ASTM F2829/F2829M-21

1.1?This specification covers performance requirements, test methods, and marking requirements for metric- and inch-sized fittings for use with Specification F2788/F2788M, F2905/F2905M, and F2968/F2968M PEX pipe. The following performance requirements are described for the fittings 73 ?F [23 ?C] hydrostatic strength, 176 ?F [80 ?C] hydrostatic strength, short-term internal pressure resistance, resistance to tensile loads, cohesive resistance for electrofusion fittings at both the minimum and maximum recommended temperatures, impact resistance for saddle fittings, and leak tightness and pull out tests for mechanical fittings. The metric- and inch-sized components covered by this specification are intended for the above-ground and buried pressure piping applications, such as industrial and general-purpose pipelines, potable water pipelines up to 140 ?F [60 ?C], fire extinguishing pipelines.

1.2?Crosslinking requirements for PEX pipe are found in Specifications F2788/F2788M, F2905/F2905M, and F2968/F2968M.

1.3?Requirements for materials, workmanship, and qualification testing performance are included.

1.4?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.

1.5?The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text the SI units are shown in brackets. The values stated in each system may not be exact equivalents: therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.6?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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7?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.
