I. Authority and Background 

Title III of the Energy Policy and 

Conservation Act (42 U.S.C. 6291, et 

seq.; ‘‘EPCA’’ or, ‘‘the Act’’) sets forth a 

variety of provisions designed to 

improve energy efficiency. (All 

references to EPCA refer to the statute 

as amended through the Energy 

Independence and Security Act of 2007 

(EISA 2007), Public Law 110–140 (Dec. 

19, 2007)). Part B of title III (42 U.S.C. 

6291–6309), which was subsequently 

redesignated for editorial reasons as Part 

A on codification in the U.S. Code, 

establishes the ‘‘Energy Conservation 

Program for Consumer Products Other 

Than Automobiles.’’ These include 

residential clothes washers, the subject 

of today’s notice. (42 U.S.C. 6292(a)(7)) 

Under EPCA, this program consists 

essentially of four parts: (1) Testing, (2) 

labeling, (3) Federal energy conservation 

standards, and (4) certification and 

enforcement procedures. The testing 

requirements consist of test procedures 

that manufacturers of covered products 

must use (1) As the basis for certifying 

to DOE that their products comply with 

the applicable energy conservation

1Because appendix J applies only to clothes 

washers manufactured before January 1, 2004, 

appendix J is now obsolete. 10 CFR 430 appendix 

J1. 

2 IEC standards are available online at http:// 

www.iec.ch. 

3EISA 2007 also amended EPCA, in relevant part, 

to revise the energy conservation standards for 

residential clothes washers. The revised standards 

established a maximum water consumption factor 

(WF) of 9.5, effective January 1, 2011. EISA 2007 

further required that DOE publish a final rule no 

later than December 31, 2011 determining whether 

to amend the standards in effect for clothes washers 

manufactured on or after January 1, 2015. (42 U.S.C. 

6295(g)(9)) DOE is also required to consider standby 

and off mode standards for residential clothes 

washers. (42 U.S.C. 6295(gg)(2)(C). 

standards adopted under EPCA, and (2) 

for making representations about the 

efficiency of those products. Similarly, 

DOE must use these test requirements to 

determine whether the products comply 

with any relevant standards 

promulgated under EPCA. 

General Test Procedure Rulemaking 

Process 

Under 42 U.S.C. 6293, EPCA sets forth 

the criteria and procedures DOE must 

follow when prescribing or amending 

test procedures for covered products. 

EPCA provides in relevant part that any 

test procedures prescribed or amended 

under this section must 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 not be unduly 

burdensome to conduct. (42 U.S.C. 

6293(b)(3)) 

In addition, if DOE determines that a 

test procedure amendment is warranted, 

it must publish proposed test 

procedures and offer the public an 

opportunity to present oral and written 

comments on them. (42 U.S.C. 

6293(b)(2)) Finally, in any rulemaking to 

amend a test procedure, DOE must 

determine to what extent, if any, the 

proposed test procedure would alter the 

measured energy efficiency of any 

covered product as determined under 

the existing test procedure. (42 U.S.C. 

6293(e)(1)) If DOE determines that the 

amended test procedure would alter the 

measured efficiency of a covered 

product, DOE must amend the 

applicable energy conservation standard 

accordingly. (42 U.S.C. 6293(e)(2)) 

DOE Test Procedure at Appendix J1 

The DOE test procedure for clothes 

washers currently being manufactured 

is found at 10 CFR part 430, subpart B, 

appendix J1. DOE adopted appendix J1 

in a 1997 final rule (hereinafter referred 

to as the August 1997 Final Rule) to 

correct for changes in consumer habits 

that resulted in an overstatement of 

average annual energy consumption 

when using the methods specified in 

appendix J. 62 FR 45508 (Aug. 27, 

1997). DOE added appendix J1, rather 

than amending appendix J, to 

accommodate continued use of 

appendix J until DOE amended the 

residential clothes washer conservation 

standards to reference the new appendix 

J1.1 On January 12, 2001, DOE 

published a final rule (hereinafter 

referred to as the January 2001 Final 

Rule), to amend the energy conservation 

standards for residential clothes 

washers. The January 2001 Final Rule 

references the efficiency metrics as 

defined in appendix J1. 66 FR 3314. Use 

of the amended J1 test procedure was 

required to demonstrate compliance 

with these amended energy 

conservation standards as of January 1, 

2004. Since 1997, DOE has amended the 

test procedure in appendix J1 three 

times, twice substantively to address 

test cloth correlation procedures, and 

once to correct the introductory note. 63 

FR 16669 (Apr. 6, 1998); 66 FR 3314, 

3330 (Jan. 12, 2001); 68 FR 62198, 62204 

(Oct. 31, 2003). 

The test procedure at appendix J1 

includes provisions for determining the 

modified energy factor (MEF) for clothes 

washers, which is a function of the total 

energy used for each cubic foot (ft3) of 

clothes washer capacity. The test 

procedure measures the total energy 

consumption of the clothes washer and 

provides for calculation of the 

remaining moisture content (RMC) of 

the clothes at the completion of the 

machine’s full cycle. The test procedure 

at appendix J1 does not address energy 

use in the standby or off modes. 

DOE Test Procedure Updates: Authority 

and Regulatory Background 

EPCA requires DOE to review its test 

procedures at least once every seven 

years to determine whether 

amendments are warranted. (42 U.S.C. 

6293(b)(1)) This rulemaking satisfies 

EPCA’s periodic review requirement. 

The Energy Independence and 

Security Act of 2007 (EISA 2007), Public 

Law No. 110–140 also amended EPCA 

to require DOE to amend its test 

procedures to integrate measures of 

standby mode and off mode energy 

consumption into the overall energy 

efficiency, energy consumption, or other 

energy descriptor for each covered 

product unless the current test 

procedure already fully accounts for and 

incorporates standby and off mode 

energy consumption or such integration 

is technically infeasible. If an integrated 

test procedure is technically infeasible, 

DOE must prescribe a separate standby 

mode and off mode energy use test 

procedure for the covered product, if 

technically feasible. (42 U.S.C. 

6295(gg)(2)(A)) Any such amendment 

must consider the most current versions 

of IEC Standard 62301 and IEC Standard 

62087, ‘‘Methods of measurement for 

the power consumption of audio, video, 

and related equipment.’’ 2

In evaluating amendments to its test 

procedure for clothes washers, DOE 

considered input from the public 

received in its separate rulemaking 

proceeding to consider amendments to 

the energy conservation standards 

applicable to residential clothes 

washers.3 On August 28, 2009, DOE 

published a notice in the Federal 

Register announcing the availability of 

a framework document in its 

rulemaking to consider amended energy 

conservation standards for residential 

clothes washers (hereafter the August 

2009 framework document). 74 FR 

44306. In the August 2009 framework 

document, DOE requested comments on 

revising the clothes washer test 

procedure. DOE also held a public 

meeting on September 21, 2009 

(hereinafter referred to as the September 

2009 public meeting) to discuss the 

issues presented in the framework 

document, including issues related to 

the test procedure. 

DOE received comments in response 

to the August 2009 framework 

document stating that it should consider 

changes to the active mode test 

procedure for clothes washers. As a 

result, in addition to proposing 

amendments to its test procedure to 

include measures for standby and off 

mode power consumption, DOE 

proposed to address issues regarding the 

active mode provisions of the test 

procedure. As discussed in more detail 

below, the proposals were set forth in a 

notice of proposed rulemaking issued 

on September 21, 2010 (75 FR 57556) 

(hereinafter referred to as the September 

2010 NOPR) and are being refined in 

this SNOPR. 

In the September 2010 NOPR, DOE 

proposed a number of revisions and 

additions to the test procedure at 

appendix J1, including: (1) 

Incorporating standby and off mode 

power consumption into a combined 

energy metric; (2) addressing 

technologies not covered by the 

appendix J1 test procedure, such as 

steam wash cycles and self-clean cycles; 

(3) revising the number of annual wash 

cycles; (4) updating use factors; (5) 

revising the procedures and 

specifications for test cloth; (6) 

redefining the appropriate water fill

49240 Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules 

4EISA 2007 directs DOE to also consider IEC 

Standard 62087 when amending its test procedure 

to include standby mode and off mode energy 

consumption. See 42 U.S.C. 6295(gg)(2)(A). DOE 

has considered IEC Standard 62087, which 

addresses the methods of measuring the power 

consumption of audio, video, and related 

equipment, and determined that it is not relevant 

to this proposal. 

level for the capacity measurement 

method; (7) establishing a new measure 

of water consumption; and (8) revising 

the definition of the energy test cycle. 

DOE requested comment on the 

proposals in the September 2010 NOPR 

and held a public meeting on October 

28, 2010 (hereinafter referred to as the 

October 2010 public meeting) to discuss 

the issues presented. 

The principal test procedure issues on 

which interested parties commented 

included: (1) The referenced version of 

IEC Standard 62301; (2) mode 

definitions; (3) inclusion of steam and 

self-clean cycles; (4) measurement of 

delay start and cycle finished mode; (5) 

calculation of annual energy use; (6) test 

cloth specifications; (7) usage patterns, 

in particular annual use cycles, wash 

temperatures, and load sizes, including 

a potential bias in favor of large-capacity 

clothes washers; and (8) test burden. 

II. Summary of the Supplemental 

Notice of Proposed Rulemaking 

The following paragraphs summarize 

the changes and additions to the 

September 2010 NOPR that DOE 

proposes in today’s SNOPR. In the 

regulatory text set forth at the end of 

this SNOPR, DOE sets forth the 

proposed regulatory text from the 

September 2010 NOPR, as amended by 

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 September 2010 NOPR. 75 FR 57556 

(Sept. 21, 2010). 

A. Standby Mode and Off Mode 

In the September 2010 NOPR, DOE 

proposed amendments to its clothes 

washer test procedure including 

incorporating by reference specific 

provisions from IEC Standard 62301, 

First Edition 2005–06 (‘‘IEC Standard 

62301 (First Edition)’’ or ‘‘First 

Edition’’) regarding test conditions and 

test procedures for measuring standby 

mode and off mode power consumption. 

75 FR 57556, 57560 (Sept. 21, 2010). 

DOE also proposed to incorporate the 

definitions of ‘‘active mode,’’ ‘‘standby 

mode,’’ and ‘‘off mode’’ that were based 

on the definitions for those terms 

provided in the most current draft at 

that time of an updated version of IEC 

Standard 62301 (the Committee Draft for 

Vote, or ‘‘CDV’’ version). Id. at 57560– 

62. Further, DOE proposed to include 

additional language that would clarify 

the application of clauses from IEC 

Standard 62301 (First Edition) for 

measuring standby mode and off mode 

power consumption.4 Id. at 57562–63. 

In response to the September 2010 

NOPR, commenters suggested that the 

draft updated version of IEC Standard 

62301 would improve the mode 

definitions and testing methodology. 

The IEC published IEC Standard 62301, 

Edition 2.0 2011–01 (‘‘IEC Standard 

62301 (Second Edition)’’ or ‘‘Second 

Edition’’) on January 27, 2011. DOE has 

reviewed this updated test procedure 

and believes that it improves some 

measurements of standby mode and off 

mode energy use. Accordingly, DOE 

proposes in today’s SNOPR to 

incorporate certain provisions of the IEC 

Standard 62301 (Second Edition), along 

with clarifying language, into the new 

clothes washer test procedure. DOE also 

proposes to incorporate into the new 

test procedure definitions of ‘‘active 

mode,’’ ‘‘standby mode,’’ and ‘‘off 

mode’’ based on the definitions 

provided in IEC Standard 62301 Second 

Edition. In addition, DOE proposes to 

incorporate measures of energy 

consumption associated with delay start 

and cycle finished modes. Although 

these modes would be considered part 

of active mode, the proposed 

measurements and calculations for 

standby and off mode power 

consumption would include the energy 

use in such modes in a simplified 

approach to account for energy use 

associated with all low-power modes by 

means of a single power measurement. 

Finally, DOE proposes in today’s 

SNOPR to revise the calculations for 

per-cycle energy use and annual energy 

cost to incorporate non-active washing 

mode energy consumption. (42 U.S.C. 

6293(b)(3); 42 U.S.C. 6291(4), (7). 

B. Current Usage Patterns and 

Capabilities 

The proposed test procedure would 

update certain values from the existing 

test procedure to reflect current usage 

patterns and capabilities. DOE received 

multiple comments on this issue in 

response to the August 2009 framework 

document, and reviewed current 

consumer data from surveys conducted 

in 2004 and 2005 to propose updates in 

the September 2010 NOPR. Based on 

this information and comments received 

in response to the September 2010 

NOPR, DOE is proposing additional 

amendments to the load adjustment 

factor in today’s SNOPR. DOE is also 

proposing in this SNOPR to update the 

test load sizes specified in appendix J1 

to reflect the same test load sizes 

previously proposed for appendix J2, 

allowing for testing of large-capacity 

clothes washers to demonstrate 

compliance with existing energy 

conservation standards. 

C. Additional Proposals 

The revised clothes washer test 

procedure amendments DOE is 

proposing in today’s SNOPR would 

update the procedure to clarify the 

existing methods for determining the 

energy test cycle, setting the wash time 

for certain clothes washers, using the 

most current AHAM Standard detergent, 

and clarifying the definition of ‘‘cold 

wash’’ for clothes washers that offer 

both ‘‘cold wash’’ and ‘‘tap cold wash’’ 

settings. DOE is also proposing the 

following amendments in today’s 

SNOPR: Correcting the definition of 

cold rinse in appendix J1; deleting the 

redundant sections 2.6.1.1–2.6.1.2.4 in 

appendix J1; and correcting the 

calculations proposed in the September 

2010 NOPR for per-cycle self-clean 

water consumption. 

