CAN3-B137.4-M86

Applies to polyethylene pipe, tubing and fittings for use in gas mains and services including gathering, transmission, and distribution application, which carry fuel gases containing not more than 1% of aromatic hydrocarbons. It also applies to all types of fittings and connections used in a 'plastic' gas pipe system including plastic-to-metal transition fittings, plastic fittings such as elbows, tees, end caps, valves etc., and clamps and couplings. The standard establishes the manufacturing and testing requirements necessary for ensuring that the polyethylene compound, pipe and fittings are of a level of quality acceptable for use in a gas distribution system.
