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
4、 and CPVC plastic pipe, and requirements and test meth-ods for materials, workmanship, dimensions, sustainedpressure, burst pressure, flattening, and extrusion quality.Methods of marking are also given.NOTE 1The CPVC pipe covered by this specification was coveredpreviously in Specification D2241.NOT
5、E 2The sustained and burst pressure test requirements 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 specifica
6、tion are intendedfor use with the distribution of pressurized 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
7、of their products.Consult with specific product/component manufacturers fortheir specific testing procedures prior to pneumatic testing.NOTE 3Pressurized (compressed) air or other compressed gasescontain large amounts of stored energy which present serious safteyhazards should a system fail for any

Thesenotes and footnotes (excluding those in tables and figures) shallnot be considered as requirements of the specification.1.4 The values stated in either SI units or inch-pound
9、 unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other.

22、imension ratio, hydrostaticdesign stress, and pressure rating:2 S/P 5 R 2 1or2S/P 5Do/t!2 1where:S = hydrostatic design stress, psi MPa,P = pressure rating, psi kPa,Do= average outside diameter, in. mmt = minimum wall thickness, in. mm, andR = standard thermoplastic pipe dimension ratio (Dot forCPVC
23、 pipe), also known as SDR.3.2.4 standard thermoplastic pipe dimension ratio (SDR)the standard thermoplastic pipe dimension ratio (SDR) is theratio of pipe diameter to wall thickness. For CPVC pipe it iscalculated by dividing the average outside diameter of the pipein millimetres or in inches by the
24、minimum wall thickness inmillimetres or in inches. If the wall thickness calculated by thisformula is less than 0.060 in. 1.52 mm, it shall be arbitrarilyincreased to 0.060 in. 1.52 mm.

26、 0.7 MPa with any decimal figures dropped.When the design stress code contains less than two figures, acipher shall be used before the number.
