This Standard covers socket- and saddle-type polyethylene (PE) electrofusion fittings that are used to join PE 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, Part I and Part II, as appropriate.
PE electrofusion fittings covered by this Standard are intended for use with PE pipe that complies with CSA B137.4.
This Standard specifies general requirements for materials, performance, manufactured fittings, specimen preparation, test methods, markings, and quality of work.
1) In this Standard, "pipe" refers to pipe having IPS outside diameters and "tubing" refers to pipe having copper tube outside diameters.
2) In this Standard, test requirements for pipe apply to both pipe and tubing.
In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard.
