TABLE I1INDUSTRY STANDARDS CURRENTLY INCORPORATED BY REFERENCE FOR SMALL ELECTRIC MOTORS
Equipment description
Industry test procedure
Single-phase small electric motors
Polyphase small electric motors less than or equal to 1 horsepower
Polyphase small electric motors greater than 1 horsepower

More recently, DOE published a request for information pertaining to the test procedures for small electric motors and electric motors in July 2017. 82 FR
35468 July 31, 2017 July 2017 RFI.
In the July 2017 RFI, DOE solicited public comments, data, and information on all aspects of, and any issues or problems with, the existing DOE test procedure for small electric motors, including on any needed updates or revisions. DOE also discussed potential categories of electric motors as defined at 10 CFR 431.12 that may be considered in future DOE test procedures. 82 FR 3547035474. At the request of commenters, DOE extended
IEEE 1142010, CSA C74709.
IEEE 1122004 Test Method A, CSA C74709.
IEEE 1122004 Test Method B, CSA C39010.

the comment period for the July 2017
RFI in a notice published on August 30, 2017. 82 FR 41179.
Separate from the July 2017 RFI, NEMA and Underwriter Laboratories UL independently submitted written petitions requesting that certain portions of International Electrotechnical Commission IEC
6003421:2014 be adopted as a permitted alternative test method for small electric motors and electric motors.5 DOE published a notice of receipt of these petitions on November 2, 2017. 82 FR 50844 November 2017
notice of petition.
On April 23, 2019, DOE published a NOPR April 2019 NOPR responding
to the comments received to the July 2017 RFI and proposing to further clarify the test procedures for small electric motors and incorporate an additional industry test method, IEC
6003421:2014 industry test standard, for testing small electric motors and electric motors.6 84 FR 17004 April 23, 2019. The April 2019 NOPR also addressed the test procedures for electric motors in response to the November 2017 notice of petition. Id.
DOE received four comments in response to the April 2019 NOPR from the interested parties listed in Table I
2.

II. Synopsis of the Final Rule In this final rule, DOE is amending 10
CFR part 431 as follows:
1 Updating the referenced industry testing standard for measuring the energy efficiency of small electric motors and electric motors to its latest version, IEEE 1122017, IEEE Standard Test Procedure for Polyphase Induction Motors and Generators;

2 Incorporating by reference as an alternative test procedure for the measurement of energy efficiency in small electric motors and electric motors testing standard IEC 600342
1:2014, Standard methods for determining losses and efficiency from tests excluding machines for traction vehicles;
3 Adding definitions for rated load, rated output power, and breakdown torque of small electric
Organization type
motors based on NEMA MG 12016;
and 7
4 Specifying the frequency used for testing by defining rated frequency, and specify that manufacturers select the voltage used for testing by defining rated voltage.
Table II1 summarizes the test procedure amendments compared to the current test procedure as well as the reason for each change.

TABLE II1SYNOPSIS OF THE NOTICE OF TEST PROCEDURE
Current test procedure Incorporates by reference IEEE 112
2004 to measure full-load efficiency of polyphase small electric motors.

NOPR test procedure Proposed adding IEEE 1122017 as an alternative to IEEE 1122004.
The IEEE 1122017 version includes the following updates compared to IEEE 1122004:
1 Updates to certain requirements regarding measurement instrument selection and accuracy.

Achieves consistency with industry update to IEEE 1122017.
Addresses comments in response to the April 2019 NOPR that including both the 2004 and 2017 versions of IEEE 112 is unnecessary because they are equivalent. See section III.B.1 for further discussion.
