1. Scope 1.1 This Standard covers performance testing of socket- and saddle-type polyethylene electrofusion fittings that are used to join polyethylene pipe where the heat source is an integral part of the fitting. Note: Fittings covered by this Standard are connected to an electrical power source during the fusion process. Power sources, cables, and electrical connections are covered by the Canadian Electrical Code, Parts I and II, as appropriate. 1.2 Electrofusion fittings are intended for use with polyethylene pipe that conforms to CSA Standard B137.4. 1.3 This Standard includes general requirements for materials, performance requirements, requirements for manufactured fittings, specimen preparation requirements, test methods, marking requirements, and quality of work requirements. Note: "Pipe" refers to pipe having IPS outside diameters. "Tubing" refers to pipe having copper tube size outside diameters. Where there are test requirements for pipe, they apply to both pipe and tubing. 1.4 The values given in SI (metric) units are the standard. The values in parentheses are for information only.
