E. 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. Appropriateness of measurement 

instrument uncertainty requirements of 

IEC Standard 62301 (Second Edition). 

DOE invites comment on the 

appropriateness of the measurement 

instrument uncertainty requirements 

specified in Section 4.4 of IEC Standard 

62301 (Second Edition) to measure 

standby mode and off mode power 

consumption for residential furnaces 

and boilers. 

2. Adequacy of the measurement 

approach described in IEC Standard 

62301 (Second Edition). DOE invites 

comments on the adequacy of the 

measurement provisions described in 

Section 5 of IEC Standard 62301 

(Second Edition) to measure standby 

mode and off mode power consumption 

for residential furnaces and boilers. 

3. Adequacy of clarification 

statements. DOE invites comments on 

the adequacy of incorporating into DOE 

regulations the following specific 

provisions from IEC Standard 62301 

(Second Edition): Section 4.4 and 

section 5 of IEC 62301 with the 

clarification statements in Section 8 of 

the DOE test procedures. 

4. Adequacy of rounding guidance. 

DOE invites comment on the 

incorporation of the IEC Standard 62301 

(Second Edition) rounding guidance 

into the DOE test procedures’ proposed 

measurements of PW,SB and PW,OFF.

5. Adequacy of existing sampling 

plans. DOE invites comment on the 

application of the existing DOE 

sampling plans to standby mode and off 

mode measures of energy consumption, 

in particular by the newly proposed 

metrics PW,SB and PW,OFF.

SUMMARY: On August 30, 2010, the U.S. 

Department of Energy (DOE) published 

a notice of proposed rulemaking (NOPR) 

in which DOE proposed to amend, 

where appropriate, its test procedures 

for residential water heaters, direct

consumption, as required by the Energy 

Independence and Security Act of 2007 

(EISA 2007). (DOE notes that the test 

procedure and metric for residential 

water heaters currently address and 

incorporate standby mode and off mode 

energy consumption, so DOE has 

tentatively concluded that no related 

amendments are required for those 

products.). These proposed test 

procedure amendments are primarily 

based on provisions of the International 

Electrotechnical Commission (IEC) 

Standard 62301, ‘‘Household electrical 

appliances—Measurement of standby 

power,’’ that DOE would incorporate by 

reference into its regulations. The NOPR 

relied upon IEC Standard 62301 (First 

Edition 2005–06), which was the most 

current version at the time. However, 

the IEC recently adopted a new version 

of its standard which includes a number 

of methodological changes designed to 

increase accuracy while reducing testing 

burden. DOE’s review suggests that this 

document represents an improvement 

over the prior version. Accordingly, 

today’s supplemental notice of proposed 

rulemaking (SNOPR) proposes to 

incorporate the latest edition of that 

standard—IEC Standard 62301 (Second 

Edition 2011). 

DATES: DOE will accept comments, data, 

and information regarding this SNOPR 

no later than October 13, 2011. For 

details, see section V, ‘‘Public 

Participation,’’ of this SNOPR.

I. Background and Authority 

Title III, Part B1 of the Energy Policy 

and Conservation Act of 1975 (EPCA or 

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

6291–6309, as codified) sets forth a 

variety of provisions designed to 

improve energy efficiency and 

established the Energy Conservation 

Program for Consumer Products Other 

Than Automobiles, a program covering 

most major household appliances, 

including residential water heaters, 

direct heating equipment, and pool 

heaters (all of which are referenced 

below as ‘‘covered products’’).2 (42 

U.S.C. 6292(a)(4), (9), and (11); 42 

U.S.C. 6295(e)) 

Under the Act, this program consists 

essentially of three parts: (1) Testing; (2) 

labeling; and (3) establishing Federal 

energy conservation standards. The 

testing requirements consist of test 

procedures that manufacturers of 

covered products must use as the basis 

for certifying to DOE that their products 

comply with applicable energy 

conservation standards adopted 

pursuant to EPCA and for representing 

the efficiency of those products. (42 

U.S.C. 6293(c); 42 U.S.C. 6295(s)) 

Similarly, DOE must use these test 

procedures in any enforcement action to 

determine whether covered products 

comply with these energy conservation 

standards. (42 U.S.C. 6295(s)) Under 42 

U.S.C. 6293, EPCA sets forth criteria and 

procedures for DOE’s adoption and 

amendment of such test procedures. 

