Energy Conservation Program: Test Procedures for Electric Motors and Small Electric Motors

This notice announces receipt and publishes petitions from the National Electrical Manufacturers Association (NEMA) and UL LLC (UL) requesting that the U.S. Department of Energy (DOE) incorporate the IEC 60034-2-1:2014 (2014) test methods 2-1-1A and 2-1-1B as alternative test methods in addition to the existing test methods referenced in its regulations for determining the energy efficiency of certain electric motors and small electric motors: Institute of Electrical and Electronics Engineers (IEEE) standards 112-2004 Method B (2004) and 114-2010 (2010); and Canadian Standards Association standards (CSA) C390-10 (2010) and C747-09 (2009). NEMA found IEC 60034-2-1:2014 Method 2-1-1B to be equivalent to IEEE 112-2004 Method B and CSA C390-10 UL testing found IEC 60034-2-1:2004 Method 2-1-1B results to be in close agreement with those of CSA C390-10, and noted that the respective methodologies of IEC 60034-2-1:2014 Method 2-1-1A and CSA C747 were also in accord. DOE solicits comments, data, and information concerning NEMA's and UL's petitions.
