This Standard describes the requirements and test methods for the materials, dimensions, workmanship, pipe stiffness, quality control, jointing systems, and marking for corrugated polyethylene (PE) storm and sanitary sewer pipe and fittings with a smooth interior. This profile wall pipe consists of an outer corrugated wall fused to a smooth inner wall, with sizes based on controlled inside diameter. Notes: (1) Pipe and fittings produced to meet the requirements of this Standard should be installed in accordance with ASTM Standard D2321-83a, or in accordance with the manufacturer's suggested practice. (2) Industrial waste disposal lines should be installed only with the specific approval of the regulatory authority since chemicals not commonly found in drains and sewers may be encountered, as well as temperatures greater than 60?.
