Draft Scope/Description:

1.1 General

This Standard covers chlorinated polyvinylchloride (CPVC) pipe, tubing, and fittings in the following sizes and uses:

a) 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; and

b) SDR 13.5 and SDR 21 for use only in cold-water distribution and water service systems at a maximum working pressure of 2170 kPa and 1380 kPa, respectively, and a maximum working temperature of 23 °C.

Note: This Standard does not specify requirements for venting of combustion gases. In Canada, ULC S636 specifies testing and marking requirements for pipe, fittings, and accessories intended for venting of combustion gases. In the United States, UL 1738 specifies testing and marking requirements for pipe, fittings, and accessories intended for venting of combustion gases.

1.2 Requirements

This Standard specifies requirements for materials, quality of work, dimensions and tolerances, hydrostatic sustained pressure strength, thermocycling resistance, solvent cement, joint strength, and markings.
