Energy Conservation Program: Test Procedures for Residential 
Dishwashers and Cooking Products

AGENCY: Office of Energy Efficiency and Renewable Energy, Department of 
Energy.

ACTION: Supplemental notice of proposed rulemaking.

-----------------------------------------------------------------------

SUMMARY: The U.S. Department of Energy (DOE) proposes to amend its test 
procedures for residential dishwashers to update certain obsolete 
dishware, flatware and food items, make minor amendments to the 
definition of the normal cycle, and update the ambient temperature and 
preconditioning requirements as well as the industry test method 
referenced in DOE's test procedure. DOE also proposes to add water 
pressure, drain height, rack position, loading, rinse aid container, 
and soil preparation specifications to the dishwasher test procedure. 
DOE additionally proposes to amend the test procedures for both 
dishwashers and conventional cooking products for the measurement of 
energy use in fan-only mode.

I. Authority and Background

    Title III, Part B \1\ of the Energy Policy and Conservation Act of 
1975 (EPCA or the Act), Public Law 94-163 (42 U.S.C. 6291-6309, as 
codified) sets forth a variety of provisions designed to improve energy 
efficiency and established the Energy Conservation Program for Consumer 
Products Other Than Automobiles, a program covering most major 
household appliances.\2\ These include residential dishwashers and 
conventional cooking products,\3\ the subject of today's notice. (42 
U.S.C. 6292(a)(6) and (10); 6295(cc))
---------------------------------------------------------------------------

    \1\ For editorial reasons, upon codification in the U.S. Code, 
Part B was redesignated Part A.
    \2\ All references to EPCA in this rulemaking refer to the 
statute as amended through the Energy Independence and Security Act 
of 2007, Public Law 110-140.
    \3\ The term ``conventional cooking products,'' as used in this 
notice, refers to residential electric and gas kitchen ovens, 
ranges, and cooktops (other than microwave ovens).
---------------------------------------------------------------------------

    Under the Act, this program consists essentially of four parts: (1) 
Testing, (2) labeling, (3) establishing Federal energy conservation 
standards, and (4) certification and enforcement procedures. The 
testing requirements consist of test procedures that manufacturers of 
covered products must use: (1) As the basis for certifying to DOE that 
their products comply with applicable energy conservation standards 
adopted pursuant to EPCA, and (2) for making representations about the 
efficiency of those products. (42 U.S.C. 6293(c); 6295(s)) Similarly, 
DOE must use these test procedures in any enforcement action to 
determine whether the products comply with these energy conservation 
standards. (42 U.S.C. 6295(s))

[[Page 49065]]

General Test Procedure Rulemaking Process

    Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures 
DOE must follow when prescribing or amending test procedures for 
covered products. EPCA provides in relevant part that test procedures 
be reasonably designed to produce test results which measure energy 
efficiency, energy use, or estimated annual operating cost of a covered 
product during a representative average use cycle or period of use, as 
determined by the Secretary of Energy, and not unduly burdensome to 
conduct. (42 U.S.C. 6293(b)(3)) In addition, if DOE determines that a 
test procedure amendment is warranted, it must publish proposed test 
procedures and offer the public an opportunity to present oral and 
written comments on them. (42 U.S.C. 6293(b)(2))
    DOE's test procedure for dishwashers is found in the Code of 
Federal Regulations (CFR) at 10 CFR part 430, subpart B, appendix C. 
DOE's test procedures for conventional ranges, cooktops, and ovens 
(including microwave ovens, which are considered separately from the 
conventional cooking products covered in today's rule) are found at 10 
CFR part 430, subpart B, appendix I. For background on the 
establishment of the first DOE test procedures for dishwashers and 
conventional cooking products, subsequent amendments to those 
procedures, and the rulemaking history for today's supplemental notice 
of proposed rulemaking (SNOPR), please see the SNOPR issued on May 25, 
2012. (77 FR 31444) (May 2012 SNOPR). In today's SNOPR, DOE considers 
comments received on the dishwasher test procedure in response to the 
May 2012 SNOPR and during a public meeting held June 1, 2012 (June 2012 
Public Meeting). DOE will provide further response to comments received 
on the May 2012 SNOPR, as appropriate, in any final rule to establish 
amended test procedures.

II. Discussion

A. Proposals

Obsolete Dishware and Food Items
    In the May 2012 SNOPR, DOE proposed to update obsolete flatware and 
detergent specifications. DOE has determined that certain additional 
flatware, dishware, and food items used in the test procedure are also 
obsolete, or has received comments in this test procedure rulemaking 
indicating that the items may be obsolete. These items include: The cup 
and saucer, the bread and butter plate, the fruit bowl, the dinner 
fork, the salad fork, the teaspoon, the knife, the margarine, and the 
coffee. In today's SNOPR, DOE proposes to use the items listed in Table 
I in place of the obsolete or potentially obsolete items. DOE further 
proposes that use of these items be required 30 days after publication 
of any final amended test procedures and seeks comment on whether the 
specified items can be procured in 30 days.

