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.