Specifically, EPCA provides 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 


emcdonald on DSK5VPTVN1PROD with PROPOSALS
Federal Register / Vol. 76, No. 177 / Tuesday, September 13, 2011 / Proposed Rules 56349 

3EISA 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. 

* * * 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 

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: (1) 

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 (2) 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.3 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). 

DOE’s current test procedures for 

residential water heaters, direct heating 

equipment, and pool heaters are found 

at 10 CFR part 430, subpart B in 

Appendix E (water heaters), Appendices 

G and O (direct heating equipment), and 

Appendix P (pool heaters). These 

procedures establish a means for 

determining measures of energy 

consumption, including, where 

appropriate, energy efficiency. On 

August 30, 2010, DOE published its 

NOPR (hereafter referred to as the 

August 2010 NOPR) to consider 

amendments to the test procedures for 

residential water heaters, direct heating 

equipment, and pool heaters to account 

for the standby mode and off mode 

energy consumption of these products, 

as required by EISA 2007. 75 FR 52892 

(Aug. 30, 2010). For a more detailed 

procedural history of the test procedure 

rulemaking to address standby mode 

and off mode energy consumption of 

residential water heaters, direct heating 

equipment, and pool heaters, please 

consult the August 2010 NOPR. Id. at 

52893–95. This SNOPR builds upon and 

further modifies DOE’s proposal, as 

presented in the August 2010 NOPR. 

II. Summary of the Supplemental 

Proposed Rule 

As discussed above, EISA 2007 

amended EPCA to require that DOE test 

procedures for covered products include 

provisions for measuring standby mode 

and off mode energy consumption. (42 

U.S.C. 6295(gg)(2)(A)) EISA 2007 

requires consideration of the most 

current version of IEC Standard 62301 

to support the added measurement 

provisions. Id. In the August 2010 

NOPR, DOE proposed to amend its test 

procedures to prescribe the use of IEC 

Standard 62301, ‘‘Household electrical 

appliances—Measurement of standby 

power,’’ Publication 62301 First Edition 

2005–06,’’ which was the most current 

version of this standard at the time DOE 

proposed its incorporation into the DOE 

regulations. Since that time, a second 

edition of the standard has been 

developed and finalized. In the abstract 

of the January 27, 2011 final 

publication, the IEC reports that the 

second edition would provide practical 

improvement and possible reduction in 

testing burden, and, as discussed in 

further detail below, commenters on the 

August 2010 NOPR expressed similar 

views. DOE has reviewed IEC Standard 

62301 (Second Edition) and agrees that 

the second edition does provide for 

improvement in terms of measurement 

accuracy and possible reduced testing 

burden. Accordingly, in today’s NOPR, 

DOE is proposing to incorporate into 

DOE’s test procedure regulations the 

second edition of the IEC 62301 

standard in its entirety, and to call out 

the appropriate provisions of that 

standard in DOE’s test procedure 

regulations for residential direct heating 

equipment and pool heaters. (Because 

DOE continues to believe that the 

current test procedure for residential 

water heaters fully addresses standby 

mode and off mode energy 

consumption, this SNOPR proposes no 

amendments to the test procedure for 

these products.) 

III. Discussion 

A. Use of IEC Standard 62301 (Second 

Edition), ‘‘Household Electrical 

Appliances—Measurement of Standby 

Power’’ 

As noted above, EPCA, as amended by 

EISA 2007, requires that DOE test 

procedures be amended to include 

standby mode and off mode energy 

consumption, taking into consideration 

the most current versions of Standards 

62301 and 62087 of the International 

Electrotechnical Commission. (42 U.S.C. 

