1.1 This specification covers plastic insert fittings for polybutylene (PB) plastic tubing. These fittings are intended for use in 100-psi (6.9-MPa) cold- and hot-water distribution systems operating at temperatures up to and including 180°F (82°C). Included are the requirements for materials, workmanship, burst pressure, sustained pressure, temperature cycling tests, and markings to be used on the fittings. 1.2 The values stated in inch-pound units are to be regarded as the standard. The SI values stated in parentheses are provided for information purposes. 1.3 The following safety hazards caveat pertains only to the test method portion, Section 7, 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 and health practices and determine the applicability of regulatory limitations prior to use.
