SUPPLEMENTARY INFORMATION~ 

A. BACKGROUND 

The Federal Energy Administration 

<FEA> hereby amends Part 430, Chapter II of Title 10, Code of Federal Regu- lations, in order to prescribe test proce- dures for electric refrigerators, electric 

refrigerator-freezers, and freezers, 'pursuant to section 323 (42 u.s.c. 6293) of the Energy Policy and Conservation 

Act <Act> <Pub. L. 94-163). These test 

procedures were proposed by notice issued April 21, 1977 (42 FR 21584, April 17, 

1977) , and a public hearing on the pro- posed test procedures was held on 

June 14, 1977. The definitions of "refrig- erator," "refrigerator-freezer," and 

"freezer" were proposed at 41 FR 19980, 

May 14, 1976, but these definitions have 

been revised in response to public comments, as discussed below. 

By notice issued May 24, 1977 <42 FR 

27896, June 1, 1977>, FEA established 

Subparts A and B of Part 430, Chapter II of Title 10, Code of Federal Regula- tions. Certain definitions and general provisions applicable to the Energy Conservation Program For Appliances have 

been promulgated in Subpart A. Final 

test procedures for room air conditioners 

and dishwashers have been prescribed in 

Subpart B. In addition to the test pro- cedures for electric refrigerators, electric 

refrigerator-freezers, and freezers pre- scribed today, the final test procedures for clothes dryers and television sets are 

also being prescribed by separate notices. 

Several other test procedures have been

proposed for inclusion in Subpart B. FEA 

has also proposed a Subpart C for appliance energy efficiency improvement targets. An outline of the provisions of Part 

430 which have so far been established, 

including provisions in today's notices, is 

as follows:

B. DISCUSSION OF COMMEN'.l'S 

Comments were received from industry 

a trade association, and a state government. The major issues raised by the 

comments are illscussed below. 

1, TYPE OF ENERGY INPUT 

Comments were received which pointed 

out that the proposed definition of "basic 

model" for refrigerators and refrigera- tor-freezers referred to "electrical characteristics" of covered products. These 

comments questioned whether units using a non-electrical energy input were 

intended to be . covered by the proposed 

test procedures. At the time of publication of the pro- posed test procedures, FEA believed that 

refrigerators and refrigerators-freezers using an energy source other than elee--

tricity were not to.any significant extent 

distributed in commerce. Subsequently FEA has learned that a significant number of gas refrigeration products are 

manufactured, primarily for use in 

mobile homes and recreational vehicles, 

and therefore it ls asldng NBS to develop 

test procedures for these covered prod· 

ucts. · 

The test procedures prescribed today for electric refrigerators and electric refrigerator-freezers reflect minor edlt-0rlal 

and definitfonal changes which were 

necessary to clarify that these proce- dures apply only to electric refrigerators and electric refrigerator-freezers. This 

entailed redefining "refrigerator" and 

"refrigerator-freezer" and modifying the 

proposed definitions to apply only to the 

class of electric refrigerators and electric 

refrigerator-freezers. Section 323 of the 

Act authorizes the development of test 

procedures for classes of a covered prod· 

uct type. Test procedures for the class of 

gas refrigerators and gas refrigerator• freezers will be proposed as soon as 

practicable, in keeping with the notice 

issued July 22, 1976 (41 FR 31237, July 27, 1976) which delayed the proposal of 

test procedures for refrigerators and re• 

frigerator-freezers beyond the date con• 

templated by the Act. 

Because FEA is unaware of any freezers intended for personal use or 

consumption which use an energy source 

other than electricity, it has not asked 

NBS to develop any additional test pro- cedures for freezers. 'Ilhe test proce- dures prescribed today for freezers, 

however, do reflect a minor definitional 

change to indicate that only electric 

freezers are presently intended to be covered by these test pr.ocedures. 

2. ANNUAL OPERATING cosr 

Several comments suggested that a 50-

percent use credit for an antisweat heater switch, such as the credit allowed in 

the energy factor calculations, also bc 

allowed in the estimated annual operat- ing cost calculations. FEA agrees that 

such an adjustment of the estimated 

annual operating cost calculations is· 

necessary if the estimated annual op- erating cost figure is to be logically consistent with the energy factor. Without 

the adjustment, two products which aro 

identical except for an antisweat heater 

switch on one would have the same annual operating cost figure, but the unit 

with the antisweat heater switch would 

have a lower energy factor. This would 

be confusing to consumers. Therefore, 

the estimated annual operating cost for 

electric refrigerators, electric refrigera- tor-freezers, and freezers has been 

amended in §§ 430.22(a) CU and 430.22 

Cb) (1) to r~ect these changes. 