6295(gg)(2)(A)) The August 2010 NOPR 

would reference IEC Standard 62301 

(First Edition) to obtain the standby 

mode and off mode measured wattage 

for residential direct heating equipment 

and pool heaters. 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 IEC 

Standard 62301 (First Edition) and 

tentatively concluded in its August 2010 

NOPR (75 FR 52892 (August 30, 2010)) 

that it was generally applicable to 

residential direct heating equipment 

and pool heaters, although some 

clarification was needed. Specifically, 

because there is a possible conflict with 

voltage and ambient temperature 

provisions of the existing procedures, 

the August 2010 NOPR clarified where 

the IEC provisions apply and where the 

existing test procedure provisions 

apply. With this clarification in place, 

the August 2010 NOPR proposed to 


emcdonald on DSK5VPTVN1PROD with PROPOSALS
56350 Federal Register / Vol. 76, No. 177 / Tuesday, September 13, 2011 / Proposed Rules 

reference IEC Standard 62301 (First 

Edition) for obtaining the standby mode 

and off mode wattage measurements for 

residential direct heating equipment 

and pool heaters. 

In written comments on the August 

2010 NOPR, the Air-Conditioning, 

Heating, and Refrigeration Institute 

(AHRI) and the Association of Home 

Appliance Manufacturers (AHAM) 

asked that DOE consider referencing a 

revised version of the industry 

standard—IEC Standard 62301 (Second 

Edition). Both commenters cited 

technical improvements in the latter 

version that they expect would enhance 

repeatability and reproducibility of test 

results. (AHRI, No. 13 at p. 1, AHAM, 

No. 15 at p. 2) AHAM additionally 

commented that the Final Draft 

International Standard (FDIS) version of 

IEC Standard 62301 would be preferable 

to the Committee Draft for Vote (CDV) 

version of the standard. (AHAM, No. 15 

at p. 2) The CDV of IEC Standard 62301 

was released on August 28, 2009. On 

this matter, DOE notes that because IEC 

has now formally adopted IEC Standard 

62301 (Second Edition), DOE is no 

longer considering earlier draft versions. 

In any event, the adopted version is 

consistent with the preference suggested 

by AHAM. 

As noted above, since the time of the 

August 2010 NOPR, the IEC Standard 

62301 technical committee has revised 

its standard. Specifically, a second 

edition of IEC Standard 62301 has been 

issued by IEC with a final publication 

date of January 27, 2011. This standard 

can be purchased at: http://www.iec.ch/ 

index.htm. The IEC reports in its 

abstract to the January 27, 2011 final 

publication that the second edition 

provides technical improvement from 

the previous edition as follows: 

• Greater detail in set-up procedures 

and introduction of stability 

requirements for all measurement 

methods to ensure that results are as 

representative as possible; 

• Refinement of measurement 

uncertainty requirements for power 

measuring instruments, especially for 

more difficult loads with high crest 

factor and/or low power factor; 

• Updated guidance on product 

configuration, instrumentation, and 

calculation of measurement uncertainty. 

DOE has conducted a review of the 

second edition of IEC Standard 62301, 

which is consistent with the 

requirement in EISA 2007 for DOE to 

consider the most current version of that 

standard. (42 U.S.C. 6295(gg)(2)(A)) As 

a result of its investigation, DOE agrees 

with the commenters mentioned above 

(AHRI, No. 13 at p. 1, AHAM, No. 15 

at p.2), that some improvement is 

possible with the incorporation of the 

second edition as it applies to the 

products that are the subject of this 

rulemaking. Specifically, IEC Standard 

62301 (Second Edition) revises the 

standard’s power measurement accuracy 

provisions, based on technical 

submissions that showed the inability to 

achieve the accuracy levels required by 

the first edition for certain operating 

regimes with the use of typical 

instrumentation. A more comprehensive 

specification of required accuracy is 

provided in IEC Standard 62301 

(Second Edition) that depends upon the 

characteristics of the power being 

measured. The other major change in 

IEC Standard 62301 (Second Edition) 