III. Discussion 

A. Use of Proposed Test Procedure 

The amended test procedures in 10 

CFR part 430 subpart B appendix J1 and 

appendix J2 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. 

B. Newly Proposed Standby Mode, Off 

Mode, and Active Mode Test Procedure 

Provisions 

1. Incorporating by Reference IEC 

Standard 62301 Edition 2.0 for 

Measuring Standby Mode and Off Mode 

Power Consumption 

As noted in the September 2010 

NOPR, DOE considered, pursuant to 

EPCA, the most current versions of IEC 

Standard 62301 and IEC Standard 62087 

for measuring power consumption in 

standby mode and off mode. (42 U.S.C. 

6295(gg)(2)(A)) DOE noted that IEC

5All comments on the RFI are available at 

http://www.gc.energy.gov/1705.htm. 

Standard 62301 provides for measuring 

standby power in electrical appliances, 

including clothes washers, and 

therefore, is applicable to the provisions 

included in the new clothes washer test 

procedure. 75 FR 57556, 57560 (Sept. 

21, 2010). DOE also noted that IEC 

Standard 62087, which applies to audio, 

video, and related equipment, is 

inapplicable to this rulemaking, and did 

not propose to include any of its 

provisions in the new test procedure. 

The Northwest Energy Efficiency 

Alliance (NEEA) agreed with DOE’s 

determination that IEC Standard 62301 

is an appropriate reference standard and 

that IEC Standard 62087 is not relevant 

to this rulemaking. (NEEA, No. 12 at 

p. 2). 

DOE proposed in the September 2010 

NOPR to incorporate by reference into 

this test procedure all applicable 

provisions from Sections 4 and 5 of IEC 

Standard 62301 (First Edition). 

Specifically, DOE proposed to 

incorporate, from section 4, (‘‘General 

conditions for measurements’’), 

paragraph 4.2, ‘‘Test room;’’ paragraph 

4.4, ‘‘Supply voltage waveform;’’ 

paragraph 4.5, ‘‘Power measurement 

accuracy;’’ and from section 5, 

(‘‘Measurements’’), paragraph 5.1, 

‘‘General,’’ Note 1; and paragraph 5.3, 

‘‘Procedure.’’ 75 FR 57556, 57560 (Sept. 

21, 2010). These clauses provide test 

conditions and test procedures for 

measuring average standby mode and 

average off mode power consumption. 

With respect to test conditions, section 

4 of IEC Standard 62301 (First Edition) 

provides specifications for the test room 

conditions, supply voltage waveform, 

and power measurement meter 

tolerances to ensure repeatable and 

precise measurements of standby mode 

and off mode power consumption. With 

respect to test procedures, section 5 of 

IEC Standard 62301 (First Edition) 

provides methods for measuring power 

consumption when the power 

measurement is stable and when it is 

unstable. 

DOE also proposed in the September 

2010 NOPR to adopt certain provisions 

from the IEC Standard 62301 Committee 

Draft for Vote (CDV) version (an earlier 

draft version of the IEC 62301 revision), 

as well as the Final Draft International 

Standard (FDIS) version (the draft 

version developed just prior to the 

issuance of the Second Edition). 

Specifically, DOE proposed to adopt the 

30-minute stabilization and 10-minute 

measurement periods as described in 

the CDV version and the mode 

definitions for active, standby and off 

mode as described in the FDIS version. 

DOE noted in the September 2010 

NOPR and at the October 2010 public 

meeting that the IEC was developing an 

updated version of IEC Standard 62301 

(the Second Edition), and interested 

parties commented on the appropriate 

version to use for the measurement of 

standby mode and off mode energy use. 

Comments made at the public meeting 

were predicated upon IEC Standard 

62301 Final Draft International Standard 

(FDIS) being the most current (draft) 

version of the updated standard.

that DOE should reference the most 

current available draft of the Second 

Edition at the time, IEC Standard 62301 

(FDIS). (ALS, No. 10 at p. 1; NEEA, No. 

12 at p. 2; Whirlpool, No. 13 at pp. 1– 

2; AHAM, No. 14 at pp. 2–3; AHAM, 

Public Meeting Transcript, No. 20 at pp. 

21–22; BSH, No. 17 at p. 3; California 

Utilities, No. 18 at p. 1) Whirlpool 

commented that the use of IEC Standard 

62301 (FDIS) would support 

international harmonization and reduce 

manufacturer test burden. (Whirlpool, 

No. 13 at pp. 1–2) AHAM stated that 

combining mode definitions based on 

IEC Standard 62301 (FDIS) with the test 

methods from IEC Standard 62301 (First 

Edition) could be confusing to 

manufacturers, and ignores the intent of 

IEC Standard 62301 (FDIS). AHAM and 

Whirlpool further commented that DOE 

should not choose to reference only 

certain sections of IEC Standard 62301, 

and that the document is meant to be 

used in its entirety. (AHAM, No. 14 at 

p. 3; Whirlpool, No. 13 at p. 3) BSH 

agreed with DOE’s proposal to use IEC 

Standard 62301 as the basis for the 

standby and lower power mode 

definitions, and noted that the most 

recent version of the standard (i.e., IEC 

Standard 62301 (FDIS)) should be 

considered. (BSH, No. 17 at p. 2) 

AHAM also submitted a comment 

supporting the incorporation by 

reference of the Second Edition in 

response to a Request for Information 

(RFI) issued by DOE to implement 

Executive Order 13563, ‘‘Improving 

Regulation and Regulatory Review. (76 

FR 6123, Feb. 3, 2011; AHAM, 4) 5 DOE 

considered this comment in today’s 

SNOPR and, as stated below, is 

proposing to incorporate by reference 

relevant portions of the Second Edition. 

IEC Standard 62301 (Second Edition) 

was issued on January 27, 2011 and is 

now the most current version of IEC 

Standard 62301. DOE has reviewed the 

FDIS and Second Edition versions of 

IEC Standard 62301, and notes that the 

provisions of the Second Edition are 

identical in substance to those of the 

FDIS version. Therefore, DOE interprets 

comments on IEC Standard 62301 

(FDIS) to be equally applicable to IEC 

Standard 62301 (Second Edition). 

DOE notes that IEC Standard 62301 

(Second Edition) is an internationally 

accepted test procedure for measuring 

standby power in residential appliances, 

and that this version provides 

clarification to certain sections as 

compared to the First Edition, as 

discussed in the following paragraphs. 

Section 4, paragraph 4.4 of the Second 

Edition revises the power measurement 

accuracy provisions of the First Edition. 

A more comprehensive specification of 

required accuracy is provided in the 

Second Edition that depends upon the 

characteristics of the power being 

measured. Testers using the Second 

Edition are required to measure the crest 

factor and power factor of the input 

power, and calculate a maximum 

current ratio (MCR). The Second Edition 

then specifies calculations to determine 

permitted uncertainty in MCR. DOE 

notes, however, that the allowable 

uncertainty is the same or less stringent 

than the allowable uncertainty specified 

in the First Edition, depending on the 

value of MCR and the power level being 

measured (see Table III.1 for example), 

so that sufficient accuracy of 

measurements is achieved under a full 

range of possible measured power levels 

without placing undue demands on the 

instrumentation. These power 

measurement accuracy requirements 

were based upon detailed technical 

submissions to the IEC in the 

development of IEC Standard 62301 

(FDIS), which showed that commonly 

used power measurement instruments 

were unable to meet the original 

requirements for certain types of loads. 

Therefore, the test burden associated 

with the additional measurements and 

calculations is offset by the more 

reasonable requirements for testing 

equipment, while maintaining 

acceptable measurement accuracy. For 

these reasons, DOE proposes in today’s 

supplemental notice to incorporate by 


jlentini on DSK4TPTVN1PROD with PROPOSALS3

reference the power equipment 

specifications in section 4, paragraph 

4.4 of IEC Standard 62301 (Second 

Edition).

Additionally, IEC Standard 62301 

(Second Edition) adds certain 

clarifications to the installation and 

setup procedures in section 5, paragraph 

5.2 of the First Edition. The First 

Edition required that the product be 

installed in accordance with the 

manufacturer’s instructions, except if 

those instructions conflict with the 

standby testing, and that if no 

instructions are given, the factory or 

default settings shall be used. IEC 

Standard 62301 (Second Edition) added 

provisions regarding products equipped 

with battery recharging circuits, as well 

as instructions for testing each relevant 

configuration option identified in the 

product’s instructions for use. 

In the September 2010 NOPR, DOE 

proposed that the clothes washer be 

installed according to the 

manufacturer’s instructions, but did not 

propose additional provisions to require 

the use of default settings for testing 

standby energy consumption because it 

did not have information regarding the 

likelihood that consumers will alter the 

default display settings. DOE requested 

comment on the suitability of using the 

manufacturer’s default settings in 

testing standby energy consumption. 75 

FR 57556, 57563 (Sept. 21, 2010). 

AHAM, ALS, NEEA, and Whirlpool 

commented that standby energy 

consumption should be measured at the 

manufacturer default settings. ALS and 

AHAM further stated that if no factory 

default setting is indicated, the clothes 

washer should be tested with the 

settings as shipped from the 

manufacturer. AHAM stated that this 

approach would yield repeatable, 

reproducible results among test 

laboratories. (ALS, No. 10 at p. 1; 

AHAM, No. 14 at pp. 5–6; NEEA, No. 

12 at p. 6; Whirlpool, No. 13 at p. 3) 

DOE agrees with commenters that 

testing a clothes washer for standby 

mode energy use (and, by extension, the 

combined low-power mode energy use) 

at the default setting, or as shipped, if 

a default setting is not indicated, would 

ensure consistency of results test-to-test 

and among test laboratories. Therefore, 

DOE is proposing in today’s SNOPR to 

incorporate by reference, with 

qualification as discussed below, the 

installation instructions in section 5, 

paragraph 5.2 of IEC Standard 62301 

(Second Edition). DOE is not aware of 

any clothes washers with a battery 

recharging circuit. 

Section 5, paragraph 5.2 of IEC 

Standard 62301 (Second Edition) also 

states that, where instructions for use 

provide configuration options, each 

relevant option should be separately 

tested. DOE believes that this 

requirement to separately test each 

configuration option could substantially 

increase test burden and potentially 

conflicts with the requirement within 

the same section to set up the product 

in accordance with the instructions for 

use or, if no such instructions are 

available, to use the factory or default 

settings. Therefore, DOE tentatively 

concludes that the portions of the 

installation instructions in section 5, 

paragraph 5.2 of IEC Standard 62301 

(Second Edition) pertaining to batteries 

and the determination, classification, 

and testing of relevant modes are not 

appropriate for the clothes washer test 

procedure. Accordingly, DOE is 

proposing qualifying language in the 

test procedure amendments in today’s 

SNOPR to disregard those portions of 

the installation instructions. 

The Second Edition also contains 

provisions for the power supply (section 

4.3) and power-measuring instruments 

(section 4.4). Paragraph 4.3.2 requires 

that the value of the harmonic content 

of the voltage supply be recorded during 

the test and reported. As described 

previously, Paragraph 4.4.1 requires the 

instrument to measure the crest factor 

and maximum current ratio. Paragraph 

4.4.3 requires the instrument to be 

capable of measuring the average power 

or integrated total energy consumption 

over any operated-selected time 

interval. DOE is aware of commercially 

available power measurement 

instruments that can perform each of 

these required measurements 

individually. However, DOE is aware 

that certain industry-standard 

instruments, such as the Yokogawa 

WT210/WT230 digital power meter and 

possibly others, are unable to measure 

harmonic content or crest factor while 

measuring average power or total 

integrated energy consumption. DOE is 

concerned that laboratories currently 

using power-measuring instruments 

without this capability would be 

required to purchase, at potentially 

significant expense, additional powermeasuring instruments that are able to 

perform all these measurements 

simultaneously. Therefore, DOE 

proposes that it would be acceptable to 

measure the total harmonic content, 

crest factor, and maximum current ratio 

before and after the actual test 

measurement if the power measuring 

instrument is unable to perform these 

measurements during the actual test 

measurement. DOE requests comment 

on whether this represents an 

acceptable interpretation of the power 

measurement requirements of the 

Second Edition. 

The other changes in the Second 

Edition that relate to the measurement 

of standby mode and off mode power 

consumption involve the measurement 

techniques and specification of the 

stability criteria required to measure 

that power. The Second Edition 

contains more detailed techniques to 

evaluate the stability of the power 

consumption and to measure the power 

consumption for loads with different 

stability characteristics. The user is 

given a choice of measurement 

procedures, including sampling 

methods, average reading methods, and 

a direct meter reading method. DOE 

evaluated these new methods in terms 

of test burden and improvement in 

results as compared to those methods 

proposed in the September 2010 NOPR, 

which were based on IEC Standard 


jlentini on DSK4TPTVN1PROD with PROPOSALS3
Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules 49243 

62301 (First Edition), and also to 

identify the most consistent and 

repeatable method for use in the DOE 

clothes washer test procedure. 

In the September 2010 NOPR, DOE 

proposed to require measurement of 

standby mode and off mode power 

using section 5, paragraph 5.3 of IEC 

Standard 62301 (First Edition), clarified 

by requiring the product to stabilize for 

at least 30 minutes and using an energy 

use measurement period of not less than 

10 minutes for cycle finished mode, 

inactive mode, and off mode. 75 FR 

57556, 57562–63 (Sept. 21, 2010). For 

delay start mode, the September 2010 

NOPR proposed to require the delay 

start time to be set to 5 hours, allowing 

at least a 5-minute stabilization period 

followed by a 60-minute measurement 

period. Id. at p. 57563. Further, for any 

clothes washer in which the power 

varies over a cycle, as described in 

section 5, paragraph 5.3.2 of the First 

Edition, the September 2010 NOPR 

proposed to require the use of the 

average power approach in section 5, 

paragraph 5.3.2(a). Id. 

