Standard Specification for Push-Fit Crosslinked Polyethylene (PEX) Mechanical Fittings for Crosslinked Polyethylene (PEX) Tubing
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.
SCOPE
1.1 This specification covers crosslinked polyethylene (PEX) push-fit mechanical fittings for use with crosslinked polyethylene (PEX) tubing in 1/2 , 3/4 , 1 and 1 1/4 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, 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