that relates to the measurement of 

standby power consumption in covered 

products involves the specification of 

the stability criteria required to measure 

that power. IEC Standard 62301 (Second 

Edition) contains more detailed 

techniques to evaluate the stability of 

the power consumption and to measure 

the power consumption for loads with 

different stability characteristics. The 

manufacturer is given a choice of 

measurement procedures, including less 

burdensome methods such as direct 

meter reading methods. The less 

burdensome methods are allowed if 

certain clearly described conditions are 

met. DOE believes that the changes 

incorporated in IEC Standard 62301 

(Second Edition) would allow for use of 

less burdensome methods when 

appropriate and would ensure accurate 

measures of standby energy 

consumption over a range of operating 

conditions that may be present in 

residential heating products. 

Accordingly, for the reasons 

discussed above, DOE is proposing to 

incorporate IEC Standard 62301 (Second 

Edition) into DOE’s test procedure 

regulations for residential direct heating 

equipment and pool heaters. To this 

end, this supplemental notice is 

proposing to add a new reference in 10 

CFR 430.3 for IEC Standard 62301 

(Second Edition) alongside the existing 

reference to IEC Standard 62301 (First 

Edition). (Although DOE has tentatively 

determined that the provisions of IEC 

Standard 62301 (Second Edition) should 

be made applicable to residential direct 

heating equipment and pool heaters, the 

Department is currently maintaining the 

existing reference to IEC Standard 62301 

(First Edition), because other products 

continue to reference that standard.) In 

addition, DOE is proposing a number of 

editorial changes in the various 

appendices (G, O, P) which are 

necessary for residential direct heating 

equipment and pool heaters to allow for 

the correct referencing. For example, the 

definition sections of the individual 

appendices need to define 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 DOE’s 

various test procedures. Finally, as an 

editorial improvement, DOE is unifying 

the standby mode and off mode 

nomenclature used in the various test 

procedures. Specifically, the uniform 

nomenclature would use the 

expressions: PW,SB and PW,OFF in all test 

procedures. All of these proposed 

changes are reflected in the regulatory 

text which can be found at the end of 

this SNOPR. 

B. Rounding Guidance 

IEC Standard 62301 (Second Edition) 

includes specific guidance on rounding 

for the various wattage measurements. 

For clarification purposes, DOE is 

proposing to include the IEC rounding 

guidance in this supplemental proposal. 

Specifically, it is proposed that the 

following sentence be added to the 

measurement provisions of the 

proposed regulatory text where 

appropriate: ‘‘The recorded standby 

power (PW,SB) (or off mode power 

PW,OFF, where appropriate) shall be 

rounded to the second decimal place, 

and for loads greater than or equal to 

10W, at least three significant figures 

shall be reported.’’ DOE requests 

comments as to the adequacy and 

appropriateness of this additional 

clarification. 

C. Sampling Plans for Standby Mode 

and Off Mode 

Currently, sampling plans for the 

products that are the subject of this 

proposal are located in 10 CFR 429.17 

for water heaters, 10 CFR 429.22 for 

direct heating equipment, and 10 CFR 

429.24 for pool heaters. These 

provisions specify the number of units 

of each basic model that a manufacturer 

must test to calculate the certified 

ratings for compliance and 

representation purposes. The sampling 

procedures provide that ‘‘ * * * a 

sample of sufficient size shall be 

randomly selected and tested to ensure 

[compliance].’’ Id. For these products, a 

minimum of two units must be tested in 

order for a manufacturer to calculate the 

certified rating for each basic model, 

make representations about the basic 

model’s energy consumption or 

efficiency, and certify compliance to the 

Department. This minimum is implicit 

in the requirement to calculate a mean— 

an average—which requires at least two 

values, and is consistent with the 


emcdonald on DSK5VPTVN1PROD with PROPOSALS
Federal Register / Vol. 76, No. 177 / Tuesday, September 13, 2011 / Proposed Rules 56351 

4 In general, DOE presents sampling calculations 

for both energy consumption and energy efficiency 

standards throughout 10 CFR part 429. Consumers 

prefer lower values for measures of energy 

consumption (i.e., thereby ensuring that the 

appliance in question uses less energy, which 

would translate into lower energy bills). 

