3、as editorially revised in September 2013.1. Scope*1.1 This specification covers chlorinated poly(vinyl chloride) (CPVC) pipe made in Schedule 40 and 80 sizes and pressure-ratedfor water (see appendix). Included are criteria for classifying CPVC plastic pipe materials and CPVC plastic pipe, a system
4、ofnomenclature for CPVC plastic pipe, and requirements and test methods 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 covered previously in Specific
5、ation D1785.NOTE 2The sustained and burst pressure test requirements, and the pressure ratings in the appendix, are calculated from stress values obtained fromtests made on pipe 2 in. 50 mm and smaller. However, tests on larger pipe have shown these stress values to be valid.1.2 The products covered
6、 by this specification are intended for use with the distribution of pressurized liquids only, which arechemically compatible with the piping materials. Due to inherent hazards associated with testing components and systems withcompressed air or other compressed gases some manufacturers do not allow
7、 pneumatic testing of their products. Consult withspecific product/component manufacturers for their specific testing procedures prior to pneumatic testing.NOTE 3Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which present serious saftey hazards shoulda
8、 system fail for any reason.1.3 The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notesand footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.1.4 The values stated in either
9、 SI units or inch-pound units are to be regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.5 The followi
