This specification covers crosslinked polyethylene (PEX) pipe that is outside diameter controlled in metric pipe sizes (DN 16 to 1000) and inch pipe sizes (NPS 3 to 54), and pressure rated (see Appendix X1) using the MRS rating system. This Specification is intended for PEX pipe made by various processes, as long as the PEX pipe made by that process meets all the requirements of this Specification. Included are requirements and test methods for material, workmanship, UV protection, dimensions, hydrostatic sustained pressure, environmental stress cracking, stabilizer functionality, bent-pipe hydrostatic pressure, oxidative stability in potable chlorinated water, minimum operating temperature, degree of crosslinking, and hydrostatic burst pressure. Requirements for pipe markings are also given. The pipe covered by this specification is intended for pressure piping applications such as, industrial and general-purpose pipelines, potable water pipelines, fire – extinguishing pipelines, oil and gas producing applications to convey fluids such as oil, dry or wet gas, gas gathering, multiphase fluids, and non-potable oilfield water, and chemical pipelines. It is not intended for municipal natural gas distribution...