Conversely, consumers generally prefer higher 

values for measures of energy efficiency (i.e., 

thereby ensuring that the appliance in question 

performs its operation using less energy over a 

given period of time, which again would translate 

into lower energy bills). 

general rule articulated under 10 CFR 

429.11(b). Under no circumstances is a 

sample size of one (1) authorized. 

Manufacturers may need to test more 

than two samples depending on the 

variability of their sample. 

Consequently, DOE is proposing here 

that the existing DOE sampling plans for 

residential water heaters, direct heating 

equipment, and pool heaters be applied 

to the measurement of standby mode 

and off mode energy consumption. 

Specifically, the proposed wattage 

measurements (i.e., PW,SB and PW,OFF), 

as well as any other measure of energy 

consumption based on these values, 

would be subject to those sampling plan 

provisions contained in 10 CFR 429.22 

for direct heating equipment and 10 

CFR 429.24 for pool heaters. (Note: No 

added measures of energy consumption 

are proposed for residential water 

heaters.) Clarifying further, the wattage 

measurements would be subject to the 

sampling provisions applicable to 

measures of energy consumption.4 DOE 

invites comment on the application of 

the existing DOE sampling plans to 

standby mode and off mode measures of 

energy consumption, in particular the 

newly proposed metrics PW,SB and 

PW,OFF. 

D. Effective Date and Compliance Date 

The effective date for these 

amendments would be 30 days after 

publication of the test procedure final 

rule in the Federal Register. At that 

time, representations may be made 

using the new metrics PW,SB and PW,OFF

and any other measure of energy 

consumption which depends on PW,SB

and PW,OFF, which were adopted 

pursuant to these amendments. The 

compliance date for any representations 

relating to standby mode and off mode 

is 180 days from date of publication of 

the test procedure final rule in the 

Federal Register; on or after that date, 

any such representations must be based 

upon results generated under these test 

procedures and sampling plans. 

However, DOE would clarify that use 

of these proposed test procedure 

amendments related to standby mode 

and off mode energy consumption 

would not be required for purposes of 

energy conservation standards 

compliance, until the compliance date 

of the next standards final rule that 

addresses standby mode and off mode. 

E. Compliance With Other EPCA 

Requirements 

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)) 

Today’s supplemental proposed 

amendments to the DOE test procedures 

for direct heating equipment and pool 

heaters would incorporate the most 

current version of IEC Standard 62301 

in lieu of the previous version. DOE 

believes these new provisions would 

produce valid results, while reducing 

testing burden. Accordingly, this 

proposal would meet the requirements 

of 42 U.S.C. 6293(b)(3). 

In addition, DOE has determined that 

these amendments would not alter the 

measured efficiency used by the current 

energy conservation standard for these 

products. (42 U.S.C. 6293(e)(1)) 

Consistent with its mandate pursuant to 

EISA 2007, DOE is clarifying in this 

SNOPR that use of these proposed test 

procedure amendments related to 

standby mode and off mode energy 

consumption would not be required for 

purposes of energy conservation 

standards compliance, until the 

compliance date of the next standards 

final rule that addresses standby mode 

and off mode. That standards 

rulemaking will factor in these new test 

procedure amendments when setting an 

appropriate standard level. Accordingly, 

no modifications to the applicable 

energy conservation standards are 

required at this time. (42 U.S.C. 

6293(e)(2)) 

IV. Procedural Issues and Regulatory 

Review 

DOE has concluded that the 

determinations made pursuant to the 

various procedural requirements 

applicable to the August 30, 2010 NOPR 

remain unchanged for this SNOPR. 

These determinations are set forth in the 

August 30, 2010 NOPR. 75 FR 52892, 

52901–03. If anything, the additional 

changes proposed in this SNOPR (e.g., 

different options for stability criteria) 

would be expected to further reduce 

testing burden beyond what is specified 

in the August 30, 2010 NOPR. 

