manufacturer will experience undue hardship. Id.
F. Test Procedure Costs and Impacts EPCA requires that test procedures prescribed by DOE not be unduly burdensome to conduct. 42 U.S.C.
6314a2. DOE is amending 1 the existing test procedure for small electric motors by clarifying the existing scope
and testing instructions, updating the reference to industry standard IEEE 112
to reference the 2017 version in place of the 2014 version, and permitting the use of IEC 6003421:2014 as an additional alternative test procedure; and 2 the existing test procedure for electric motors by permitting the use of IEC
6003421:2014 as an additional alternative and equivalent test
procedure. DOE has determined that the test procedures as amended by this final rule will not be unduly burdensome for manufacturers to conduct and instead will reduce test burden for manufacturers.
This final rule will result in a net cost savings to manufacturers, as summarized in Table III1 and Table III2.

Further discussion of the analyses of the cost impact of the test procedure amendments is presented in the following paragraphs.
1. Cost Impacts for Small Electric Motors The clarifications of the existing scope and test instructions will not impose any new requirements on manufacturers of regulated small electric motors. Instead, this final rule will provide manufacturers with greater certainty in the conduct of the test procedures, offer additional equivalent testing options, and do not increase test burden. Reference to IEEE 1122017 in place of IEEE 1122004 will not increase test burden or require new testing. As discussed, results under the 2017 version of IEEE 112 are equivalent to results from testing under the 2004
version. Manufacturers will be able to rely on data generated under the current test procedure. Additionally, the incorporation of IEC 6003421:2014 as an additional alternative test procedure further harmonizes DOEs test

procedures with current industry practice and international standards.
Permitting manufacturers to test according to IEC 6003421:2014
enables manufacturers who use IEC
6003421:2014 for business purposes for international markets, or to comply with regulatory requirements in other countries, to reduce the number of tests that they must perform by removing the need to conduct a test according to the CSA or IEEE methods 27 currently referenced in DOEs test procedure for small electric motors. As described in section III.B.2, NEMA and UL petitioned that certain portions of IEC test procedure 6003421:2014 be adopted as a permitted alternative test method for small electric motors and electric motors. UL further noted in its petition the increasing use of the IEC test procedure 6003421:2014 by the industry worldwide.
27 CSA 74709, CSA 39010, IEEE 1122017 per the amended reference under this final rule, or IEEE 1142010 depending on the category of small electric motor.

Recognizing that some, but not all, manufacturers already test their motors using IEC 6003421:2014, DOE as explained later in this section assumed that 10 percent 28 of small electric motor models sold in the U.S. that are tested with either the CSA or IEEE methods referenced in the Federal test procedure are also tested with the IEC 6003421
method.
To calculate the testing cost reduction associated with allowing the IEC 60034
21:2014 method for testing small electric motors, DOE estimated the number of motor models that would not have to be tested to both the amended DOE test procedure and the IEC test 28 NEMA and UL did not provide quantitative information regarding the number of small electric motors that are tested with either the CSA method or the IEEE method, and the IEC method, although NEMA commented that this is an increasing trend.
Based on a review of the market, only a small fraction of motors are designed for operation on 50
Hz and 60 Hz power indicating they are suitable for sale in both the U.S. and foreign markets, or use NEMA and IEC units of measure hp vs. kW and other designators. As noted, the U.S. electrical grid is operated at 60 Hz, while many other countries and regions e.g., Europe operate at 50 Hz.
