scope:

This standard describes polyethylene (PE) pressure pipe and tubing made from material having standard PE code designation PE4710* and intended for use in potable water, reclaimed water, and wastewater service. PE pipe ranges in nominal size from ³/₄ in. (19 mm)^† through 3 in. (76 mm) and conforms to the outside-diameter (OD) dimensions of iron pipe size (IPS). PE tubing ranges in size from ³/₄ in. (19 mm) through 2 in. (51 mm) and conforms to the OD dimensions of copper tube size (CTS). 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 also given.

Purpose

The purpose of this standard is to provide the requirements for materials, testing, inspection, and shipping of PE pipe (³/₄ in. [19 mm] through 3 in. [76 mm]) and PE tubing (¾ in. [19 mm] through 2 in. [51 mm]) for potable water, wastewater, and reclaimed water systems.

^* Earlier editions of ANSI/AWWA C901 included other PE material designations. For removed designations, refer to previous editions of ANSI/AWWA C901, ASTM D3350, PPI (Plastics Pipe Institute) TR-3, and PPI TR-4.