------------------------------------------------------------------------

Definition of Normal Cycle
    In the May 2012 SNOPR, DOE stated that the current DOE dishwasher 
test procedure defines the normal cycle as ``the cycle type recommended 
by the manufacturer for completely washing a full load of normally 
soiled dishes including the power-dry feature.'' (Section 1.6 of 10 CFR 
part 430, subpart B, appendix C) DOE noted that it is aware that 
certain dishwashers have multiple wash and/or drying temperature 
options for the cycle setting required under the normal cycle 
definition. For these dishwashers, DOE proposed to clarify in the 
definition that the normal cycle shall include the wash and drying 
temperature options recommended by the manufacturer for completely 
washing a full load of normally soiled dishes including the power-dry 
feature. DOE sought comment on the wash and drying temperature options 
to be selected in the case that the cycle setting required under the 
normal cycle definition has multiple wash and/or drying temperature 
options but the manufacturer does not provide such a recommendation.
    In response to the May 2012 SNOPR, commenters suggested that in the 
absence of a manufacturer recommendation concerning temperature options 
for the normal cycle, the highest energy consumption temperature 
options should be selected. This approach is consistent with the 
approach taken in DOE's recent rulemaking to amend the test procedure 
for residential clothes washers (77 FR 13888, Mar. 7, 2012). In that 
rulemaking, DOE amended part (B) of the definition of energy test cycle 
to state that where multiple alternative selections offer a wash/rinse 
temperature selection for which a temperature use factor has been 
developed and that is not available on the cycle recommended by the 
manufacturer for washing cotton or linen clothes described in part (A) 
of the energy test cycle definition, the alternate cycle selection with 
the highest energy consumption for that TUF must be included in the 
energy test cycle. For consistency with the approach taken in the 
clothes washer test procedure rulemaking, and to ensure that the test 
procedure does not

[[Page 49066]]

under-estimate the energy use of the dishwasher, DOE proposes in 
today's SNOPR that in the definition of normal cycle, in the absence of 
a manufacturer recommendation on temperature options, the highest 
energy consumption temperature options for washing and drying must be 
selected.
Ambient Temperature
    DOE proposed in the May 2012 SNOPR to maintain the current room 
ambient air temperature requirement of 75 degrees Fahrenheit ([deg]F) 
5 [deg]F, while allowing greater tolerance on the room air 
temperature during standby mode and off mode testing in accordance with 
provisions incorporated by reference from the International 
Electrotechnical Commission (IEC) Standard 62301, ``Household 
electrical appliances--Measurement of standby power'', Edition 2.0 
2011-01 (IEC Standard 62301). DOE received comments that the more 
stringent active mode ambient temperature conditions should apply to 
all testing, including standby mode and active mode testing performed 
separately from active mode testing to ensure accurate, repeatable, and 
reproducible results. Commenters also stated that the test procedure 
should clarify that the tolerances specified indicate the allowable 
limits of variation in temperature, but do not permit the deliberate 
variation with those limits. Commenters also suggested that DOE tighten 
the tolerance on the ambient temperature to  2 [deg]F, 
because a 1 [deg]F ambient temperature change can result in a 1.5 
kilowatt-hour (kWh) change in estimated annual energy use (EAEU), 
although the commenters acknowledged that this tighter tolerance could 
be burdensome for certain manufacturers or laboratories.
    In specifying tolerances in its test procedures, DOE provides a 
range of temperatures under which the test results are considered 
valid, regardless of the reasons for why a particular temperature 
within the range was selected or achieved. Therefore, DOE is not 
proposing to state that the test should be conducted at the nominal 
center of the ambient temperature range. DOE recognizes the impact of 
ambient temperature on the active mode measurement, however, and as an 
alternative to the 5 [deg]F tolerance previously proposed, 
DOE proposes to tighten the tolerance to 2 [deg]F. DOE 
seeks comment on the capabilities of test laboratories to maintain this 
tolerance and the burden associated with it. DOE is not proposing in 
today's SNOPR to require that standby mode and off mode testing be 
conducted under the same ambient temperature as active mode testing 
because no data are available to suggest that the standby mode and off 
mode power of residential dishwashers varies significantly within the 
allowable ambient temperature range of IEC Standard 62301, and because 
this approach would increase the burden for those manufacturers or 
laboratories that choose to conduct standby mode and off mode testing 
separately from active mode testing.
Preconditioning
    DOE proposed in the May 2012 SNOPR to require that the 
preconditioning cycle for soil-sensing dishwashers be run using the 
cycle setting selected for active mode, and that the power supply to 
the unit be continuously maintained throughout testing, including after 
the preconditioning cycle and in between all energy test cycles, to 
maintain calibration of the turbidity sensor. Comments received from 
manufacturers indicated that certain dishwashers may be designed to 
self-calibrate in one cycle, but may sometimes require an additional 
cycle to perform this calibration. In addition, commenters noted that 
two preconditioning cycles would help to clean out residual dirt from 
the machine prior to sensor calibration and energy testing. DOE agrees 
that two preconditioning cycles would ensure a clean unit at the start 
of testing and proper sensor calibration in soil-sensing dishwashers 
that may, under certain conditions, not self-calibrate in one cycle. 
Therefore, in today's SNOPR, DOE proposes two preconditioning cycles, 
clarifying that the second preconditioning cycle is to be used to 
determine detergent dosing. DOE seeks comment on the burden associated 
with requiring an additional preconditioning cycle.
Updated Industry Test Method
    In the May 2012 SNOPR, DOE referenced AHAM's current dishwasher 
test method, DW-1-2009, in the discussion of its proposal to update 
obsolete flatware, but did not propose to incorporate that updated test 
method. In today's SNOPR, DOE proposes to incorporate by reference the 
updated industry test standard AHAM DW-1-2009, which upon acceptance by 
ANSI is designated as ANSI/AHAM DW-1-2010, American National Standard, 
``Household Electric Dishwashers.'' DOE seeks comment on whether the 
incorporation of this standard will affect the measured energy use of 
dishwashers tested according to DOE's test procedure, and if so the 
magnitude of that effect. DOE will determine, as a result of these 
comments, whether to retain the current industry standard or update the 
standard to ANSI/AHAM DW-1-2010.
Water Pressure
    In the May 2012 SNOPR, DOE proposed that the water supply pressure 
during testing be maintained at 35 2.5 pounds per square in 
gauge (psig) when the water is flowing. DOE received comments that, for 
repeatability and reproducibility, the duration of the transient 
pressure drop when the water supply valve first opens should be 
minimized. Commenters suggested allowing a maximum time of 2 seconds to 
ensure that the water is flowing into the dishwasher at the proper 
pressure during the test. DOE agrees that transient pressure variations 
should be minimized for reasons of test stability and reproducibility, 
and, based on commenters indication of laboratory capabilities, 
proposes to require that proper pressure be achieved within 2 seconds. 
DOE seeks comment on this requirement, in particular whether this 
requirement can be reasonably achieved in all laboratories.
Drain Height
    Drain height is not currently specified in the dishwasher test 
procedure, and DOE received comments that such a specification should 
be added to reduce testing variability. The commenters recommended that 
the drain height should be specified according to the manufacturer's 
installation instructions. In the absence of such instructions, a drain 
height of 20 inches would be specified, which according to the 
commenters is a standard height. DOE agrees that the use of 
manufacturer's instructions for drain height, or a standard height in 
the absence of such information, would improve reproducibility of the 
test and is proposing in today's SNOPR corresponding amendments to the 
dishwasher test procedure, including a standard drain height of 20 
inches. DOE seeks comment and information on the standard drain height, 
and may adjust the value accordingly.
Rack Position and Loading
    Commenters on the May 2012 SNOPR noted that the dishwasher test 
procedure does not specify an upper rack position or where the soiled 
dishes are placed on the racks, and recommended adjusting the rack 
position and loading the soiled dishware according to the 
manufacturer's recommendation. DOE concludes that such clarifications 
would improve test repeatability and reproducibility, and proposes such

