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 


jlentini on DSK4TPTVN1PROD with PROPOSALS2
Federal Register / Vol. 76, No. 217 / Wednesday, November 9, 2011 / Proposed Rules 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 °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 

http://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 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

1A notation in the form ‘‘AHAM, No. 14 at p. 5’’ 

identifies a 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. 

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. (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 

‘‘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 


jlentini on DSK4TPTVN1PROD with PROPOSALS2
Federal Register / Vol. 76, No. 217 / Wednesday, November 9, 2011 / Proposed Rules 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 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 

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 


jlentini on DSK4TPTVN1PROD with PROPOSALS2
69874 Federal Register / Vol. 76, No. 217 / Wednesday, November 9, 2011 / Proposed Rules 

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/ 


jlentini on DSK4TPTVN1PROD with PROPOSALS2
Federal Register / Vol. 76, No. 217 / Wednesday, November 9, 2011 / Proposed Rules 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 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’’, 

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 


jlentini on DSK4TPTVN1PROD with PROPOSALS2
69876 Federal Register / Vol. 76, No. 217 / Wednesday, November 9, 2011 / Proposed Rules 

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

2A searchable database of certified small 

businesses is available online at: http://

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: http:// 

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. 

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 

increasing wash time until the setting is 

reached. 

* * * * * 

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. Calculation of Derived Results From Test 

Measurements. 

* * * * * 

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: 

e = Nominal gas or oil water heater efficiency 

= 0.75. 

HET = As defined in 4.1.3.

material that are 12 ± 1⁄4 inches by 12 ± 1⁄4

inches (30.5 ± 0.6 cm by 30.5 ± 0.6 cm) and 

have been hemmed to 10 ± 1⁄4 inches by 10 

± 1⁄4 inches (25.4 ± 0.6 cm by 25.4 ± 0.6 cm) 

before washing. The energy stuffer cloth shall 

be clean and shall not be used for more than 

60 test runs (after preconditioning as 

specified in section 2.6.3 of this appendix). 

All energy stuffer cloth must be permanently 

marked identifying the lot number of the 

material. Mixed lots of material shall not be 

used for testing the clothes washers. 

2.6.3 Preconditioning of Test Cloths. The 

new test cloths, including energy test cloths 

and energy stuffer cloths, shall be preconditioned in a clothes washer in the 

following manner: 

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 


jlentini on DSK4TPTVN1PROD with PROPOSALS2
69884 Federal Register / Vol. 76, No. 217 / Wednesday, November 9, 2011 / Proposed Rules 

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). 

2.6.4 Energy test cloth material. The 

energy test cloths and energy stuffer cloths 

shall be made from fabric meeting the 

following specifications. The material should 

come from a roll of material with a width of 

approximately 63 inches and approximately 

500 yards per roll. However, other sizes may 

be used if they fall within the specifications. 

2.6.4.1 Nominal fabric type. Pure finished 

bleached cloth made with a momie or granite 

weave, which is nominally 50 percent cotton 

and 50 percent polyester. 

2.6.4.2 The fabric weight specification 

shall be 5.60 ± 0.25 ounces per square yard 

(190.0 ± 8.4 g/m2). 

2.6.4.3 The thread count shall be 65 × 57

shall each have fiber content of 50 percent ±4 

percent cotton, with the balance being 

polyester, and be open end spun, 15/1 ± 5 

percent cotton count blended yarn. 

2.6.4.5 Water repellent finishes, such as 

fluoropolymer stain resistant finishes shall 

not be applied to the test cloth. The absence 

of such finishes shall be verified by: 

2.6.4.5.1 AATCC Test Method 118–2007, 

(incorporated by reference; see § 430.3), for 

each new lot of test cloth (when purchased 

from the mill) to confirm the absence of 

Scotchguard TM or other water repellent 

finish (required scores of ‘‘D’’ across the 

board). 

2.6.4.5.2 AATCC Test Method 79–2010, 

(incorporated by reference; see § 430.3), for 

each new lot of test cloth (when purchased 

from the mill) to confirm the absence of 

Scotchguard TM or other water repellent 

finish (time to absorb one drop should be on 

the order of 1 second). 

