This standard describes Cross-linked Polyethelyene (PEX) pressure pipe made from material having a standard PEX material designation code of PEX 1006 in ASTM F876 for use as underground water service lines in sizes A1/2 in. (12mm) through 3 in. (76mm) that conform to a standard dimension ratio of SDR9.

Included in this standard are criteria for classifying PEX plastic pipe materials, a system of nomenclature, requirements, and test methods for materials and pipe. Methods of marking are given. Design, installation, and application considerations are discussed.

The purpose of this standard is to provide the requirements for materials, design, testing, inspection, and shipping of PEX pipe for use as service lines in the construction of underground water distribution systems. This standard can be referenced for purchasing and receiving PEX pressure pipe and as a guide for manufacturing PEX pressure pipe.