[[Page 49067]]

amendments to the dishwasher test procedure in today's SNOPR. DOE seeks 
comment on this proposal.
Rinse Aid Container
    The dishwasher test procedure precludes the use of rinse aid during 
testing, including preconditioning. DOE was notified by commenters that 
some laboratories may be filling the rinse aid container in certain 
dishwashers with water during testing to prevent the energy consumption 
of an indicator light that is energized when the rinse aid level is 
low. However, as one commenter noted, the thermal mass of the water in 
the rinse aid container would necessitate additional water heating 
energy during the test. For consistency in testing, therefore, DOE 
clarifies in today's SNOPR that the rinse aid container should not be 
filled with water for energy testing. DOE welcomes comment on this 
proposal.
Soil Preparation
    DOE received comments on the May 2012 SNOPR stating that DOE should 
clarify in the dishwasher test procedure the length of time that soils 
may sit before they are applied to the dishware to prevent stiffening 
and settling. DOE therefore proposes in today's SNOPR that the test 
procedure require the potatoes be used within 30 minutes of preparation 
and the reconstituted milk be allowed to be stored for use over the 
course of 1 day, as recommended by commenters. DOE's proposal includes 
provisions for reconstituting the milk. DOE also proposes to adopt the 
commenters' recommendation that the 1-pound packages of ground beef 
shall be stored frozen for no more than 6 months.
Fan-Only Mode Energy Use
    In the May 2012 SNOPR, DOE proposed a test method to measure the 
energy use of dishwashers and cooking products in fan-only mode. DOE 
received comments on the May 2012 SNOPR stating that fan-only mode 
energy use should be measured only if it is not a user-selectable item. 
Commenters also indicated that DOE's proposal for measuring the energy 
use of fan-only mode at the end of each test cycle would create a 
considerable test burden. In response to these comments, DOE continues 
to consider the approach set forth in the May 2012 SNOPR but is also 
considering an alternative approach. Under this approach, the energy 
use of fan-only mode would be measured only if it is not a user-
selectable item. DOE understands that this change will not 
significantly alter the May 2012 proposal because fan-only mode is 
almost always not a user-selectable item. For cooking products, fan-
only mode runs automatically for safety reasons, and for dishwashers, 
DOE understands that fan-only mode energy use is not typically selected 
independently but would be a function of the drying option selected as 
part of the test cycle. Also under the alternative approach, the energy 
use of fan-only mode would be measured for a brief time period, such as 
10 minutes, and then extrapolated over the length of the entire fan-
only mode cycle, which DOE research suggested may range from 10 minutes 
to several hours for both dishwashers and conventional ovens. To adopt 
this alternative approach, however, DOE would need additional, 
representative data on the length of these cycle times, so that the 
extrapolation provides an accurate measurement of the energy use during 
the fan-only mode cycle. DOE therefore seeks representative data on the 
length of the fan-only mode cycle for dishwashers and conventional 
cooking products. In the absence of such data, DOE may adopt the 
proposal set forth in the May 2012 SNOPR.
Technical Correction
    In the May 2012 SNOPR, DOE inadvertently proposed in section 4.4.2 
of the dishwasher test procedure language that refers to section 1.11 
of the test procedure. DOE corrects that proposal in today's SNOPR to 
properly refer to section 1.13.
    Other than the specific amendments newly proposed in today's SNOPR, 
DOE continues to propose the test procedure amendments originally 
included in the December 2010 NOPR and the September 2011 SNOPR. For 
the reader's convenience, DOE has reproduced in this SNOPR the entire 
body of proposed regulatory text from the December 2010 NOPR and 
September 2011 and May 2012 SNOPRs, further amended as appropriate 
according to today's proposals. DOE's supporting analysis and 
discussion for the portions of the proposed regulatory text not 
affected by this SNOPR may be found in the December 2010 NOPR (75 FR 
75290 (Dec. 2, 2010)), the September 2011 SNOPR (76 FR 58346 (Sept. 20, 
2011)), and the May 2012 SNOPR (77 FR 31444 (May 25, 2012)).

