[Docket No. EERE–2010–BT–TP–0039] 

RIN 1904–AC27 

Energy Conservation Program: Test 

Procedures for Residential 

Dishwashers, Dehumidifiers, and 

Conventional Cooking Products 

(Standby Mode and Off Mode) 

AGENCY: Office of Energy Efficiency and 

Renewable Energy, Department of 

Energy. 

ACTION: Supplemental notice of 

proposed rulemaking. 

SUMMARY: Where appropriate, the U.S. 

Department of Energy (DOE) has 

proposed to amend its test procedures 

for residential dishwashers, 

dehumidifiers, and conventional 

cooking products (which includes 

cooktops, ovens, and ranges) to include 

provisions for measuring standby mode 

and off mode energy consumption, as 

required by the Energy Independence 

and Security Act of 2007 (EISA 2007). 

These test procedure amendments 

would incorporate by reference certain 

provisions of the International 

Electrotechnical Commission (IEC) 

Standard 62301, ‘‘Household electrical 

appliances—Measurement of standby 

power.’’ Since publication of DOE’s 

initial proposal in December 2010, the 

IEC has replaced the First Edition of this 

standard with the current Second 

Edition. This supplemental notice of 

proposed rulemaking proposes to 

incorporate the latest edition of IEC 

Standard 62301. 

DATES: DOE will accept comments, data, 

and information regarding this 

supplemental notice of proposed 

rulemaking (SNOPR) submitted no later 

than October 20, 2011. See section 0, 

‘‘Public Participation,’’ for details.

Title III, Part B1 of the Energy Policy

the Act), Public Law 94–163 (42 U.S.C. 

6291–6309, as codified) sets forth a

2All references to EPCA in this rulemaking refer 

to the statute as amended through the Energy 

Independence and Security Act of 2007, Public Law 

110–140. 

3The term ‘‘conventional cooking products,’’ as 

used in this notice, refers to residential electric and 

gas kitchen ovens, ranges, and cooktops (other than 

microwave ovens). 

4EISA 2007 directs DOE to also consider IEC 

Standard 62087 when amending its test procedures 

to include standby mode and off mode energy 

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

However, IEC Standard 62087 addresses the 

methods of measuring the power consumption of 

audio, video, and related equipment. Accordingly, 

the narrow scope of this particular IEC standard 

reduces its relevance to today’s proposal. 

5For more information on the ENERGY STAR 

program, see: http://www.energystar.gov. 

variety of provisions designed to 

improve energy efficiency and 

established the Energy Conservation 

Program for Consumer Products Other 

Than Automobiles, a program covering 

most major household appliances.2

These include residential dishwashers, 

conventional cooking products,3 and 

dehumidifiers, the subject of today’s 

notice. (42 U.S.C. 6292(a)(6) and (10); 

6295(cc)) 

Under the Act, this program consists 

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

labeling, (3) establishing Federal energy 

conservation standards, and (4) 

certification and enforcement 

procedures. The testing requirements 

consist of test procedures that 

manufacturers of covered products must 

use: (1) As the basis for certifying to 

DOE that their products comply with 

applicable energy conservation 

standards adopted pursuant to EPCA, 

and (2) for making representations about 

the efficiency of those products. (42 

U.S.C. 6293(c); 6295(s)) Similarly, DOE 

must use these test procedures in any 

enforcement action to determine 

whether the products comply with these 

energy conservation standards. (42 

U.S.C. 6295(s)) 

A. 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 

‘‘[a]ny test procedures prescribed or 

amended under this section shall be 

reasonably designed to produce test 

results which measure energy 

efficiency, energy use * * * or 

estimated annual operating cost of a 

covered product during a representative 

average use cycle or period of use, as 

determined by the Secretary [of Energy], 

and shall not be unduly burdensome to 

conduct.’’ (42 U.S.C. 6293(b)(3)) 

In addition, if DOE determines that a 

test procedure amendment is warranted, 

it must publish proposed test 

procedures and 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)) 

On December 19, 2007, the Energy 

Independence and Security Act of 2007 

(EISA 2007), Public Law 110–140, was 

enacted. The EISA 2007 amendments to 

EPCA, in relevant part, require DOE to 

amend the test procedures for all 

residential covered products to include 

measures of standby mode and off mode 

energy consumption. Specifically, 

section 310 of EISA 2007 provides 

definitions of ‘‘standby mode’’ and ‘‘off 

mode’’ (42 U.S.C. 6295(gg)(1)(A)) and 

permits DOE to amend these definitions 

in the context of a given product (42 

U.S.C. 6295(gg)(1)(B)). The statute 

requires integration of such energy 

consumption ‘‘into the overall energy 

efficiency, energy consumption, or other 

energy descriptor for each covered 

product, unless the Secretary 

determines that— 

(i) The current test procedures for a 

covered product already fully account 

for and incorporate the standby mode 

and off mode energy consumption of the 

covered product; or 

(ii) Such an integrated test procedure 

is technically infeasible for a particular 

covered product, in which case the 

Secretary shall 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)) 

Under the statutory provisions 

adopted by EISA 2007, any such 

amendment must consider the most 

current versions of IEC Standard 62301, 

‘‘Household electrical appliances— 

Measurement of standby power,’’ and 

IEC Standard 62087, ‘‘Methods of 

measurement for the power 

consumption of audio, video, and 

related equipment.’’ 4 Id. At the time of 

the enactment of EISA 2007, the most 

current versions of these standards were 

IEC Standard 62301 (First Edition 2005– 

06) and IEC Standard 62087 (Second 

Edition 2008–09). 

1. Dishwashers 

DOE’s test procedure for dishwashers 

is found in the Code of Federal 

Regulations (CFR) at 10 CFR part 430, 

subpart B, appendix C. DOE originally 

established its test procedure for 

dishwashers in 1977. 42 FR 39964 

(August 8, 1977). Since that time, the 

dishwasher test procedure has 

undergone a number of amendments, as 

discussed below. In 1983, DOE 

amended the test procedure to revise the 

representative average-use cycles to 

more accurately reflect consumer use 

and to address dishwashers that use 120 

°F inlet water. 48 FR 9202 (March 3, 

1983). DOE amended the test procedure 

again in 1984 to redefine the term 

‘‘water heating dishwasher.’’ 49 FR 

46533 (Nov. 27, 1984). In 1987, DOE 

amended the test procedure to address 

models that use 50 °F inlet water. 52 FR 

47549 (Dec. 15, 1987). In 2001, DOE 

revised the test procedure’s testing 

specifications to improve testing 

repeatability, changed the definitions of 

‘‘compact dishwasher’’ and ‘‘standard 

dishwasher,’’ and reduced the average 

number of use cycles per year from 322 

to 264. 66 FR 65091, 65095–97 (Dec. 18, 

2001). In 2003, DOE again revised the 

test procedure to more accurately 

measure dishwasher efficiency, energy 

use, and water use. The 2003 

dishwasher test procedure amendments 

included the following revisions: (1) the 

addition of a method to rate the 

efficiency of soil-sensing products; (2) 

the addition of a method to measure 

standby power; and (3) A reduction in 

the average-use cycles per year from 264 

to 215. 68 FR 51887, 51899–903 (August 

29, 2003). The current version of the test 

procedure includes provisions for 

determining estimated annual energy 

use (EAEU), estimated annual operating 

cost (EAOC), energy factor (EF) 

expressed in cycles per kilowatt-hour 

(kWh), and water consumption 

expressed in gallons per cycle. 10 CFR 

430.23(c). 

2. Dehumidifiers 

The DOE test procedure for 

dehumidifiers is found at 10 CFR 430, 

subpart B, appendix X. The Energy 

Policy Act of 2005 (EPACT 2005), 

Public Law 109–58, amended EPCA to 

specify that the U.S. Environmental 

Protection Agency’s (EPA) test criteria 

used under the ENERGY STAR® 5

program must serve as the basis for the 

test procedure for dehumidifiers. 

(EPACT 2005, section 135(b); 42 U.S.C. 

6293(b)(13)) The ENERGY STAR test 

criteria require that American National 

Standards Institute (ANSI)/Association 

of Home Appliance Manufacturers 

(AHAM) Standard DH–1–2003,

labeling program, see: http://www.access.gpo.gov/ 

nara/cfr/waisidx_00/16cfr305_00.html. 

7EISA 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). 

However, IEC Standard 62087 addresses the 

methods of measuring the power consumption of 

audio, video, and related equipment. The narrow 

scope of this particular IEC standard reduces its 

relevance to today’s proposal. 

‘‘Dehumidifiers,’’ be used to measure 

energy use and that the Canadian 

Standards Association (CAN/CSA) 

standard CAN/CSA–C749–1994 

(R2005), ‘‘Performance of 

Dehumidifiers,’’ be used to calculate EF. 

DOE has adopted these test criteria, 

along with related definitions and 

tolerances, as its test procedure for 

dehumidifiers. 71 FR 71340, 71347, 

71366–68 (Dec. 8, 2006). The DOE test 

procedure provides methods for 

determining the EF for dehumidifiers, 

which is expressed in liters (l) of water 

condensed per kWh. 

3. Conventional Cooking Products 

DOE’s test procedures for 

conventional ranges, cooktops, and 

ovens (including microwave ovens) are 

found at 10 CFR 430, subpart B, 

appendix I. DOE first established the 

test procedures included in appendix I 

in a final rule published in the Federal 

Register on May 10, 1978. 43 FR 20108, 

20120–28. DOE revised its test 

procedure for cooking products to more 

accurately measure their efficiency and 

energy use, and published the revisions 

as a final rule in 1997. 62 FR 51976 

(Oct. 3, 1997). These test procedure 

amendments included: (1) a reduction 

in the annual useful cooking energy; (2) 

a reduction in the number of selfcleaning oven cycles per year; and (3) 

incorporation of portions of IEC 

Standard 705–1988, ‘‘Methods for 

measuring the performance of 

microwave ovens for household and 

similar purposes,’’ and Amendment 2– 

1993 for the testing of microwave ovens. 

