variations in testing across laboratories or technicians.

written comment made by AHAM; recorded in document number 14 that is
filed in the docket of the clothes washer test procedure rulemaking
(Docket No. EERE-2010-BT-TP-0021); that appears on page 5 of
document number 14.
---------------------------------------------------------------------------
Alliance Laundry Systems (ALS) commented that DOE's proposal is
vague and the proposal would require applying consumer usage factors to
all available settings other than the Normal setting. ALS believes that
different certification test laboratories could not apply part (B) in
any meaningful and consistent manner. Further, ALS believes the burden
on manufacturers and test laboratories to try to utilize part (B) would
be significant and likely unbearable. (ALS, No. 10 at p. 5)
Whirlpool Corporation (Whirlpool) commented that the term ``largely
comparable'' in the proposed part (B) definition is not clear and is
open to the same type of interpretation and confusion that currently
exists, and strongly urged DOE to revise its proposed definition.
(Whirlpool, No. 13 at p. 13)
BSH Home Appliances (BSH) commented that, while it generally agrees
with the proposal to measure a complete warm wash/warm rinse cycle, the
problems suggested by DOE that prompted the proposed revision of part
(B) would return with the proposed wording of the energy test cycle
definition. BSH stated that numerous portions of cycles without defined
start and end points would need to be incorporated into energy data
depending on the interpretation of the words ``largely comparable.''
According to BSH, assembling portions of cycles to test under part (B)
would not represent a cycle setting that a consumer could ever select,
and thus would not be representative of actual consumer usage. (BSH,
No. 20 at p. 4; BSH, Public Meeting Transcript, No. 20 at pp. 188-189)
BSH further stated that it opposes the proposed definition of the
energy test cycle for the following reasons: (1) The proposed
definition would lead to questions about which of the ``largely
comparable'' cycle settings is the ``worst case'' (e.g., the cycle
setting with the highest energy consumption but not the highest water
consumption, the cycle setting with the highest water consumption but
not the highest energy consumption, etcetera); (2) the uncertainty in
interpreting the phrase ``contributes to an accurate representation of
the energy consumption'' would be replaced with similar uncertainty in
interpreting the phrase ``largely comparable.'' Accordingly, BSH
questioned what threshold criteria would be used to determine whether a
setting is close enough to the Normal setting to be considered
comparable. BSH believes that the proposed definition could lead to
every cycle setting having to be measured, with ``largely comparable''
being interpreted differently by manufacturers, certification bodies,
and verification bodies. (BSH, No. 13 at p. 5; BSH, Public Meeting
Transcript. No. 20 at pp. 188, 190, 193)
GE Appliances & Lighting (GE) agreed with AHAM's comments and
offered an alternative definition for the energy test cycle, as
follows:
Energy test cycle for a basic model means (A) The cycle
recommended by the manufacturer for washing cotton or linen clothes,
and includes all wash/rinse temperature selections and water levels
offered in that cycle; and (B) If the cycle described in (A) does
not include all wash/rinse temperature selections available on the
clothes washer, and these selections are required for testing as
described in this test procedure, then the energy test cycle shall
include the other cycles available on the clothes washer tested only
at the wash/rinse temperature selections which are not available on
the cycle described in (A). If a wash/rinse temperature selection
not available in the cycle described in (A) is available on multiple
other cycles provided on the clothes washer, then each cycle with
that wash/rinse temperature selection must be tested and the cycle
resulting in the most energy usage will be included in the energy
test cycle.'' (GE, No. 15 at pp. 1-2)
GE expressed concern that the proposed definition supplied in the
September 2010 NOPR may result in different interpretations of what
should be included in the energy test cycle. Specifically, GE commented
that the interpretation of what would be considered ``largely
comparable to a cottons or linens cycle'' could be variable and affect
the results of an energy test. GE stated that its proposed definition
would clarify the definition and remove as much interpretation as
possible. (GE, No. 15 at pp. 1-2)
Springboard Engineering (Springboard) interpreted the proposed
definition in part (B) as requiring the warm wash/warm rinse
temperature combination to be tested, but questioned whether the
proposed definition provides enough direction such that different test
laboratories would select similar cycle settings on the same clothes
washer. Springboard noted, for example, that some clothes washers
