National Voluntary Laboratory Accreditation Program (NVLAP) Efficiency of Electric Motors



Timothy W. Rasinski


NIST Handbook 150-10 presents technical requirements and guidance for the accreditation of laboratories under the National Voluntary Laboratory Accreditation Program (NVLAP) Efficiency of Electric Motors program. It is intended for information and use by accredited laboratories, laboratories seeking accreditation, laboratory accreditation systems, users of laboratory services, and others needing information on the requirements for accreditation under this program. The 2013 edition of NIST Handbook 150-10 incorporates the following changes made with respect to the previous edition: all references to applicable international guides, national and international standards, and U.S. regulations have been updated; updated federal regulations that cover requirements for determining the efficiency of polyphase electric motors and small electric motors have been included. The requirements of NIST Handbook 150, the interpretations and specific requirements in NIST Handbook 150-10, and the requirements in program-specific checklists (if applicable) must be combined to produce the criteria for accreditation in the NVLAP Efficiency of Electric Motors program.
