The National Electrical Manufacturers Association (NEMA) published American National Standard for Lighting Systems—Non-Active Mode Power Measurement ANSI C137.63103-2021.
This newly published standard adopts IEC 63103, ed1.0 (2020-07) as a nationally acknowledged international standard with deviations. It provides manufacturers and testing laboratories with a harmonized way of determining standby power consumption for lighting systems, eliminating duplicative testing and streamlining global commerce.
"This regional adoption of an IEC standard benefits the industry by closely aligning lighting system standby power measurement with our international counterparts," said Ernesto Mendoza, Senior Manager, Signify North America Corporation, and C137 Workgroup Chair.ANSI C137.63103-2021
