Regulatory History

• Test Procedures: 

DOE’s current test procedures for the subject products are 

10 CFR part 430, subpart B, appendix N, for residential fuand boilers. These procedures include measures of energefficiency (e.g., annual fuel utilization efficiency (AFUE)), e

descriptors, annual fuel and electric energy consumption, annual operating cost. And, by virtue of recent amendme

test procedure also includes provisions to measure and inelectrical standby mode and off mode energy consumptio

• Energy Conservation Standards:

DOE set standards for these products in its recent Direct published in the Federal Register on June 27, 2011. This 

Final Rule sets minimum requirements for standby mode mode energy use in terms of measured wattages. (For exwatts for most furnaces and boilers effective May 1, 2013) 
Building Technologies Program 8 

Regulatory History -continued

– The Energy Independence and Security Act of 2007 (E

Directs DOE to incorporate a measure of standby mod

mode energy consumption into its test procedures. 

– EISA 2007 also directs DOE to integrate such energy 

consumption into the energy efficiency, energy consumother energy descriptor unless the Secretary determincurrent test procedures already fully account and incostandby mode and off mode energy consumption or suintegrated test procedure is technically infeasible. 

– In developing an amended test procedure, DOE must 

the most current versions of International ElectrotechnCommission (IEC) Standards 62301, “Household elecappliances–Measurement of standby power,” and IEC 62087, “Methods of measurement for the power consuaudio, video and related equipment.”

Review of EISA Amendments for Furnace and Boilers Test Procedures

• DOE met its test procedure obligations under EISA 2007require

residential furnaces and boilers through publication of a Final RuOctober 20, 2010. (75_FR 64621) 

– In completing this final rule, DOE determined that the test procedure

measurement and calculation provisions in order to account for elecmode and off mode energy use. Fossil-fuel standby mode and off muse was already integrated into the furnace and boiler test procedu

• For measurement of electrical standby mode and off mode watta

amended test procedure utilizes IEC Standard 62301with clarifickey clarification is that the existing test procedure specifications temperature and voltage shall apply in lieu of IEC Standard 6230provisions for these parameters.

• It is noted that these amendments referenced the first edition o

Standard 62301 for the electrical standby mode and off mode measurements. The first edition of IEC 62301was the most cur

of this industry standard at the time the final rule was issued. 
Building Technologies Program 10 

Second Edition of IEC 62301

• Since the time of the October 2010 final rule for furnaces 

boilers, IEC has finalized a second edition to the 62301 st

• DOE has reviewed the second edition of the IEC 62301an

found it to be superior to the first edition in a number of wa(Details of this review are outlined in the following slides)

• Consequently, DOE is proposing to incorporate IEC Stand

(Second Edition) in its entirety into the overall list of incorpreferences in DOE’s regulations at 10 CFR 430.3 and to c

applicable provisions of that standard in DOE’s test proceregulations for residential furnaces and boilers.

Details of DOE’s review of the Second Edition IEC 62301 Standard

DOE identified two areas of improvement

• Accuracy provisions, and• Specifications for stability
Building Technologies Program 12 

Details of DOE’s review of the Second Edition IEC 62301 Standard

Accuracy provision: • A more comprehensive specification of required accuracy 

provided in IEC Standard 62301 (Second Edition) that depupon the characteristics of the power being measured. Dbelieves that this revision provides more realistic accuracy provisions for a range of electricity consumption patterns, 

making the test method appropriate for the variety of electconsuming devices present in furnaces and boilers. 

• The new specification can be met by commercially-availab

equipment, whereas requirements in the first version may required specialized instrumentation that is not readily ava

ACCURACY PROVISION:

• Explaining further, the second edition specifies instrument 

based on the expected uncertainty. The uncertainty depenvalue termed the Maximum Current Ratio (MCR), which is of the Crest Factor to the Power Factor of the signal. e.g. 

signals with MCR’s less than 10, the allowed instrument uwould be 2 % at the 95 % confidence interval for power vagreater than 1.0 W. For measured power values less than the maximum permitted absolute uncertainty would be lesequal to 0.02 W at the 95 % confidence interval. 

• DOE believes both levels of uncertainty are sufficient to a

standby mode and off mode energy consumption of furnaboilers. 
Building Technologies Program 14 

Details of DOE review of Second

Edition IEC 62301 Standard (continued)

Stability: 

• IEC Standard 62301 (Second Edition) contains more deta

techniques to evaluate the stability of the power consump

measure the power consumption for loads with different scharacteristics. A longer observation period is prescribed second edition. For constant power modes, the test methospecified in the second edition matches that specified in th

edition. These techniques will result in more accurate meastandby energy consumption over a variety of operational characteristics that could be associated with the electrical components of furnaces and boilers. 

• The user is given a choice of measurement procedures, in

less burdensome methods such as direct meter reading mcertain clearly-described stability conditions are met. 
Building Technologies Program 15 

Details of DOE review of Second

Edition IEC 62301 Standard (continued)

Summary:• DOE believes that the changes incorporated in IEC S

62301 (Second Edition) would allow for use of less burdensome methods when appropriate and would eaccurate measures of standby energy consumption range of operating conditions that may be observed residential furnaces and boilers. 

• In addition, DOE has examined some common comm

available instrumentation for making these measureand DOE has determined that the specifications in thedition are more in line with the performance specificcommercially-available equipment.