2.6.4.6 The moisture absorption and 

retention shall be evaluated for each new lot 

of test cloth by the Standard Extractor 

Remaining Moisture Content (RMC) Test 

specified in section 2.6.5 of this appendix. 

2.6.4.6.1 Repeat the Standard Extractor 

RMC Test in section 2.6.5 of this appendix 

three times. 

2.6.4.6.2 An RMC correction curve shall 

be calculated as specified in section 2.6.6 of 

this appendix. 

2.6.4.7 The maximum shrinkage after 

preconditioning shall not be more than 5 

percent on the length and width. Measure per 

AATCC Test Method 135–2010, 

(incorporated by reference; see § 430.3). 

2.6.5 Standard Extractor RMC Test 

Procedure. The following procedure is used 

to evaluate the moisture absorption and 

retention characteristics of a lot of test cloth 

by measuring the RMC in a standard 

extractor at a specified set of conditions. 

Table 2.6.5 of this appendix is the matrix of 

test conditions. When this matrix is repeated 

3 times, a total of 60 extractor RMC test runs 

are required. For the purpose of the extractor 

RMC test, the test cloths may be used for up 

to 60 test runs (after preconditioning as 

specified in section 2.6.3 of this appendix).

2.6.5.1 The standard extractor RMC tests 

shall be run in a North Star Engineered 

Products Inc. (formerly Bock) Model 215 

extractor (having a basket diameter of 19.5 

inches, length of 12 inches, and volume of 

2.1 ft 3), with a variable speed drive (North 

Star Engineered Products, P.O. Box 5127, 

Toledo, OH 43611) or an equivalent extractor 

with same basket design (i.e. diameter, 

length, volume, and hole configuration) and 

variable speed drive. 

2.6.5.2 Test Load. Test cloths shall be 

preconditioned in accordance with section 

2.6.3 of this appendix. The load size shall be 

8.4 lbs, consistent with section 3.8.1 of this 

appendix. 

2.6.5.3 Procedure. 

2.6.5.3.1 Record the ‘‘bone-dry’’ weight of 

the test load (WI). 

2.6.5.3.2 Prepare the test load for soak by 

grouping four test cloths into loose bundles. 

Bundles are created by hanging four cloths 

vertically from one corner and loosely 

wrapping the test cloth onto itself to form the 

bundle. Bundles are then placed into the 

water for soak. Eight to nine bundles will be 

formed depending on the test load. The ninth 

bundle may not equal four cloths but can 

incorporate energy stuffer cloths to help 

offset the size difference. 

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. 

2.6.5.3.9 It is not necessary to dry the test 

load in between extraction runs. However, 

the bone dry weight shall be checked after 

every 12 extraction runs to make sure the 

bone dry weight is within tolerance (8.4 ± 0.1 

lb). 

2.6.5.3.10 The RMC of the test load shall 

be measured at five g levels: 100 g, 200 g, 350 

g, 500 g, and 650 g, using two different spin 

times at each g level: 4 minutes and 15 

minutes. 

2.6.5.4 Repeat section 2.6.5.3 of this 

appendix using soft (< 17 ppm) water at 60 

°F ± 5 °F. 

2.6.6 Calculation of RMC correction 

curve. 

2.6.6.1 Average the values of 3 test runs 

and fill in Table 2.6.5 of this appendix. 

Perform a linear least-squares fit to relate the 

standard RMC (RMCstandard) values (shown in 

Table 2.6.6.1 of this appendix) to the values 

measured in section 2.6.5 of this appendix: 

(RMCcloth): RMCstandard ¥ A × RMCcloth + B 

where A and B are coefficients of the linear 

least-squares fit.

2.6.6.2 Perform an analysis of variance 

test using two factors, spin speed and lot, to 

check the interaction of speed and lot. Use 

the values from Table 2.6.5 and Table 2.6.6.1 

of this appendix in the calculation. The ‘‘P’’ 

value in the variance analysis shall be greater 

than or equal to 0.1. If the ‘‘P’’ value is less 

than 0.1, the test cloth is unacceptable. ‘‘P’’ 

is a theoretically based probability of 

interaction based on an analysis of variance. 