B. Compliance With Other EPCA Requirements

    EPCA requires test procedures to be reasonably designed to produce 
test results which measure energy efficiency, energy use, or estimated 
annual operating cost of a covered product during a representative 
average use cycle or period of use, and not unduly burdensome to 
conduct. (42 U.S.C. 6293(b)(3))
    For the reasons stated in the December 2010 NOPR and September 2011 
and May 2012 SNOPRs, DOE tentatively concluded that the amended test 
procedures would produce test results that measure the standby mode and 
off mode power consumption during representative use, and that the test 
procedures would not be unduly burdensome to conduct. DOE continues to 
make these assertions for today's SNOPR because the substituted items 
replace items that DOE determined to obsolete, or has received comments 
in this test procedure rulemaking process that the items are obsolete. 
The replacement items are intended to be inexpensive, representative of 
commonly-found items, and in some cases already used by manufacturers 
in testing dishwashers. In addition, DOE is proposing a definition of 
normal cycle for dishwashers supported by manufacturers because it will 
lead to consistent, representative results. The updated industry test 
method for dishwashers was also supported by manufactures because it 
will lead to, among other things, reduced test variation, as would the 
proposals for consistent preparation time for the soils used in the 
test procedure, the positioning of the dishwasher rack during testing, 
the method of loading, the tighter tolerances on ambient temperature, 
the added specifications for water pressure measurement and drain 
height, and the clarifications for the rinse aid container. Finally, 
DOE is proposing an alternative method of measuring the energy use in 
fan-only mode for dishwashers and cooking products that could 
significantly decrease overall testing time.

III. Procedural Issues and Regulatory Review

    DOE has concluded that the determinations made pursuant to the 
various procedural requirements applicable to the December 2010 NOPR 
and September 2011 and May 2012 SNOPRs remain unchanged for this SNOPR. 
These determinations are set forth in the December 2010 NOPR (75 FR 
75290, 75317-19 (Dec. 2, 2010)), the September 2011 SNOPR (76 FR 58346, 
58355 (Sept. 20, 2011)), and the May 2012 SNOPR (77 FR 31444, May 25, 
2012). An update to the Regulatory Flexibility Act certification is set 
forth below.
    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires 
preparation of a regulatory flexibility analysis for any rule that by 
law must be proposed

[[Page 49068]]

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: 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 December 2010 NOPR and September 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 
updates to the factual basis for this certification are 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 335228, titled ``Other Major Household Appliance 
Manufacturing,'' is 500 employees; this classification specifically 
includes residential dishwasher manufacturers. Additionally, the 
threshold number for NAICS classification code 335221, titled 
``Household Cooking Appliance Manufacturing,'' is 750 employees; this 
classification specifically includes manufacturers of residential 
conventional cooking products. The threshold number for NAICS 
classification code 335211, titled ``Electric Housewares and Household 
Fan Manufacturing,'' is 750 employees; this classification specifically 
includes manufacturers of dehumidifiers.
    DOE surveyed the AHAM member directory to identify manufacturers of 
residential dishwashers and conventional cooking products. DOE then 
consulted publicly-available data, purchased company reports from 
vendors such as Dun and Bradstreet, and contacted manufacturers, where 
needed, to determine if they meet the SBA's definition of a ``small 
business manufacturing facility'' and have their manufacturing 
facilities located within the United States. Based on this analysis, 
DOE estimates that there are no small businesses that manufacture 
dishwashers and two small businesses that manufacture conventional 
cooking products. Only one provision of today's supplemental proposal 
would affect manufacturers of conventional cooking products, the 
alternative proposal to measure the energy use in fan-only mode. Under 
today's supplemental proposal, that energy use would not be measured at 
the end of each test cycle. Rather, the energy use in fan-only mode 
would be measured for a brief period, such as 10 minutes, and then 
extrapolated over the duration of the entire cycle. This proposal could 
significantly decrease the test burden for manufacturers of 
conventional cooking products.
    For these reasons, DOE continues to certify that the proposed rule 
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 will transmit 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). DOE 
seeks comment on the updates to the certification that are set forth 
above.

Perform a test cycle by establishing the testing conditions set 
forth in section 2 of this Appendix, setting the dishwasher to the 
cycle type to be tested according to section 2.6.1.1, 2.6.2.1, or 
2.6.3.1 of this Appendix, initiating the cycle, and allowing the 
cycle to proceed to completion.
    4.1.1 Measure the water consumption, VWS,i, expressed 
as the number of gallons of water delivered to the machine during 
the entire test cycle, using a water meter as specified in section 
3.3 of this Appendix, where i is the number of times the cycle has 
been conducted. Measure the machine electrical energy consumption, 
MWS,i, expressed as the number of kilowatt-hours of 
electricity consumed by the machine during the entire test cycle, 
using a watt-hour meter as specified in section 3.5 of this 
Appendix.
    4.1.2 Repeat the cycle as specified in section 4.1.1 of this 
Appendix. If:
[GRAPHIC] [TIFF OMITTED] TP15AU12.000

    Then VWSmax is defined as the larger of 
VWS,1 and VWS,2, and VWSavg is 
defined as the smaller of VWS,1 and VWS,2; and 
MWSmax is defined as the machine electrical energy 
consumption for the cycle associated with VWSmax, and