For today’s supplemental notice, DOE 

compared the provisions of each edition 

under different scenarios of power 

consumption stability to determine the 

potential impacts of referencing the 

methodology from IEC Standard 62301 

(Second Edition) rather than from the 

First Edition. Based on this analysis, 

DOE is proposing in today’s SNOPR that 

the power measurement be made using 

a sampling method described in IEC 

Standard 62301 (Second Edition). 

Because, for the reasons discussed in 

section III.B.2, DOE is not proposing to 

require separate measurement of power 

consumption in cycle finished mode 

and delay start mode, the analysis 

presented in the following sections is 

limited to measurements made in 

inactive mode and off mode. 

a. Stable Power Consumption 

According to section 5, paragraph 

5.3.1 of IEC Standard 62301 (First 

Edition), power consumption is defined 

as stable if it varies by less than 5 

percent over 5 minutes. In such a case, 

a direct reading may be made at the end 

of the measurement period. With the 

proposed clarifications in the September 

2010 NOPR, the total test time for 

inactive mode or off mode would be a 

minimum of 40 minutes (comprised of 

a minimum 30-minute stabilization 

period, followed by a minimum 10- 

minute period during which the 

stability criterion could be evaluated 

and a direct power reading taken). 

Alternatively, the tester may select an 

average power or accumulated energy 

approach, again with a minimum 30- 

minute stabilization period and a 

minimum 10-minute measurement 

period. The average power approach 

would simply require a different reading 

to be taken from the instrument (true 

average power instead of a direct 

reading of instantaneous power), while 

the accumulated energy approach 

would require the calculation of power 

by dividing accumulated energy by the 

duration of the measurement period. 

In comparison, section 5, paragraph 

5.3.2 of IEC Standard 62301 (Second 

Edition) identifies a sampling method as 

the preferred means for all power 

consumption measurements and the 

fastest test method when the power is 

stable. For any non-cyclic power 

consumption, power readings are 

initially recorded over a period of at 

least 15 minutes after energizing the 

product. Data from the first third of the 

measurement period are discarded, and 

stability is evaluated by a linear 

regression through all power readings in 

the second two-thirds of the data. If the 

slope of the linear regression is less than 

10 milliwatts per hour (mW/h) for input 

power less than or equal to 1.0 W, or 

less than 1 percent of the input power 

per hour for input power greater than 

1.0 W, the power consumption is 

calculated as the average of the power 

readings during the second two-thirds of 

the measurement period. If the slope of 

the linear regression does not meet these 

stability criteria, the total period is 

continuously extended until the 

stability criteria are met for the second 

two-thirds of the data. In some cases, 

this is a more stringent requirement 

than the stability criteria of IEC 

Standard 62301 (First Edition). The lack 

of a definitive test period means that the 

test duration could extend past 15 

minutes for certain products—up to 3 

hours is allowed in the Second 

Edition—and could introduce added 

test burden as compared to the First 

Edition. In addition, performing the 

continuous linear regression analysis 

required by the Second Edition would 

require the use of data-acquisition 

software with the capability of 

performing real-time statistical analysis, 

whereas the First Edition requires only 

simple data logging capabilities. DOE 

requests comment on the potential test 

burden for a laboratory that would be 

required to upgrade its data acquisition 

system to enable real-time statistical 

analysis capabilities. 

IEC Standard 62301 (Second Edition) 

additionally provides an alternative 

measurement method which may be 

used when the power consumption is 

stable. Section 5, paragraph 5.3.4 of IEC 

Standard 62301 (Second Edition) 

specifies a direct reading method in 

which a minimum 30-minute 

stabilization period must be observed, 

followed by a first power measurement. 

After an additional period of 10 

minutes, a second power measurement 

is taken. If the average of the two 

measurements divided by the time 

interval between them meets certain 

threshold criteria, then the power 

consumption is considered to be the 

average of the two power measurements. 

Thus, the total test period would still be 

a minimum of 40 minutes. DOE agrees 

that this method likely improves the 

validity of the test results as compared 

to the First Edition, since it is a more 

stringent measure of the stability of the 

power consumption over a longer 

period of time than the First Edition 

requires. However, if the threshold 

criteria are not met at the end of the test, 

a different measurement method must 

be used. Further, the Second Edition 

specifies that the direct reading method 

shall not be used for verification 

purposes. Both of these qualifications 

potentially increase test burden as 

compared to the First Edition, possibly 

requiring the tester to conduct the more 

complex methodology of the methods 

available under the Second Edition. 

b. Unstable, Non-Cyclic Power 

Consumption 

Section 5, paragraph 5.3.2 from IEC 

Standard 62301 (First Edition), which 

DOE proposed in the September 2010 

NOPR to incorporate by reference with 

clarification, specifies that either the 

average power method or accumulated 

energy approach could be used for 

measuring unstable, non-cyclic power 

consumption (described in the Second 

Edition as non-cyclic and ‘‘varying’’ 

power consumption). As described 

previously, the clarifications proposed 

in the September 2010 NOPR would 

limit total test duration to 40 minutes 

for inactive mode and off mode. 

In contrast, paragraph 5.3 of the 

Second Edition requires the use of 

either a sampling method or average 

reading method for measuring unstable, 

non-cyclic power consumption in 

standby mode or off mode. As noted 

previously, DOE is proposing to require 

the use of the sampling method, based 

on the following analysis. 

The sampling method in paragraph 

5.3.2 is the same as described 

previously, but the measurement period 

must be at least 60 minutes, and the 

cumulative average of all data points 

recorded during the second two-thirds 

of the total period must fall within a 

band of ± 0.2 percent. The test 

procedure does not provide an upper 

time limit for testing, possibly resulting 

in significantly increased measurement

6 Delay start and cycle finished modes are 

considered part of the active mode. 

time if the cumulative average criteria 

cannot be achieved after 60 minutes. 

The average reading method in 

section 5, paragraph 5.3.3 in IEC 

Standard 62301 (Second Edition) 

describes both an average power method 

and accumulated energy method, either 

of which may be selected for unstable, 

non-cyclic power. For both types of the 

average reading method, a 30-minute 

stabilization period is specified, 

followed by two comparison 

measurement periods of not less than 10 

minutes each. The average power 

values, which are either measured 

directly or calculated from accumulated 

energy during each period, are 

compared to determine whether they 

agree to within certain threshold 

criteria. If the threshold is not achieved, 

the comparison periods are each 

extended in approximately equal 

increments until the threshold is met. If 

agreement is not achieved after reaching 

30 minutes for each comparison period, 

the sampling method must then be used. 

Therefore, the minimum test period is 

50 minutes, but may extend up to 90 

minutes, at which time an additional 

test may be required. 

DOE believes that the stability criteria 

in either method improves the accuracy 

and representativeness of the 

measurement as compared to the First 

Edition, but would cause the required 

test time to increase, with a 

corresponding increase in manufacturer 

burden due to the additional time and 

complexity of the test conduct. 

Additionally, DOE believes that 

manufacturers could face the risk of 

significant additional test burden if the 

average reading method is initially 

chosen but the power measurements do 

not meet the threshold criteria with the 

allowable 90-minute maximum test 

time, requiring a subsequent test using 

the sampling method. 

c. Cyclic Power Consumption 

As noted previously, DOE proposed 

in the September 2010 NOPR to use the 

average power approach of section 5, 

paragraph 5.3.2(a) in IEC Standard 

62301 (First Edition), with a minimum 

30-minute stabilization period and 10- 

minute measurement period. The First 

Edition also requires that at least one or 

more complete cycles be measured. 

In the Second Edition, cyclic power 

must be measured according to the 

sampling method in section 5, 

paragraph 5.3.2, but this method 

requires a measurement period of at 

least four complete cycles (for a total of 

at least 40 minutes) divided into two 

comparison periods, with stability 

criteria evaluated by calculating the 

difference in average power measured in 

each comparison period divided by the 

time difference of the mid-point of each 

comparison period. This ‘‘slope’’ must 

be less than 10 mW/h for input powers 

less than or equal to 1 W, and less than 

1 percent of the input power per hour 

for input powers greater than 1 W. If the 

appropriate stability criterion is not met, 

additional cycles are added to each 

comparison period until the criterion is 

achieved. Once stability has been 

reached, the power consumption is 

calculated as the average of all readings 

from both comparison periods. DOE 

believes that this methodology produces 

an improved measurement over the 

methodology from the First Edition, but 

the test duration could be extended, 

again potentially introducing issues of 

test burden. 

Conclusions on Incorporation of IEC 

Standard 62301 (Second Edition) 

In evaluating IEC Standard 62301 

(Second Edition) and comparing it to 

the First Edition, DOE recognizes the 

considerable body of comments on and 

input to the provisions and 

methodology that IEC developed as part 

of its latest revision process. DOE 

recognizes that, in some cases, test 

burden and complexity would be 

increased by requiring the use of the 

power supply, power measuring 

equipment, and test methods specified 

in the Second Edition. However, DOE 

believes that in most cases for 

residential clothes washers this added 

burden on manufacturers is outweighed 

by the improved accuracy and 

representativeness of the resulting 

power consumption measurement. 

Furthermore, manufacturers supported 

DOE’s use of the Second Edition. 

Therefore, DOE concludes provisionally 

that the application of the provisions of 

the Second Edition to all power 

measurements in standby mode and off 

mode for clothes washers would be an 

improvement over the First Edition and 

would not be unduly burdensome to 

conduct. Therefore, DOE is proposing 

incorporation by reference of the 

relevant paragraphs of section 4 and 

section 5 of IEC Standard 62301 (Second 

Edition) in the clothes washer test 

procedure. 

To this end, DOE is also proposing to 

amend the reference in 10 CFR 430.3 to 

add a reference to IEC Standard 62301 

(Second Edition). DOE is not proposing 

to replace the reference to the First 

Edition in 10 CFR 430.3 because several 

test procedures for other covered 

products not addressed in today’s 

SNOPR incorporate provisions from it. 

There are also certain section 

numbering differences between the First 

Edition and Second Edition of IEC 

Standard 62301 that impact the text of 

the measurement provisions proposed 

for the clothes washer test procedure in 

appendix J2. DOE further notes that the 

mode definitions that were proposed in 

the September 2010 NOPR would not be 

affected by the reference to IEC 

Standard 62301 (Second Edition) 

because the definitions were based on 

IEC Standard 62301 (FDIS), which is 

identical in substance to the Second 

Edition. 

Further, DOE observes that although 

the Second Edition allows the choice of 

multiple test methods for both stable 

and unstable non-cyclic power 

consumption, the sampling method 

provides for a test duration that is 

approximately the same or shorter than 

the allowable alternative methods and 

does not require classification of the 

nature of the power consumption (e.g., 

stable or unstable, non-cyclic) in 

advance of the test. The average reading 

method in the Second Edition allows 

the use of either the average power 

method or accumulated energy method, 

at the discretion of the test laboratory, 

which could result in inconsistent test 

results among different test laboratories. 

Furthermore, for cyclic power 

consumption, the Second Edition 

requires the use of the sampling 

method. For these reasons, DOE 

proposes in today’s SNOPR to specify 

the use of the sampling method in IEC 

Standard 62301 (Second Edition) 

section 5.3.2 for all measures of standby 

mode and off mode power consumption. 

2. Calculation of Energy Use in LowPower Modes 

In the September 2010 NOPR, DOE 

proposed two possible approaches for 

measuring energy consumption in 

modes other than active washing mode; 

i.e., inactive (standby) mode, off mode, 

delay start mode, and cycle finished 

mode 6 (hereafter, collectively referred 

to as low-power modes). 

For the first approach, DOE proposed 

allocating 295 hours per year to the 

active washing mode, 16 hours to selfclean mode (if applicable), 25 hours per 

year to delay start mode (if applicable), 

15 hours per year to cycle finished 

mode (if applicable), and the remainder 

to off and/or inactive mode. 75 FR 

57556, 57564–65 (Sept. 21, 2010). Using 

this approach, the energy use per cycle 

associated with inactive, off, delay start, 

and cycle finished modes would be 

calculated by (1) Calculating the 

product of wattage and allocated hours 

for all possible inactive, off, delay start 

and cycle finished modes; (2) summing 


jlentini on DSK4TPTVN1PROD with PROPOSALS3
Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules 49245 

the results; (3) dividing the sum by 

1,000 to convert from Wh to kWh; and 

(4) dividing by the proposed 295 use 

cycles per year. 

For the second ‘‘alternate approach,’’ 

DOE proposed measuring power 

consumption for only off and inactive 

modes for the purpose of calculating the 

total energy consumed in all low-power 

modes. Using this approach, separate 

measurements of delay start and cycle 

finished mode energy consumption 

would not be required; instead, all the 

hours not associated with active 

washing mode or self-clean mode (8,465 

hours total) would be allocated to the 

inactive and off modes. DOE noted that 

delay start and cycle finished modes 

represent a relatively small number of 

hours at low power consumption levels. 

For clothes washers currently on the 

market, these levels are comparable to 

those for off/inactive modes. Id. 

In evaluating the best approach for 

measuring energy use in low-power 

modes, DOE considered comments from 

interested parties regarding the 

allocation of hours to modes other than 

active washing mode. A number of these 

comments related to the estimates DOE 

provided of the number of hours 

associated with each low-power mode. 

NEEA objected to DOE’s proposed 

allocation of the time spent in cycle 

finished mode, based on an estimate of 

3 minutes per cycle. NEEA stated that 

DOE relied on anecdotal data from 

Australia to determine its estimates. 

