Do most electronic components that are labeled as Class I Div 2 meet the ANSI/ISA 12.12.01-2000 specification? I know that ANSI/ISA 12.12.01-2000 is the Non-Incendive Component specification. Does UL, for example, always use the ANSI/ISA 12.12.01-2000 spec to test electronic equipment for suitability in CID2 areas, or only for equipment that is specifically trying to use the non-incendive component protection technique?