[GRAPHIC] [TIFF OMITTED] TP15AU12.003

    Otherwise, if a maximum total of 10 cycles have been conducted 
and no cycle is determined to have water consumption that is 10 
percent higher than the average water consumption of the other 
cycles, then the unit shall be deemed not a water-softening 
dishwasher.
    4.2 Active mode cycle. Perform a test cycle by establishing the 
testing conditions set forth in section 2 of this Appendix, setting 
the dishwasher to the cycle type to be tested according to section 
2.6.1.2, 2.6.2.2, or 2.6.3.2 of this Appendix, initiating the cycle, 
and allowing the cycle to proceed to completion.

electrical energy consumption, M, expressed as the number of 
kilowatt-hours of electricity consumed by the machine during the 
entire test cycle, using a water supply temperature as set forth in 
section 2.3 of this Appendix and using a watt-hour meter as 
specified in section 3.5 of this Appendix.
    4.2.2 Fan electrical energy consumption. If the dishwasher is 
capable of operation in fan-only mode, measure the fan electrical 
energy consumption, MF, expressed as the number of 
kilowatt-hours of electricity consumed by the machine in fan-only 
mode, by measuring the watt-hours consumed for a period of 10 
minutes in fan-only mode, using a watt-hour meter as specified in 
section 3.5 of this Appendix. Multiply that value by [the number of 
minutes spent in fan-only mode, LF] and divide by 10,000.
    4.2.3 Water consumption. Measure the water consumption, V, 
expressed as the number of gallons of water delivered to the machine 
during the entire test cycle, using a water meter specified in 
section 3.3 of this Appendix.
    4.3 Simplified standby mode power. Connect the dishwasher to a 
standby wattmeter or a standby watt-hour meter as specified in 
sections 3.6 and 3.7, respectively, of this Appendix. Select the 
conditions necessary to achieve operation in the simplified standby 
mode as defined in section 1.19 of this Appendix. Monitor the power 
consumption but allow the dishwasher to stabilize for at least 5 
minutes. Then monitor the power consumption for at least an 
additional 5 minutes. If the power level does not change by more 
than 5 percent from the maximum observed value during the later 5 
minutes and if there is no cyclic or pulsing behavior of the load, 
the load can be considered stable. For stable operation, simplified 
standby mode power, Sm, can be recorded directly from the 
standby watt meter in watts or accumulated using the standby watt-
hour meter over a period of at least 5 minutes. For unstable 
operation, the energy must be accumulated using the standby watt-
hour meter over a period of at least 5 minutes and must capture the 
energy use over one or more complete cycles. Calculate the average 
simplified standby mode power, Sm, expressed in watts by 
dividing the accumulated energy consumption by the duration of the 
measurement period.
    4.4 Standby mode and off mode power. Connect the dishwasher to a 
standby mode and off mode watt meter as specified in section 3.8 of 
this Appendix. Establish the testing conditions set forth in 
sections 2.1, 2.2, and 2.5.2 of this Appendix. For dishwashers that 
take some time to enter a stable state from a higher power state as 
discussed in Section 5, Paragraph 5.1, note 1 of IEC 62301 
(incorporated by reference; see Sec.  430.3), allow sufficient time 
for the dishwasher to reach the lower power state before proceeding 
with the test measurement. Follow the test procedure specified in 
Section 5, Paragraph 5.3.2 of IEC 62301 for testing in each possible 
mode as described in sections 4.4.1 and 4.4.2 of this Appendix.
    4.4.1 If the dishwasher has an inactive mode, as defined in 
section 1.10 of this Appendix, measure and record the average 
inactive mode power of the dishwasher, PIA, in watts.
    4.4.2 If the dishwasher has an off mode, as defined in section 
1.13 of this Appendix, measure and record the average off mode 
power, POM, in watts.

Appendix I to Subpart B of Part 430--Uniform Test Method for Measuring 
the Energy Consumption of Conventional Ranges, Conventional Cooking 
Tops, Conventional Ovens, and Microwave Ovens

    Note:  The procedures and calculations in this Appendix I need 
not be performed to determine compliance with energy conservation 
standards for conventional ranges, conventional cooking tops, 
conventional ovens, and microwave ovens at this time. However, any 
representation related to standby mode and off mode energy 
consumption of conventional ranges, conventional cooking tops, and 
conventional ovens made after (date 180 days after date of 
publication of the test procedure final rule in the Federal 
Register) and of microwave ovens made after September 6, 2011 must 
be based upon results generated under this test procedure, 
consistent with the requirements of 42 U.S.C. 6293(c)(2). Upon the 
compliance date of any energy conservation standard that 
incorporates standby mode and off mode energy consumption, 
compliance with the applicable provisions of this test procedure 
will also be required. Future revisions may add relevant provisions 
for measuring active mode in microwave ovens.

