1.1 This specification covers chlorinated poly(vinyl chlo-ride) (CPVC) pipe made in standard thermoplastic pipe dimen-sion ratios and pressure rated for water (see Appendix).Included are criteria for classifying CPVC plastic pipe mate-rials and CPVC plastic pipe, and requirements and test meth-ods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening, and extrusion quality.Methods of marking are also given.
N OTE 1—The CPVC pipe covered by this specification was covered previously in Specification D2241.
N OTE 2—The sustained and burst pressure test requirements and the pressure ratings in theAppendix are calculated from stress values obtained from tests made on pipe 2 in. (50 mm) and smaller. However, tests on larger pipe have shown these stress values to be valid.
