Underwriters Laboratories Inc. (UL), a Northbrook, IL, U.S.-based product-safety testing organizations, announces that the U.S. Department of Energy (DOE) has recognized its Energy Verification Service Program for electric motors.
By April 28, 2003, all electric motor manufacturers are required to submit compliance documentation to the DOE declaring that their motors meet the energy-efficiency requirements contained in the DOE's Federal Register Notice, 10 CFR Part 431 dated Oct. 5, 1999. Manufacturers have two options to demonstrate compliance: use a third-party certification organization that is nationally recognized by the DOE or conduct testing at a National Voluntary Laboratory Accreditation Program (NVLAP) facility.
"UL's recent recognition from the DOE demonstrates our world-class ability to evaluate electric motors for energy efficiency," said Lenore Berman, UL's Primary Designated Engineer manager for Energy Verification.
UL says it can evaluate motors for safety and energy efficiency simultaneously. Motors that meet the requirements for safety and energy-efficiency are authorized to bear UL's combination Energy Verification Mark with the UL Listing or Component Recognition Mark. The testing organization says that as a result, electric motor manufacturers will be able to give their customers products with specified and verified efficiency ratings that comply with DOE provisions and the national safety standards.
The requirements set forth by the DOE apply to electric motors that are general-purpose, T-frame, single-speed, foot-mounted, polyphase, squirrel-cage induction motors with a NEMA Design A or B configuration. The motors range from 1-200 hp, are continuous duty rated, and operate on a 230/460 V, 60-Hz supply. If a motor doesn't fall into all of the above parameters, the regulation does not apply. In addition, special purpose and definite purpose motors are exempt.