One- comment stated that no credit 

should be applied either to the energy factor or to the cost of operation, because such a credit would be a disin· 

centive for manufacturers to remove 

the ne~.d for antisweat heaters (e.g., by improving the insulation of their products>. However, NBS has verified that 

the antisweat heater switch is indeed 

used when available in refrigeration 

FEDERAL REGISTER, VOL. 42, NO. 178-WEDNESDAY, SEPTEMBER 1~, 1977 ~ 
pr6ducts, and that such products therefore use less energy than similar units 

without the switch. For these reasons, 

FEA has determined that a. use credit 

for an antisweat heater switch is ap- propriate both for the annual operating 

cost and for the energy faetor calcUlations. ' 

Several comments suggested that the 

use credit should be a. :figure other than 

50 percent, but no supporting information was supplied which :was not pre- viously considered in arriving at the 50 

percent credit recommended by NBS and 

adopted by F.EA as best reflecting actual 

consumer use of antisweat }leaters. 

One comment suggested that monthly operating cost be included as another 

measure of energy consumption. FEA 

does not believe that a measure of 

monthly operating cost would signtlicantly add to the information conveyed by the estiniated annual operating 

cost. the inclusion of which is mandated 

bytheAct. 

3. ENERGY FAC'IOR FOR FREEZERS 

Some comments suggested that calculation of an unadjusted energy factor 

for freezers would lead consumers to believe that freezers are less efficient than 

electric refrigerators and electric refrigerator-freezers. These comments 

noted that the energy factor for electric refrigerators having a 15° F. freezer 

compartment is adjusted by a factor of 

1.44, and that the energy factor for electric refrigerator-freezers having a. 5° F. 

• freezer compartment is adjusted by a. 

·factor of 1.63 FEA has determined that 

consistency requires that the calculation of the energy factor for freezers include an adjustment factor of 1.73, in 

order to compensate for the lower working temperature of freezers. The energy 

factor for .freezers has been amended in 

§ 430.22<b> <4> to reflect this change. 

Because neither the energy factor nor 

the adjusted volume is used in the de- . termination of the estimated annual operating cost, this adjustment factor will 

not affect those calculations. The 1972 

baseline emciency on which the proposed 

energy ~iency improvement target for 

freezers <42 FR 36648, July 15, 1977> was 

based, Will be affected, however. AB a 

result, appropriate changes will be 

made in the energy factors associated 

with the target for freezers. 

4. ADJUSTING THE ENERGY FACTOR· 

One commenter suggested that the 

concepts of an adjusted refrigerated volume and an energy factor·be abandoned 

on the grounds that they compromise manufacturers' incentive to add extia 

insulation to freezer compartments and 

so discourage the use of optimal insulation thicknesses. While the concept of 

the energy factor as proposed is imper- fect, FEA believes that the "alternative of 

allowing no compensation for the lower 

oPerating temperatures of freezing compartments places at an unreasonable 

dl,,advantage those units with higher ratios af freezer volume to refrigerator volume. · 

RULES AND REGULATIONS 

In theory, a. 63-percent increase in 

freezer compartment insulation would 

obviate the need !or an adjustment !actor. In practice, however, the conductance of the freezer compartment insulation of most currently a.\-allable refrig- erator-freezers is within 25 percent of 

the conductance of the re!rlgerotor compartment insulation. For this reason, 

FEA believes that the concept; of an adjusted energy factor 1s appropriate as a 

measure of energy consumption which 

will nssist consumers in making purchasing decisions, as required by the Act. 

AB noted above, FEA has decided not onJy 

to retain en adjusted energy !actor !or 

electric refrigerators nnd electric refrig- erator-freezers, but also to extend this 

concept to freezers. 

The same commenter also suggested that the energy !actor favors larger units 

because the mo.,!or heat transfer mechanisms are more dependent upon area 

than volume. However, the ut!llty of a. refrigeration product is a. refiectlon of 

its volume and not its sur!ace nrea, and 

the measure of emciency would reflect 

this utlllty. For example, the energy !actor correctly indicates that one large unit is pre!erable to two smaller units 

with the same total volume. 