[[Page 69873]]
have three or more warm wash/warm rinse settings to choose among, and
different laboratories might use different criteria to select which
setting to include in the energy test cycle. Springboard stated that it
would choose the cycle setting similar in time and agitation to the
Normal setting; however, Springboard noted that the possibility that
one laboratory could select the ``Colors'' setting, for example, while
another might select the ``Permanent Press'' setting, which could
produce different measured performance. According to Springboard,
different settings may not have the same wash and rinse temperatures or
spin speeds, but such information would not be known without first
testing each setting on the clothes washer and comparing the hot water
usage. Springboard believes that these tests could increase the test
burden. (Springboard, No. 11 at pp. 1-2) Springboard also noted that
the different warm wash/warm rinse settings on a clothes washer may
have different spin speeds, which will affect the remaining moisture
content (RMC) and MEF calculation. Id. Furthermore, Springboard
commented that some laboratories may interpret that a ``Sanitize''
setting with extra-hot wash would not have to be tested because it is
not comparable to the Normal setting. Springboard questioned whether
the intention of part (B) is to test the extra-hot wash temperature
combination, even if it has to be selected with a different setting
such as the ``Sanitize'' setting. (Springboard, No. 11 at p. 2)
The Northwest Energy Efficiency Alliance (NEEA) supports DOE's
proposal to account for temperature options available outside the
``Normal'' setting. NEEA believes DOE clarified this provision in the
proposed language change for part (B) of the energy test cycle. (NEEA,
No. 12 at p. 14)
3. August 2011 SNOPR Proposal and Comments Received
In testing conducted since the September 2010 NOPR, DOE observed
that some clothes washers retain in memory the most recent options
selected for a cycle setting the next time that cycle is run. To ensure
repeatability of test results, particularly for cycles under part (B)
of the energy test cycle definition, DOE proposed in the August 2011
SNOPR to further clarify that the manufacturer default conditions for
each cycle setting shall be used, except for the temperature selection,
if necessary. For example, if the extra-hot temperature selection was
only available on the ``Whites'' setting, the manufacturer would use
the Whites setting to test that temperature option. If the default wash
temperature for the Whites setting was warm or hot, however, the
manufacturer would have to manually adjust the temperature to obtain
the extra-hot wash temperature. For certification testing in this
illustrative case, the manufacturer would use the default settings on
the Whites setting for all options except the temperature selection,
which would be manually adjusted to achieve the desired temperature.
In addition, DOE proposed in the August 2011 SNOPR to delete the
phrase, ``and required for testing as described in this test
procedure'' from part (B) as redundant and unnecessary.
In response to the revised proposal in the August 2011 SNOPR, AHAM
stated that it opposes including the phrase, ``the manufacturer default
settings for each cycle setting shall be used, except for the
temperature selection'' in the energy test cycle definition. AHAM
believes the proposed clarification is vague because it is open to
interpretation by manufacturers. (AHAM, No. 24 at p. 5) AHAM further
stated generally that the proposed clarification to the energy test
cycle definition, as well as the existing part (B) of the definition,
represent significant test burden with no corresponding benefit because
the results are not representative of actual consumer use. (AHAM, No.
24 at p. 5)
ALS opposed the proposed clarification to part (B) of the energy
test cycle definition, stating that the phrase ``largely comparable''
is vague and open to interpretation. (ALS, No. 22 at p. 2) ALS proposed
eliminating part (B) of the energy test cycle definition entirely, due
to the test burden associated with measuring energy use in every
possible cycle option. ALS proposed implementing only part (A) of the
energy test cycle definition, which is ``the cycle recommended by the
manufacturer for washing cotton or linen clothes, and includes all the
wash/rinse temperature selections and water levels offered in that
cycle.'' (ALS, No. 22 at p. 2) ALS supports DOE's proposal to clarify
that the manufacturer's default settings be utilized in the energy test
cycle definition. (ALS, No. 22 at p. 2)
Whirlpool disagreed with part (B) of the energy test cycle
definition as proposed in the August 2011 SNOPR. Whirlpool stated that
part (B) would require including temperature/water level options not
recommended by the manufacturer for washing cotton and linen clothing
because they may lead to clothing damage such as shrinkage, dye
transfer, puckering, or other outcomes unacceptable to the consumer.