NEEA also noted that DOE was aware of 

units capable of operating up to 10 

hours in cycle finished mode, but had 

no field data to support an assumption 

about what fraction of the 10 hours were 

used, nor any data that would allow an 

estimate of the typical cycle finished 

mode duration. NEEA recommended 

that DOE acquire data to provide a 

statistically valid basis for assumptions 

about the duration of cycle finished 

mode. NEEA further commented that 

there is no reason to exclude the 

measurement of the energy use of fans 

and motors in the cycle finished mode, 

or to arbitrarily curtail the time period 

for their measurement. (NEEA, No. 12 at 

pp. 3, 7; NEEA, Public Meeting 

Transcript, No. 20 at pp. 75–76) 

NEEA also commented that recent 

field measurements conducted for the 

California Public Utility Commission 

(CPUC) indicate that inactive mode 

energy use can be significant, equivalent 

to the energy consumption of an 

additional wash load per week (not 

including hot water energy 

consumption). (NEEA, No. 12 at p. 3) 

NEEA stated that DOE’s estimates for 

the time spent in the inactive mode call 

into question the need for the specified 

accuracy in measuring the power use in 

the inactive mode. (NEEA, No. 12 at p. 

7) 

The California Utilities commented 

that DOE should increase the length of 

time allocated to cycle finished mode in 

the test procedure calculations. The 

California Utilities further noted that the 

Australian study on which DOE relied 

for other estimates in the proposed test 

procedure showed that 20 percent of the 

total use time not allocated to active 

washing or delay start mode would be 

associated with the cycle finished mode. 

Additionally, the California Utilities 

noted that DOE’s estimates were based 

on internal testing, although it is not 

clear if the proposed cycle finished 

mode duration was based on all 

machines tested, or only those having a 

cycle finished mode, and requested 

either a clarification or correction to this 

calculation. The California Utilities 

stated that it also was not clear whether 

DOE’s test sample included machines 

providing periodic air flow or tumbling 

in the cycle finished mode, or if it only 

tested machines with an extended 

display operation. The California 

Utilities recommended that DOE test 

machines with these additional features 

to determine their typical cycle finished 

mode duration, which for some 

machines may be hours after completion 

of the wash cycle. (California Utilities, 

No. 18 at pp. 2–3) 

ALS did not agree that cycle finished 

mode energy consumption should be 

accounted for separately from the active 

washing mode. (ALS, No. 10 at p. 1) 

Whirlpool commented that DOE should 

not measure or include in the test 

procedure cycle finished energy 

consumed by air movement fans or by 

periodic tumbling, as these are very 

limited application features where the 

measurement burden would 

substantially outweigh the value of the 

energy measurement. (Whirlpool, No. 13 

at p. 2) Whirlpool commented further 

that the significant test burden 

associated with measuring cycle 

finished mode results in virtually no 

consumer benefit, and these values 

should be dropped from the test 

procedure’s calculations. (Whirlpool, 

No. 13 at p. 4) 

AHAM also commented in response 

to the RFI issued by DOE to implement 

Executive Order 13563, ‘‘Improving 

Regulation and Regulatory Review, 

opposing any test procedure 

requirement to measure separately the 

energy use of delay start and cycle 

finished modes. AHAM stated that the 

additional burden that would be 

required to measure a de minimis 

amount of energy would not be justified. 

(76 FR 6123, Feb. 3, 2011; AHAM, 5–6) 

DOE also received multiple comments 

from interested parties regarding the 

proposed ‘‘alternate approach,’’ which 

would allocate all the hours not 

associated with active washing mode to 

the inactive and off modes. 

ALS, AHAM, and BSH support the 

alternative calculation proposed in the 

September 2010 NOPR. (ALS, No. 10 at 

p. 2; AHAM, No. 14 at p. 8; AHAM, 

Public Meeting Transcript, No. 20 at pp. 

87–88; BSH, No. 17 at p. 3) ALS and 

AHAM generally oppose the proposed 

method of separately allocating annual 

hours to delay start mode, cycle finished 

mode, and self-clean mode because they 

believe that DOE does not have reliable 

consumer use data for these modes. In 

addition, as stated above, ALS and 

AHAM stated that these modes 

represent insignificant energy 

consumption to justify measuring them 

separately. (ALS, No. 10 at p. 2; AHAM, 

No. 14 at p. 7; AHAM, Public Meeting 

Transcript, No. 20 at pp. 55–56, 73, 93) 

Whirlpool also commented that the test 

procedure should not include delay 

start mode, cycle finished mode, or off 

mode because these modes represent 

insignificant energy consumption. 

(Whirlpool, No. 13 at p. 4). 

NEEA opposed the proposed 

alternative calculation method, stating 

that it would be inappropriate to ignore 

the delay start and cycle finished modes 

with almost no data on the actual 

duration and energy use for these 

modes. (NEEA, No. 12 at p. 8) NEEA 

believes that the energy use in delay 

start mode and cycle finished mode is 

not insignificant, and should be 

included in the energy use calculations. 

According to NEEA, manufacturers 

would have no incentive to minimize 

energy used in these modes if they were 

not included in the calculations. (NEEA, 

No. 12 at p. 8) NEEA further commented 

that the proposed calculation method 

for measuring each mode is sound, but 

could be simplified if the calculation 

simply involved active mode, with 

delay start mode and cycle finished 

mode folded in, and inactive mode, as 

measured for each model tested. (NEEA, 

No. 12 at p. 7) NEEA did, however, 

comment that it might support the 

alternative approach if the active wash 

mode is defined for each machine to 

include any cycle finished mode, 

including machines with cycle finished 

modes with intermittent tumbling that 

can last as long as 10 hours. (NEEA, 

Public Meeting Transcript, No. 20 at p. 

88) 

The Appliance Standards Awareness 

Project (ASAP), American Council for 

an Energy-Efficient Economy (ACEEE), 

and NRDC (hereafter referred to as the 

‘‘Joint Comment’’) expressed support for 


jlentini on DSK4TPTVN1PROD with PROPOSALS3
49246 Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules 

NEEA’s proposal to fold delay start and 

cycle finished modes into a single 

energy test cycle that would also 

include the active wash cycle. The Joint 

Comment stated that this approach 

would seem to simplify the test, and it 

would ensure that any energy and/or 

water consumption that occurs after the 

final spin, such as the addition of steam, 

would be captured by the test 

procedure. (Joint Comment, No. 16 at p. 

4) 

DOE acknowledges that certain 

clothes washers provide optional 

tumbling or air circulation features in 

cycle finished mode. As noted in the 

September 2010 NOPR, the number of 

residential clothes washers equipped 

with a periodic tumbling or air 

circulation feature during cycle finished 

mode represents less than 10 percent of 

the models produced by manufacturers 

comprising over 90 percent of the 

market. 75 FR 57556, 57561 (Sept. 21, 

2010). In addition, review of product 

literature for the clothes washers 

equipped with such features shows that 

these functions are typically consumerselected options. 

To further support the proposal in 

today’s SNOPR, DOE performed 

additional laboratory testing to quantify 

the energy consumption in cycle 

finished mode. DOE tested the 

residential clothes washer model that it 

identified as having the longest-duration 

and most energy-intensive cycle 

finished feature on the market. This 

clothes washer includes a userselectable option that provides periodic 

tumbling and air circulation for up to 10 

hours following the completion of the 

wash cycle. For the duration of this 

cycle finished mode, the cycle finished 

indicator on the control panel remains 

activated, the door remains locked, and 

an additional feature indicator light on 

the control panel flashes. 

DOE measured the energy 

consumption of this cycle finished 

feature for the maximum possible 10 

hour duration, using the warm wash/ 

cold rinse energy test cycle and the 

average test load size as indicated by 

Table 5.1 in appendix J1, extended 

linearly as discussed in section III.B.7.a. 

These test parameters were chosen 

because they correspond to the highest 

usage factors according to the appendix 

J1 test procedure. DOE also measured 

the clothes washer’s standby energy 

consumption. Figure III.1 shows the 

power consumption in W during the 

active washing mode followed by the 

first 45 minutes of cycle-finished mode. 

The shaded portion of the figure 

indicates cycle finished mode. 

Table III.2 shows the cycle finished 

mode energy consumption for the test 

clothes washer along with the other 

factors that the proposed Integrated 

Modified Energy Factor (IMEF) metric 

incorporates: (1) Machine electrical 

energy use in active washing mode, (2) 

hot water energy use in active washing 

mode, (3) energy associated with 

moisture removal (i.e., drying energy), 

and (4) standby (inactive) mode energy 

use.

Figure III.2 shows the relative 

magnitude of each of the contributors to 

total per-cycle energy consumption for 

both scenarios. 

The cycle finished feature of this 

clothes washer consumes 0.08 kWh over 

the maximum 10-hour duration. After 

accounting for the 10 fewer hours in 

inactive mode, the cycle finished feature 

with intermittent tumbling and air 

circulation would add a net 0.06 kWh 

to the total per-cycle energy 

consumption of this clothes washer, an 

increase of 3.0 percent. If consumers 

were to select this feature for all wash 

cycles, IMEF would decrease by 3.0 

percent. 

DOE recognizes that the 3.0 percent 

decrease in IMEF represents a worstcase scenario. A 3-percent increase in 

annual energy consumption would 

occur only if a consumer activated this 

feature on 100 percent of laundry cycles 

and if the cycle-finished activity 

persisted for the full 10 hours after 

every cycle. While DOE lacks consumer 

usage data of this cycle finished feature, 

DOE believes it is reasonable that 

consumers would activate this feature 

less than 100 percent of the time, and 

that, on average, the cycle finished 

activity would persist for less than the 

full 10 hours. For illustrative purposes, 

if a consumer selected the cycle finished 

option on 50 percent of all wash cycles, 

and, on average, the cycle finished 

activity persisted for 50 percent of the 

maximum allowable time (i.e., for 5 

hours), total annual energy consumption 

would increase by only 0.75 percent. 

Based on the results of the data 

presented here, DOE believes that 

including a specific measurement of 

energy use of a cycle finished feature 

that incorporates intermittent tumbling 

and air circulation would not 

significantly impact the total annual 

energy consumption. Furthermore, 

measuring the energy use over the entire 

duration of cycle finished mode would 

increase the test duration by up to 10 

hours, depending on the maximum 

duration of cycle finished mode 

provided on the clothes washer under 

test. DOE believes this would represent 

a significant increase in test burden that 

would not be warranted by the minimal 

additional energy use captured by 

measuring cycle finished mode 

separately or as part of the active 

washing mode. 

Therefore, in consideration of the data 

and estimates previously presented in 

the September 2010 NOPR, the 


jlentini on DSK4TPTVN1PROD with PROPOSALS3EP09AU11.015</GPH>
49248 Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules 

additional energy consumption 

estimates presented in this SNOPR, the 

uncertainty regarding consumer usage 

patterns, and the additional test burden 

required, DOE is not proposing to adopt 

provisions to measure cycle finished 

mode separately or as part of the active 

washing mode. In the absence of a 

compelling reason to treat cycle finished 

mode separately, DOE believes that its 

assumption set forth in the September 

2010 NOPR that the power consumption 

in each low-power mode is similar 

remains valid, and that in such a case, 

measuring power consumption of each 

mode separately would introduce 

significant test burden without a 

corresponding improvement in a 

representative measure of annual energy 

use. Therefore, DOE is proposing in 

today’s SNOPR to adopt the ‘‘alternate 

approach’’ for measuring total energy 

consumption, in which all low-power 

mode hours are allocated to the inactive 

and off modes, and the low-power mode 

power consumption is measured only in 

the inactive and off modes, depending 

on which of these modes is present. 

3. Energy Test Cycle Definition 

The energy test cycle is the cycle 

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 

based on (A) The cycle recommended 

by the manufacturer for washing cotton 

or linen clothes, which includes all 

wash/rinse temperature selections and 

water levels offered in that cycle; and 

(B) other cycles that may include other 

temperature or water level options if 

they contribute to an accurate 

representation of energy consumption. 

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 options available only on 

cycle settings other than that defined in 

part (A) of the definition. 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). 

In testing conducted since the 

September 2010 NOPR, DOE has 

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 proposes in 

today’s 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’’ cycle, the 

manufacturer would use the whites 

cycle to test that temperature setting. 

Because the default temperature setting 

for the whites cycle may be warm or 

hot, however, the manufacturer would 

have to manually adjust the temperature 

to get to extra hot. For certification 

testing in such cases, the manufacturer 

would use the default settings on the 

whites cycle for all options except the 

temperature setting, which would be 

manually adjusted to achieve the 

desired temperature. 

In addition, DOE proposes to delete 

‘‘and required for testing as described in 

this test procedure’’ from part (B) as 

redundant and unnecessary. 

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 

serious consequences in variations in 

testing across laboratories or 

technicians. (AHAM, No. 14 at p. 15) 

DOE believes that the proposed 

modification to part (B) provides 

additional specificity on the wash cycle 

settings (i.e., agitation/tumble operation, 

spin speed(s), wash times, and rinse 

times) that, if comparable to those for 

the cycle recommended by the 

manufacturer for washing cotton or 

linen clothes, must be considered under 

part (B) of the energy test cycle 

definition. 

4. Load Adjustment Factor 

The clothes washer test procedure 

relies on use factors to weight different 

consumer behaviors in the overall 

energy and water consumption 

calculations. The factors are based on 

consumer use data and represent the 

fraction of all cycles that are run with 

certain settings or characteristics. The 

Load Adjustment Factor (LAF) 

represents the ratio of maximum load 

size to average load size. This ratio is 

used in the calculation of the energy 

required to remove moisture from the 

test load (i.e., drying energy). The RMC 

value used in this calculation is based 

only on tests using the maximum test 

load—the LAF is used to scale this 

value down to the average load size. In 

the September 2010 NOPR, DOE noted 

that it lacked information warranting 

adjusting this value or changing it from 

a fixed value to one that varies as a 

function of average load size, and 

therefore did not propose to amend the 

LAF in the test procedure. 75 FR 57556, 

57572 (Sept. 21, 2010). 

