This standard describes polyethylene (PE) pressure pipe and tubing made from material having standard PE code designations PE 2406, PE 3406, and PE 3408 and primarily intended for use in the transportation of water and other liquids. Polyethylene pipe ranges in nominal size from 1/2 in. (13 mm) through 3 in. (76 mm) and conforms to the outside-diameter dimensions of iron pipe sizes (OD-based, IPS pipe) or to the inside-diameter dimensions of iron pipe sizes (ID-based, IPS pipe). Polyethylene tubing ranges in size from 1/2 in. (13 mm) through 2 in. (51 mm) and conforms to the outside-diameter dimensions of copper tubing. Included in this standard are criteria for classifying PE plastic pipe materials, a system of nomenclature for PE plastic pipe, and requirements and test methods for materials, pipe, and tubing. Methods of marking are given. Design, installation, and application considerations are discussed in the foreword to this standard. Major changes made to the standard in this revision include the following:
Sec. III.A., a note regarding purchaser requirement of certification to ANSI/NSF 61 has been added; and, revisions have been added in Sec. 4.2