Id. The test procedure for conventional 

cooking products establishes provisions 

for determining EAOC, cooking 

efficiency (defined as the ratio of 

cooking energy output to cooking energy 

input), and EF (defined as the ratio of 

annual useful cooking energy output to 

total annual energy input). 10 CFR 

430.23(i); 10 CFR 430 subpart B, 

appendix I. These provisions for 

conventional cooking products are not 

currently used for compliance with any 

energy conservation standards (because 

those standards currently involve design 

requirements), nor is there an 

EnergyGuide 6 labeling program for 

cooking products. 

DOE has initiated a separate test 

procedure rulemaking to address 

standby mode and off mode power 

consumption for microwave ovens. This 

rulemaking was initiated separately in 

response to comments from interested 

parties on the advance notice of 

proposed rulemaking (ANOPR) for an 

earlier rulemaking concerning energy 

conservation standards for residential 

dishwashers, dehumidifiers, cooking 

products, and commercial clothes 

washers published on November 15, 

2007 (hereafter referred to as the 

November 2007 ANOPR) (72 FR 64432), 

prior to the enactment of EISA 2007. As 

discussed in the subsequent notice of 

proposed rulemaking (NOPR) for that 

standards rulemaking, interested parties 

stated generally that DOE should amend 

the test procedures for all types of 

cooking products to allow for 

measurement of standby mode energy 

use in order to implement a standby 

power energy conservation standard. 73 

FR 62034, 62043–44 (Oct. 17, 2008). 

However, DOE did not receive any 

specific data or inputs on standby 

power consumption in conventional 

cooking products. Also, at that time, 

interested parties did not submit any 

comments regarding DOE addressing 

new measures of standby mode and off 

mode energy use in the test procedures 

or energy conservation standards for the 

other products that were the subject of 

the November 2007 ANOPR (i.e., 

dishwashers and dehumidifiers). 

Because DOE agreed with the comments 

supporting new measures of standby 

mode and off mode energy use for 

microwave ovens and the potential for 

early adoption of an energy 

conservation standard for microwave 

ovens addressing standby mode and off 

mode energy consumption, DOE 

published a NOPR proposing 

amendments to just the microwave oven 

test procedure for standby mode and off 

mode in the Federal Register on 

October 17, 2008. 73 FR 62134. DOE 

subsequently published a supplemental 

notice of proposed rulemaking (SNOPR) 

in the Federal Register on this topic on 

July 22, 2010 (75 FR 42612), and an 

interim final rule on March 9, 2011 

(hereafter referred to as the March 2011 

Interim Final Rule) (76 FR 12825). DOE 

issued this as an interim final rule in 

order to allow comment on a newly 

issued version of IEC Standard 62301 

(which is discussed in more detail in 

the following section) for measuring 

standby mode and off mode energy use, 

the previous version of which was 

incorporated by reference in the 

microwave oven test procedure. 

Consequently, DOE is proposing 

amendments to its cooking products test 

procedure for only conventional 

cooking products in today’s SNOPR. 

B. Standby Mode and Off Mode 

Section 310 of EISA 2007 amended 

EPCA to require DOE to amend the test 

procedures for covered products to 

address standby mode and off mode 

energy consumption. Specifically, the 

amendments require DOE to integrate 

standby mode and off mode energy 

consumption into the overall energy 

efficiency, energy consumption, or other 

energy descriptor for that product 

unless the current test procedures 

already fully account for such 

consumption. If integration is 

technically infeasible, DOE must 

prescribe a separate standby mode and 

off mode energy use test procedure, if 

technically feasible. (42 U.S.C. 

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

must consider the most current versions 

of IEC Standard 62301, ‘‘Household 

electrical appliances—Measurement of 

standby power,’’ and IEC Standard 

62087, ‘‘Methods of measurement for 

the power consumption of audio, video, 

and related equipment.’’ Id. 

C. The December 2010 NOPR 

On December 2, 2010, DOE published 

a NOPR (hereafter called the December 

2010 NOPR) in which it proposed to 

incorporate by reference into the test 

procedures for dishwashers, 

dehumidifiers, and conventional 

cooking products specific provisions 

from IEC Standard 62301 ‘‘Household 

electrical appliances—Measurement of 

standby power,’’ 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 75290, 

75295–97. DOE also proposed to 

incorporate into each test procedure 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. Id. at 75297–300. 

Further, DOE proposed to include in 

each test procedure additional language 

that would clarify the application of 

clauses from IEC Standard 62301 (First 

Edition) for measuring standby mode 

and off mode power consumption.7 Id. 

at 75300–04. DOE held a public meeting 

on December 17, 2010, to receive 

comments on the December 2010 NOPR, 

and accepted written comments, data, 

and information until February 15, 

2011. Commenters to the December 

2010 NOPR suggested that the draft 


Emcdonald on DSK5VPTVN1PROD with PROPOSALS2
Federal Register / Vol. 76, No. 182 / Tuesday, September 20, 2011 / Proposed Rules 58349 

updated version of IEC Standard 62301 

would provide practical improvement to 

the mode definitions and testing 

methodology for the test procedures that 

are the subject of this rulemaking. 

II. Summary of the Supplemental 

Notice of Proposed Rulemaking 

Based upon the public comment 

received on the December 2010 NOPR, 

DOE decided to further analyze the draft 

materials associated with IEC Standard 

62301 (Second Edition), which were in 

an advanced stage of development. 

Shortly thereafter, the IEC adopted and 

published IEC Standard 62301, 

‘‘Household electrical appliances— 

Measurement of standby power,’’ 

Edition 2.0 2011–01 (IEC Standard 

62301 (Second Edition) or ‘‘Second 

Edition’’) on January 27, 2011. 

Consistent with its statutory mandate, 

DOE has reviewed this latest version of 

the IEC standard and agrees that it does 

provide for improvement for 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 DOE 

test procedures for residential 

dishwashers, dehumidifiers, and 

conventional cooking products. Other 

than the specific amendments newly 

proposed in today’s SNOPR, DOE 

continues to propose the test procedure 

amendments originally included in the 

December 2010 NOPR. For the reader’s 

convenience, DOE has reproduced in 

this SNOPR the entire body of proposed 

regulatory text from the December 2010 

NOPR for the residential dishwasher, 

dehumidifier, and conventional cooking 

products test procedures, further 

amended as appropriate according to 

today’s proposals. DOE’s supporting 

analysis and discussion for the portions 

of the proposed regulatory text not 

affected by this SNOPR may be found in 

the December 2010 NOPR. 75 FR 75290 

(Dec. 2, 2010). 

III. Discussion 

A. Incorporation of IEC Standard 62301 

(Second Edition) 

As noted above, EPCA, as amended by 

EISA 2007, requires that test procedures 

be amended to include standby mode 

and off mode energy consumption, 

taking into consideration the most 

current versions of IEC Standards 62301 

and 62087. (42 U.S.C. 6295(gg)(2)(A)) 

The December 2010 NOPR proposed to 

incorporate in the test procedures for 

dishwashers, dehumidifiers, and 

conventional cooking products relevant 

provisions from IEC Standard 62301 

(First Edition) for measuring standby 

mode and off mode power. The 

amended test procedures would use 

these measured wattages in calculations 

to accomplish the incorporation of 

standby mode and off mode energy 

consumption into the test procedures. 

DOE reviewed the IEC Standard 62301 

(First Edition) and tentatively 

concluded that it would be generally 

applicable to dishwashers, 

dehumidifiers, and conventional 

cooking products, although some 

clarification would be needed. 

Specifically, DOE proposed in the 

December 2010 NOPR for standby mode 

and off mode power measurements to 

provide a stabilization period of at least 

30 minutes followed by an energy use 

measurement period of not less than 

10 minutes for each of the covered 

products. 75 FR 75290, 75300 (Dec. 2, 

2010). Additionally, for conventional 

cooking products, DOE proposed a 

specific standby mode power 

measurement methodology for units in 

which power varies as a function of 

displayed time. 75 FR 75290, 75302–04 

(Dec. 2, 2010). With these clarifications 

in place, the December 2010 NOPR 

proposed to reference IEC Standard 

62301 (First Edition) for the standby 

mode and off mode wattage 

measurements. (DOE notes that IEC 

Standard 62301 (First Edition) has been 

incorporated by reference in 10 CFR 

430.3, ‘‘Materials incorporated by 

reference,’’ as part of recent final 

amendments to the furnace and boiler 

test procedure. 75 FR 64621 (Oct. 20, 

2010).) 

DOE noted in the December 2010 

NOPR that there were expected to be 

significant differences between the first 

and second editions of IEC Standard 

62301, based upon DOE’s review of the 

Final Draft International Standard 

(FDIS) version available at that time. 

75 FR 75290, 75296 (Dec. 2, 2010). For 

example, IEC Standard 62301 (FDIS) 

modified certain provisions, such as 

clarifying the definition of ‘‘standby 

mode’’ and ‘‘off mode’’ to allow for the 

measurement of multiple standby power 

modes. 

As part of the December 2010 NOPR, 

DOE reviewed IEC Standard 62301 

(FDIS) and anticipated that, once 

finalized, it would ultimately define the 

various modes differently than IEC 

Standard 62301 (First Edition). 75 FR 

75290, 75296–97 (Dec. 2, 2010). IEC 

Standard 62301 (FDIS) incorporated 

responses to comments from multiple 

national committees from member 

countries on several previous draft 

versions, and thus, DOE believed, it 

provided the best available mode 

definitions. Although the revised IEC 

Standard 62301 (Second Edition) had 

not yet been officially released, DOE 

decided to consider the substance of the 

new operational mode definitions from 

the draft version IEC Standard 62301 

(FDIS) for the December 2010 NOPR. Id. 

