This site has been established for applicant and enrolled laboratories in the Efficiency of Electric Motors (EEM) Laboratory Accreditation Program (LAP). On this site you will find important program information and links to documents required for successful participation in the program.

Program Description

The Efficiency of Electric Motors (EEM) laboratory accreditation program was originally developed at the request of the National Electrical Manufacturers Association (NEMA) to assist the electric motor industry in complying with the statutory requirements for electric motors in Section 431.36(a) of Title 10, Code of Federal Regulations (CFR) Part 431 (10 CFR Part 431). NVLAP coordinated the development of the EEM program with NEMA and the Department of Energy (DOE).

For information on the requirements of accreditation see NIST Handbook 150 which contains the general requirements for accreditation of laboratories. In addition, NIST Handbook 150-10 contains specific requirements for laboratories testing motors for energy efficiency.

Proficiency Testing Requirements

Periodically, NVLAP initiates interlaboratory proficiency testing for motors. The final report for Round 2 was released in October of 2012. The next round is expected to start in the fall of 2013 and cover small motors. The approximate cost is $1,000 US and laboratories with these types of testing on their scopes will be notified and invoiced when the round begins.

Frequently Asked Questions (FAQs)

Q: How much does accreditation cost?

A: Motors laboratories in the United States that are scheduled for an on-site assessment pay a fixed on-site assessment fee that is in addition to the administrative/technical support fee and any proficiency testing fees. Additional information about fees for accreditation is published on the NVLAP Fee Structure page of the NVLAP website.

Laboratories located outside of the United States: Non-U.S. laboratories pay actual expenses for assessments and will be invoiced the full cost of the assessment shortly after submitting the application.

Seeking motors assessor

NVLAP is seeking a motors assessor for its Efficiency of Electric Motors program. Applicants must have laboratory experience with IEEE standards 112 and 114, CSA C390 and C747, and IEC 60034-2-1. Experience as a management system assessor or auditor and knowledge of ISO/IEC 17025 is preferred. Position is contracted and requires domestic and international travel. If interested, please contact Timothy Rasinski, program manager.

Small Motors Accreditation Available

NIST Handbook 150-10 has been revised to include requirements for accreditation to IEEE 114-2010, Test Procedure for Single-Phase Induction Motors, and CSA 747-2009, Energy Efficiency Test Methods for Small Motors. The NIST Handbook 150-10 Checklist has also been revised. Accreditation to these new standards is optional for currently accredited laboratories. Laboratories may apply for accreditation to these standards by contacting the NVLAP program manager. Accredited laboratories will be required to submit documentation for review to have these methods added to their scopes or may wait until the next renewal assessment. Laboratories not accredited must apply for accreditation and undergo an assessment as a new laboratory.

Round Three of Proficiency Testing

Round three of motors proficiency testing is expected to support small motors accreditation. Provided sufficient laboratories apply for small motors accreditation, we expect to send motors out to the first laboratories in the fall of 2013. We have applied to the Department of Energy for financial assistance to defray the cost of the program.