V. Public Participation 

DOE will accept comments, data, and 

information regarding the SNOPR no 

later than the date provided at the 

beginning of this notice. Comments, 

data, and information submitted to 

DOE’s e-mail address for this 

rulemaking should be provided in 

WordPerfect, Microsoft Word, PDF, or 

text (ASCII) file format. Stakeholders 

should avoid the use of special 

characters or any form of encryption, 

and wherever possible comments 

should include the electronic signature 

of the author. Comments, data, and 

information submitted to DOE via mail 

or hand delivery/courier should include 

one signed paper original. No 

telefacsimiles (faxes) will be accepted. 

Pursuant to 10 CFR 1004.11, any 

person submitting information that he 

or she believes to be confidential and 

exempt by law from public disclosure 

should submit two copies: One copy of 

the document that includes all of the 

information believed to be confidential, 

and one copy of the document with that 

information deleted. DOE will 

determine the confidential status of the 

information and treat it accordingly. 

Factors of interest to DOE when 

evaluating requests to treat submitted 

information as confidential include the 

following: (1) A description of the items; 

(2) whether and why such items are 

customarily treated as confidential 

within the industry; (3) whether the

heaters so equipped. 

2.3.1 The measurement of Qp is not 

required for unvented heaters where the pilot 

light is designed to be turned off by the user 

when the heater is not in use (i.e., for units 

where turning the control to the OFF position 

will shut off the gas supply to the burner(s)

refer to standby mode and off mode energy 

consumption, (i.e., sections 3.7 and 4.7 of 

this appendix O) need not be performed to 

determine compliance with energy 

conservation standards for vented heaters at 

this time. However, any representation 

related to standby mode and off mode energy 

consumption of these products made after 

corresponding revisions to the vented home 

heating equipment test procedure must be 

based upon results generated under this test 

procedure, consistent with the requirements 

of 42 U.S.C. 6293(c)(2). For vented home 

heating equipment, the statute requires that 

after July 1, 2010, any adopted energy

3.7 Measurement of Electrical Standby 

Mode and Off Mode Power 

3.7.1 Standby power measurements. With 

all electrical auxiliaries of the vented heater 

not activated, measure the standby power 

(PW,SB) in accordance with the procedures in 

IEC 62301 (incorporated by reference, see 

§ 430.3), except that section 2.9, Room 

ambient temperature, and the voltage 

provision of section 2.3.5, Electrical supply, 

of this appendix shall apply in lieu of the IEC 

62301 corresponding sections 4.2, Test room, 

and 4.3, Power supply. Clarifying further, the 

IEC 62301 sections 4.4, Power measuring 

instruments, and section 5, Measurements, 

shall apply in lieu of section 2.8, Energy flow 

instrumentation, of this appendix. Measure 

the wattage so that all possible standby mode 

wattage for the entire appliance is recorded, 

not just the standby mode wattage of a single 

auxiliary. The recorded standby power 

(PW,SB) shall be rounded to the second 

decimal place, and for loads greater than or 

equal to 10W, at least three significant figures 

shall be reported. 

3.7.2 Off mode power measurement. If 

the unit is equipped with a seasonal off 

switch or there is an expected difference 

between off mode power and standby mode 

power, measure off mode power (PW,OFF) in 

accordance with the standby power 

procedures in IEC 62301 (incorporated by 

reference, see § 430.3), except that section 

2.9, Room ambient temperature, and the 

voltage provision of section 2.3.5, Electrical 

supply, of this appendix shall apply in lieu 

of the IEC 62301 corresponding sections 4.2, 

Test room, and 4.3, Power supply. Clarifying 

further, the IEC 62301 sections 4.4, Power 

measuring instruments, and section 5, 

Measurements, shall apply in lieu of section 

2.8, Energy flow instrumentation, of this 

appendix. Measure the wattage so that all 

possible off mode wattage for the entire 

appliance is recorded, not just the off mode 

wattage of a single auxiliary. If there is no 

expected difference in off mode power and 

standby mode power, let PW,OFF = PW,SB, in 

which case no separate measurement of off 

mode power is necessary. The recorded off 

mode power (PW,OFF) shall be rounded to the 

second decimal place, and for loads greater 

than or equal to 10W, at least three 

significant figures shall be reported. 