DOE noted that the mode definitions in 

IEC Standard 62301 (FDIS) were 

substantively similar to those in the 

previous draft version (IEC Standard 

62301 Committee Draft for Vote (CDV)), 

which were the subject of extensive 

comments from interested parties 

during recent DOE test procedure 

rulemakings addressing standby mode 

and off mode energy use in other 

products (i.e., microwave ovens, clothes 

dryers, and room air conditioners). In 

those instances, interested parties 

indicated general support for adopting 

the mode definitions provided in IEC 

Standard 62301 (CDV). Due to the 

effective equivalence of the mode 

definitions in IEC Standard 62301 (CDV) 

and IEC Standard 62301 (FDIS), DOE 

stated in the December 2010 NOPR that 

the public comment support expressed 

for the mode definitions in IEC Standard 

62301 (CDV) would extend to those in 

IEC Standard 62301 (FDIS). 75 FR 

75290, 75297 (Dec. 2, 2010). 

After considering both versions of IEC 

Standard 62301 (i.e., First Edition and 

FDIS), DOE tentatively concluded in the 

December 2010 NOPR that the 

definitions of ‘‘standby mode,’’ ‘‘off 

mode,’’ and ‘‘active mode’’ provided in 

IEC Standard 62301 (FDIS) were the 

most useful, in that they expanded upon 

the EPCA mode definitions and 

provided additional guidance as to 

which functions would be associated 

with each mode. Therefore, DOE 

proposed definitions of ‘‘standby 

mode,’’ ‘‘off mode,’’ and ‘‘active mode’’ 

based on the definitions provided in IEC 

Standard 62301 (FDIS) in the December 

2010 NOPR. Id. 

DOE noted in the December 2010 

NOPR that other significant changes in 

the methodology of IEC Standard 62301 

were first introduced only at the FDIS 

stage. DOE noted that those changes had 

not been, at that time, the subject of 

significant public comment from 

interested parties, nor had DOE had the 

opportunity to conduct a thorough 

analysis of those provisions. 75 FR 

75290, 75297 (Dec. 2, 2010). 

Consequently, the merits of those latest 

changes had not been fully vetted, as 

would demonstrate that they would be 

preferable to the methodological 

provisions in IEC Standard 62301 (First 

Edition). Thus, DOE stated it was not 

able to determine whether the updated 

methodology represented the best 

available means to measure standby 

mode and off mode energy use. DOE,

in the docket of the residential dishwasher, 

dehumidifier, and conventional cooking products 

test procedures rulemaking; and (3) which appears 

on pages 27–30 and 36 of document number 10. 

10 DOE proposed in the December 2010 NOPR to 

define ‘‘active mode’’ for dishwashers, 

dehumidifiers, and conventional cooking products 

as ‘‘the condition in which the energy-using 

product is connected to a main power source, has 

been activated, and provides one or more main 

functions.’’ DOE proposed to define ‘‘inactive 

mode’’ for dishwashers, dehumidifiers, and 

conventional cooking products as ‘‘a standby mode 

that facilitates the activation of active mode by 

remote switch (including remote control), internal 

sensor, or timer, or that provides continuous status 

display.’’ DOE proposed to define ‘‘cycle finished 

mode’’ for dishwashers and conventional cooking 

products as ‘‘a mode which provides continuous 

status display following operation in active mode.’’ 

75 FR 75290, 75297–9 (Dec. 2, 2010). 

therefore, tentatively decided to base the 

proposed test procedure amendments 

(other than mode definitions) on the 

provisions of IEC Standard 62301 (First 

Edition). Id. (DOE notes that while the 

statute requires consideration of the 

latest version of IEC 62301, it does not 

require the agency to ignore other draft 

versions that have achieved an 

advanced level of vetting, such as IEC 

Standard 62301 (FDIS), which had 

already been out for a final vote among 

members.) 

In response to the December 2010 

NOPR, DOE received comments from 

interested parties regarding the 

appropriate version of IEC Standard 

62301 to use in its test procedures to 

measure standby mode and off mode 

energy use. Comments made at the 

public meeting were predicated upon 

IEC Standard 62301 (FDIS) being the 

most current, albeit draft, version of the 

updated standard. By the time the 

NOPR comment period ended on 

February 15, 2011, IEC Standard 62301 

(Second Edition) had published, and 

thus, interested parties were able to 

consider this version as the most current 

in their written submissions to DOE. 

Pacific Gas and Electric Company 

(PG&E), Southern California Gas 

Company, San Diego Gas and Electric, 

and Southern California Edison (jointly 

‘‘the California Utilities’’) supported 

harmonizing with the mode definitions 

in IEC Standard 62301 (FDIS). 

(California Utilities, No. 16 at p. 3; 

PG&E, No. 17 at p. 3) 8 The Association 

of Home Appliance Manufacturers 

(AHAM), Northwest Energy Efficiency 

Alliance (NEEA), and Whirlpool 

Corporation (Whirlpool) supported 

basing the methodology as well as mode 

definitions on the FDIS or Second 

Edition of IEC Standard 62301. (AHAM, 

Public Meeting Transcript, No. 10 at pp. 

27–30, 36 9; NEEA, No. 11 at pp. 1–2, 5– 

6; Whirlpool, No. 12 at pp. 1–2) AHAM 

and Whirlpool supported the use of IEC 

Standard 62301 (Second Edition) for 

reasons of: (1) international 

harmonization; (2) clarity and 

consistency in testing; and (3) reduced 

manufacturer test burden. (Whirlpool, 

No. 12 at pp. 1–2, AHAM, No. 14 at 

p. 3) 

AHAM noted that IEC Standard 62301 

(FDIS), and subsequently IEC Standard 

62301 (Second Edition), contain a 

number of important clarifications that 

were not present in IEC Standard 62301 

(First Edition) or IEC Standard 62301 

(CDV) and that would provide more 

accurate testing and measurement. 

Specifically, AHAM identified new or 

expanded sections on the measurement 

of power uncertainty, crest factor, power 

measurement frequency response, 

sampling methods, average reading 

methods for non-cyclic loads, and 

instrument measurement methods. 

AHAM opined that these provisions 

become critical in light of DOE’s 

announced intent to require third-party 

testing and verification testing of very 

small amounts of energy in standby 

mode. AHAM also commented that it 

would be difficult to pick and choose 

specific sections to adopt, because IEC 

Standard 62301 is intended to be read 

as a whole and that picking certain 

sections out may cause problems in how 

they are interpreted. For example, 

AHAM argued that picking out a 

definition from IEC Standard 62301 

(FDIS) and then combining that with 

incorporation by reference to IEC 

Standard 62301 (First Edition) would be 

inconsistent. (AHAM, No. 14 at p. 3; 

AHAM, Public Meeting Transcript, No. 

10 at pp. 27–30) 

NEEA stated that DOE has the 

regulatory flexibility to adjust mode 

definitions and test methods if it 

believes that a definition or procedure 

other than that in IEC Standard 62301 

would be more appropriate. On this 

point, NEEA argued that IEC Standard 

62301 (First Edition) is inadequate for 

comprehensively capturing the energy 

use of the broad array of products and 

modes that DOE is trying to cover. 

NEEA commented that IEC Standard 

62301 (FDIS) is particularly suitable for 

operational modes that have cyclic or 

unstable power consumption. NEEA 

commented that any measurement 

period that is 5 minutes or less, as 

allowed in IEC Standard 62301 (First 

Edition), is likely to be insufficient for 

capturing the energy use for these 

modes. However, NEEA also stated 

there could be certain specific modes for 

which the less complicated procedures 

from IEC Standard 62301 (First Edition) 

might be more suitable, specifically, if 

DOE includes cycle-finished mode as 

part of active mode rather than inactive 

(standby) mode.10 (NEEA, No. 11 at pp. 

1–2, 5–6) 

Because IEC Standard 62301 (Second 

Edition) was issued on January 27, 2011, 

it became the most current version 

under the EPCA requirements at the 

time DOE considered comments on the 

December 2010 NOPR. Accordingly, 

DOE then conducted a comparative 

review of the FDIS and Second Edition 

versions of IEC Standard 62301, and the 

results of this review demonstrated 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 agrees with the commenters 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. Specifically, section 4, 

paragraph 4.4 of the Second Edition 

revises the power measurement 

accuracy provisions that were present in 

the First Edition. A more 

comprehensive specification of required 

accuracy is provided in the Second 

Edition, which 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 to 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 0.1 for examples), 


Emcdonald on DSK5VPTVN1PROD with PROPOSALS2
Federal Register / Vol. 76, No. 182 / Tuesday, September 20, 2011 / Proposed Rules 58351 

so that sufficient accuracy of 

measurements is achieved under a full 

range of possible measured power levels 

without placing undue demands on the 

instrumentation. In addition, the 

wattage variations associated with the 

allowable uncertainty in power 

measurements are so small in relation to 

overall energy use that they would not 

result in measurable changes in the 

overall efficiency metric for 

dishwashers, dehumidifiers, or 

conventional cooking products. 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 commonlyused power measurement instruments 

were unable to meet the original 

requirements for certain types of loads. 

Therefore, DOE believes that the 

incremental testing burden associated 

with the additional measurements and 

calculations is offset by the more 

reasonable requirements for testing 

equipment, while maintaining 

measurement accuracy deemed 

acceptable and practical by voting 

members for IEC Standard 62301 

(Second Edition). For these reasons, 

DOE proposes in today’s supplemental 

notice to incorporate by 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 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. DOE is 

not aware of any dishwashers, 

dehumidifiers, or conventional cooking 

products with a recharging circuit. DOE 

also believes that a 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 

requirement for the determination, 

classification, and testing of all modes 

associated with every combination of 

available product configuration options 

(which may be more numerous than the 

modes associated with operation at the 

default settings) are not appropriate for 

the dishwasher, dehumidifier, and 

conventional cooking products test 

procedures. Accordingly, DOE is 

proposing qualifying language in the 

test procedure amendments for these 

products to disregard those portions of 

the installation instructions. 

