CTL = Committee of Testing Laboratories See: http://www.iecee.org/ctl/aboutctl.htm "The Committee of Testing Laboratories is the technical branch of the IECEE and the biggest forum of technical experts representing 336 CB Testing Laboratories, located in 52 different Countries, and operating under the responsibility of the relevant National Certification Bodies (NCBs) members of the IECEE." CTL addresses interpretation and process problems and questions arising from IEC standards. CTL decisions apply to all labs that participate in the CB scheme, which is most of the world's safety certification houses.