4.0 Calculations 

* * * * * 

4.6.3 Average annual auxiliary electrical 

energy consumption for vented heaters. For 

vented heaters with single-stage controls or 

manual controls, the average annual auxiliary 

electrical consumption (EAE) is expressed in 

kilowatt-hours and defined as: 

EAE = BOHSSPE + ESO

Where: 

BOHSS = as defined in 4.6.1 of this appendix 

PE = as defined in 3.1.3 of this appendix 

ESO = as defined in 4.7 of this appendix 

4.6.3.1 For vented heaters with two-stage 

or modulating controls, EAE is defined as: 

EAE = (BOHR + BOHH)PE + ESO

Where: 

BOHR = as defined in 4.6.1 of this appendix 

BOHH = as defined in 4.6.1 of this appendix 

PE = as defined in 3.1.3 of this appendix 

ESO = as defined in 4.7 of this appendix 

* * * * * 

4.7 Average annual electric standby 

mode and off mode energy consumption. 

Calculate the annual electric standby mode 

and off mode energy consumption, ESO, 

defined as, in kilowatt-hours: 

ESO = ((PW,SB * (4160—BOH)) + (PW,OFF * 

4600)) * K 

Where: 

PW,SB = vented heater standby mode 

power, in watts, as measured in section 3.7 

4160 = average heating season hours per year 

PW,OFF = vented heater off mode power, in 

watts, as measured in section 3.7 

4600 = average non-heating season hours per 

year 

K = 0.001 kWh/Wh, conversion factor for 

watt-hours to kilowatt-hours. 

BOH = burner operating hours as calculated 

in section 4.6.1 where for single-stage 

controls or manual controls vented 

heaters BOH = BOHSS and for vented 

heaters equipped with two-stage or 

modulating controls BOH = (BOHR + 

BOHH). 

6. Appendix P to Subpart B of Part 

430 is revised to read as follows: 

Appendix P to Subpart B of Part 430– 

Uniform Test Method for Measuring the 

Energy Consumption of Pool Heaters 

Note: The procedures and calculations that 

refer to standby mode and off mode energy 

consumption (i.e., sections 2.2, 2.3, 3.2, 4.2, 

4.3, 5.3 equation (3), and 5.4 of this appendix 

P) need not be performed to determine 

compliance with energy conservation 

standards for pool heaters at this time. 

However, any representations related to 

standby mode and off mode energy 

consumption of these products made after 

corresponding revisions to the pool heaters 

test procedure must be based upon results 

generated under this test procedure, 

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

6293(c)(2). For pool heaters, the statute 

requires that 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. Definitions

Z21.56 (incorporated by reference; see 

§ 430.3). 

3.2 Standby mode and off mode. 

Following the conclusion of the 30-minute 

active mode test described in section 3.1, 

reduce the thermostat setting to a low enough 

temperature to put the pool heater into 

standby mode. Reapply the energy sources 

and operate the pool heater in standby mode 

for 60 minutes. 

4. Measurements 

4.1 Active mode. Measure the quantities 

delineated in section 2.10 of ANSI Z21.56 

(incorporated by reference; see § 430.3). The 

measurement of energy consumption for oilfired pool heaters in Btu is to be carried out 

in appropriate units (e.g., gallons). 

4.2 Standby mode. Record the average 

electric power consumption during the 

standby mode test, PW,SB, in W, in accordance 

with section 5 of IEC 62301 (incorporated by 

reference; see § 430.3) and the fossil fuel 

energy consumption during the standby test, 

Qp, in Btu. Ambient temperature and voltage 

specifications of ANSI Z21.56 (incorporated 

by reference; see § 430.3) shall apply to this 

standby mode testing. The recorded standby 

power (PW,SB) shall be rounded to the second 

decimal place, and for loads greater than or 

equal to 10W, at least three significant figures 

shall be reported. 