The other major changes in the 

Second Edition that relate to the 

measurement of standby mode and off 

mode power consumption in covered 

products 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. According to 

the Second Edition, 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 December 2010 NOPR, which were 

based on IEC Standard 62301 (First 

Edition). 

In the December 2010 NOPR, DOE 

proposed for all covered products 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. Further, for any dishwasher or 

dehumidifier in which the power varies 

over a cycle, as described in section 5, 

paragraph 5.3.2 of the First Edition, the 

December 2010 NOPR proposed to 

require the use of the average power 

approach in section 5, paragraph 

5.3.2(a), with the same 30-minute 

minimum stabilization and 10-minute 

minimum measurement periods, as long 

as the measurement period comprises 

one or more complete cycles. 75 FR 

75290, 75300–01 (Dec. 2, 2010). DOE 

additionally proposed specific 

methodology for conventional cooking 

products in which power varies as a 

function of the time displayed. In that 

case, testers are allowed to choose 

measuring standby power by means of 

either: 

(a) 10-Minute Test 

(1) Allow the product to stabilize 

according to section 5, paragraph 5.3 of 

IEC Standard 62301 (First Edition), 

which requires a minimum of 5 

minutes; 

(2) Set the clock time to 3:23; 

(3) Allow another stabilization period 

until the clock time reaches 3:33; 

(4) Use the average power approach in 

section 5, paragraph 5.3.2(a) to measure 

standby mode power for a period of 10 

minutes +0/¥2 seconds; or 

(b) 12-Hour Test 

(1) At any clock time, allow the 

product to stabilize according to section 

5, paragraph 5.3 of IEC Standard 62301 

(First Edition), which requires a 

minimum of 5 minutes; 

(2) Use the average power approach in 

section 5, paragraph 5.3.2(a) to measure 

standby mode power for a period of 12 

hours +0/¥30 seconds. 

According to the proposal, 

manufacturers could elect to conduct 

either a 10-minute test or a 12-hour test, 

or both, and results of the 10-minute test 

that are within ± 2 percent of the results 

for the 12-hour test would be deemed to 


Emcdonald on DSK5VPTVN1PROD with PROPOSALS2
58352 Federal Register / Vol. 76, No. 182 / Tuesday, September 20, 2011 / Proposed Rules 

be representative of average energy use. 

Id. at 75302–04, 75328. 

For today’s supplemental notice, to 

determine the potential impacts of 

referencing methodology from IEC 

Standard 62301 (Second Edition) rather 

than from the First Edition, DOE 

compared the provisions allowed by 

each under different scenarios of power 

consumption stability. 

1. 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 December 

2010 NOPR, the total test time would be 

at minimum 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 an accumulated energy by 

the duration of the measurement period. 

In comparison, section 5, paragraph 

5.3.4 of IEC Standard 62301 (Second 

Edition) specifies a direct meter reading 

method that can be used for stable 

power consumption, 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 at minimum 

40 minutes. DOE agrees that this 

method likely improves the validity of 

the test results, as 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, 

increasing test time and complexity. 

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. 

DOE notes that 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. 

2. Unstable, Non-Cyclic Power 

Consumption 

Section 5, paragraph 5.3 from IEC 

Standard 62301 (First Edition), which 

DOE proposed in the December 2010 

NOPR to incorporate by reference with 

clarification, specifies that either an 

average power method or accumulated 

energy approach could be used for 

measuring non-cyclic unstable power 

consumption. As described previously, 

the clarifications proposed in the 

December 2010 NOPR would limit total 

test duration to 40 minutes. 

In contrast, the Second Edition 

requires the use of either a sampling 

method or average reading method for 

measuring power consumption in 

standby mode or off mode. The 

sampling method 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 average reading method in 

section 5, paragraph 5.3.3 IEC Standard 

62301 (Second Edition) comprises 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, 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 (potentially quite 

significantly), with a corresponding 

increase in manufacturer burden due to 

the additional time and complexity of 

the test conduct. 

3. Cyclic Power Consumption 

Dishwashers and Dehumidifiers 

As noted previously, DOE proposed 

in the December 2010 NOPR for these 

products 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 


Emcdonald on DSK5VPTVN1PROD with PROPOSALS2
Federal Register / Vol. 76, No. 182 / Tuesday, September 20, 2011 / Proposed Rules 58353 

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 extend 

significantly longer, again potentially 

introducing issues of increased test 

burden. 

Conventional Cooking Products 

For conventional cooking products in 

which standby mode power 

consumption varies as a function of 

displayed time, DOE proposed in the 

December 2010 NOPR to require the use 

of either the 10-minute or 12-hour test 

methodology described previously, 

based on the average power approach of 

section 5, paragraph 5.3.2(a) of IEC 

Standard 62301 (First Edition). If the 

results of the 10-minute test agree to 

within ±2 percent with the results of the 

12-hour test, the 10-minute test results 

would be deemed representative and 

would require a minimum of 25 minutes 

to conduct. If a full 12-hour test is used, 

total test duration would be 12 hours 

and 5 minutes. 

Under the Second Edition, testers 

would be required to use the sampling 

method of section 5, paragraph 5.3.2 for 

conventional cooking products that 

consume varying power as a function of 

the displayed time due to the cyclic 

nature of this power consumption. 

Because all of the clock displays which 

DOE observed to be incorporated in 

conventional cooking products are 

based on a 12-hour cycle, such a 

product which consumes varying power 

as a function of the displayed time 

would be required under the Second 

Edition to be tested for a minimum of 

4 cycles, or 48 hours, in addition to an 

initial stabilization period of not less 

than 10 minutes. DOE notes that this 

test duration would impose a greatly 

increased test burden on manufacturers, 

particularly in comparison to the 

previously proposed 10-minute 

methodology. 

4. Conclusions on Test Methodology 

DOE, in evaluating IEC Standard 

62301 (Second Edition) in comparison 

to the First Edition, confers substantial 

weight to 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 test methods specified in the 

Second Edition. However, DOE believes 

that in most cases, this added burden on 

manufacturers has been sufficiently 

considered by the IEC voting members 

as being outweighed by the improved 

accuracy and representativeness of the 

resulting power consumption 

measurement. Furthermore, 

manufacturers were aware of these 

differences, but nevertheless, they 

overwhelmingly expressed support for 

DOE’s use of the Second Edition. In 

particular, DOE tentatively concludes 

that the application of the provisions of 

the Second Edition to all power 

measurements in standby mode and off 

mode for dishwashers and 

dehumidifiers would be appropriate, 

and is proposing incorporation by 

reference of the relevant paragraphs of 

section 5.3 of IEC Standard 62301 

(Second Edition) in the test procedures 

for these products. 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 IEC preferred 

sampling method provides for a test 

duration that is approximately the same 

or shorter than the allowable IEC 

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. By monitoring the variation in 

power consumption during the test, the 

test operator could determine whether it 

is stable or unstable, and, thus, the 

required duration of the sampling 

periods. For cyclic power consumption, 

the Second Edition requires the use of 

the sampling method. Thus, DOE 

proposes in today’s SNOPR to specify 

the use of the sampling method in 

section 5.3.2 of IEC Standard 62301 

(Second Edition) for all measures of 

standby mode and off mode power 

consumption for residential 

dishwashers and dehumidifiers. 

Similarly, for conventional cooking 

products, DOE has tentatively 

concluded that section 5.3 of the Second 

Edition includes provisions that are 

appropriate for measuring off mode and 

standby modes (except in the case of a 

unit’s clock whose power consumption 

varies by the time displayed), and that 

the sampling method in section 5.3.2 of 

the Second Edition would also provide 

for measurements with minimal test 

burden. Thus, DOE proposes for 

conventional cooking products to 

require the use of the sampling method 

in section 5.3.2 of the Second Edition, 

except as follows. In the narrow case of 

cooking products with power 

consumption that varies as a function of 

the time displayed, DOE tentatively 

concludes that the application of the 

test methodology from the Second 

Edition would cause manufacturers to 

incur significant burden that would not 

be warranted by any potential improved 

accuracy of the test measurement. For 

this reason, DOE continues to propose 

in this supplemental notice the 10- 

minute and 12-hour test methods for 

these products in the conventional 

cooking products test procedure. 

Because DOE proposes to base the other 

provisions incorporated by reference 

from IEC Standard 62301 on the Second 

Edition, DOE has revised its proposal 

regarding the 10-minute and 12-hour 

tests to include language equivalent to 

the average power method from the First 

Edition, without incorporating the First 

Edition by reference. 

To this end, this supplemental notice 

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 supplemental 

notice incorporate provisions from it. In 

addition, there are a number of editorial 

changes necessary in the various 

appendices addressed in today’s 

supplemental notice to allow for the 

correct referencing to the Second 

Edition. For example, the definition 

sections need to define the IEC Standard 

62301 as the Second Edition instead of 

the First Edition. Also, there are some 

section numbering differences in the 

Second Edition which impact the text of 

the measurement provisions of the 

relevant test procedures. 

DOE further notes that the proposed 

amendments to the cooking products 

test procedure would retain the 

references to certain provisions of IEC 

Standard 62301 (First Edition) which 

were adopted in the March 2011 Interim 

Final Rule for the purposes of 

measuring standby mode and off mode 

energy use in microwave ovens. As 

discussed above, the March 2011 

Interim Final Rule invited comments on 

the merits of adopting additional 

provisions of IEC Standard 62301 

(Second Edition) in the microwave oven 

test procedure (76 FR 12825, 12833 

(March 9, 2011)), but at this time, DOE 

has not revised its microwave oven test 

procedure accordingly. Because today’s 

supplemental notice addresses such 


Emcdonald on DSK5VPTVN1PROD with PROPOSALS2
58354 Federal Register / Vol. 76, No. 182 / Tuesday, September 20, 2011 / Proposed Rules 

energy use for conventional cooking 

products but not microwave ovens, DOE 

is not proposing to remove or amend the 

references to the First Edition in the 

cooking products test procedure, which 

contains both types of products, other 

than to clarify that the First Edition is 

being referenced for microwave ovens 

rather than the Second Edition. DOE’s 

proposal for conventional cooking 

products, based on relevant sections of 

IEC Standard 62301 (Second Edition) 

would neither be affected by, nor 

impact, the testing procedures for 

microwave ovens other than section 

renumbering as appropriate. 