AHAM and ALS support DOE’s 

proposal to retain the existing LAF in 

the test procedure. (AHAM, No. 14 at 

p. 13; ALS, No. 10 at p. 4) BSH, The 

California Utilities, Energy Solutions 

(ES), NEEA, Natural Resources Defense 

Council (NRDC), and the Joint Comment 

stated that it is an inconsistency in the 

test procedure to have a single LAF that 

does not correlate with the load usage 

factors. (BSH, Public Meeting 

Transcript, No. 20 at pp. 149–150; 

California Utilities, No. 18 at p. 4; ES, 

Public Meeting Transcript, No. 20 at 

p. 150; Joint Comment, No. 16 at pp. 5– 

6; NEEA, Public Meeting Transcript, No. 

20 at p. 149) ASAP commented that an 

average load size value that depends on 

capacity does not represent consumer 

usage. (ASAP, Public Meeting 

Transcript, No. 20 at pp. 151–152) ES 

stated that the ratio of average load size 

to maximum load size is 70–75 percent 

for small clothes washers but is closer 

to 50–55 percent for larger clothes 

washers. (ES, Public Meeting Transcript, 

No. 20 at p. 150) The California Utilities 

recommended that RMC be measured by 

testing with minimum, average, and 

maximum test load sizes, with the 

average test load size calculated as 65 

percent of the maximum load size. The 

California Utilities further commented 

that the results from each test load size 

should be weighted using the same load 

usage factors as those used for the 

energy test cycle. (California Utilities, 

No. 18 at p. 4) NRDC stated that a single 

LAF could be calculated from the three 

weighting values assigned to the load 

usage factors. (NRDC, Public Meeting 

Transcript, No. 20 at pp. 142–145, 148– 

149) NEEA and the Joint Comment 

doubted that the relationship between 


jlentini on DSK4TPTVN1PROD with PROPOSALS3
Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules 49249 

tested RMC values and load size is 

linear for most clothes washers. 

According to the Joint Comment, the 

Bern Clothes Washer Study found that 

RMC decreases with increasing load size 

and that this effect is more significant 

for top-loaders than for front-loaders. 

Due to this finding, the Joint Comment 

believes that measuring RMC at a 

maximum load size and assuming that 

the same RMC would apply to an 

‘‘average’’ load size likely 

underestimates actual RMC and 

therefore dryer energy consumption for 

an ‘‘average’’ load size. Instead, the Joint 

Comment suggested that RMC be 

measured for minimum, maximum, and 

average load sizes and that dryer energy 

consumption be calculated for each load 

size using the corresponding measured 

RMC. A weighted-average dryer energy 

consumption could then be calculated 

using the load usage factors. The Joint 

Comment stated that, although this 

approach would slightly increase test 

burden, it believes the increased burden 

would be insignificant because tests 

with the different load sizes are already 

required to be run in the current test 

procedure. Therefore, the Joint 

Comment stated that the only addition 

would be an RMC measurement for each 

of the different load size test cycles 

rather than just for the maximum load 

test cycle. (Joint Comment, No. 16 at 

pp. 7–8) NEEA also noted that there is 

no average test load size for manual fill 

models, but three different load sizes for 

adaptive fill models. According to 

NEEA, a weighted-average value for 

LAF is more appropriate, but even better 

would be to conduct RMC tests at 

various load sizes, and use the load 

usage factors to obtain weighted-average 

results. (NEEA, No. 12 at pp. 12–13) 

DOE notes that both the LAF and load 

usage factors are intended to adjust test 

results measured at discrete load sizes 

to values that are representative of realworld consumer use. The LAF, 

however, is also intended to capture the 

dependence of RMC on load size 

because the RMC test is conducted 

using only the maximum load size. 

As observed by the California 

Utilities, data collected as part of the 

Bern Clothes Washer Study suggest that 

an RMC test conducted at maximum 

load size would produce a different 

RMC than a test conducted at the 

average load size. Because the LAF must 

account for two effects—the percentage 

of times that users select different load 

sizes and the variation of measured 

RMC with load size—it would be 

expected to differ somewhat from any of 

the load usage factors, which capture 

only the consumer load size selection 

effect. For the August 1997 Final Rule, 

however, DOE obtained information 

that, when averaged with data provided 

by interested parties, showed that the 

relationship between load size and RMC 

was almost non-existent. For this 

reason, DOE concluded in the August 

1997 Final Rule that it was acceptable 

to test RMC using only the maximum 

load size. DOE does not believe that 

conducting multiple RMC 

measurements at different load sizes 

would improve the calculation of drying 

energy use. Additionally, DOE believes 

that the Bern Study is inconclusive with 

respect to the LAF because (1) The 

relationship between RMC and load size 

was not demonstrated for individual 

machines, and (2) the test load 

composition was not controlled. 

In light of the available data 

suggesting that load size does not affect 

the RMC measurement, the remaining 

trend that the LAF is intended to 

capture is the pattern of consumer 

selection of load size, which is already 

incorporated in the test procedure via 

the load usage factors. This suggests that 

the LAF is duplicative of, yet 

inconsistent with, the load usage 

factors. Therefore, DOE proposes in 

today’s SNOPR that, for consistency 

with the rest of the test procedure, the 

representative load size calculation in 

the equation for drying energy should 

incorporate the load usage factors rather 

than a separate LAF. In the current 

drying energy calculation, the 

representative load size is calculated by 

multiplying the fixed value of LAF by 

the maximum load size. DOE proposes 

that this representative load size be 

replaced by a weighted-average load 

size calculated by multiplying the 

minimum, average, and maximum load 

usage factors by the minimum, average, 

and maximum load sizes, respectively, 

and summing the products. 

5. Wash Time Setting 

The current test procedure specifies 

the wash time setting to be used in the 

energy test cycle. If only one wash time 

is prescribed in the energy test cycle, 

that wash setting is to be used; 

otherwise, the wash time setting is 

required to be the higher of either the 

minimum wash time or 70 percent of 

the maximum wash time available in 

the energy test cycle. DOE has recently 

become aware that, for certain clothes 

washers equipped with an 

electromechanical dial to control wash 

time, the dial may yield different results 

for the same setting depending on the 

direction in which the dial is turned to 

reach the desired setting. DOE believes 

that consistency in setting the wash 

time in such cases may be achieved by 

resetting the dial to the minimum wash 

time and then turning it in the direction 

of increasing wash time to reach the 

desired setting. If the desired setting is 

passed, the dial should not be turned in 

the direction of decreasing wash time to 

reach the setting. Instead, the dial 

should be returned to the minimum 

wash time and then turned in the 

direction of increasing wash time until 

the desired setting is reached. DOE, 

therefore, proposes to add these 

clarifications to the wash time setting 

provisions in both appendix J1 and 

appendix J2. DOE believes that this 

clarification would not affect the energy 

and water use measurements, but would 

help ensure consistency when 

determining compliance with energy 

conservation standards. To provide 

further consistency, DOE also proposes 

the further clarification that the 

conditions stated in the case of more 

than one wash time setting—that 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—shall apply 

regardless of the labeling of suggested 

dial locations. 

6. Annual Energy Cost 

In the September 2010 NOPR, DOE 

considered whether to amend the 

estimated annual operating cost 

calculation in 10 CFR 430.23 to include 

the cost of energy consumed in the nonactive washing modes, but did not 

propose such amendments for the 

following reasons: 

• DOE believed that the cost of energy 

consumed in self-clean, standby, off, 

delay start, and cycle finished modes is 

small relative to the total annual energy 

cost for clothes washers, and therefore, 

would make little difference in the 

estimated annual operating cost 

calculation. 

• The Federal Trade Commission’s 

(FTC’s) EnergyGuide Label for clothes 

washers uses the estimated annual 

operating cost as its primary indicator of 

product energy efficiency, compared to 

a range of annual operating costs of 

similar products. Appendix F1 to 

16 CFR part 305. An estimated annual 

operating cost incorporating self-clean, 

standby, off, delay start, and cycle 

finished mode energy use would no 

longer be directly comparable to the 

minimum and maximum energy costs 

prescribed for the EnergyGuide label. 

75 FR 57556, 57567 (Sept. 21, 2010). 

ALS and AHAM supported DOE’s 

proposal to maintain the existing energy 

cost calculation. (ALS, No. 10 at p. 3; 

AHAM, No. 14 at p. 9) AHAM and 

Whirlpool commented, however, that 

DOE’s proposal to exclude non-active

49250 Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules 

washing modes from the annual energy 

cost calculation is inconsistent with the 

proposal to include these modes in the 

IMEF calculation. (Whirlpool, No. 13 at 

p.5; AHAM, No. 14 at p. 9). 

NEEA disagreed with DOE’s assertion 

that the cost of energy consumed in 

non-active washing modes would make 

little difference in the estimated annual 

operating cost calculation. NEEA noted 

that no publicly available data exists on 

which to base such an assertion, but that 

end-use data from the field suggests that 

standby energy could constitute as 

much as 5 to 10 percent of total clothes 

washer energy use, not including drying 

energy use. (NEEA, No. 12 at p. 8) 

EPCA requires that 180 days after the 

amended test procedure is prescribed, 

all representations related to the energy 

use, efficiency, or cost of energy 

consumed for residential clothes 

washers must reflect the results of 

testing according to the amended test 

procedure, which will include 

provisions for measuring standby and 

off mode energy use. (42 U.S.C. 

6293(c)(2)) Additionally, EPCA requires 

that any revisions to the labels for 

residential clothes washers include 

disclosure of the estimated annual 

operation cost (determined in 

accordance with DOE’s test procedures 

prescribed under section 6293 of EPCA), 

unless the Secretary determines that 

disclosure of annual operating cost is 

not technologically feasible, or if the 

FTC determines that such disclosure is 

not likely to assist consumers in making 

purchasing decisions or is not 

economically feasible. (42 U.S.C. 

6294(c)(1)) 

For these reasons, DOE agrees that the 

annual energy cost calculations in 

10 CFR 430.23 for residential clothes 

washers should be amended to include 

the cost of energy consumed in nonactive washing modes. Therefore, DOE 

proposes to amend the clothes washer 

test procedure to revise the estimated 

annual operating cost calculation to 

integrate energy use in standby, off and 

self-clean modes. The estimated annual 

operating cost would be obtained by 

multiplying the 295 average number of 

annual use cycles by: (1) When 

electrically heated water is used: (total 

per-cycle machine electrical energy 

consumption + per-cycle hot water 

energy consumption + per-cycle selfclean energy consumption + per-cycle 

‘‘combined low-power’’ mode energy 

consumption) × (the representative 

average unit cost in dollars per kWh, as 

provided by the Secretary); or (2) when 

gas-heated or oil-heated water is used: 

[(per-cycle machine electrical energy 

consumption + per-cycle self-clean 

machine electrical energy consumption 

+ per-cycle combined low-power mode 

energy consumption) × (the 

representative average unit cost in 

dollars per kWh, as provided by the 

Secretary)] + [(per-cycle water energy 

consumption for gas-heated or oilheated water + per-cycle self-clean 

water energy consumption for gasheated or oil-heated water) × 

(representative average unit cost in 

dollars per Btu for oil or gas, as 

appropriate, as provided by the 

Secretary)]. The estimated annual 

operating cost would be rounded off to 

the nearest dollar per year. To provide 

for the appropriate per-cycle electrical 

and water heating measures used in the 

annual energy cost calculation, DOE 

proposes new calculations of per-cycle 

self-clean electrical, hot water, and 

overall energy consumption in today’s 

SNOPR. 

7. Additional Proposals 

a. Extension of Test Load Size Table 

The clothes washer test procedure at 

appendix J1 specifies test load size for 

the active washing mode energy tests 

based on the clothes washer’s container 

volume. The table specifying the test 

load sizes, Table 5.1, currently covers 

clothes washer container volumes up to 

only 3.8 ft 3. DOE stated in the 

September 2010 NOPR that it was aware 

of multiple clothes washers available on 

the market that have clothes container 

volumes exceeding 3.8 ft,3 and proposed 

to revise Table 5.1 in the amended test 

procedure in appendix J2 to establish 

test load size specifications for clothes 

washer container volumes up to 6.0 ft 3. 

The proposed extension was based on a 

continuation of the linear relationship 

between test load size and clothes 

washer container volume in the DOE 

clothes washer test procedure at 

appendix J1. 75 FR 57556, 57570–71 

(Sept. 21, 2010). 

DOE also received petitions for waiver 

from the current clothes washer test 

procedure from a number of 

manufacturers for clothes washers that 

they produce with clothes container 

volumes greater than 3.8 ft 3. DOE 

granted waivers to these manufacturers, 

all of which contained alternate test 

procedures based on similar linear 

extensions of Table 5.1. 

DOE proposes to extend Table 5.1 in 

appendices J1 and J2 based on the 

extended version of Table 5.1 proposed 

in the September 2010 NOPR for 

appendix J2, with some minor 

adjustments. In the September 2010 

NOPR, DOE presented inconsistent 

decimal places in the minimum, 

average, and maximum load sizes in 

Table 5.1. This subsequently affected 

the calculation of some of the average 

load size values in the table. In today’s 

SNOPR, DOE proposes to amend the 

extension to Table 5.1 in appendices J1 

and J2 by specifying each load size 

value to the hundredths decimal place. 

b. Correction to Cold Rinse Definition 

After the publication of the September 

2010 NOPR, DOE became aware of an 

error in the definition of cold rinse in 

the test procedure at appendix J1. 