(Whirlpool, No. 27 at p. 2) Whirlpool stated that it possesses
proprietary consumer data suggesting that steam and Sanitize cycle
settings are used infrequently, warranting their exclusion from the
energy test cycle definition. (Whirlpool, No. 27 at p. 2) Whirlpool
proposes the following definition for the energy test cycle:
``Energy test cycle for a basic model means the cycle
recommended by the manufacturer for washing cotton or linen clothes,
and includes all wash/rinse temperature selections and water levels
offered in that cycle. If a particular wash/rinse temperature
selection or water level is available on the basic model, but is not
available for selection in the cycle recommended by the manufacturer
for washing cotton or linen clothes (i.e., is locked out of the
cycle), then that temperature selection and/or water level shall not
be included in the energy test cycle.'' (Whirlpool, No. 27 at p. 2).
Whirlpool, ALS, and GE (hereafter referred to as the ``Joint
Manufacturers'') submitted a joint comment on the August 2011 SNOPR.
The Joint Manufacturers agree with AHAM that DOE's proposed amendment
to part (B) in the August 2011 SNOPR is vague because it is open to a
significant amount of interpretation by manufacturers. (Joint
Manufacturers, No. 28 at p. 1) The Joint Manufacturers further agree
with AHAM that the cycle setting recommended for washing cotton or
linen clothes is the cycle setting that is most representative of
consumer use, and if the consumer cannot select a temperature for that
cycle setting, then it is not representative to arbitrarily select
other settings that have that temperature option. The Joint
Manufacturers stated that requiring arbitrary selection of temperatures
adds ambiguity to the test procedure, which results in variability. The
Joint Manufacturers urged DOE to eliminate part (B) from the proposed
definition of the energy test cycle. Id.
The Joint Manufacturers further stated that if DOE nevertheless
decides to retain part (B) of the energy test cycle definition, the
following revised language should be used for part (B):
``* * * (B) if the cycle described in (A) does not include a
water heating option and the clothes washer has a water heating
temperature selection or cycle available, the cycle and temperature
selection recommended by the manufacturer for sanitization,
disinfection or similar must be included in the energy test cycle.
In the case of multiple such cycles, the cycle using the most energy
at the manufacturer default setting must be chosen. If the clothes
washer has a water heating option and the manufacturer does not
recommend a cycle for sanitization, disinfection, or similar, the
energy test cycle shall include the water
[[Page 69874]]
heating cycle and temperature selection with the manufacturer's
default cycle time. Again, in the case of multiple such cycles the
cycle using the most energy at the manufacturer default setting must
be chosen. Any cycle under (A) or (B) shall include the
manufacturer's default agitation/tumble operation, soil level, spin
speeds, wash times, and rinse times applicable to that cycle,
including water heating time for water heating clothes washers.''
(Joint Manufacturers, No. 28 at pp. 1-2; Whirlpool, No. 27 at pp. 2-
3).
NEEA agrees with DOE's proposed changes to the energy test cycle
definition. However, NEEA believes that the point at which the test
cycle starts and ends is not defined in the clothes washer test
procedure. (NEEA, No. 26 at p. 4) NEEA questioned whether the beginning
of the energy test cycle could be defined as the beginning of the
delayed wash cycle, if any; and whether the end of the energy test
cycle could be defined as the beginning of the ``inactive'' mode.
(NEEA, No. 26 at p. 4) NEEA stated that defining the energy test cycle
as starting with the activation of the ``delay start'' mode, if any
(with the duration specified) and ending with the beginning of the
inactive mode (with the duration of the ``cycle finished'' mode, if
any, specified, either in minutes or number of cycles, or both), would
simplify and clarify the test procedure. NEEA believes that while this
could lengthen the energy test cycle itself, a greater amount of
testing time could be saved by not having to set up and measure the
``delay start'' and ``cycle finished'' modes separately. (NEEA, No. 26
at p. 4).
4. DOE Response to All Comments
As outlined in the previous sections, the comments DOE received
from interested parties collectively identify seven concerns related to
its proposed energy test cycle definition:
(1) Vague language. The proposed definition is vague and would lead
to significant variability in interpretation; particularly the phrase
``largely comparable.''
