ASTM F2829/F2829M – Standard Specification for Metric- and Inch-Sized Fittings for Crosslinked Polyethylene (PEX) Pipe

1.1 This specification covers performance requirements, test methods, and marking requirements for metric- and inch-sized fittings for use with Specification F2788, 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.
