This specification details the physical and performance requirements, and the corresponding test methods, for the evaluation of crosslinked polyethylene (PEX) pipes that are outside diameter controlled, made in nominal pipe dimension ratios, and pressure rated for water at different temperatures. Crosslinked PEX pipes covered here shall be made from polyethylene compounds that have been crosslinked by peroxides, Azo compounds, or silane compounds in extrusion, or by electron beam after extrusion, and are primarily defined by means of three criteria, namely, nominal density, degree of crosslinking, and long-term strength tests. Sampled pipe specimens shall be tested for conformance with workmanship, dimension (out-of-roundness, outside diameter, and wall thickness), density, hydrostatic burst pressure, hydrostatic sustained pressure strength, excessive temperature-pressure capacity, environmental stress cracking, stabilizer functionality, bent-pipe hydrostatic sustained pressure strength, oxidative stability in potable chlorinated water, and degree of crosslinking requirements.