2.6.7 Application of the RMC correction 

curve. 

2.6.7.1 Using the coefficients A and B 

calculated in section 2.6.6.1 of this appendix: 

RMCcorr = A × RMC + B 

2.6.7.2 Substitute RMCcorr values in 

calculations in section 3.8 of this appendix. 

2.7 Test Load Sizes. Maximum, 

minimum, and, when required, average test 

load sizes shall be determined using Table 

5.1 of this appendix and the clothes 

container capacity as measured in sections 

3.1.1 through 3.1.5 of this appendix. Test 

loads shall consist of energy test cloths, 

except that adjustments to the test loads to 

achieve proper weight can be made by the 

use of energy stuffer cloths with no more 

than 5 stuffer cloths per load. 

2.8 Use of Test Loads. Table 2.8 of this 

appendix defines the test load sizes and 

corresponding water fill settings which are to 

be used when measuring water and energy 

consumptions. Adaptive water fill control 

system and manual water fill control system 

are defined in section 1 of this appendix:

2.8.1 The test load sizes to be used to 

measure RMC are specified in section 3.8.1 

of this appendix. 

2.8.2 Test loads for energy and water 

consumption measurements shall be bone 

dry prior to the first cycle of the test, and 

dried to a maximum of 104 percent of bone 

dry weight for subsequent testing. 

2.8.3 Load the energy test cloths by 

grasping them in the center, shaking them to 

hang loosely and then put them into the 

clothes container prior to activating the 

clothes washer. 

2.9 Pre-conditioning. 

2.9.1 Non-water-heating clothes washer. 

If the clothes washer has not been filled with 

water in the preceding 96 hours, precondition it by running it through a cold 

rinse cycle and then draining it to ensure that 

the hose, pump, and sump are filled with 

water. 

2.9.2 Water-heating clothes washer. If the 

clothes washer has not been filled with water 

in the preceding 96 hours, or if it has not 

been in the test room at the specified ambient 

conditions for 8 hours, pre-condition it by 

running it through a cold rinse cycle and 

then draining it to ensure that the hose, 

pump, and sump are filled with water. 

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 

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, 

maintain room ambient air temperature 

conditions as specified in Section 4, 

Paragraph 4.2 of IEC 62301 (incorporated by 

reference; see § 430.3). 

2.11.2 Water-heating clothes washer. 

Maintain the test room ambient air 

temperature at 75 °F ± 5 °F (23.9 °C ± 2.8 °C). 

For combined low-power mode testing, 

maintain room ambient air temperature 

conditions as specified in Section 4, 

Paragraph 4.2 of IEC 62301 (incorporated by 

reference; see § 430.3). 

2.12 Bone dryer temperature. The dryer 

used for bone drying must heat the test cloth 

and energy stuffer cloths above 210 °F (99 

°C). 

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, 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 

cycle setting. 

Measure each cycle setting’s electrical 

energy consumption (EB) and hot water 

consumption (HB). Calculate the total energy 


jlentini on DSK4TPTVN1PROD with PROPOSALS2
69886 Federal Register / Vol. 76, No. 217 / Wednesday, November 9, 2011 / Proposed Rules 

consumption for each cycle setting (ETB), as 

follows: 

ETB = EB + (HB × T × 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) 

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 

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 

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 


jlentini on DSK4TPTVN1PROD with PROPOSALS2
Federal Register / Vol. 76, No. 217 / Wednesday, November 9, 2011 / Proposed Rules 69893 

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 

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 

conform to the definition of the energy test 

cycle. 

Calculate: 

T = The total number of energy test cycles 

run during the field test. 

Ta = The total number of adaptive control 

energy test cycles. 

Tm = The total number of manual control 

energy test cycles. 

The percentage weighting factors: 

Pa = (Ta/T) × 100 (the percentage weighting 

for adaptive control selection) 

Pm = (Tm/T) × 100 (the percentage weighting 

for manual control selection) 

Energy consumption (HET, MET, and 

DE) and water consumption (QT), values 

calculated in section 4 of this appendix 

for the manual and adaptive modes, 

should be combined using Pa and Pm as 

the weighting factors.