5, CREDIT FOR OTHER ENERGY SAVING DEVICES 

FEA and NBS are currently studying the advisablllty of a. credit !or a. switch 

to interrupt operation of a unit/s evaporator fan when the unit's door is open. Special credit may be appropriate because the test procedures prescribed today involve a cycle type with doors remaining closed, so that nny advantages of such a. device would not be reflected. 

FEA is prepared to amend these test 

procedures 1! further developments indicate that energy saving devices a.re 

given inappropriate qredit due to dlfierences between the test procedures and 

actual consumer use. 

CS. TEST VOLTAGE 

several comments were directed to 

proposed §430.23 <a.><3> and Cb>C3>, 

which required basic moqels having a 

dual voltage rating to be tested at each 

-design voltage. All household electric refrigerators, electric re!rigerntor-treezers, and freezers in the United States a.re 

designed to operate at a nominal 115 

volt. 60 HZ circuit. and any other nameplate voltage rating is Included solely 

for use outside the United stntes. Because FEA does not intend to reqUlre testing under conditions not found in the 

United States, this requirement is determined to be unduly burdensome and 

has been deleted. 

7. NUJ.tBER OF UNITS TO BE 7'ES'lll> 

Some comments expressed objections 

to the sampling provision !or electric retrlgerators, electric refrigerator-freezers, and freezers. Proposed § 430.23 Ca> and 

Cb) provided !or l!atnpling of each basic 

model to be tested when testing of electric refrigerators, electrlc re!rigerator- freezers or freezers is required by the 

Act or by program regulations of agen- cies responsible for adm1nlstering ithe 

46141 

Act. This provision was intended both to 

provide an acceptable level of assurance that test results are applicable to 

any entire basic model for which testing is required and to mlnfmlze the testing 

burden on manufacturers. 

Test procedures prescribed under section 323 o! the Act are intended ultimately to be used, !or example, for labeling under section 324, !or monitoring the progress of manufacturers toward accomplJshing the energy efficiency improvement targets under section 

325, and !or enforcement testing under 

section 326. These aspects of the appliance program have not, however. been 

implemented. It is quite JXJssilJle that 

the objectives o! appliance testing under 

each or these parts of the program, as well as the instructions as to how a test 

procedure would be applied Ce.g .. sampling of production units>. may differ. 

FEA, NBS, and FrC are continuing to 

e\'aluate the appropriate method or 

methods !or sampling the units to be 

tested in order to comply with the statute and satisfy all of the diirerent elements of the appliance program. Whlle the various parts of the ap- pliance program identified above are not 

in eJiect at this time, section 323Cc> of 

the Act provides: 

En'ecU..-e 90 days a!ter a test procedure

product, unlesJ such product has been tested 

1n accordance with such test pr_ocedure and 

15Uch rep~taUon fairly d!scloses the re- sults o! 15Uch testing. 

In order to ellmlnate the problems 

discussed above associated with a general sampling provision, § 430.23 has 

been reserved in the final test proce- dures, and sampling requirements whlch 

apply onJy !or purposes of advertising have been reorganized into § 430.24. Ca> 

and· <b> o! the 1inal test procedures. sections 430.24 Ca> and Cb> are similar 

to proposed § 430.23 Ca> and Cb>. but 

contain several revisions. Most notably. the units tested are required to be rep- resentative o! production units or actual production units. This change is intended to reduce the burden which 

might be caused by requiring post-pro- duction rating o! basic models in every instance o! testing pursuant to section 

323Cc> o!theAct. 

Until a labellng rule has been implemented pursuant to section 324, 

manufacturers are not required to test 

unless they choose to make representa- tions regarding a measure of energy consumption identified in or based uPOil 

section 430.22 <a> and Cb). It should also 

be emphasized that the test p1ocedures prescribed today apply only to the initial rating o! a basic model. 

In addition, certain technlcal changes have been made in sampling language. Speclfically, there is to be 95 percent confidence that the true mean of any 

measure of the bask model lies within 

FEDERAL REGISTER, VOL 42, NO. 171-WEDNESDAY, SEPTEMl!Ell 14, 1977 
46142 RULES AND REGULATIONS 

±10 percent of the mean of such meas- switch is. in the same position as sel; at 

ure of the sample. Comments pertaining the factory is preferable to a. "standard

gested that a. sampling provision should been adopted~ A "cycle':_ refers to conrefer to the estimate of the mean rather tinuous operation of,a unit for a period than to the true mean. FEA has con- of 24 hours. However, test data may be

day is more technically correct' because hour period as specified in BRF-2-

the statistical measures "estimate of the ECFI'-1975. • 

mean" and "mean of the sample" are 

generally considered to be identical. The 

final te$t procedures for room air conditioners and dishwashers used l::oth these 

terms in a manner that could be confusing, and the language prescribed today is intended to eliminate this pos- · sibillty of confusion. 

