1 Scope 1.1 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…

1 Scope 1.1 This Standard specifies requirements for crosslinked polyethylene (PEX) tubing systems that comprise tubing and fittings. Tubing covered by this Standard is made in Standard Dimensional Ratio 9 (SDR 9). Systems are pressure rated at three temperatures: 1105 kPa at 23 °C, 690 kPa at 82 °C, and 550 kPa at 93 °C, with a maximum working pressure of 690 kPa at 82 °C. Systems are…

1 Scope 1.1 This Standard covers chlorinated polyvinylchloride (CPVC) pipe, tubing, and fittings in the following sizes and uses: a) standard dimension ratio 11 (SDR 11), and Schedules 40 and 80 pipe in pipe sizes whose dimension ratio does not exceed 11, for use in hot- and cold-water distribution systems at a maximum working pressure of 690 kPa and a maximum working temperature of 82 °C;…

1 Scope 1.1 This Standard covers polyethylene/aluminum/polyethylene (PE-AL-PE) macrocomposite pipe consisting of a welded aluminum tube laminated by a melt adhesive to layers of polyethylene (PE) inside and outside the aluminum tube. The pipes covered in this Standard are pressure rated for 1380 kPa at 23 °C, 1035 kPa at 60 °C, or 690 kPa at 82 °C. Systems are intended for use in potable water…

1 Scope 1.1 This Standard covers crosslinked polyethylene/aluminum/crosslinked polyethylene (PEX-AL-PEX) macrocomposite pipe consisting of a welded aluminum (AL) tube laminated by a melt adhesive to layers of crosslinked polyethylene (PEX) inside and outside the aluminum tube. This Standard also covers fittings (connectors) for use with PEX-AL-PEX pipe. The pipes covered in this Standard are…

1 Scope 1.1 This Standard specifies requirements for polyethylene of raised temperature (PE-RT) tubing systems that comprise tubing and fittings. Tubing covered by this Standard is made in Standard Dimensional Ratio 9 (SDR 9). Systems are pressure rated at two temperatures: 1105 kPa at 23 °C and 690 kPa at 82 °C. Systems are intended for use in potable water distribution systems or other…

1 Scope 1.1 General 1.1.1 This Standard applies to occupational diving operations conducted in connection with all types of work and employment, and describes the requirements for occupational safety. Note: It is recognized that certain underwater tasks might require specialized standards of practice and/or operational techniques that differ from the requirements of this Standard yet may be…

1 Scope 1.1 This Standard covers polyethylene (PE) pipe, tubing, and fittings for use in potable cold water supply services or other applications such as water-based ground source geothermal systems. 1.2 This Standard specifies requirements for materials, quality of work, dimensions, sustained pressure, environmental stress cracking, and markings. 1.3 In this Standard, “shall” is used to…

1 Scope 1.1 This Standard covers rigid polyvinylchloride (PVC) injection-moulded fittings that have gasketed joints and are intended for use in pressure applications such as water mains, water service piping, process piping, and fire lines. Fittings covered by this Standard are suitable for use with PVC pipes having outside diameter dimensions of cast iron pipe. Only one pressure rating, 1620…