B. Technical Corrections 

Due to a transcription error in 

publication, the December 2010 NOPR 

erroneously specified certain dates in 

the regulatory text for the proposed test 

procedure amendments. Specifically, 

the December 2010 NOPR indicated that 

representations as to energy use in 

standby mode and off mode for 

dishwashers, conventional cooking 

products, and dehumidifiers made after 

May 31, 2011, would have to be based 

upon the proposed amended 

dishwasher test procedure in 10 CFR 

part 430, subpart B, appendix C, the 

amended conventional cooking 

products test procedure in appendix I, 

and the amended dehumidifier test 

procedure in appendix X. 75 FR 75290, 

75324, 75326, 75333 (Dec. 2, 2010). 

Similarly, the compliance date was 

erroneously specified in the December 

2010 NOPR as May 31, 2011, in the 

calculations of dishwasher estimated 

annual operating cost and estimated 

annual energy use that incorporate 

measures of standby mode and off mode 

energy use, as proposed for the test 

procedures in 10 CFR 430.23(c). 75 FR 

75290, 75321–22 (Dec. 2, 2010). In each 

of these instances, the December 2010 

NOPR should have specified the date as 

‘‘180 days after date of publication of 

the test procedure final rule in the 

Federal Register.’’ DOE is proposing to 

make this correction to the dates in 

today’s SNOPR, and clarifies that 

manufacturers would not be subject to 

a May 31, 2011, deadline for any of the 

products as part of this rulemaking. 

C. Compliance With Other EPCA 

Requirements 

1. Test Burden 

EPCA requires that ‘‘[a]ny test 

procedures prescribed or amended 

under this section shall be reasonably 

designed to produce test results which 

measure energy efficiency, energy use 

* * * or estimated annual operating 

cost of a covered product during a 

representative average use cycle or 

period of use * * * and shall not be 

unduly burdensome to conduct.’’ (42 

U.S.C. 6293(b)(3)) 

In the December 2010 NOPR, DOE 

noted that the proposed amendments to 

the residential dishwasher, 

dehumidifier, and conventional cooking 

products test procedures 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 

dishwashers, dehumidifiers, and 

conventional cooking products test 

procedures 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 tests. 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 December 

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 75290, 

75316 (Dec. 2, 2010). 

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), which has been the 

subject of significant review and input 

from interested parties and, thus, 

continues to be an internationally 

accepted test standard for measuring 

standby mode and off mode power 

consumption. As discussed in section 0 

of this notice, DOE believes that the 

provisions of IEC Standard 62301 

(Second Edition) that it proposes to 

incorporate by reference through 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 tentatively 

concludes that today’s supplemental 

proposed amendments would also 

provide measurements representative of 

average consumer use of the product 

under test, even if the test conditions 

and procedures may not be identical to 

average consumer use (for example, 

specified display times). DOE further 

believes these new provisions in the 

applicable sections of IEC Standard 

62301 (Second Edition) improve test 

results without undue testing burden. 

DOE acknowledges that certain methods 

from IEC Standard 62301 (Second 

Edition) may increase test duration 

somewhat, but where such an increase 

was deemed excessive (i.e., for products 

with clocks that can vary in power 

consumption as a function of time 

displayed), DOE retained the method 

previously proposed in order to mitigate 

test burden. DOE also believes that the 

potential for increased test burden in 

other power consumption 

measurements is offset by more 

reasonable requirements for testing 

equipment, while maintaining 

measurement accuracy deemed 

acceptable and practical by voting 

members for IEC Standard 62301 

(Second Edition). 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. 

2. Potential Incorporation of IEC 

Standard 62087 

Under 42 U.S.C. 6295(gg)(2)(A), EPCA 

directs DOE to consider IEC Standard 

62087 when amending test procedures 

to include standby mode and off mode 

power measurements. For the December 

2010 NOPR, DOE reviewed IEC 

Standard 62087, ‘‘Methods of 

measurement for the power 

consumption of audio, video, and 

related equipment’’ (Second Edition 

2008–09), and tentatively determined 

that it would not be applicable to 

measuring power consumption of 

electrical appliances such as 

dishwashers, dehumidifiers, and 

conventional cooking products. 

Therefore, DOE tentatively concluded 

that referencing IEC Standard 62087 is 

not necessary for the proposed 

amendments to the test procedures that 

are the subject of this rulemaking. 75 FR 

75290, 75316 (Dec. 2, 2010). For the 

same reason, DOE maintains the same 

tentative conclusion for today’s SNOPR.

Federal Register / Vol. 76, No. 182 / Tuesday, September 20, 2011 / Proposed Rules 58355 

3. Integration of Standby Mode and Off 

Mode Energy Consumption Into the 

Efficiency Metrics 

Under 42 U.S.C. 6295(gg)(2)(A), 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 such an integrated 

test procedure is technically infeasible. 

As noted in the December 2010 NOPR, 

DOE proposed to incorporate such 

energy consumption into existing 

metrics (‘‘estimated annual energy use’’ 

and ‘‘estimated annual operating cost’’ 

for dishwashers and ‘‘estimated annual 

operating cost’’ for conventional 

cooking products) and into new metrics 

(‘‘integrated energy factor’’ (IEF) for 

dehumidifiers and IEF and ‘‘integrated 

annual energy consumption’’ for 

conventional cooking products). 75 FR 

75290, 75316 (Dec. 2, 2010). 

EPCA further provides that test 

procedure amendments adopted to 

comply with the new statutory 

requirements for standby mode and off 

mode energy consumption shall not be 

used to determine compliance with 

previously established energy 

conservation standards. (42 U.S.C. 

6295(gg)(2)(C)) Under this provision, 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 impact on, 

existing energy conservation standards 

(although representations as to standby 

mode and off mode energy use for 

dishwashers, dehumidifiers, and 

conventional cooking products made 

later than 180 days after the date of 

publication of the final rule in this 

rulemaking would be required to be 

based upon results generated under the 

amended test procedures). 

Even though 42 U.S.C. 6295(gg)(2)(C) 

clearly states that the test procedure 

amendments for measurement of 

standby mode and off mode energy 

consumption shall not apply in terms of 

compliance with existing energy 

conservation standards, DOE must 

nonetheless determine the effect of such 

test procedure amendments on 

measured energy efficiency, measured 

energy use, or measured water use of 

any covered product, pursuant to 42 

U.S.C. 6293(e)(1). DOE provided 

analysis in the December 2010 NOPR 

which determined that the proposed 

amendments would not measurably 

alter the existing energy efficiency and 

energy use metrics for residential 

dishwashers, dehumidifiers, and 

conventional cooking products. In 

addition, those proposed amendments 

in each test procedure would clarify that 

manufacturers would not be required to 

use the provisions relating to standby 

mode and off mode energy use until the 

compliance date of new energy 

conservation standards addressing such 

energy use for the relevant product. 

Thus, no amendments to the energy 

conservation standards would be 

required pursuant to 42 U.S.C. 

6293(e)(2), because such test procedure 

amendments would not impact the 

existing energy conservation standards 

until the compliance date of a 

subsequent final rule that amends the 

standard to comprehensively address 

standby mode and off mode energy 

consumption. 75 FR 75290, 75316–17 

(Dec. 2, 2010). 

Because DOE’s proposed amendments 

in today’s SNOPR: (1) Would not 

produce measurably different 

evaluations of standby mode and off 

mode energy use through the use of 

provisions from IEC Standard 62301 

(Second Edition) in place of those from 

IEC Standard 62301 (First Edition); (2) 

would not alter the approaches for 

integrating standby mode and off mode 

energy use into the energy efficiency 

and energy use metrics; and (3) would 

retain the clarifications regarding test 

procedure and energy conservation 

standards compliance dates, DOE 

tentatively concludes that the 

supplemental proposed amendments 

would also comply with the EPCA 

requirements under 42 U.S.C. 6293(e)(2) 

and 6295(gg)(2)(A) and (C). 

4. Certification Requirements 

As codified at 42 U.S.C. 6299–6305 

and 6316, EPCA authorizes DOE to 

enforce compliance with the energy and 

water conservation standards 

established for certain consumer 

products and industrial/commercial 

equipment. (42 U.S.C. 6299–6305 

(consumer products), 6316 (industrial 

equipment)) On March 7, 2011, the 

Department published a final rule in the 

Federal Register, which revised, 

consolidated, and streamlined its 

existing certification, compliance, and 

enforcement regulations for certain 

consumer products and industrial/ 

commercial equipment covered under 

EPCA, including dishwashers, 

dehumidifiers, and conventional 

cooking products. 76 FR 12422. The 

certification regulations are codified at 

10 CFR 429.19 (dishwashers), 10 CFR 

429.23 (conventional cooking tops, 

conventional ovens, microwave ovens), 

and 10 CFR 429.36 (dehumidifiers). 

The certification requirements for 

each of the products covered in today’s 

SNOPR consist of a sampling plan for 

selection of units for testing and 

requirements for certification reports. 

Because the proposed amendments to 

the residential dishwasher, 

dehumidifier, and conventional cooking 

products test procedures 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 

a new metric (IEF) for both conventional 

cooking products and dehumidifiers, 

DOE additionally proposes amended 

provisions in the sampling plan at 10 

CFR 429.23 and 10 CFR 429.36 that 

would include IEF along with the 

existing measure of EF. No such 

amendments are proposed for 

residential dishwashers, because DOE is 

not proposing any new energy efficiency 

metric for these products. 