(2) Elimination of part (B). Including part (B) may not provide
benefit to the public interest and should be eliminated entirely.
(3) Representativeness. The cycles required to be tested under the
proposed part (B) are not representative of typical consumer usage
patterns.
(4) Test burden. Third party laboratories could be required to test
numerous alternate cycle settings to determine which cycles are largely
comparable to the normal cycle, which could significantly increase test
burden.
(5) Manufacturer default settings. The energy test cycle definition
should clearly specify whether the manufacturer default settings should
be used, and if so, should clarify which default settings to use.
(6) Suggested alternative definitions. Interested parties suggested
several alternatives for defining the energy test cycle.
(7) Definition of the start and end of each cycle. The energy test
cycle definition should clearly define what constitutes the start and
end of each active wash cycle.
The following sections provide DOE's responses to each of these
issues.
a. Vague Language
Interested parties generally commented that DOE's proposed change
to part (B) of the energy test cycle definition would create just as
much confusion as the current definition. Specifically, interested
parties believe that the proposed definition does not provide clear
enough guidance on how to determine whether a cycle setting is
``largely comparable'' to the Normal setting, which would lead to
significant variability in interpretation and test results.
DOE intended the proposed definition to specify that the
determination of whether to include a cycle setting under part (B) of
the energy test cycle should be made by comparing the agitation/tumble
operation, spin speeds, wash times, and rinse times to those of the
Normal setting. DOE acknowledges, however, that the proposed definition
does not clearly define the boundaries of term ``largely comparable,''
leaving this determination to the subjective judgment of the test
laboratory.
As stated earlier, DOE believes the energy test cycle definition
must be clear, uniformly understood, and able to be interpreted
consistently by manufacturers, competitors, and independent test
laboratories without subjective judgment or reliance on proprietary
data. DOE notes that under the alternative definitions proposed by the
Joint Manufacturers, the determination of which cycle settings to
include under part (B) would be based on an objective numerical
criterion readily determined by any test laboratory: The cycle setting
using the most energy.
DOE recognizes that there are other possible numerical criteria for
determining whether a cycle setting should be included in the energy
test cycle under part (B) of the definition, including the cycle
setting using the least energy, the cycle setting with energy
consumption most similar to that of the Normal setting, or cycle
settings above or below a certain energy consumption threshold.
DOE proposes, however, that including the cycle setting that uses
the most energy would be the most appropriate, objective criterion for
determining which cycle setting should be included under part (B) of
the energy test cycle. This approach would ensure that clothes washers
requiring testing under part (B) of the energy test cycle meet the
applicable energy conservation standard when the maximum energy
consumption representative of average consumer use is tested. This
approach would also provide clarity by requiring only a single variable
to be considered to make the determination. Therefore, DOE proposes in
today's SNOPR that for each wash/rinse temperature combination not
available under the Normal setting, the alternate cycle setting that
uses the most energy must be chosen in the case where multiple
alternate cycle settings offer that wash/rinse temperature combination.
DOE notes that this criterion requires a clear definition of which
components of energy consumption should be included in the measurement
of each cycle setting's energy consumption--e.g. electrical energy, hot
water energy, energy required for moisture removal (i.e., dryer
energy), or a combination of these three energy components. DOE
proposes that the machine electrical energy be included because this is
a direct measure of a form of energy consumption by the clothes washer.
DOE also proposes that the hot water energy be included for the
following reasons: (1) Water temperature is the key characteristic that
determines the need for testing under part (B) of the energy test cycle
definition; (2) water temperature is often one of the primary
parameters that consumers consider when selecting a wash/rinse cycle;
(3) water heating energy represents a significant portion of a cycle's
total energy consumption; (4) the test procedure already requires
measuring hot water consumption for each tested cycle; and (5) a simple
equation can be used to translate hot water quantity into hot water
heating energy.