Specifically, cold rinse is defined in 

section 1.22 of appendix J1 as ‘‘the 

coldest rinse temperature available on 

the machine (and should be the same 

rinse temperature selection tested in 3.7 

of this appendix).’’ However, section 3.7 

of appendix J1 contains provisions for 

testing warm rinse, which instruct that 

such tests be conducted with the hottest 

rinse temperature available. Thus, 

section 3.7 is inapplicable to the 

definition of cold rinse in section 1.22. 

DOE proposes in today’s SNOPR to 

remove reference to section 3.7 in the 

definition of cold rinse in both section 

1.22 of appendix J1 and proposed 

section 1.7 of appendix J2. 

c. Deletion of Redundant Test Cloth 

Specifications 

In the September 2010 NOPR, DOE 

proposed deleting the redundant 

sections 2.6.1.1–2.6.1.2.4 from appendix 

J2. These sections pertain to test cloth 

specifications and preconditioning and 

were made obsolete in the 2001 Final 

Rule, which added sections 2.6.3 

through 2.6.7.2 into appendix J1. 66 FR 

3314. In today’s SNOPR, DOE proposes 

to remove these redundant sections 

from appendix J1 as well. Consistent 

with the proposal in the September 

2010 NOPR, DOE proposes to use in 

section 2.6.4.3 the thread count 

specification from deleted section 

2.6.1.1(A), of 65 × 57 per inch (warp × 

fill), based on supplier data. 

Additionally, DOE proposes to maintain 

a shrinkage limit, relocated from section 

2.6.1.1(B) to new section 2.6.4.7, but to 

increase the current 4 percent limit to 5 

percent. DOE also proposes to require 

the cloth shrinkage to be measured as 

per the American Association of Textile 

Chemists and Colorists (AATCC) Test 

Method 135–2010, ‘‘Dimensional 

Changes of Fabrics after Home 

Laundering.’’ These revisions are also 

supported by supplier data, according to 

AHAM. (AHAM, No. 15 at p. 15). 

d. Detergent Specifications for Test 

Cloth Preconditioning 

In the September 2010 NOPR, DOE 

proposed amending the clothes washer 

test procedure to specify the use of 

AHAM standard test detergent Formula 


jlentini on DSK4TPTVN1PROD with PROPOSALS3
Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules 49251 

3 in test cloth preconditioning, at a 

dosing of 27.0 g + 4.0 g/lb. DOE 

proposed incorporating this amendment 

into the proposed appendix J2 test 

procedure. 

ALS supported DOE’s proposal to 

specify the use of AHAM standard 

detergent Formula 3 in test cloth 

preconditioning as well as the proposal 

to follow the instructions included with 

the detergent, because it is makes the 

dosing common with the Dryer Test 

Load preconditioning procedure. (ALS, 

No. 10 at p. 5) NEEA stated that it 

foresees no problem with, and some 

benefit from, adopting the AHAM 

detergent specification. (NEEA, No. 12 

at p. 14) Whirlpool stated that the 

proposed detergent formulation and 

dosage changes are consistent with 

AHAM Standard HLD–1–2009, which 

Whirlpool supports. (Whirlpool, No. 13 

at p. 14) AHAM supported DOE’s 

proposal to amend the test procedure to 

specify the use of AHAM standard test 

detergent Formula 3 in test cloth 

preconditioning at a dosing of 27.0g 

+4.0g/lb (AHAM, No. 14 at p. 15; Public 

Meeting Transcript, No. 20 at pp. 194– 

195). 

In today’s SNOPR, DOE proposes to 

amend the appendix J1 and J2 test 

procedures to require the use of the 

current AHAM standard test detergent 

formula for test cloth preconditioning, 

at a dosing of 27.0g +4.0g/lb. The 

current AHAM standard test detergent is 

Formula 3. 

e. Cold Wash Temperature Selection 

DOE has observed multiple clothes 

washer models that offer a ‘‘tap cold’’ 

wash temperature setting in addition to 

a ‘‘cold’’ wash temperature setting. DOE 

proposes to clarify how to classify these 

temperature selections in appendix J1 

and appendix J2. 

Section 3.6 of appendix J1 defines the 

cold wash selection as ‘‘the coldest 

wash temperature selection available.’’ 

Additionally, section 1.18 of Appendix 

J1 defines ‘‘warm wash’’ as ‘‘all wash 

temperature selections below the hottest 

hot, less than 135 °F, and above the 

coldest cold temperature selection.’’ In 

some cases with these models, DOE has 

observed that the ‘‘cold’’ setting mixes 

in hot water to raise the temperature 

above the cold water supply 

temperature, as defined in section 2.3 of 

Appendix J1. In such cases, DOE 

proposes that the manufacturer 

specified ‘‘cold’’ setting should be 

considered a warm wash, as defined in 

section 1.18; and that the ‘‘tap cold’’ 

setting should be considered the cold 

wash, as defined in section 3.6. In cases 

where the ‘‘cold’’ setting does not add 

any hot water for any of the test loads 

required for the energy test cycle, the 

‘‘cold’’ setting should be considered the 

cold wash; and the ‘‘tap cold’’ setting 

would not be required for testing. DOE 

requests comment on the 

appropriateness of this clarification. 

f. Correction to Per-Cycle Self-Clean 

Water Consumption Calculation 

In the September 2010 NOPR, DOE 

proposed incorporating per-cycle selfclean hot water energy consumption 

(section 4.1.8) into the calculation for 

IMEF, as well as total per-cycle selfclean water consumption (section 

4.2.14) into the calculation for IWF in 

appendix J2. The proposed calculations 

in section 4.1.8 and section 4.2.14 did 

not contain the numeric multipliers 

required to apportion the total annual 

self-clean water consumption over the 

295 representative average number of 

clothes washer cycles in a year. In 

today’s SNOPR, DOE proposes to adjust 

the calculations in section 4.1.8 and 

4.2.14 by including a multiplier of 

12/295, where 12 represents the average 

number of clothes washer self-clean 

cycles in a year, and 295 represents the 

average number of clothes washer cycles 

in a year. 

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)). 

In the September 2010 NOPR, DOE 

noted that the proposed amendments to 

the residential clothes washer test 

procedure would incorporate a test 

standard that is accepted internationally 

for measuring power consumption in 

standby mode and off mode (IEC 

Standard 62301). DOE analyzed the 

available versions of IEC Standard 

62301 at that time—IEC Standard 62301 

(First Edition), IEC Standard 62301 

(CDV), and IEC Standard 62301 (FDIS)— 

and determined that the proposed 

amendments to the residential clothes 

washer test procedure would produce 

standby mode and off mode average 

power consumption measurements that 

are representative of an average use 

cycle. DOE also determined that the test 

methods and equipment that the 

amendments would require for 

measuring standby mode and off mode 

power in these products would not be 

substantially different from the test 

methods and equipment required in the 

current DOE test. Thus, DOE tentatively 

concluded that the proposed test 

procedure amendments would not 

require manufacturers to make 

significant investments in test facilities 

and new equipment. In sum, DOE 

tentatively concluded in the September 

2010 NOPR 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. 75 FR 57556, 

57578 (Sept. 21, 2010). 

DOE also noted in the September 

2010 NOPR that the proposed active 

mode amendments may require some 

manufacturers to incur equipment 

purchases on the order of hundreds of 

dollars, and would require testing 

additional cycles that could increase the 

total test time for certain clothes 

washers by approximately 25 percent. 

DOE tentatively concluded, however, 

that including these additional cycles in 

the test procedure would provide for a 

more representative measurement of 

machine energy efficiency and water 

use, and that the time commitment 

required to test these additional cycles 

would not represent a significant 

burden on manufacturers since the 

current test procedure already requires 

multiple energy test cycles. Id. 

Today’s supplemental proposed 

amendments to the DOE test procedures 

are based on an updated version of IEC 

Standard 62301, IEC Standard 62301 

(Second Edition). As discussed in 

section III.B.1 of this notice, DOE 

believes that the provisions of IEC 

Standard 62301 (Second Edition) that it 

proposes to incorporate by reference in 

today’s SNOPR provide a means to 

measure power consumption with 

greater accuracy and repeatability than 

the provisions from IEC Standard 62301 

(First Edition) that were originally 

proposed in the December 2010 NOPR. 

For this reason, DOE concludes that 

today’s supplemental proposed 

amendments would also provide 

measurements representative of average 

consumer use of the residential clothes 

washer under test. DOE further believes 

these new provisions in the applicable 

sections of IEC Standard 62301 (Second 

Edition) improve test results without 

undue testing burden. DOE also believes 

that the potential for increased test 

burden for certain power consumption 

measurements is offset by more 

reasonable requirements for testing 

equipment, while maintaining 

acceptable measurement accuracy. 


jlentini on DSK4TPTVN1PROD with PROPOSALS3
49252 Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules 

Thus, DOE tentatively concludes that 

the amended test procedures newly 

proposed in today’s SNOPR 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. 

The active mode provisions newly 

proposed in today’s SNOPR consist of 

clarifications to test conduct and revised 

calculations, and would not require any 

additional investment, equipment 

purchases, or test time beyond those 

described in the September 2010 NOPR. 

Therefore, DOE’s retains its tentative 

conclusion that the proposed active 

mode amendments would not impose a 

significant burden on manufacturers. 

2. Integration of Standby Mode and Off 

Mode Energy Consumption Into the 

Efficiency Metric 

Section 325(gg)(2)(A) of EPCA 

requires that standby mode and off 

mode energy consumption be integrated 

into the overall energy efficiency, 

energy consumption, or other energy 

descriptor for each covered product 

unless the current test procedures 

already fully account for the standby 

mode and off mode energy consumption 

or if an integrated test procedure is 

technically infeasible. (42 U.S.C. 

6295(gg)(2)(A)) 

Today’s SNOPR incorporates the 

clothes washer standby and off mode 

energy consumption into a ‘‘combined 

low-power mode’’ energy consumption, 

expressed in kWh, and converted into 

an IMEF, as discussed in section III.B.2 

of this notice. 

EPCA provides that test procedure 

amendments adopted to comply with 

the new EPCA requirements for standby 

and off mode energy consumption will 

not determine compliance with 

previously established standards. (42 

U.S.C. 6295(gg)(2)(C)) Because DOE is 

incorporating these changes in a new 

appendix J2 to 10 CFR part 430 subpart 

B that manufacturers would not be 

required to use until the compliance 

date of amended energy conservation 

standards for residential clothes 

washers, the test procedure 

amendments pertaining to standby 

mode and off mode energy consumption 

that DOE proposes to adopt in this 

rulemaking would not apply to, and 

would have no effect on, existing 

standards. 

3. 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) 

DOE noted in the September 2010 

NOPR that the impacts to testing 

commercial clothes washers would be 

limited to the proposed amendments 

associated with active washing mode 

because commercial clothes washer 

standards are based on MEF and WF. 

Among others, these include proposed 

changes to the test load size 

specification, temperature use factors, 

dryer usage factor (DUF), capacity 

measurement, and water supply 

pressure specification, all of which 

could affect the measured energy and 

water efficiencies of a commercial 

clothes washer. DOE believed that the 

most significant impacts could be 

associated with the proposed 

amendments for capacity measurement 

and usage factors, but did not have 

information to evaluate any impacts for 

commercial clothes washers. 75 FR 

57556, 57578 (Sept. 21, 2010). 

In response, DOE received several 

comments on potential impacts of an 

amended clothes washer test procedure 

on commercial clothes washers. In 

today’s SNOPR, DOE addresses those 

comments that pertain to the revised 

proposal. 

ALS commented that the most 

significant impact of the proposed 

amended test procedure on commercial 

clothes washers is the standby power 

measurement, because unlike most 

residential clothes washers, commercial 

clothes washers are vended and have 

lighted displays to invite customers to 

use them and provide instructions for 

use. According to ALS, the inclusion of 

standby power would significantly 

impact the ability for existing 

commercial clothes washers to meet 

more stringent minimum energy 

conservation standards without 

requiring a ready-to-use vended clothes 

washer to power down the display. ALS 

stated that a powered-down display 

would cause a potential customer to 

think the washer is not operational or 

ready to use, and thus discourage its 

use. (ALS, No. 10 at pp. 5–6). 

ALS also commented that the next 

most significant impact of the proposed 

amended test procedure would be the 

clothes container capacity measurement 

method, which would reduce the 

existing capacity rating. This would 

significantly reduce an already smaller 

tub used in commercial markets to even 

less volume measured, making it more 

difficult to achieve the minimum 

required energy efficiency standard. 

(ALS, No. 10 at p. 6) 

Whirlpool commented that the nature 

of use for commercial clothes washers 

would preclude the existence of delay 

start mode, cycle finished mode, and 

steam cycles. Whirlpool stated that the 

clothes washer test procedure should 

ignore those features if they are not on 

the unit under test. Whirlpool also 

expressed concern regarding the 

capacity measurement and modified 

temperature use factors. Whirlpool 

stated that the proposed IMEF and IWF 

calculations are suitable for commercial 

clothes washers. (Whirlpool, No. 13 at 

p. 14). 

In response to these comments, and as 

stated above, the impacts to testing 

commercial clothes washers would be 

limited to the proposed amendments 

associated with active washing mode 

because commercial clothes washer 

standards are based on MEF and WF. 

Because commercial clothes washer 

standards do not include standby and 

off mode, the addition of procedures to 

measure the energy use in standby and 

off modes would be inapplicable to and 

would not affect the standards for 

commercial clothes washers pursuant to 

42 U.S.C. 6293(e). For the active mode 

provisions of the proposed test 

procedure that could affect the 

measured energy and water efficiencies 

of a commercial clothes washer, DOE 

notes that 42 U.S.C. 6293(e)(3) provides 

the following: 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. 

