3、ember 2013.1.Scope*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
4、test meth-ods for materials,workmanship,dimensions,sustainedpressure,burst pressure,flattening,and extrusion quality.Methods of marking are also given.NOTE1The CPVC pipe covered by this specification was coveredpreviously in Specification D2241.NOTE2The sustained and burst pressure test requirements
5、 and thepressure ratings in theAppendix are calculated from stress values obtainedfrom tests made on pipe 2 in.(50 mm)and smaller.However,tests onlarger pipe have shown these stress values to be valid.1.2 The products covered by this specification are intendedfor use with the distribution of pressur
6、ized liquids only,whichare chemically compatible with the piping materials.Due toinherent hazards associated with testing components and sys-tems with compressed air or other compressed gases somemanufacturers do not allow pneumatic testing of their products.Consult with specific product/component m
7、anufacturers fortheir specific testing procedures prior to pneumatic testing.NOTE3Pressurized(compressed)air or other compressed gasescontain large amounts of stored energy which present serious safteyhazards should a system fail for any reason.1.3 The text of this specification references notes,foo