IV. Procedural Issues and Regulatory 

Review 

DOE has concluded that the 

determinations made pursuant to the 

various procedural requirements 

applicable to the December 2010 NOPR 

remain unchanged for this SNOPR. 

These determinations are set forth in the 

December 2010 NOPR. 75 FR 75290, 

75317–19 (Dec. 2, 2010). DOE 

acknowledges that certain provisions of 

IEC Standard 62301 (Second Edition) 

that are proposed to be incorporated by 

reference have the potential for 

somewhat greater test time as compared 

to the provisions from IEC Standard 

62301 (First Edition), and, therefore, 

DOE gave particular consideration to its 

review under the Regulatory Flexibility 

Act (5 U.S.C. 601 et seq.). DOE believes 

that the proposed amendments in 

today’s SNOPR would still result in a 

duration of standby mode and off mode 

testing that is generally not expected to 

exceed the time required to conduct 

current energy testing. DOE further 

believes that the newly proposed 

revisions would not alter the costs it 

estimated for standby mode and off 

mode testing in the December 2010 

NOPR. Thus, DOE continues to 

tentatively conclude and certify that the 

proposed rule would not have a 

significant economic impact on a 

substantial number of small entities. 

Accordingly, DOE has not prepared a 

regulatory flexibility analysis for this 

rulemaking. DOE will transmit the 

certification and supporting statement 

of factual basis to the Chief Counsel for 

Advocacy of the SBA for review under 

5 U.S.C. 605(b).

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 comments are welcome on 

all aspects of this rulemaking, DOE is 

particularly interested in receiving 

comments and views of interested 

parties on the following issues: 

1. Incorporation of IEC Standard 

62301 (Second Edition). DOE invites 

comment on the adequacy of IEC 

Standard 62301 (Second Edition) to 

measure standby mode and off mode 

power consumption for residential 

dishwashers, dehumidifiers, and 

conventional cooking products, and the 

suitability of incorporating into DOE 

regulations the following specific 

provisions from IEC Standard 62301 

(Second Edition): section 4 (‘‘General 

conditions for measurements’’), 

paragraph 4.2, ‘‘Test room,’’ paragraph 

4.3.2, ‘‘Supply voltage waveform,’’ and 

paragraph 4.4, ‘‘Power measuring 

instruments,’’ and section 5 

(‘‘Measurements’’), paragraph 5.1, 

‘‘General,’’ paragraph 5.2 ‘‘Preparation 

of product’’, and paragraph 5.3.2, 

‘‘Sampling method.’’ (See section 0) 

2. Methods Based on IEC Standard 

62301 (First Edition) for Conventional 

Cooking Products with Clocks. DOE 

welcomes comment on its 

determination that the provisions of IEC 

Standard 62301 (Second Edition) would 

cause manufacturers to incur significant 

test burden for conventional cooking 

products with power consumption that 

varies as a function of the time 

displayed, and the continued proposal 

of 10-minute and 12-hour test methods 

of measuring standby mode power for 

these products in the conventional 

cooking products test procedure. (See 

section 0)

of publication of the test procedure final rule 

in the Federal Register) must be based 

upon results generated under this test 

procedure using sections 4.5, 4.5.1 through 

4.5.3, and 5.7 and disregarding sections 4.4 

and 5.6 of this Appendix, consistent with the 

requirements of 42 U.S.C. 6293(c)(2). After 

July 1, 2010, any adopted energy 

conservation standard shall incorporate 

standby mode and off mode energy 

consumption, and upon the compliance date 

for such standards, compliance with the 

applicable provisions of this test procedure 

will also be required.

2.9 Testing requirements. Provisions in 

this Appendix pertaining to dishwashers that 

operate with a nominal inlet temperature of 

50 °F or 120 °F apply only to water-heating 

dishwashers as defined in section 1.25 of this 

Appendix. 

2.10 Preconditioning requirements. 

Precondition the dishwasher by establishing 

the testing conditions set forth in sections 2.1 

through 2.5 of this Appendix. Set the 

dishwasher to the preconditioning cycle as 

defined in section 1.13 of this Appendix, 

without using a test load, and initiate the 

cycle. 

3. Instrumentation 

* * * * * 

3.8 Standby mode and off mode watt 

meter. The watt meter used to measure 

standby mode and off mode power 

consumption shall meet the requirements 

specified in Section 4, Paragraph 4.4 of IEC 

62301 (incorporated by reference, see 

§ 430.3). 

4. Test Cycle and Measurements 

* * * * * 

4.4 Simplified standby mode power. 

Connect the dishwasher to a standby 

wattmeter or a standby watt-hour meter as 

specified in sections 3.6 and 3.7, 

respectively, of this Appendix. Select the 

conditions necessary to achieve operation in 

the simplified standby mode as defined in 

section 1.17 of this Appendix. Monitor the 

power consumption but allow the 

dishwasher to stabilize for at least 5 minutes. 

Then monitor the power consumption for at 

least an additional 5 minutes. If the power 

level does not change by more than 5 percent 

from the maximum observed value during 

the later 5 minutes and if there is no cyclic 

or pulsing behavior of the load, the load can 

be considered stable. For stable operation, 

simplified standby mode power, Sm, can be 

recorded directly from the standby watt 

meter in watts or accumulated using the 

standby watt-hour meter over a period of at 

least 5 minutes. For unstable operation, the 

energy must be accumulated using the 

standby watt-hour meter over a period of at 

least 5 minutes and must capture the energy 

use over one or more complete cycles. 

Calculate the average simplified standby 

mode power, Sm, expressed in watts by 

dividing the accumulated energy 

consumption by the duration of the 

measurement period. 

4.5 Standby mode and off mode power. 

Connect the dishwasher to a standby mode 

and off mode watt meter as specified in 


Emcdonald on DSK5VPTVN1PROD with PROPOSALS2
58362 Federal Register / Vol. 76, No. 182 / Tuesday, September 20, 2011 / Proposed Rules 

section 3.8 of this Appendix. Establish the 

testing conditions set forth in sections 2.1, 

2.2, and 2.5.2 of this Appendix. For 

dishwashers that take some time to enter a 

stable state from a higher power state as 

discussed in Section 5, Paragraph 5.1, note 1 

of IEC 62301 (incorporated by reference; see 

§ 430.3), allow sufficient time for the 

dishwasher to reach the lower power state 

before proceeding with the test measurement. 

Follow the test procedure specified in 

Section 5, Paragraph 5.3.2 of IEC 62301 for 

testing in each possible mode as described in 

sections 4.5.1 through 4.5.3 of this Appendix. 

4.5.1 If the dishwasher has an inactive 

mode, as defined in section 1.8 of this 

Appendix, measure and record the average 

inactive mode power of the dishwasher, PIA, 

in watts. 

4.5.2 If the dishwasher has an off mode, 

as defined in section 1.11 of this Appendix, 

measure and record the average off mode 

power, POM, in watts. 

4.5.3 If the dishwasher has a cycle 

finished mode, as defined in section 1.5 of 

this Appendix, measure and record the 

average cycle finished mode power, PCF, in 

watts. 

5. Calculation of Derived Results From Test 

Measurements 

* * * * * 

5.6 Annual simplified standby energy 

consumption. Calculate the estimated annual 

simplified standby energy consumption. First 

determine the number of standby hours per 

year, Hs, defined as: 

Hs = H ¥ (N × L) 

Where: 

H = the total number of hours per year = 8766 

hours per year, 

N = the representative average dishwasher 

use of 215 cycles per year, 

L = the average of the duration of the normal 

cycle and truncated normal cycle, for 

non-soil-sensing dishwashers with a 

truncated normal cycle; the duration of 

the normal cycle, for non-soil-sensing 

dishwashers without a truncated normal 

cycle; the average duration of the sensor 

light response, truncated sensor light 

response, sensor medium response, 

truncated sensor medium response, 

sensor heavy response, and truncated 

sensor heavy response, for soil-sensing 

dishwashers with a truncated cycle 

option; the average duration of the 

sensor light response, sensor medium 

response, and sensor heavy response, for 

soil-sensing dishwashers without a 

truncated cycle option. 

Then calculate the estimated annual 

simplified standby power use, S, expressed 

in kilowatt-hours per year and defined as: 

S = Sm × ((Hs)/1000) 

Where: 

Sm = the simplified standby mode power in 

watts as determined in section 4.4 of this 

Appendix. 

5.7 Annual standby mode and off mode 

energy consumption. Calculate the standby 

mode and off mode annual energy 

consumption for dishwashers, ETSO, 

expressed in kilowatt-hours per year, 

according to the following: 

ETSO = [(PIA × SIA) + (POM × SOM) + (PCF × 

SCF)] × K 

Where: 

PIA= dishwasher inactive mode power, in 

watts, as measured in section 4.5.1 of 

this Appendix. 

POM = dishwasher off mode power, in watts, 

as measured in section 4.5.2 of this 

Appendix. 

PCF = dishwasher cycle finished mode power, 

in watts, as measured in section 4.5.3 of 

this Appendix. 