1. Definitions

    1.1 Active mode means a mode in which the product is connected 
to a mains power source, has been activated, and is performing the 
main functions of producing heat by means of a gas flame, electric 
resistance heating, or microwave energy, or circulating air 
internally or externally to the cooking product. Delay start mode is 
a one-off, user-initiated, short-duration function that is 
associated with an active mode.
    1.2 Built-in means the product is supported by surrounding 
cabinetry, walls, or other similar structures.
    1.3 Combined low-power mode means the aggregate of available 
modes other than active mode.
    1.4 Cycle finished mode means a standby mode in which a 
conventional cooking top, conventional oven, or conventional range 
provides continuous status display following operation in active 
mode.
    1.5 Drop-in means the product is supported by horizontal surface 
cabinetry.
    1.6 Fan-only mode means an active mode that is not user-
selectable and in which a fan circulates air internally or 
externally to the cooking product for a finite period of time after 
the end of the heating function, as indicated to the consumer.
    1.7 Forced convection means a mode of conventional oven 
operation in which a fan is used to circulate the heated air within 
the oven compartment during cooking.
    1.8 Freestanding means the product is not supported by 
surrounding cabinetry, walls, or other similar structures.
    1.9 IEC 62301 First Edition means the test standard published by 
the International Electrotechnical Commission, titled

[[Page 49079]]

``Household electrical appliances--Measurement of standby power,'' 
Publication 62301 (First Edition 2005-06) (incorporated by 
reference; see Sec.  430.3).
    1.10 IEC 62301 Second Edition means the test standard published 
by the International Electrotechnical Commission, titled ``Household 
electrical appliances--Measurement of standby power,'' Publication 
62301 (Edition 2.0 2011-01) (incorporated by reference; see Sec.  
430.3).
    1.11 Inactive mode means a standby mode that facilitates the 
activation of active mode by remote switch (including remote 
control), internal sensor, or timer, or that provides continuous 
status display.
    1.12 Normal nonoperating temperature means the temperature of 
all areas of an appliance to be tested are within 5 [deg]F (2.8 
[deg]C) of the temperature that the identical areas of the same 
basic model of the appliance would attain if it remained in the test 
room for 24 hours while not operating with all oven doors closed.
    1.13 Off mode means a mode in which the product is connected to 
a mains power source and is not providing any active mode or standby 
mode function, and where the mode may persist for an indefinite 
time. An indicator that only shows the user that the product is in 
the off position is included within the classification of an off 
mode.
    1.14 Primary energy consumption means either the electrical 
energy consumption of a conventional electric oven or the gas energy 
consumption of a conventional gas oven.
    1.15 Secondary energy consumption means any electrical energy 
consumption of a conventional gas oven.
    1.16 Standard cubic foot (L) of gas means that quantity of gas 
that occupies 1 cubic foot (L) when saturated with water vapor at a 
temperature of 60[emsp14][deg]F (15.6 [deg]C) and a pressure of 30 
inches of mercury (101.6 kPa) (density of mercury equals 13.595 
grams per cubic centimeter).
    1.17 Standby mode means any modes where the product is connected 
to a mains power source and offers one or more of the following 
user-oriented or protective functions which may persist for an 
indefinite time: (a) To facilitate the activation of other modes 
(including activation or deactivation of active mode) by remote 
switch (including remote control), internal sensor, or timer; (b) 
continuous functions, including information or status displays 
(including clocks) or sensor-based functions. A timer is a 
continuous clock function (which may or may not be associated with a 
display) that provides regular scheduled tasks (e.g., switching) and 
that operates on a continuous basis.
    1.18 Thermocouple means a device consisting of two dissimilar 
metals which are joined together and, with their associated wires, 
are used to measure temperature by means of electromotive force.