DOE concurs that commercial clothes 

washers would not be affected by any 

provisions for measuring delay start 

mode, cycle finished mode, or steam 

cycles. Under the proposal in today’s 

SNOPR, the energy use for delay start 

and cycle finished modes would be 

included in the test results pursuant to 

the ‘‘alternate method’’ for measuring 

standby mode and off mode energy use, 

described in section III.B.2, and any 

such energy use is not included in the 

MEF and WF metrics used for 

commercial clothes washers. 

4. Certification Requirements 

Sections 6299–6305 and 6316 of 

EPCA authorize DOE to enforce 

compliance with the energy and water 


jlentini on DSK4TPTVN1PROD with PROPOSALS3
Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules 49253 

conservation standards established for 

certain consumer products and 

commercial equipment. (42 U.S.C. 

6299–6305 (consumer products), 6316 

(commercial equipment)) On March 7, 

2011, the Department revised, 

consolidated, and streamlined its 

existing certification, compliance, and 

enforcement regulations for certain 

consumer products and commercial and 

industrial equipment covered under 

EPCA, including residential clothes 

washers. 76 FR 12422. These regulations 

for residential clothes washers are 

codified in 10 CFR part 429.20. 

The certification requirements for 

residential clothes washers consist of a 

sampling plan for selection of units for 

testing and requirements for 

certification reports. Because the 

proposed amendments to the test 

procedure would not revise the current 

energy conservation standards, DOE is 

not proposing any amendments to the 

certification reporting requirements for 

these products. However, because DOE 

proposes in today’s SNOPR to introduce 

two new metrics (IMEF and IWF), DOE 

proposes amended provisions in the 

sampling plan in 10 CFR part 

429.20(a)(2) that would include IMEF 

along with the existing measure of MEF, 

and IWF along with the existing 

measure of WF. 

D. Impact on EnergyGuide 

In the September 2010 NOPR, DOE 

determined that the proposed test 

procedure amendments would not affect 

the FTC EnergyGuide labeling program 

because DOE did not propose to amend 

the estimated annual operating cost 

calculation in 10 CFR 430.23. 

NEEA commented that the energy use 

and annual energy cost information on 

the Energy Guide label is supposed to 

represent a reasonably accurate estimate 

of the annual energy use and energy cost 

associated with the use of the labeled 

product. NEEA stated that it would be 

nearly impossible to justify any rules 

associated with the accuracy of such 

representations if whole categories of 

annual energy use and cost are ignored. 

NEEA stated that Congress intended to 

account for the energy use of every 

appliance in its inactive mode and to 

make the results known to consumers. 

(NEEA, No.12 at p. 8) 

NEEA also noted that the ratings of 

many models may change as a result of 

the revised test procedure. NEEA 

commented that the EnergyGuide labels 

for individual models tested under 

appendix J1 and appendix J2 will exist 

in the marketplace together for a short 

time, raising the likelihood of consumer 

confusion when this happens. 

According to NEEA, there has been 

considerable consumer confusion in the 

past when new models arrive with 

energy use and annual cost numbers 

that are lower (or higher) than the 

lowest (or highest) numbers in the range 

on the EnergyGuide label. (NEEA, No. 

12 at pp.15–16). 

The Joint Comment stated that the 

EnergyGuide label is designed to 

communicate to consumers the 

estimated average annual operating cost 

of a given product. Since the annual 

operating cost for a washer that a 

consumer will incur includes the cost of 

energy consumed in all modes 

including self-clean, standby, off, delay 

start, and cycle finished modes, the 

operating costs of all modes should be 

included in the annual operating cost 

calculation. (Joint Comment, No. 16 at 

p. 2). 

In addition, the Joint Comment stated 

that the cost of energy consumed in the 

additional non-active modes for many 

products will likely be significant 

compared to the total energy cost, which 

DOE estimates could consume as much 

as 48 kWh/year. The Joint Commenters 

noted that the EnergyGuide label 

includes only the cost of the machine 

energy and the water heating energy, 

and does not include the cost of the 

energy required to remove the 

remaining moisture from the clothes, 

which makes the cost of energy 

consumed in non-active-washing modes 

more significant. According to the Joint 

Comment, the most efficient washers 

listed by the FTC with a capacity greater 

than 3 cubic feet only use about 110– 

130 kWh/year, and, therefore, the 

energy consumed in modes other than 

the active washing mode could 

represent up to about 40 percent of total 

annual energy use, which is significant. 

(Joint Comment, No. 16 at pp. 2–3). 

Whirlpool objected to measuring 

additional energy use in non-active 

modes but not reporting them on the 

EnergyGuide tag, stating that this would 

be inconsistent. (Whirlpool, Public 

Meeting Transcript, No. 20 at pp. 95– 

96). 

ASAP commented that when the new 

standards go into effect, the minimum 

and maximum operating costs on the 

EnergyGuide label would have to be 

revised anyway to take into account the 

new standards, and that the additional 

annual operating costs could be 

incorporated at that point. ASAP stated 

that it supports incorporating all energy 

use, including energy use in non-active 

modes. (ASAP, Public Meeting 

Transcript, No. 20 at p. 96). 

As discussed in section III.B.6, DOE 

proposes in today’s SNOPR to amend 

the estimated annual operating cost by 

incorporating the cost of energy 

consumed in the non-active washing 

modes. DOE also proposed in the 

September 2010 NOPR to update the 

number of annual use cycles. This will 

affect the estimated annual operating 

cost disclosed on the EnergyGuide label. 

Pursuant to 42 U.S.C. 6294, the FTC 

may revise the EnergyGuide label for 

residential clothes washers when the 

amended test procedure becomes 

effective. 

IV. Procedural Issues and Regulatory 

Review 

A. Review Under Executive Order 12866 

The Office of Management and Budget 

has determined that test procedure 

rulemakings do not constitute 

‘‘significant regulatory actions’’ under 

section 3(f) of Executive Order 12866, 

Regulatory Planning and Review, 58 FR 

51735 (Oct. 4, 1993). Accordingly, this 

action was not subject to review under 

the Executive Order by the Office of 

Information and Regulatory Affairs 

(OIRA) in the Office of Management and 

Budget (OMB). 

B. Review Under the Regulatory 

Flexibility Act 

The Regulatory Flexibility Act (5 

U.S.C. 601 et seq.) requires preparation 

of 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 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 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

7A searchable database of certified small 

businesses is available online at: http://dsbs.sba.

gov/dsbs/search/dsp_dsbs.cfm. 

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 7 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 incorporating 

testing provisions to address active 

mode, standby mode, and off mode 

energy and water consumption that will 

be used to demonstrate compliance with 

energy conservation standards. The 

proposed test procedure amendments 

for measuring standby and off mode 

power consumption using the 

‘‘alternative method’’ involve measuring 

power input when the clothes washer is 

in inactive mode or off mode, or both if 

both modes are available on the clothes 

washer under test, as a proxy for 

measuring power consumption in all 

low power modes. These tests can be 

conducted in the same facilities used for 

the current energy testing of these 

products, so it is anticipated that 

manufacturers would not incur any 

additional facilities costs as a result of 

the proposed test procedure 

amendments. The power meter required 

for these tests might require greater 

accuracy than the power meter used for 

current energy testing, but the 

investment required for a possible 

instrumentation upgrade is expected to 

be approximately a few thousand 

dollars. The duration of each non-active 

washing mode test period is expected to 

be roughly 30–45 minutes, depending 

on stability of the power consumption, 

using the alternative approach described 

previously. This is comparable to 

approximately one-half to two-thirds the 

time required to conduct a single energy 

test cycle. Each clothes washer tested 

requires, on average, approximately 15 

test cycles for energy testing, which 

equates to about 3 days of testing. Using 

the alternative approach proposed in 

today’s SNOPR, DOE estimates roughly 

a 3-percent increase in total test period 

duration. This represents a significant 

reduction compared to the 11 percent 

increase DOE estimated in the 

September 2010 NOPR, which was 

based on the proposal to measure 

inactive, off, delay start, and cycle 

finished modes separately. DOE notes 

that the provisions from IEC Standard 

62301 (Second Edition) proposed to 

incorporate by reference in today’s 

SNOPR would require longer test 

durations in the event that the threshold 

stability criteria of the power 

measurement are not met. DOE believes 

that the likelihood of such a longer test 

being required is very small, based on 

the observations during testing for the 

September 2010 NOPR. 

DOE also estimates that it costs a 

manufacturer approximately $2300 on 

average, including the cost of 

consumables, to conduct energy testing 

for a particular clothes washer. DOE 

further estimates that the cost of 

additional testing for non-active 

washing modes using the proposed 

alternative approach would average $75 

per machine, a 3-percent increase over 

current test costs. This represents a 

significant reduction compared to the 9 

percent increase ($200) DOE estimated 

in the September 2010 NOPR, which 

was based on the proposal to measure 

inactive, off, delay start, and cycle 

finished modes separately. For the same 

reason as discussed above, DOE does 

not believe it is likely that these test 

costs will be higher due to extended test 

times required by IEC Standard 62301 

(Second Edition) in the event that the 

threshold stability criteria of the power 

measurement are not met. 

DOE believes these additional 

requirements for equipment and time 

and additional cost to conduct the 

proposed non-active washing mode test 

would not be expected to impose a 

significant economic burden on entities 

subject to the applicable testing 

requirements. Although the small 

business has significantly lower sales 

than other manufacturers over which to 

amortize these additional costs, it 

produces only a single platform which 

would be subject to the proposed nonactive washing mode tests. 

DOE does not believe that the 

proposed test procedure amendments 

for the active washing mode discussed 

in today’s SNOPR would increase test 

burden because they comprise revisions 

to calculations rather than additional, 

longer, or more complex methodology. 

For standby mode and off mode, as 

described in section III.B.1, certain 

provisions in section 5 of IEC Standard 

62301 Second Edition could require 

additional testing time compared to the 

First Edition. However, DOE expects the 

large majority of clothes washers to 

require less than one hour of testing 

time to perform the standby power test 

under the proposed alternative 

approach. Therefore, DOE does not 

believe these proposed amendments 

would have a significant impact on a 

substantial number of small entities. 

For these reasons, DOE tentatively 

concludes and certifies that the 

September 2010 NOPR, as modified by 

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). 

DOE seeks comment on the updated 

certification set forth above. 

C. Review Under the Paperwork 

Reduction Act of 1995 

Manufacturers of residential clothes 

washers must certify to DOE that their 

products comply with any applicable 

energy conservation standards. In 

certifying compliance, manufacturers 

must test their products according to the 

DOE test procedures for clothes 

washers, including any amendments 

adopted for those test procedures. DOE 

has established regulations for the 

certification and recordkeeping 

requirements for all covered consumer 

products and commercial equipment, 

including residential clothes washers. 

76 FR 12422 (March 7, 2011). The 

collection-of-information requirement 

for the certification and recordkeeping 

is subject to review and approval by 

OMB under the Paperwork Reduction 

Act (PRA). This requirement has been 

approved by OMB under OMB control 

number 1910–1400. Public reporting 

burden for the certification is estimated 

to average 20 hours per response, 

including the time for reviewing 

instructions, searching existing data 

sources, gathering and maintaining the 

data needed, and completing and 

reviewing the collection of information. 

Notwithstanding any other provision 

of the law, no person is required to 

respond to, nor shall any person be 

subject to a penalty for failure to comply 

with, a collection of information subject 

to the requirements of the PRA, unless 

that collection of information displays a 

currently valid OMB Control Number.

Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules 49255 

D. Review Under the National 

Environmental Policy Act of 1969 

In this proposed rule, DOE proposes 

test procedure amendments that it 

expects will be used to develop and 

implement future energy conservation 

standards for residential clothes 

washers. DOE has determined that this 

rule falls into a class of actions that are 

categorically excluded from review 

under the National Environmental 

Policy Act of 1969 (42 U.S.C. 4321 et 

seq.) and DOE’s implementing 

regulations at 10 CFR part 1021. 

Specifically, this proposed rule would 

amend the existing test procedures 

without affecting the amount, quality or 

distribution of energy usage, and, 

therefore, would not result in any 

environmental impacts. Thus, this 

rulemaking is covered by Categorical 

Exclusion A5 under 10 CFR part 1021, 

subpart D, which applies to any 

rulemaking that interprets or amends an 

existing rule without changing the 

environmental effect of that rule. 

Accordingly, neither an environmental 

assessment nor an environmental 

impact statement is required. 

E. Review Under Executive Order 13132 

Executive Order 13132, ‘‘Federalism,’’ 

64 FR 43255 (August 4, 1999) imposes 

certain requirements on agencies 

formulating and implementing policies 

or regulations that preempt State law or 

that have Federalism implications. The 

Executive Order requires agencies to 

examine the constitutional and statutory 

authority supporting any action that 

would limit the policymaking discretion 

of the States and to carefully assess the 

necessity for such actions. The 

Executive Order also requires agencies 

to have an accountable process to 

ensure meaningful and timely input by 

State and local officials in the 

development of regulatory policies that 

have Federalism implications. On 

March 14, 2000, DOE published a 

statement of policy describing the 

intergovernmental consultation process 

it will follow in the development of 

such regulations. 65 FR 13735. DOE has 

examined this proposed rule and has 

determined that it would not have a 

substantial direct effect on the States, on 

the relationship between the national 

government and the States, or on the 

distribution of power and 

responsibilities among the various 

levels of government. EPCA governs and 

prescribes Federal preemption of State 

regulations as to energy conservation for 

the products that are the subject of 

today’s proposed rule. States can 

petition DOE for exemption from such 

preemption to the extent, and based on 

criteria, set forth in EPCA. (42 U.S.C. 

