AWWA C901-08

This standard describes minimum requirements for PE pressure pipe and tubing made from material having standard PE code designations PE 2606, PE 2706, PE 2708, PE 3608, PE 3708, PE 3710, PE 4608, PE 4708, and PE 4710 and intended for use in potable water, reclaimed water, and wastewater service. 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 for 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 forward to this standard.