3. Test Methods and Measurements

* * * * *
    3.1.1 Conventional oven. Perform a test by establishing the 
testing conditions set forth in section 2, Test Conditions, of this 
Appendix and turn off the gas flow to the conventional cooking top, 
if so equipped. Before beginning the test, the conventional oven 
shall be at its normal nonoperating temperature as defined in 
section 1.12 and described in section 2.6 of this Appendix. Set the 
conventional oven test block W1 approximately in the 
center of the usable baking space. If there is a selector switch for 
selecting the mode of operation of the oven, set it for normal 
baking. If an oven permits baking by either forced convection by 
using a fan, or without forced convection, the oven is to be tested 
in each of those two modes. The oven shall remain on for one 
complete thermostat ``cut-off/cut-on'' of the electrical resistance 
heaters or gas burners after the test block temperature has 
increased 234[emsp14][deg]F (130 [deg]C) above its initial 
temperature.
    3.1.1.1 Self-cleaning operation of a conventional oven. 
Establish the test conditions set forth in section 2, Test 
Conditions, of this Appendix. Turn off the gas flow to the 
conventional cooking top. The temperature of the conventional oven 
shall be its normal nonoperating temperature as defined in section 
1.12 and described in section 2.6 of this Appendix. Then set the 
conventional oven's self-cleaning process in accordance with the 
manufacturer's instructions. If the self-cleaning process is 
adjustable, use the average time recommended by the manufacturer for 
a moderately soiled oven.
    3.1.1.2 Conventional oven standby mode and off mode power. 
Establish the standby mode and off mode testing conditions set forth 
in section 2, Test Conditions, of this Appendix. For conventional 
ovens that take some time to enter a stable state from a higher 
power state as discussed in Section 5, Paragraph 5.1, Note 1 of IEC 
62301 (Second Edition) (incorporated by reference; see Sec.  430.3), 
allow sufficient time for the conventional oven to reach the lower 
power state before proceeding with the test measurement. Follow the 
test procedure as specified in Section 5, Paragraph 5.3.2 of IEC 
62301 (Second Edition) for testing in each possible mode as 
described in 3.1.1.2.1 and 3.1.1.2.2. For units in which power 
varies as a function of displayed time in standby mode, either: (1) 
Set the clock time to 3:23 at the end of the stabilization period 
specified in Section 5, Paragraph 5.3 of IEC 62301 (First Edition), 
and use the average power approach described in Section 5, Paragraph 
5.3.2(a) of IEC 62301 (First Edition), but with a single test period 
of 10 minutes +0/-2 sec after an additional stabilization period 
until the clock time reaches 3:33; or (2) at any starting clock 
time, allow a stabilization period as described in Section 5, 
Paragraph 5.3 of IEC 62301 (First Edition), and use the average 
power approach described in Section 5, Paragraph 5.3.2(a) of IEC 
62301 (First Edition), but with a single test period of 12 hours +0/
-30 sec. Testing may be conducted using either a 12-hour test, a 10-
minute test, or both tests; however, if a manufacturer elects to 
perform both tests on a unit, the manufacturer may only use the 
results from one of the tests (i.e., the 12-hour test or the 10-
minute test) as the test results for that unit. Results of the 10-
minute test that are within 2 percent of the 12-hour 
test are deemed to be representative of average energy use.
    3.1.1.2.1 If the conventional oven has an inactive mode, as 
defined in section 1.11 of this Appendix, measure and record the 
average inactive mode power of the conventional oven, 
PIA, in watts.
    3.1.1.2.2 If the conventional oven has an off mode, as defined 
in section 1.13 of this Appendix, measure and record the average off 
mode power of the conventional oven, POM, in watts.
    3.1.2 Conventional cooking top. Establish the test conditions 
set forth in section 2, Test Conditions, of this Appendix. Turn off 
the gas flow to the conventional oven(s), if so equipped. The 
temperature of the conventional cooking top shall be its normal 
nonoperating temperature as defined in section 1.12 and described in 
section 2.6 of this Appendix. Set the test block in the center of 
the surface unit under test. The small test block, W2, 
shall be used on electric surface units of 7 inches (178 mm) or less 
in diameter. The large test block, W3, shall be used on 
electric surface units over 7 inches (178 mm) in diameter and on all 
gas surface units. Turn on the surface unit under test and set its 
energy input rate to the maximum setting. When the test block 
reaches 144[emsp14][deg]F (80 [deg]C) above its initial test block 
temperature, immediately reduce the energy input rate to 255 percent of the maximum energy input rate. After 150.1 minutes at the reduced energy setting, turn off the 
surface unit under test.
    3.1.2.1 Conventional cooking top standby mode and off mode 
power. Establish the standby mode and off mode testing conditions 
set forth in section 2, Test Conditions, of this Appendix. For 
conventional cooktops that take some time to enter a stable state 
from a higher power state as discussed in Section 5, Paragraph 5.1, 
Note 1 of IEC 62301 (Second Edition) (incorporated by reference; see 
Sec.  430.3), allow sufficient time for the conventional cooking top 
to reach the lower power state before proceeding with the test 
measurement. Follow the test procedure as specified in Section 5, 
Paragraph 5.3.2 of IEC 62301 (Second Edition) for testing in each 
possible mode as described in sections 3.1.2.1.1 and 3.1.2.1.2 of 
this Appendix. For units in which power varies as a function of 
displayed time in standby mode, either: (1) Set the clock time to 
3:23 at the end of the stabilization period specified in Section 5, 
Paragraph 5.3 of IEC 62301 (First Edition), and use the average 
power approach described in Section 5, Paragraph 5.3.2(a) of IEC 
62301 (First Edition), but with a single test period of 10 minutes 
+0/-2 sec after an additional stabilization period until the clock 
time reaches 3:33; or (2) at any starting clock time, allow a 
stabilization period as described in Section 5, Paragraph 5.3 of IEC 
62301 (First Edition), and use the average power approach described 
in Section 5, Paragraph 5.3.2(a) of IEC 62301 (First Edition), but 
with a single test period of 12 hours +0/-30 sec. Testing may be 
conducted using either a 12-hour test, a 10-minute test, or both 
tests; however, if a manufacturer elects to perform both tests on a 
unit, the manufacturer may only use the results from one of the test 
(i.e., the 12-hour test or the 10-minute test) as the test results 
for that unit. Results of the 10-minute test that are within 2 percent of the 12-hour test are deemed to be representative 
of average energy use.

power state as discussed in Section 5, Paragraph 5.1, Note 1 of IEC 
62301 (Second Edition) (incorporated by reference; see Sec.  430.3),

62301 (Second Edition) for testing in each possible mode as 
described in sections 3.1.3.1 and 3.1.3.2 of this Appendix. For

IEC 62301 (First Edition), and use the average power approach 
described in Section 5, Paragraph 5.3.2(a) of IEC 62301 (First

conducted using either a 12-hour test, a 10-minute test, or both 
tests; however, if a manufacturer elects to perform both tests on a 
unit, the manufacturer may only use the results from one of the test 
(i.e., the 12-hour test or the 10-minute test) as the test results 
for that unit. Results of the 10-minute test that are within 2 percent of the 12-hour test are

combined component is the sum of the annual useful cooking energy 
output of each component divided by the sum of the total annual

    9. Appendix X to subpart B of part 430 is revised to read as 
follows:

Appendix X to Subpart B of Part 430--Uniform Test Method for Measuring 
the Energy Consumption of Dehumidifiers

    Note: The procedures and calculations that refer to standby mode 
and off mode energy consumption (i.e., sections 3.2, 3.2.1 through 
3.2.4, 4.2, 4.2.1 through 4.2.4, 5.1, and 5.2 of this Appendix X) 
need not be performed to determine compliance with energy 
conservation standards for dehumidifiers at this time. However, any 
representation related to standby mode and off mode energy 
consumption of these products made after (date 180 days after date 
of publication of the test procedure final rule in the Federal 
Register) must be based upon results generated under this test 
procedure, consistent with the requirements of 42 U.S.C. 6293(c)(2). 
Upon the compliance date for any energy conservation standards that 
incorporate standby mode and off mode energy consumption, compliance 
with the applicable provisions of this test procedure will be 
required.