DOE does not propose to include the drying energy in the
determination of which cycle settings should be tested under part (B)
of the energy test cycle. DOE lacks information on whether an RMC value
that would be measured in alternate cycle settings would be comparable
or analogous to the current RMC metric from which drying energy is
calculated. Currently, RMC is determined for a clothes washer based on
the results of only the cold wash/cold rinse cycle and the warm wash/
[[Page 69875]]
warm rinse cycle (if available), at minimum and maximum spin speeds (if
available), using the maximum load size. Depending on the clothes
washer, this corresponds to between one and four dedicated RMC tests
and could significantly increase the test burden if required to be
performed for each alternate cycle setting. The weighted-average value
obtained from these RMC tests is calculated and considered to be the
average RMC value for the clothes washer, across all cycles. Requiring
the measurement of RMC for the individual cycles comprising the energy
test cycle would be inconsistent with this methodology. Determining the
energy required for moisture removal would require weighing the test
cloth before and after each cycle to determine its remaining moisture
content, which would also impose additional test burden. DOE further
believes that in many circumstances, consumers may not be aware of
variations in spin speed if that information is not displayed on the
front panel of the clothes washer.
For these reasons, DOE does not believe that the drying energy
should be included in determining whether a cycle setting should be
tested under part (B) of the energy test cycle. Therefore, DOE proposes
in today's SNOPR to include the machine electrical energy consumption
and hot water energy consumption when determining each cycle setting's
total energy consumption, in the identification of the cycle setting
that uses the most energy for each wash/rinse temperature combination
to be tested under part (B) of the energy test cycle.
Further, DOE notes that in sections 4.1.3 and 4.1.6 of the current
test procedure, machine electrical energy and hot water energy are
calculated as the weighted averages of each tested load size. Requiring
the testing of multiple load sizes for the purpose of determining which
cycle setting to select for part (B) of the energy test cycle, however,
would unduly increase the test burden. Therefore, DOE proposes in
today's SNOPR to require testing only the clothes washer's maximum load
size, determined from Table 5.1, for the purpose of comparing the
energy consumption of the alternate cycle settings considered under
part (B) of the energy test cycle. Using the maximum load size will
produce the most consistent, repeatable, and conservative results.
In addition, DOE notes inconsistent usage of the word ``cycle'' in
the energy test cycle definition. In some instances, the word ``cycle''
refers to the labeled program setting on the clothes washer (e.g.
``Normal'', ``Whites'', ``Colors'', etc.). In other instances, the word
``cycle'' refers to an individual wash/rinse cycle performed during
active wash mode (e.g. a cold wash/cold rinse cycle). To help reduce
this ambiguity, DOE proposes in today's SNOPR to modify the
nomenclature by using the term ``cycle setting'' to indicate the
labeled program setting on the clothes washer, and the term ``cycle''
to indicate an individual wash/rinse cycle.
b. Elimination of Part (B)
As described in previous sections, manufacturers and AHAM commented
that DOE should eliminate part (B) of the energy test cycle definition,
while NEEA supports keeping part (B) to account for temperature options
available outside the Normal setting.
Wash/rinse temperature combinations locked out of the Normal
setting should also be included in the energy test cycle, and doing so
is representative of average consumer use according to the temperature
use factors (TUFs) in the test procedure. DOE is unaware of any
publicly available data indicating the frequency with which consumers
select the Normal setting versus other cycle settings. However, DOE
notes that the TUFs in the test procedure were developed to represent
consumer selection of different temperature options available on a
clothes washer. Each TUF represents the frequency with which consumers
select a particular temperature option on machines offering that
temperature option. The TUFs do not represent the frequency with which
consumers select a particular temperature option among all clothes
washers on the market. For example, if a particular clothes washer
offers a warm rinse option, the warm rinse TUF indicates that the
typical consumer using that clothes washer will select the warm rinse
option for 27 percent of all wash loads. DOE believes that the energy
test cycle proposed in section III.A, which requires use of part (B) of
the definition if part (A) does not include all wash/rinse temperature
combinations available on the machine, should include any temperature
combination for which a TUF has been developed.
If part (B) of the energy test cycle were to be eliminated, only
the temperature options available in the Normal setting would be
required for testing. Under this scenario, if one clothes washer
offered all available temperature options in the Normal setting, while
a second clothes washer offered the same temperature options but with a
subset of those temperatures locked out of the Normal setting, the
locked out temperature options on the second clothes washer would not
be factored into its energy efficiency rating. This would imply that
consumer behavior would differ for these two clothes washers; i.e.,
that consumers would select the locked out temperature combinations
less frequently on the second machine. DOE is not aware of any data
that quantifies how consumers may adjust their behavior based on the
cycle setting for which a particular temperature option is available
(e.g. ``Normal'', ``Whites'', ``Colors'', etc.) rather than on the
desired temperature option itself.
