1.1”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, stabilizer functionality, bent-pipe hydrostatic pressure, chemical resistance, minimum operating temperature, degree of crosslinking, squeeze-off, and hydrostatic burst pressure. Requirements for pipe markings are also given. The pipe covered by this specification is intended for natural gas distribution.