a. PRODUCTS COVERED BY THE FINAL TEST 

PROCEDURES 

Some comments suggested that a few 

products cannot be tested satisfactorily using the proposed test procedures. FEA 

ls prepared to amend the test procedures 

as new products or new design features 

may require. No specific details have 

been provided, however, to justify any such amendments of the proposed test 

procedures at this time. 

One commenter specifically stated that 

compact refrigerators could not be tested 

accurately using the proposed test pro- cedures. No parti~ular feature of compact refrigerators was cited, however, 

which would render the test procedures inappropriate for testing these units. 

9. AMBIENT TEMPERATURES 

It was suggested that the test proce- dures be amended to specify that tests 

be conducted at an ambient temperature of 104° F. Although such a test would 

provide a. useful performance criterion, 

the change from the currently specified ambient temperature of 90° F. would 

not more accurately reflect energy emciency. Therefore, this suggestion 'was 

not adopted. 

10. NORMAL CYCLE 

Several comments suggested that the 

use of the word "normal" in the term 

"normal cycle" implied that that cycle 

was the usual cycle or the cycle expected to be used most often. CQIDmenters therefore took exception to the 

definition of "normal cycle" which stated 

that any anti-sweat heater switch would 

be 1n the highest energy consuming posi- tion during this cycle. The term "standard cycle" was offered as a substitute. 

FEA has adopted this change. Suggestions were also made to specify 

a. "standard cycle-maximwn" and a. 

"standard cycle-mlnimwn." FEA wishes 

to encourage maximwn use of energy- saving devices such as anti-sweat heaters. Evidence was elicited during the 

public comment period which indicated 

that anti-sweat heater switches tend to 

remain in the position set at the factory. In order to encourage manufacturers to ship refrigeration products with 

the anti-sweat heater switch in the lowest energy co~uming position, FEA has 

determined that a. cycle ill which the 

.11. CORRELA'rIVE TEST PROCEDURES 

. Several comments indicated that correlative methods have been developed by manufacturers of refrigeration products which yield virtually the same results as 

those obtained through the test proce- dures prescribed today. At this time FEA 

has not made a decision on the feasibility of allowing correlative testing. If additional data are submitted by individual 

manufacturers, FEA will examine the 

possibility of using correlative testing and will determine whether the Act 

would permit such methods to be used in 

lieu of the prescribed test procedures. 

12. MISCELLANEOUS 

After careful consideration of all the 

comments and further consultation with 

NBS and FTC, FEA has incorporated in 

the final rule some minor changes that 

were not discussed above. 

C. REGULATIONS PRESCRIBEil 

1. TEST PROCEDURES 

The test procedtires for electric refrigerators, electric refrigerator-freezers, and freezers prescribed today are 

included in Subpart B and are substantially the same as those proposed, with 

the exception of the changes discussed 

above. As with t,he proposal procedures, the test methodology incorporates the 

a!)proach contained in the Association 

of Home Appliance ManUfacturers 

(AHAM) Standard HRF-2-ECFT-1975 

for measuring average energy conswnp- tion per cycle type, and the American 

National Standard <ANS> B38.l-1970 

for measuring net refrigerated volwne. 

For purposes' of FEA's program, the incorporated standards remain applicable 

as presently written regerdless of any subsequent amendment of the ANS or 

AHAM Standard, until further amendment by FEA. 

Under the requirements of section 

32(c) of the Federal Energy Administration Act of 1974 <15' u.s.c. 761 et. seq.) 

as amended· by section 9 of the Federal 

Energy Administration Authorization 

Act Of 1977 <Pub. L. 95-70)' the Administrator of FEA is to consult with the 

Attorney General and the Chairman of 

the Federal Trade Commission concerning the· impact on competition of any rules prescribed by FEA which utillze or 

incorporate any commercial standards. 

The Administrator has transmitted 

copies of the test procedures for electric 

refrigerators, electric refrigerator-freezers, and freezers, which incorporate the 

above-mentioned commercial standards, 

to the Attorney General and the Chairman of the Federal Trade Commission 

for their comments concerning the ithpact ot such standards on competition, in accordance with section 32 <c> . Neither 

omcial has any comments, nor do they reoommend against the incorporation or 

use of these commercial standards in tho 

final test procedures for electric refrtg .. erators, electric refrigerator-freezers, 

and freezers. 

