This specification establishes requirements for sulfone plastic insert fittings utilizing a copper crimp ring for SDR9 cross-linked polyethylene (PEX) tubing for cold- and hot-water distribution systems. Material for fitting shall be molded from sulfone plastic. Molded part shall not crack, split, or shatter and be free of visible splay. Fittings shall be tested for performance requirements such as hydrostatic burst, hydrostatic sustained pressure strength, thermocycling, excessive temperature-pressure capability, dimensions, workmanship, finish, appearance, assembly, crimp joint, and insert crush test.
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.
1.1 This specification establishes requirements for sulfone plastic insert fittings and copper crimp rings for four sizes
(3/8, ½, and ¾ and 1) of cross-linked polyethylene (PEX) plastic tubing an polyethylene of raised temperature (PE-RT) tubing. These fittings are intended for use in 100 psi (690 kPa) cold- and hot-water distribution systems operating at temperatures up to and including 180°F (82°C). Included are the requirements for material, molded part properties, performance, workmanship, dimensions, and markings to be used on the fittings and rings.
1.2 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.
1.3 The following is an index of the appendix in this specification:
