This specification establishes the requirements for polypropylene (PP) piping system components such as pipe, fittings, valves, and manifolds used in water service lines, hot-and-cold water distribution, hydronic heating, and irrigation systems to transport industrial process fluids, effluents, slurries, municipal sewage, etc. The piping system components covered here are made to metric sizes and IPS schedule 80 sizes, and pressure rated for water service and distribution supply. When tested according to the procedures provided herein, the piping components shall adhere to specified requirements for workmanship, dimensions, longitudinal reversion, melt flow rate, impact resistance, thermal stability and oxidative induction time (OIT), hydrostatic pressure, thermocycling, and oxidative stability in potable chlorinated water.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification establishes requirements for polypropylene (PP) piping system components made to metric sizes and IPS schedule 80 sizes, and pressure rated for water service and distribution supply (see Appendix X1). Included are criteria for materials, workmanship, dimensions and tolerances, product tests, and marking for polypropylene (PP) piping system components such as pipe, fittings, valves, and manifolds.

1.2 The components governed by this specification shall be permitted for use in water service lines, hot-and-cold water distribution, hydronic heating, and irrigation systems.

1.3 The pipe and fittings produced under this specification shall be permitted to be used to transport industrial process fluids, effluents, slurries, municipal sewage, etc. The user shall consult the manufacturer to determine whether the material being transported is compatible with the polypropylene piping system and will not affect the service life beyond limits acceptable to the user.

1.4 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