1. Scope

    This Appendix covers the test requirements used to measure the 
energy performance of dehumidifiers.

[[Page 49087]]

2. Definitions

    a. ANSI/AHAM DH-1 means the test standard published by the 
American National Standards Institute and the Association of Home 
Appliance Manufacturers, titled ``Dehumidifiers,'' ANSI/AHAM DH-1-
2008, (incorporated by reference; see Sec.  430.3).
    b. Active mode means a mode in which a dehumidifier is connected 
to a mains power source, has been activated, and is performing the 
main functions of removing moisture from air by drawing moist air 
over a refrigerated coil using a fan, or circulating air through 
activation of the fan without activation of the refrigeration 
system.
    c. Bucket full/removed mode means a standby mode in which the 
dehumidifier has automatically powered off its main function by 
detecting when the water bucket is full or has been removed.
    d. Energy factor for dehumidifiers means a measure of energy 
efficiency of a dehumidifier calculated by dividing the water 
removed from the air by the energy consumed, measured in liters per 
kilowatt-hour (L/kWh).
    e. IEC 62301 means the test standard published by the 
International Electrotechnical Commission, titled ``Household 
electrical appliances--Measurement of standby power,'' Publication 
62301 (Edition 2.0 2011-01) (incorporated by reference; see Sec.  
430.3).
    f. Inactive mode means a standby mode that facilitates the 
activation of active mode by remote switch (including remote 
control), internal sensor, or timer, or that provides continuous 
status display.
    g. Off mode means a mode in which the dehumidifier is connected 
to a mains power source and is not providing any active mode or 
standby mode function, and where the mode may persist for an 
indefinite time. An indicator that only shows the user that the 
dehumidifier is in the off position is included within the 
classification of an off mode.
    h. Off-cycle mode means a standby mode in which the 
dehumidifier:
    (1) Has cycled off its main function by humidistat or humidity 
sensor;
    (2) Does not have its fan or blower operating; and
    (3) Will reactivate the main function according to the 
humidistat or humidity sensor signal.
    i. Product capacity for dehumidifiers means a measure of the 
ability of the dehumidifier to remove moisture from its surrounding 
atmosphere, measured in pints collected per 24 hours of continuous 
operation.
    j. Standby mode means any modes where the dehumidifier is 
connected to a mains power source and offers one or more of the 
following user-oriented or protective functions which may persist 
for an indefinite time:
    (1) To facilitate the activation of other modes (including 
activation or deactivation of active mode) by remote switch 
(including remote control), internal sensor, or timer;
    (2) Continuous functions, including information or status 
displays (including clocks) or sensor-based functions. A timer is a 
continuous clock function (which may or may not be associated with a 
display) that provides regular scheduled tasks (e.g., switching) and 
that operates on a continuous basis.

3. Test Apparatus and General Instructions

    3.1 Active mode. The test apparatus and instructions for testing 
dehumidifiers shall conform to the requirements specified in Section 
3, ``Definitions,'' Section 4, ``Instrumentation,'' and Section 5, 
``Test Procedure,'' of ANSI/AHAM DH-1 (incorporated by reference, 
see Sec.  430.3). Record measurements at the resolution of the test 
instrumentation. Round off calculations to the same number of 
significant digits as the previous step. Round the final minimum 
energy factor value to two decimal places as follows:
    (i) A fractional number at or above the midpoint between two 
consecutive decimal places shall be rounded up to the higher of the 
two decimal places; or
    (ii) A fractional number below the midpoint between two 
consecutive decimal places shall be rounded down to the lower of the 
two decimal places.
    3.2 Standby mode and off mode.
    3.2.1 Installation requirements. For the standby mode and off 
mode testing, the dehumidifier shall be installed in accordance with 
Section 5, Paragraph 5.2 of IEC 62301 (incorporated by reference, 
see Sec.  430.3), disregarding the provisions regarding batteries 
and the determination, classification, and testing of relevant 
modes.

    3.2.2.1 Electrical supply. For the standby mode and off mode 
testing, maintain the electrical supply voltage and frequency 
indicated in Section 7.1.3, ``Standard Test Voltage,'' of ANSI/AHAM 
DH-1, (incorporated by reference, see Sec.  430.3). The electrical 
supply frequency shall be maintained  1 percent.
    3.2.2.2 Supply voltage waveform. For the standby mode and off 
mode testing, maintain the electrical supply voltage waveform 
indicated in Section 4, Paragraph 4.3.2 of IEC 62301, (incorporated 
by reference; see Sec.  430.3).
    3.2.3 Standby mode and off mode watt meter. The watt meter used 
to measure standby mode and off mode power consumption shall meet 
the requirements specified in Section 4, Paragraph 4.4 of IEC 62301 
(incorporated by reference, see Sec.  430.3).
    3.2.4 Standby mode and off mode ambient temperature. For standby 
mode and off mode testing, maintain room ambient air temperature 
conditions as specified in Section 4, Paragraph 4.2 of IEC 62301 
(incorporated by reference; see Sec.  430.3).

(incorporated by reference; see Sec.  430.3), allow sufficient time 
for the dehumidifier to reach the lower power state before 
proceeding with the test measurement. Follow the test procedure 
specified in Section 5, Paragraph 5.3.2 of IEC 62301 for testing in 
each possible mode as described in sections 4.2.1 through 4.2.4 of 
this Appendix.