2. GENERAL :PROVISIONS 

Also prescribed today are defin1t.1ons 

of "electric refrigerator," "electric refrigerator-freezer," "freezer," "refriger- ator," and "refrigerator-freezer." Tho 

definition of the term "basic model" for 

refrigerators and refrigerator-freezers, and for freezers, has been added. Somo 

of these definitions were previously pro• posed in Subpart A (41 FR 19980, May 14, 1976; 42 FR 21588, April 27, 1977), 

Comments which were received regard .. ing these definitions, and the issues 

which they raised, have been discussed 

earlier iI1 this notice. 

3. APPLICATION OF TEST PROCEDURES 

As discussed previously, the final t~st 

procedures prescribed today must be ap- plied before representations regarding a 

measure of energy conswnption can b€l 

made. Because the purposes and needs 

of the different elements of the appliance 

program <e.g., labeling, targets> vary, application of the standard test methodology prescribed today may difier 1n 

some respects for each program element. 

It is expected that instructions on how 

to apply the standard test methodology 

to these other elements of the appliance 

program will be proposed for comment 

in the near future. 

The requirements of § 430.24 (a) and 

<b> of the final regulations apply until 

such time as final labeling requirements for a particular measure of energy conswnption and the associated test pro- cedure application provision are pre- scribed. After that time, all representa- tions regarding a measure of energy conswnption covered by a labeling rule 

must be the same as represented on the 

label. 

D. UNIT COSTS OF ENERGY 

Under section 323(b> (2) of the Act, 

FEA is to provide manufacturers information as to the representative average unit costs of energy. ThJs informa· 

tion was provided by notice issued July 11, 1977 C42 FR 36549, July 15, 1977), 

E. PREEMP'.l'ION 

Today's rulemaking prescribing final 

test procedures for electric. refrigerators, electric refrigerator-freezers, and freezers supersedes;any State regulation to 

the extent required by section 327 of 

the Act. Pursuant to section 327, all 

State regulations which provide for the 

disclosure of information with respect to 

any measure of energy consumption of 

electric refrigerators, electric refrigera- tor-freezers, or freezers, or which pro- vide for any energy emciency standard 

or similar requirement with respect to 

energy eiflciency or energy use of electric refrigerators, electric refrigern.tor- freezers, or freezers, must now employFEDERAL REGISTER', VOL 42, NO. 178-WEDNESDAY, SEPTEMBER 14, 1977 
test procedures identical to those specified in today's :final rule.

Polley and Conservation Act (Act> <Pub. 

L. 94-163). Clothes dryer test procedures were proposed by notice issued April 21, 

1977 (42 FR 21589, Aprll 27, 1977>, which 

solicited oral and written comments from 

interested persons, and a. public hearing on the proposed test procedures was held on June 13, 1977. The definitions of 

"electric clothes dryer" e.nd "gas clothes

Comments were received from indush'y, consumers, and a federal agency. 

Most or the comments were dlrected 

toward technlcal areas or the proposed 

test procedures, although some of the 

comments were specifically directed tov.ard the in!ormation that was to be 

placed on the IabeL Tne comments which were directly concerned with the content 

o! the label were more applicable to the 

labeling program under section 324 of 

the Act~ rather than to the prescription 

of flna1 test procedures, and were therefore forwarded to the Federal Txade 

Commls:3ion for consideration in developing labeling rules applicable to clothes 

dryer.;. Tne major issues raised by the 

c:Dmments on the proposed test procedures are discussed below. 

1. BASIC MODEL DEFINllION 

One manufacturer commented on the 

proposed definition for the "basic model'' 

o! clothes dryers in § 430.2 and suggested that the definition be broadened 

to provide that all similar models which consume an equivalent amount of energy 

when tested according to the proposed 

test procedures constitute the same basic 

model. In particular, it was recommended that the definition incorporate 

the idea that "styling difrerences. convenience :features, components and functions whibh do not alter energy usage, 

do not constitute additional 'basic models' and require testing thereof." 

In response to thls comment FEA has 

modlfled the proposed definition for the 

"basic model" of clothes dryers to clarify 

that a. slngle basic model includes units 

with any variety of dil!erent physical or·