In addition, if DOE eliminated part (B) from the energy test cycle
definition, manufacturers could arbitrarily exclude temperatures from
the Normal setting, thus excluding them from being tested under the DOE
test procedure. In the most extreme case, a manufacturer could create a
Normal setting that offers only cold water temperatures, and move all
heated water cycles to alternate cycle settings on the machine. In this
case, consumers would likely select the alternate cycle settings for a
significant portion of wash cycles, yet only the cold cycle would be
required for testing under the DOE test procedure.
In summary, DOE believes that if a temperature combination is
``locked out'' of the Normal cycle setting but exists on at least one
alternate cycle setting, it should be included in the energy test cycle
under the assumption that a consumer will switch to one of the
alternate cycles to obtain that wash/rinse temperature combination. For
the reasons stated above, DOE proposes in today's SNOPR to keep part
(B) of the energy test cycle definition, and to require testing of all
temperature combinations available on the machine, including any
temperature options locked out of the Normal setting.
c. Representativeness
Manufacturers and AHAM expressed concern that the wash cycles, or
portions of wash cycles, required to be tested under part (B) are not
representative of consumer usage patterns. As described in the previous
section, DOE does not have data to verify how consumers may adjust
their behavior based on the particular cycle setting for which a
temperature option is available, rather than the desired temperature
option itself.
DOE acknowledges that the wording of part (B) in the current test
procedure and DOE's proposals in the September 2010 NOPR and August
2011 SNOPR include language referring to ``portion(s) of other cycle(s)
with that temperature selection or water level * * *'' that may be
interpreted in different ways. DOE
[[Page 69876]]
does not believe that the energy test cycle should include portions of
individual wash cycles. DOE concurs with BSH that assembling portions
of cycles to test under part (B) (i.e. testing the wash portion of one
cycle in combination with the rinse portion of another cycle) would not
represent a cycle that a consumer could select, and thus would not be
representative of actual consumer usage. As a result, the energy test
cycle should include only complete wash/rinse cycles as programmed on
the clothes washer. Accordingly, DOE proposes in today's SNOPR to
remove the phrase ``portion(s) of other cycles'' from the definition of
energy test cycle.
d. Test Burden
DOE acknowledges that the language it proposed in the September
2010 NOPR and August 2011 SNOPR for part (B) of the energy test cycle
could significantly increase test burden if a laboratory is required to
test numerous alternate cycle settings to determine which cycles are
largely comparable to the normal cycle. Under today's proposal,
manufacturers would test all wash/rinse temperature combinations not
available under part (A) of the energy test cycle definition. Where
multiple cycle settings offer these wash/rinse temperature
combinations, DOE proposes a clear, objective way for manufacturers to
determine of which cycle(s) to include in the energy test cycle. DOE
proposes that for each of these wash/rinse temperature combinations,
manufacturers include the cycle setting that uses the most energy in
the energy test cycle. DOE further proposes to require manufacturers to
certify to DOE the specific cycle settings comprising the energy test
cycle for each basic model of its clothes washer. This list of cycle
settings would be provided to DOE and any test laboratory used by the
manufacturer or DOE, so that neither DOE nor the test laboratory would
be required to independently determine which cycles should be included.
DOE believes that this proposal would eliminate a major source of
ambiguity and inconsistency of test results among various laboratories.
This proposal would require a manufacturer to provide to DOE as
part of its certification the cycle settings that a manufacturer used
to determine each clothes washer's energy efficiency rating. Under
DOE's certification, compliance, and enforcement program in 10 CFR part
429, subpart C, DOE can conduct assessment or enforcement testing to
determine whether the manufacturer's declared energy test cycles are
those cycles for a particular wash/rinse temperature combination that
use the most energy.
