Abstract
This specification covers crosslinked polyethylene (PEX) push-fit mechanical fittings for use with crosslinked polyethylene (PEX) tubing that meet the requirements of Specification F876. These fittings are intended for use in residential and commercial, hot and cold, potable water distribution systems as well as hydronic heating, including under-floor heating systems. Included are the requirements for materials, workmanship, dimensions, performance, and markings to be used on the fittings.
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 covers crosslinked polyethylene (PEX) push-fit mechanical fittings for use with crosslinked polyethylene (PEX) tubing in ½, ¾, 1 and 1 ¼ in. nominal diameters that meet the requirements of Specification F876. These fittings are intended for use in residential and commercial, hot and cold, potable water distribution systems as well as hydronic heating, including under-floor heating systems, up to and including 100 psig (6.90 bar) and 180°F (82°C). Included are the requirements for materials, workmanship, dimensions, performance, and markings to be used on the fittings.
1.2 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 text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.
1.4 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.
