Scope

1.1 This specification establishes requirements for sulfone plastic insert fittings and copper crimp rings for three sizes (1⁄2, 3⁄4, and 1) of cross-linked polyethylene (PEX) tubing that meet the requirements for Specification F876 or F3253, and polyethylene of raised temperature (PE-RT) tubing that meet the requirements of Specification F2623. These fittings are intended for use in 100 psi (690 kPa) coldand 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. GO/NO-GO Crimp Gauges Appendix X1 1.4 The following precautionary caveat pertains only to the test method portions, Sections 11 and 12, of this specification. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