e. Manufacturer Default Settings
A typical clothes washer may allow the consumer to adjust certain
parameters of a given cycle setting, such as wash/rinse temperature,
water fill levels, soil level, agitation/tumble operation, spin speed,
wash time, rinse time, and other optional features such as delay start,
cycle-finished activity, steam injection, chemical dispensers, and
signal sounds. For any active wash mode cycle included in the energy
test cycle, the default manufacturer settings should be used for any
parameter not explicitly specified by the test procedure because DOE is
not aware of any data quantifying how often consumers select these
optional features or deviate from the default manufacturer cycle
settings. The test procedure specifies wash/rinse temperatures and
water fill levels for all test cycles, and spin speeds for the RMC test
cycles. DOE proposes in today's SNOPR to clarify in the definition of
the energy test cycle that for any cycle setting tested under part (A)
or (B), the manufacturer default parameters shall be used, except for
the temperature selection, if necessary.
f. Suggested Alternative Definitions
Several manufacturers suggested alternate definitions for the
energy test cycle, including specific suggestions for part (B), as
described previously in sections III.B.2 and III.B.3. In response to
the August 2011 SNOPR, the Joint Manufacturers proposed language for
part (B) that would require testing the extra-hot cycle on water
heating clothes washers. The proposal suggested that in the case of
multiple such cycles, the cycle using the most energy at the
manufacturer default setting must be chosen.
As described in the previous sections, DOE proposes that a cycle
setting's energy consumption be used to determine whether that setting
should be included under part (B). However, the definition proposed by
the Joint Manufacturers would require testing only the extra-hot
temperature setting under part (B). Under this proposal, if other wash/
rinse temperature combinations such as warm wash/warm rinse or hot
wash/cold rinse were also locked out of the Normal setting, they would
not be required for testing. In contrast, GE's proposed definition for
part (B), submitted in response to the September 2010 NOPR, as
discussed previously, would require testing all wash/rinse temperature
selections available on the machine and not included in the Normal
setting.
DOE's proposed definition of energy test cycle would require
testing of all wash/rinse temperature combinations available on the
machine, not just the extra-hot temperature setting, to ensure that the
definition is representative of average consumer use. As stated
previously, DOE's proposed definition of energy test cycle would
include any temperature combination for which a TUF has been developed.
As stated above, if a ``locked out'' temperature combination exists on
at least one alternate cycle setting, a setting with that temperature
combination should be included in the energy test cycle because the
TUFs indicate that a consumer will switch to one of the alternate
settings to obtain that wash/rinse temperature combination.
Therefore, DOE proposes in today's SNOPR to use the criteria
suggested by the Joint Manufacturers for determining which cycle
setting to choose under part (B), and to use language suggested by GE
to require testing all wash/rinse temperature combinations available on
the machine not included in the Normal setting. DOE's revised proposal
for part (B) of the energy test cycle definition is set forth in
section III.A.
g. Definition of the Start and End of Each Cycle
As described previously, NEEA commented that the energy test cycle
does not clearly define the start and end of each wash cycle tested
under the energy test cycle. DOE has observed through its own testing
that delay start and cycle finished features are typically available as
optional features which are not activated by default. Thus, they would
not be activated during the energy test cycle, and the start and finish
of each wash cycle would be unambiguous. DOE acknowledges that as delay
start and cycle finished features become more prevalent in the market,
however, clothes washers could be manufactured that activate some of
these features by default during any of the wash cycles comprising the
energy test cycle. Therefore, DOE proposes to define the start and end
of the energy test cycle more clearly.
In the August 2011 SNOPR, DOE proposed adding definitions for
active washing mode, delay start mode, and cycle finished mode. DOE
believes that these three definitions can be used to clarify the start
and end of the energy test cycle. DOE proposes in today's SNOPR to
specify that each cycle included as part of the energy test cycle
comprises the entire active washing
[[Page 69877]]
mode, and excludes any delay start or cycle finished modes.
C. Compliance With Other EPCA Requirements
1. Test Burden
EPCA requires that any test procedures prescribed or amended under
this section 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. Test procedures must also not be unduly burdensome to
conduct.'' (42 U.S.C. 6293(b)(3))
DOE determined that the proposed test procedure amendments in the
September 2010 NOPR and August 2011 SNOPR satisfy these EPCA
requirements, as described in those rulemaking documents. The proposals
in today's SNOPR also satisfy these requirements, as described in the
following paragraphs.
Commenters stated that the proposed definition of energy test cycle
in the September 2010 NOPR and August 2011 SNOPR would be vague and
could significantly increase the testing burden. Today's proposal is
intended to provide a clear, objective definition of energy test cycle
and would require manufacturers to certify to DOE the list of cycle
settings comprising the energy test cycle for each basic model of its
clothes washers, so that testing laboratories would know which cycles
to test. While the proposed definition of the energy test cycle would
require testing additional wash cycles under part (B) to determine
which cycle setting has the highest energy consumption, the
manufacturer already possesses in-depth knowledge about the energy
characteristics of each wash/rinse cycle offered on its clothes
washers. Other test laboratories would not be required to conduct
multiple tests to determine which cycle settings should be included
under part (B) of the energy test cycle. Therefore, compared to the
current test procedure, DOE expects that today's proposal could reduce
the test burden, because it would remove the existing uncertainty as to
which cycle settings should be selected.
2. Commercial Clothes Washers
The test procedure for commercial clothes washers is required to be
the same test procedure established for residential clothes washers.
(42 U.S.C. 6314(a)(8)) Thus, the test procedure set forth in appendix
J1 of subpart B of 10 CFR part 430 is also currently used to test
commercial clothes washers. (10 CFR part 431.154) The definition of the
energy test cycle proposed in today's SNOPR could affect the
measurement of active mode energy use. DOE notes that 42 U.S.C.
6293(e)(3) provides that models of covered products in use before the
date on which an amended energy conservation standard (developed using
the amended test procedure pursuant to 42 U.S.C. 6293(e)(2)) becomes
effective that comply with the energy conservation standard applicable
to such covered products on the day before such date are deemed to
comply with the amended standard. The same is true of revisions of such
models that come into use after such date and have the same energy
efficiency, energy use or water use characteristics.
IV. Procedural Issues and Regulatory Review
The regulatory reviews conducted for this proposed rule are
identical to those conducted for the August 2011 SNOPR. An update to
the Regulatory Flexibility Act certification is set forth below. Please
see the August 2011 SNOPR for further details.
Review Under the Regulatory Flexibility Act
The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires
preparation of an initial 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://www.gc.doe.gov.
DOE reviewed today's supplemental proposed rule under the
provisions of the Regulatory Flexibility Act and the procedures and
policies published on February 19, 2003. DOE tentatively concluded that
the September 2010 NOPR and August 2011 SNOPR would not have a
significant impact on a substantial number of small entities, and
today's SNOPR contains no revisions to that proposal that would result
in 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 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 North American Industry
Classification System (NAICS). The threshold number for NAICS
classification code 335224, which applies to household laundry
equipment manufacturers and includes clothes washer manufacturers, is
1,000 employees. Searches of the SBA Web site \2\ to identify clothes
washer manufacturers within these NAICS codes identified, out of
approximately 17 manufacturers supplying clothes washers in the United
States, only one small business. This small business manufactures
laundry appliances, including clothes washers. The other manufacturers
supplying clothes washers are large, multinational corporations.
---------------------------------------------------------------------------
\2\ A searchable database of certified small businesses is
available online at: https://dsbs.sba.gov/dsbs/search/dsp_dsbs.cfm.
---------------------------------------------------------------------------
The proposed rule would amend DOE's test procedure by revising the
definition of energy test cycle to more precisely define which cycles
are required for testing under part (B) of the definition.
DOE believes these additional requirements would not be expected to
impose a significant economic burden on entities subject to the
applicable testing requirements. Today's proposal is intended to
provide a clear, objective definition of energy test cycle, which is
expected to reduce the testing burden. The provisions in today's SNOPR
would also require manufacturers to report to DOE the cycle settings
comprising the complete energy test cycle for each basic model.
Manufacturers already possess in-depth knowledge about the energy
characteristics of each wash/rinse cycle offered on their clothes
washers, so DOE expects manufacturers to experience little or no
additional test burden due to today's proposed revisions.
For these reasons, DOE certifies that if adopted, the September
2010 NOPR, as modified by the August 2011 SNOPR and today's SNOPR,
would not have a significant economic impact on a substantial number of
small entities. Accordingly, DOE has not prepared a regulatory
flexibility analysis for this rulemaking. DOE has previously
transmitted the 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).
