1.1 This specification covers performance requirements, test methods, and marking requirements for metric- and inch-sized system components (electrofusion and mechanical fittings) when joined with metric- or inch-sized PEX pipe (Specification F2788) as a system, intended for use up to and including a maximum working temperature of 200°F [93°C ]. The following performance requirements are described for the fittings – 68°F [20°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 & general-purpose pipelines, potable water pipelines, and fire – extinguishing pipelines.