4.3 Off mode. 

4.3.1 Pool heaters with a seasonal off 

switch. For pool heaters with a seasonal off 

switch, the average electric power 

consumption during the off mode, PW,OFF = 

0, and the fossil fuel energy consumed during 

the off mode, Qoff = 0. 

4.3.2 Pool heaters without a seasonal off 

switch. Record the average electric power 

consumption during the standby/off mode 

test, PW,OFF (= PW,SB), in W, in accordance 

with section 5 of IEC 62301 (incorporated by 

reference; see § 430.3), and the fossil fuel 

energy consumption during the off mode test, 

Qoff (= Qp), in Btu. Ambient temperature and 

voltage specifications of ANSI Z21.56 

(incorporated by reference; see § 430.3) shall 

apply to this off mode testing. The recorded 

off mode power (PW,OFF) shall be rounded to 

the second decimal place, and for loads 

greater than or equal to 10W, at least three 

significant figures shall be reported. 

5. Calculations 

5.1 Thermal efficiency. Calculate the 

thermal efficiency, Et (expressed as a 

percent), as specified in section 2.10 of ANSI 

Z21.56 (incorporated by reference; see 

§ 430.3). The expression of fuel consumption 

for oil-fired pool heaters shall be in Btu. 

5.2 Average annual fossil fuel energy for 

pool heaters. The average annual fuel energy 

for pool heaters, EF, is defined as:

(8760¥POH) Qoff,R

Where: 

BOH = average number of burner operating 

hours = 104 h 

POH = average number of pool operating 

hours = 4464 h 

QIN = rated fuel energy input as defined 

according to section 2.10.1 or section 

2.10.2 of ANSI Z21.56 (incorporated by 

reference; see § 430.3), as appropriate. 

QPR = average energy consumption rate of 

continuously operating pilot light, if 

employed, = (QP/1 h) 

QP = energy consumption of continuously 

operating pilot light, if employed, as 

measured in section 4.2, in Btu 

8760 = number of hours in one year 

Qoff,R = average off mode fossil fuel energy 

consumption rate = Qoff/(1 h) 

Qoff = off mode energy consumption as 

defined in section 4.3 of this appendix 

5.3 Average annual auxiliary electrical 

energy consumption for pool heaters. The 

average annual auxiliary electrical energy 

consumption for pool heaters, EAE, is 

expressed in Btu and defined as: 

(1) EAE = EAE,active + EAE,standby,off

(2) EAE,active = BOH * PE 

(3) EAE,standby,off = (POH¥BOH) PW,SB(Btu/h) + 

(8760¥POH) PW,OFF(Btu/h) 

Where: 

EAE,active = auxiliary electrical consumption 

in the active mode 

EAE,standby,off = auxiliary electrical 

consumption in the standby mode and 

off mode 

PE = 2Ec, if heater is tested according to 

section 2.10.1 of ANSI Z21.56 

(incorporated by reference; see § 430.3), 

in Btu/h = 3.412 PErated, if heater is tested 

according to section 2.10.2 of ANSI 

Z21.56, in Btu/h 

Ec = electrical consumption of the heater 

(converted to equivalent unit of Btu), 

including the electrical energy to the 

recirculating pump if used, during the 

30-minute thermal efficiency test, as 

defined in section 2.10.1 of ANSI Z21.56, 

in Btu per 30 min. 

2 = conversion factor to convert unit from per 

30 min. to per h. 

PErated = nameplate rating of auxiliary 

electrical equipment of heater, in Watts 

BOH = as defined in 5.2 of this appendix 

POH = as defined in 5.2 of this appendix

consumption rate during off mode 

expressed in Btu/h = 3.412 PW,OFF, Btu/ 

h 

PW,OFF = as defined in 4.3 of this appendix 

5.4 Integrated thermal efficiency. 

5.4.1 Calculate the seasonal useful output 

of the pool heater as: 

EOUT = BOH[(Et/100)(QIN + PE)]
