Relevant standards. Vinyl electrical products meet or exceed the stringent requirements set by various standards organizations for fire, physical and electrical performance, including Underwriters' Laboratories (UL), the National Fire Protection Association (NFPA), the International Organization for Standardization (ISO), the International Electrotechnical Commission (IEC), and CSA International (CSA). More information on the applicable standards governing wire and cable constructions is available from these organizations, and the presence of vinyl in these products does not effect the applicable standards.
Code information. Vinyl electrical products are accepted by all of the model code organizations, including the Southern Building Code Congress International (SBCCI), the Building Officials and Code Administrators International (BOCA), and the International Conference of Building Officials (ICBO). The most significant code regulating electrical products in which vinyl is used is the National Fire Protection Association's (NFPA) National Electrical Code (NEC). In many cases, vinyl is the only insulation material that can be used in order for a product to meet NEC regulations and at reasonable cost.