If the dishwasher has both inactive mode 

and off mode, SIA and SOM both equal STOT/ 

2; 

STOT equals the total number of inactive 

mode and off mode hours per year, defined 

as: 

If the dishwasher has cycle finished mode, 

STOT, in hours, equals HTSO ¥ SCF; 

If the dishwasher does not have cycle 

finished mode, STOT equals HTSO; 

HTSO equals the total number of standby 

mode and off mode hours per year, defined 

as: 

HTSO = H ¥ (N × L) 

Where: 

H = the total number of hours per year = 8766 

hours per year, 

N = the representative average dishwasher 

use of 215 cycles per year, 

L = the average of the duration of the normal 

cycle and truncated normal cycle, for 

non-soil-sensing dishwashers with a 

truncated normal cycle; the duration of 

the normal cycle, for non-soil-sensing 

dishwashers without a truncated normal 

cycle; the average duration of the sensor 

light response, truncated sensor light 

response, sensor medium response, 

truncated sensor medium response, 

sensor heavy response, and truncated 

sensor heavy response, for soil-sensing 

dishwashers with a truncated cycle 

option; the average duration of the 

sensor light response, sensor medium 

response, and sensor heavy response, for 

soil-sensing dishwashers without a 

truncated cycle option; 

If the dishwasher has an inactive mode but 

no off mode, the inactive mode annual hours, 

SIA, is equal to STOT, and the off mode annual 

hours, SOM, is equal to 0; 

If the dishwasher has an off mode but no 

inactive mode, SIA is equal to 0, and SOM is 

equal to STOT; 

SCF = 237, dishwasher cycle finished mode 

annual hours; 

K = 0.001 kWh/Wh conversion factor for 

watt-hours to kilowatt-hours.

Appendix I to Subpart B of Part 430— 

Uniform Test Method for Measuring the 

Energy Consumption of Conventional 

Ranges, Conventional Cooking Tops, 

Conventional Ovens, and Microwave 

Ovens 

Note: The procedures and calculations in 

this Appendix I need not be performed to 

determine compliance with energy 

conservation standards for conventional 

ranges, conventional cooking tops, 

conventional ovens, and microwave ovens at 

this time. However, any representation 

related to standby mode and off mode energy 

consumption of conventional ranges, 

conventional cooking tops, and conventional 

ovens made after (date 180 days after date of 

publication of the test procedure final rule in 

the Federal Register) and of microwave 

ovens made after September 6, 2011 must be

Federal Register / Vol. 76, No. 182 / Tuesday, September 20, 2011 / Proposed Rules 58363 

based upon results generated under this test 

procedure, consistent with the requirements 

of 42 U.S.C. 6293(c)(2). After July 1, 2010, 

however, when DOE adopts an energy 

conservation standard that incorporates 

standby mode and off mode energy 

consumption, and upon the compliance date 

for such standards, compliance with the 

applicable provisions of this test procedure 

will also be required. Future revisions may 

add relevant provisions for measuring active 

mode in microwave ovens.

the same basic model of the appliance would 

attain if it remained in the test room for 24 

hours while not operating with all oven 

doors closed and with any gas pilot lights on 

and adjusted in accordance with 

manufacturer’s instructions. 

1.11 Off mode means a mode in which 

the product is connected to a mains power 

source and is not providing any active mode 

or standby mode function, and where the 

mode may persist for an indefinite time. An 

indicator that only shows the user that the 

product is in the off position is included 

within the classification of an off mode. 

1.12 Primary energy consumption means 

either the electrical energy consumption of a 

conventional electric oven or the gas energy 

consumption of a conventional gas oven.

that quantity of gas that occupies 1 cubic foot 

(L) when saturated with water vapor at a 

temperature of 60 °F (15.6 °C) and a pressure 

of 30 inches of mercury (101.6 kPa) (density 

of mercury equals 13.595 grams per cubic 

centimeter). 

1.15 Standby mode means any modes 

where the product is connected to a mains 

power source and offers one or more of the 

following user-oriented or protective 

functions which may persist for an indefinite 

time: (a) to facilitate the activation of other 

modes (including activation or deactivation 

of active mode) by remote switch (including 

remote control), internal sensor, or timer; (b) 

continuous functions, including information 

or status displays (including clocks) or 

sensor-based functions. A timer is a 

continuous clock function (which may or 

may not be associated with a display) that 

provides regular scheduled tasks (e.g., 

switching) and that operates on a continuous 

basis.

3. Test Methods and Measurements 

* * * * * 

3.1.1 Conventional oven. Perform a test 

by establishing the testing conditions set 

forth in section 2, Test Conditions, of this 

Appendix, and adjust any pilot lights of a 

conventional gas oven in accordance with the 

manufacturer’s instructions and turn off the 

gas flow to the conventional cooking top, if 

so equipped. Before beginning the test, the 

conventional oven shall be at its normal 

nonoperating temperature as defined in 

section 1.10 and described in section 2.6. Set 

the conventional oven test block W1

approximately in the center of the usable 

baking space. If there is a selector switch for 

selecting the mode of operation of the oven, 

set it for normal baking. If an oven permits 

baking by either forced convection by using 

a fan, or without forced convection, the oven 

is to be tested in each of those two modes. 

The oven shall remain on for at least one 

complete thermostat ‘‘cut-off/cut-on’’ of the 

electrical resistance heaters or gas burners 

after the test block temperature has increased 

234 °F (130 °C) above its initial temperature. 

3.1.1.1 Self-cleaning operation of a 

conventional oven. Establish the test 

conditions set forth in Section 2, Test 

Conditions, of this Appendix. Adjust any 

pilot lights of a conventional gas oven in 

accordance with the manufacturer’s 

instructions and turn off the gas flow to the 

conventional cooking top. The temperature of 

the conventional oven shall be its normal 

nonoperating temperature as defined in 

section 1.10 and described in section 2.6. 

Then set the conventional oven’s selfcleaning process in accordance with the 

manufacturer’s instructions. If the selfcleaning process is adjustable, use the 

average time recommended by the 

manufacturer for a moderately soiled oven. 

* * * * * 

3.1.1.3 Conventional oven standby mode 

and off mode power. Establish the standby 

mode and off mode testing conditions set 

forth in Section 2, Test Conditions, of this 

Appendix. For conventional ovens that take

higher power state as discussed in Section 5, 

Paragraph 5.1, Note 1 of IEC 62301 (Second 

Edition) (incorporated by reference; see 

§ 430.3), allow sufficient time for the 

conventional oven to reach the lower power 

state before proceeding with the test 

measurement. Follow the test procedure as 

specified in Section 5, Paragraph 5.3.2 of IEC 

62301 (Second Edition) for testing in each 

possible mode as described in 3.1.1.3.1 

through 3.1.1.3.3. For units in which power 

varies as a function of displayed time in 

standby mode, either: (1) set the clock time 

to 3:23 at the end of the stabilization period 

specified in Section 5, Paragraph 5.3 of IEC 

62301 (First Edition), and use the average 

power approach described in Section 5, 

Paragraph 5.3.2(a) of IEC 62301 (First 

Edition), but with a single test period of 10 

minutes +0/¥2 sec after an additional 

stabilization period until the clock time 

reaches 3:33; or (2) at any starting clock time, 

allow a stabilization period as described in 

Section 5, Paragraph 5.3 of IEC 62301 (First 

Edition), and use the average power approach 

described in Section 5, Paragraph 5.3.2(a) of 

IEC 62301 (First Edition), but with a single 

test period of 12 hours +0/¥30 sec. Testing 

may be conducted using either a 12-hour test, 

a 10-minute test, or both tests; however, if a 

manufacturer elects to perform both tests on 

a unit, the manufacturer may only use the 

results from one of the tests (i.e., the 12-hour 

test or the 10-minute test) as the test results 

for that unit. Results of the 10-minute test 

that are within ±2 percent of the 12-hour test 

are deemed to be representative of average 

energy use. 

3.1.1.3.1 If the conventional oven has an 

inactive mode, as defined in section 1.9, 

measure and record the average inactive 

mode power of the conventional oven, PIA, in

temperature of the conventional cooking top 

shall be its normal nonoperating temperature 

as defined in section 1.10 and described in 

section 2.6. Set the test block in the center 

of the surface unit under test. The small test 

block, W2, shall be used on electric surface 

units of 7 inches (178 mm) or less in 

diameter. The large test block, W3, shall be 

used on electric surface units over 7 inches 

(178 mm) in diameter and on all gas surface 

units. Turn on the surface unit under test and 

set its energy input rate to the maximum 

setting. When the test block reaches 144 °F 

(80 °C) above its initial test block 

temperature, immediately reduce the energy 

input rate to 25±5 percent of the maximum 

energy input rate. After 15±0.1 minutes at the 

reduced energy setting, turn off the surface 

unit under test.

the stabilization period specified in Section 

5, Paragraph 5.3 of IEC 62301 (First Edition), 

and use the average power approach 

described in Section 5, Paragraph 5.3.2(a) of 

IEC 62301 (First Edition), but with a single 

test period of 10 minutes +0/¥2 sec after an 

additional stabilization period until the clock 

time reaches 3:33; or (2) at any starting clock 

time, allow a stabilization period as 

described in Section 5, Paragraph 5.3 of IEC 

62301 (First Edition), and use the average 

power approach described in Section 5, 

Paragraph 5.3.2(a) of IEC 62301 (First

following series of measurements: Measure 

the block temperature, TA, and the energy 

consumed, EA, or volume of gas consumed, 

VA, at the end of the last ‘‘ON’’ period of the 

conventional oven before the block reaches 

TO. Measure the block temperature, TB, and

temperature, TI). If the conventional oven 

permits baking by either forced convection or 

without forced convection and the oven 

thermostat operates by cycling on and off, 

make the following series of measurements 

with and without the forced convection 

mode: Measure the block temperature, TA, 

and the energy consumed, EA, or volume of 

gas consumed, VA, at the end of the last 

‘‘ON’’ period of the conventional oven before 

the block reaches TO. Measure the block 

temperature, TB, and the energy consumed, 

EB, or volume of gas consumed, VB, at the 

beginning of the next ‘‘ON’’ period. Measure 

the block temperature, TC, and the energy 

consumed, EC, or volume of gas consumed, 

VC, at the end of that ‘‘ON’’ period. Measure 

the block temperature, TD, and the energy 

consumed, ED, or volume of gas consumed, 

VD, at the beginning of the following ‘‘ON’’ 

period. Energy measurements for EO, EA, EB, 

EC, and ED should be expressed in watt-hours 

(kJ) for conventional electric ovens, and 

volume measurements for VA, VB, VC, and VD

should be expressed in standard cubic feet 

(L) of gas for conventional gas ovens. For a 

gas oven that can be operated with or without 

forced convection, measure in watt-hours (kJ) 

any electrical energy consumed by an 

ignition device or other electrical 

components required for the operation of a 

conventional gas oven while heating the test 

block to TO using the forced convection 

mode, (EIO)1, and without using the forced 

convection mode, (EIO)2. 