6297(d)) No further action is required by 

Executive Order 13132. 

F. Review Under Executive Order 12988 

Regarding the review of existing 

regulations and the promulgation of 

new regulations, section 3(a) of 

Executive Order 12988, ‘‘Civil Justice 

Reform,’’ 61 FR 4729 (Feb. 7, 1996), 

imposes on Federal agencies the general 

duty to adhere to the following 

requirements: (1) Eliminate drafting 

errors and ambiguity; (2) write 

regulations to minimize litigation; (3) 

provide a clear legal standard for 

affected conduct rather than a general 

standard; and (4) promote simplification 

and burden reduction. Section 3(b) of 

Executive Order 12988 specifically 

requires that Executive agencies make 

every reasonable effort to ensure that the 

regulation: (1) Clearly specifies the 

preemptive effect, if any; (2) clearly 

specifies any effect on existing Federal 

law or regulation; (3) provides a clear 

legal standard for affected conduct 

while promoting simplification and 

burden reduction; (4) specifies the 

retroactive effect, if any; (5) adequately 

defines key terms; and (6) addresses 

other important issues affecting clarity 

and general draftsmanship under any 

guidelines issued by the Attorney 

General. Section 3(c) of Executive Order 

12988 requires Executive agencies to 

review regulations in light of applicable 

standards in sections 3(a) and 3(b) to 

determine whether they are met or it is 

unreasonable to meet one or more of 

them. DOE has completed the required 

review and determined that, to the 

extent permitted by law, the proposed 

rule meets the relevant standards of 

Executive Order 12988. 

G. Review Under the Unfunded 

Mandates Reform Act of 1995 

Title II of the Unfunded Mandates 

Reform Act of 1995 (UMRA) requires 

each Federal agency to assess the effects 

of Federal regulatory actions on State, 

local, and Tribal governments and the 

private sector. Public Law 104–4, sec. 

201 (codified at 2 U.S.C. 1531). For a 

proposed regulatory action likely to 

result in a rule that may cause the 

expenditure by State, local, and Tribal 

governments, in the aggregate, or by the 

private sector of $100 million or more 

in any one year (adjusted annually for 

inflation), section 202 of UMRA requires 

a Federal agency to publish a written 

statement that estimates the resulting 

costs, benefits, and other effects on the 

national economy. (2 U.S.C. 1532(a), (b)) 

The UMRA also requires a Federal 

agency to develop an effective process 

to permit timely input by elected 

officers of State, local, and Tribal 

governments on a proposed ‘‘significant 

intergovernmental mandate,’’ and 

requires an agency plan for giving notice 

and opportunity for timely input to 

potentially affected small governments 

before establishing any requirements 

that might significantly or uniquely 

affect small governments. On March 18, 

1997, DOE published a statement of 

policy on its process for 

intergovernmental consultation under 

UMRA. 62 FR 12820; also available at 

http://www.gc.doe.gov. DOE examined 

today’s proposed rule according to 

UMRA and its statement of policy and 

determined that the rule contains 

neither an intergovernmental mandate, 

nor a mandate that may result in the 

expenditure of $100 million or more in 

any year, so these requirements do not 

apply. 

H. Review Under the Treasury and 

General Government Appropriations 

Act, 1999 

Section 654 of the Treasury and 

General Government Appropriations 

Act, 1999 (Pub. L. 105–277) requires 

Federal agencies to issue a Family 

Policymaking Assessment for any rule 

that may affect family well-being. This 

rule would not have any impact on the 

autonomy or integrity of the family as 

an institution. Accordingly, DOE has 

concluded that it is not necessary to 

prepare a Family Policymaking 

Assessment. 

I. Review Under Executive Order 12630 

DOE has determined, under Executive 

Order 12630, ‘‘Governmental Actions 

and Interference with Constitutionally 

Protected Property Rights’’ 53 FR 8859 

(March 18, 1988), that this regulation 

would not result in any takings that 

might require compensation under the 

Fifth Amendment to the U.S. 

Constitution. 

J. Review Under Treasury and General 

Government Appropriations Act, 2001 

Section 515 of the Treasury and 

General Government Appropriations 

Act, 2001 (44 U.S.C. 3516 note) provides 

for agencies to review most 

disseminations of information to the 

public under guidelines established by 

each agency pursuant to general 

guidelines issued by OMB. OMB’s 

guidelines were published at 67 FR 

8452 (Feb. 22, 2002), and DOE’s 

guidelines were published at 67 FR 

62446 (Oct. 7, 2002). DOE has reviewed 

today’s proposed rule under the OMB 

and DOE guidelines and has concluded 

that it is consistent with applicable 

policies in those guidelines. 


jlentini on DSK4TPTVN1PROD with PROPOSALS3
49256 Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules 

K. Review Under Executive Order 13211 

Executive Order 13211, ‘‘Actions 

Concerning Regulations That 

Significantly Affect Energy Supply, 

Distribution, or Use,’’ 66 FR 28355 (May 

22, 2001), requires Federal agencies to 

prepare and submit to OMB, a 

Statement of Energy Effects for any 

proposed significant energy action. A 

‘‘significant energy action’’ is defined as 

any action by an agency that 

promulgated or is expected to lead to 

promulgation of a final rule, and that: 

(1) Is a significant regulatory action 

under Executive Order 12866, or any 

successor order; and (2) is likely to have 

a significant adverse effect on the 

supply, distribution, or use of energy; or 

(3) is designated by the Administrator of 

OIRA as a significant energy action. For 

any proposed significant energy action, 

the agency must give a detailed 

statement of any adverse effects on 

energy supply, distribution, or use 

should the proposal be implemented, 

and of reasonable alternatives to the 

action and their expected benefits on 

energy supply, distribution, and use. 

Today’s regulatory action to amend 

the test procedure for measuring the 

energy efficiency of residential clothes 

washers is not a significant regulatory 

action under Executive Order 12866. 

Moreover, it would not have a 

significant adverse effect on the supply, 

distribution, or use of energy, nor has it 

been designated as a significant energy 

action by the Administrator of OIRA. 

Therefore, it is not a significant energy 

action, and, accordingly, DOE has not 

prepared a Statement of Energy Effects. 

L. Review Under Section 32 of the 

Federal Energy Administration Act of 

1974 

Under section 301 of the Department 

of Energy Organization Act (Pub. L. 95– 

91; 42 U.S.C. 7101), DOE must comply 

with section 32 of the Federal Energy 

Administration Act of 1974, as amended 

by the Federal Energy Administration 

Authorization Act of 1977. (15 U.S.C. 

788; FEAA) Section 32 essentially 

provides in relevant part that, where a 

proposed rule authorizes or requires use 

of commercial standards, the notice of 

proposed rulemaking must inform the 

public of the use and background of 

such standards. In addition, section 

32(c) requires DOE to consult with the 

Attorney General and the Chairman of 

the FTC concerning the impact of the 

commercial or industry standards on 

competition. 

The proposed modifications to the 

test procedure addressed by this action 

incorporate testing methods contained 

in the commercial standard, IEC 

Standard 62301, Edition 2.0 2011–01, 

‘‘Household electrical appliances— 

Measurement of standby power.’’ DOE 

has evaluated this standard and is 

unable to conclude whether it fully 

complies with the requirements of 

section 32(b) of the FEAA (i.e., whether 

it was developed in a manner that fully 

provides for public participation, 

comment, and review.) DOE will 

consult with the Attorney General and 

the Chairman of the FTC about the 

impact on competition of using the 

methods contained in this standard, 

before prescribing a final rule. 

V. Public Participation

one copy of the document marked 

confidential including all the 


jlentini on DSK4TPTVN1PROD with PROPOSALS3
Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules 49257 

information believed to be confidential, 

and one copy of the document marked 

non-confidential with the information 

believed to be confidential deleted. 

Submit these documents via e-mail or 

on a CD, if feasible. DOE will make its 

own determination about the 

confidential status of the information 

and treat it according to its 

determination. 

Factors of interest to DOE when 

evaluating requests to treat submitted 

information as confidential include: (1) 

A description of the items; (2) whether 

and why such items are customarily 

treated as confidential within the 

industry; (3) whether the information is 

generally known by or available from 

other sources; (4) whether the 

information has previously been made 

available to others without obligation 

concerning its confidentiality; (5) an 

explanation of the competitive injury to 

the submitting person which would 

result from public disclosure; (6) when 

such information might lose its 

confidential character due to the 

passage of time; and (7) why disclosure 

of the information would be contrary to 

the public interest. 

It is DOE’s policy that all comments 

may be included in the public docket, 

without change and as received, 

including any personal information 

provided in the comments (except 

information deemed to be exempt from 

public disclosure). 

B. Issues on Which DOE Seeks Comment 

Although DOE welcomes comments 

on any aspect of this proposal, DOE is 

particularly interested in receiving 

comments and views of interested 

parties concerning the following issues: 

(1) Incorporation by reference of 

certain provisions of IEC 62301 (Second 

Edition), and the accompanying impacts 

on measurement improvement and test 

burden (see section III.B.1); 

(2) The acceptability of measuring the 

total harmonic content, crest factor, and 

maximum current ratio before and after 

the actual test measurement if the power 

measuring instrument is unable to 

perform these measurements during the 

actual test measurement; 

(3) The potential test burden that 

would be required for a laboratory to 

upgrade its data acquisition system to 

enable real-time statistical analysis 

capabilities; 

(4) The alternate method for 

measuring energy use in low-power 

modes by means of measuring power 

consumption only in the inactive mode 

and off mode (see section III.B.2); 

(5) The proposed clarification of the 

energy test cycle definition (see section 

III.B.3); 

(6) The proposed use of a weightedaverage load size based on the load 

usage factors and the minimum, 

average, and maximum load sizes rather 

than the product of the LAF and 

maximum load size in the drying energy 

calculation (see section III.B.4); and 

(7) The proposed clarification of how 

to classify the wash temperature settings 

for clothes washers with both a ‘‘cold’’ 

wash setting and a ‘‘tap cold’’ wash 

setting. 

(8) DOE’s tentative conclusion and 

certification that the September 2010 

NOPR, as modified by today’s SNOPR, 

would not have a significant economic 

impact on a substantial number of small 

entities.

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 

for residential clothes washers. After this 

date, all residential clothes washers shall be 

tested using the provisions of Appendix J2 of 

this appendix. 

* * * * * 

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 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 


jlentini on DSK4TPTVN1PROD with PROPOSALS3
Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules 49259 

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.

Appendix J1 is effective until the 

compliance date of any amended 

standards for residential clothes 

washers. After this date, all residential 

clothes washers shall be tested using the 

provisions of Appendix J2. 

1. Definitions and Symbols 

1.1 Active mode means a mode in 

which the clothes washer is connected 

to a mains power source, has been 

activated, and is performing one or more 

of the main functions of washing, 

soaking, tumbling, agitating, rinsing, 

and/or removing water from the 

clothing, or is involved in functions 

necessary for these main functions, such 

as admitting water into the washer or 

pumping water out of the washer. 

Active mode also includes delay start, 

cycle finished, and self-clean modes. 

1.2 Active washing mode means a 

mode in which the clothes washer is 

performing any of the operations 

included in a complete cycle intended 

for washing a clothing load, including 

the main functions of washing, soaking, 

tumbling, agitating, rinsing, and/or 

removing water from the clothing. 

1.3 Adaptive control system means a 

clothes washer control system, other 

than an adaptive water fill control 

system, which is capable of 

automatically adjusting washer 

operation or washing conditions based 

on characteristics of the clothes load 

placed in the clothes container, without 

allowing or requiring consumer 

intervention or actions. The automatic 

adjustments may, for example, include 

automatic selection, modification, or 

control of any of the following: Wash 

water temperature, agitation or tumble 

cycle time, number of rinse cycles, and 

spin speed. The characteristics of the

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 ft3), 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.

2.8.1 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, 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. 

2.9.2 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). 

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 frontloading, 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. 

(1) 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. 

(2) 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. (1) 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 kilowatthours, and the cycles of usage. 

(2) 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:

Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules 49273 

A × (D/B) = G kWh per year 

6.3 Adaptive water fill control 

system field test. (1) Section 3.2.3.1 of 

this Appendix defines the test method 

for measuring energy consumption for 

clothes washers which incorporate 

control systems having both adaptive 

and alternate cycle selections. Energy 

consumption calculated by the method 

defined in section 3.2.3.1 of this 

Appendix assumes the adaptive cycle 

will be used 50 percent of the time. This 

section can be used to develop field test 

data in support of a petition for waiver 

when it is believed that the adaptive 

cycle will be used more than 50 percent 

of the time. The field test sample size 

should be a minimum of 10 test clothes 

washers. The test clothes washers 

should be representative of the design, 

construction, and control system that 

will be placed in commerce. The 

duration of field testing in the user’s 

house should be a minimum of 50 

energy test cycles, for each unit. No 

special instructions as to cycle selection 

or product usage should be given to the 

field test participants, other than 

inclusion of the product literature pack 

which would be shipped with all units, 

and instructions regarding filling out 

data collection forms, use of data 

collection equipment, or basic 

procedural methods. Prior to the test 

clothes washers being installed in the 

field test locations, baseline data should 

be developed for all field test units by 

conducting laboratory tests as defined 

by section 1 through section 5 of this 

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) 

(2) Energy consumption (HET, MET, and 

DE) and water consumption (QT), values 

calculated in section 4 of this Appendix for 

the manual and adaptive modes, should be 

combined using Pa and Pm as the weighting 

factors.
