2、n, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification establishes requirements for polypro-pylene (PP) piping system components made to m

3、etric sizesand IPS schedule 80 sizes, and pressure rated for water serviceand distribution supply (see Appendix X1). Included arecriteria for materials, workmanship, dimensions and toler-ances, product tests, and marking for polypropylene (PP)piping system components such as pipe, fittings, valves,

4、andmanifolds.1.2 The components governed by this specification shall bepermitted for use in water service lines, hot-and-cold waterdistribution, hydronic heating, and irrigation systems.1.3 The pipe and fittings produced under this specificationshall be permitted to be used to transport industrial p

5、rocessfluids, effluents, slurries, municipal sewage, etc. The user shallconsult the manufacturer to determine whether the materialbeing transported is compatible with the polypropylene pipingsystem and will not affect the service life beyond limitsacceptable to the user.1.4 UnitsThe values stated in

6、 inch-pound units are to beregarded as standard. The values given in parentheses aremathematical conversions to SI units that are provided forinformation only and are not considered standard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It

7、is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory requirements prior to use.2.