3.2.1.2 Energy consumption of selfcleaning operation. Measure the energy 

consumption, ES, in watt-hours (kJ) of 

electricity or the volume of gas consumption, 

VS, in standard cubic feet (L) during the selfcleaning test set forth in section 3.1.1.1 of 

this Appendix. For a gas oven, also measure 

in watt-hours (kJ) any electrical energy, EIS, 

consumed by ignition devices or other 

electrical components required during the 

self-cleaning test.

3.2.1.4 Standby mode and off mode 

energy consumption. Make measurements as 

specified in section 3.1.1.3 of this Appendix. 

If the conventional oven is capable of 

operating in inactive mode, measure the 

average inactive mode power of the 

conventional oven, PIA, in watts as specified 

in section 3.1.1.3.1 of this Appendix. If the 

conventional oven is capable of operating in 

off mode, measure the average off mode 

power of the conventional oven, POM, in 

watts as specified in section 3.1.1.3.2 of this 

Appendix. If the conventional oven is 

capable of operating in cycle finished mode, 

measure the average cycle finished mode 

power of the conventional oven, PCF, in watts 

as specified in section 3.1.1.3.3 of this 

Appendix. 

3.2.2 Conventional surface unit test 

energy consumption. 

3.2.2.1 Conventional surface unit average 

test energy consumption. For the surface unit 

under test, measure the energy consumption, 

ECT, in watt-hours (kJ) of electricity or the 

volume of gas consumption, VCT, in standard 

cubic feet (L) of gas and the test block 

temperature, TCT, at the end of the 15 minute 

(reduced input setting) test interval for the 

test specified in section 3.1.2 of this 

Appendix and the total time, tCT, in hours, 

that the unit is under test. Measure any 

electrical energy, EIC, consumed by an 

ignition device of a gas heating element or 

other electrical components required for the 

operation of the conventional gas cooktop in 

watt-hours (kJ).

output of each component divided by the 

sum of the total annual energy consumption 

of each component. The integrated energy 

factor of other combinations of ovens and 

cooktops is the sum of the annual useful 

cooking energy output of each component 

divided by the sum of the total integrated 

annual energy consumption of each 

component. 

6. Appendix X to subpart B of part 

430 is revised to read as follows: 

Appendix X to Subpart B of Part 430— 

Uniform Test Method for Measuring the 

Energy Consumption of Dehumidifiers 

Note: The procedures and calculations that 

refer to standby mode and off mode energy 

consumption (i.e., sections 3.2, 3.2.1 through 

3.2.4, 4.2, 4.2.1 through 4.2.4, 5.1, and 5.2 of 

this Appendix X) need not be performed to 

determine compliance with energy 

conservation standards for dehumidifiers at 

this time. However, any representation 

related to standby mode and off mode energy 

consumption of these products made after 

(date 180 days after date of publication of the 

test procedure final rule in the Federal 

Register) must be based upon results 

generated under this test procedure, 

consistent with the requirements of 42 U.S.C. 

6293(c)(2). After July 1, 2010, any adopted 

energy conservation standard shall 

incorporate standby mode and off mode 

energy consumption, and upon the 

compliance date for such standards, 

compliance with the applicable provisions of 

this test procedure will also be required. 

1. Scope 

This Appendix covers the test 

requirements used to measure the energy 

performance of dehumidifiers. 

2. Definitions 

a. Active mode means a mode in which a 

dehumidifier is connected to a mains power 

source, has been activated, and is performing 

the main functions of removing moisture 

from air by drawing moist air over a 

refrigerated coil using a fan, or circulating air 

through activation of the fan without 

activation of the refrigeration system. 

b. Bucket full/removed mode means a 

standby mode in which the dehumidifier has 

automatically powered off its main function 

by detecting when the water bucket is full or 

has been removed. 

c. Energy factor for dehumidifiers means a 

measure of energy efficiency of a 

dehumidifier calculated by dividing the 

water removed from the air by the energy 

consumed, measured in liters per kilowatthour (L/kWh). 

d. IEC 62301 means the test standard 

published by the International 

Electrotechnical Commission, titled 

‘‘Household electrical appliances— 

Measurement of standby power,’’ Publication 

62301 (Edition 2.0 2011–01) (incorporated by 

reference; see § 430.3). 

e. Inactive mode means a standby mode 

that facilitates the activation of active mode 

by remote switch (including remote control), 

internal sensor, or timer, or that provides 

continuous status display. 

f. Off mode means a mode in which the 

dehumidifier is connected to a mains power 

source and is not providing any active mode 

or standby mode function, and where the 

mode may persist for an indefinite time. An 

indicator that only shows the user that the 

dehumidifier is in the off position is 

included within the classification of an off 

mode. 

g. Off-cycle mode means a standby mode 

in which the dehumidifier: 

(1) Has cycled off its main function by 

humidistat or humidity sensor; 

(2) Does not have its fan or blower 

operating; and 

(3) Will reactivate the main function 

according to the humidistat or humidity 

sensor signal. 

h. Product capacity for dehumidifiers 

means a measure of the ability of the 

dehumidifier to remove moisture from its 

surrounding atmosphere, measured in pints 

collected per 24 hours of continuous 

operation. 

i. Standby mode means any modes where 

the dehumidifier is connected to a mains 

power source and offers one or more of the 

following user-oriented or protective 

functions which may persist for an indefinite 

time: 

(1) To facilitate the activation of other 

modes (including activation or deactivation 

of active mode) by remote switch (including 

remote control), internal sensor, or timer; 

(2) Continuous functions, including 

information or status displays (including 

clocks) or sensor-based functions. A timer is 

a continuous clock function (which may or 

may not be associated with a display) that 

provides regular scheduled tasks (e.g., 

switching) and that operates on a continuous 

basis. 

3. Test Apparatus and General Instructions 

3.1 Active mode. The test apparatus and 

instructions for testing dehumidifiers shall 

conform to the requirements specified in 

Section 1, ‘‘Definitions,’’ Section 2, 

‘‘Qualifying Products,’’ and Section 4, ‘‘Test 

Criteria,’’ of the EPA’s ‘‘ENERGY STAR 

Program Requirements for Dehumidifiers,’’ 

effective January 1, 2001 (incorporated by 

reference, see § 430.3). Record measurements 

at the resolution of the test instrumentation. 

Round off calculations to the same number 

of significant digits as the previous step. 

Round the final minimum energy factor value 

to two decimal places as follows: 

(i) A fractional number at or above the 

midpoint between two consecutive decimal 

places shall be rounded up to the higher of 

the two decimal places; or 

(ii) A fractional number below the 

midpoint between two consecutive decimal 

places shall be rounded down to the lower 

of the two decimal places. 

3.2 Standby mode and off mode. 

3.2.1 Installation requirements. For the 

standby mode and off mode testing, the 

dehumidifier shall be installed in accordance 

with Section 5, Paragraph 5.2 of IEC 62301 

(incorporated by reference, see § 430.3), 

disregarding the provisions regarding

mode and off mode annual energy 

consumption for dehumidifiers, ETSO,

expressed in kilowatt-hours per year, 

according to the following: 

ETSO = [(PIA × SIA) + (POC × SOC) + (PBFR ×

per year, defined as: 

If the dehumidifier has bucket full/ 

removed mode, STOT equals 3,024 hours; 

If the dehumidifier does not have bucket 

full/removed mode, STOT equals 3,681 hours;

annual hours, SOC, is equal to 0; 

If the dehumidifier has an inactive mode 

but no off-cycle mode or off mode, the 

inactive mode annual hours, SIA, is equal to 

STOT, and the off-cycle mode annual hours, 

SOC, and the off mode annual hours, SOM, are 

each equal to 0; 

If the dehumidifier has an off-cycle mode 

and off mode but no inactive mode, the offcycle mode annual hours, SOC, is equal to 

STOT/2; the off mode annual hours, SOM, is 

equal to STOT/2; and the inactive mode 

annual hours, SIA, is equal to 0; 

If the dehumidifier has an off-cycle mode 

but no off mode or inactive mode, the offcycle mode annual hours, SOC, is equal to 

STOT, and the off mode annual hours, SOM, 

and the inactive mode annual hours, SIA, are 

each equal to 0; 

If the dehumidifier has an off mode but no 

inactive mode or off-cycle mode, the off 

mode annual hours, SOM, is equal to STOT, 

and the inactive mode annual hours, SIA, and 

the off-cycle mode annual hours, SOC, are 

both equal to 0; 

If the dehumidifier has an inactive mode, 

off-cycle mode, and off mode, the inactive 

mode annual hours, SIA, is equal to STOT/3; 

the off-cycle mode annual hours, SOC, is 

equal to STOT/3; and the off mode annual 

hours, SOM, is equal to STOT/3; 

SBFR = 657, dehumidifier bucket full/ 

removed mode annual hours; 

K = 0.001 kWh/Wh conversion factor for 

watt-hours to kilowatt-hours. 

5.2 Integrated energy factor. Calculate the 

integrated energy factor, IEF, expressed in 

liters per kilowatt-hour, rounded to two 

decimal places, according to the following: 

IEF = LW/(Eactive + ((ETSO × 24)/Sactive)) 

Where: 

LW = water removed from the air during 

dehumidifier energy factor test, in liters, 

as measured in section 4.1 of this 

Appendix. 

Eactive = dehumidifier energy factor test 

energy consumption, in kilowatt-hours, 

as measured in section 4.1 of this 

Appendix. 

ETSO = standby mode and off mode annual 

energy consumption, in kilowatt-hours 

per year, as calculated in section 5.1 of 

this Appendix.
