This specification covers the requirements and methods of test for corrugated polyethylene (PE) pipe, couplings, and fittings for use in subsurface drainage systems, storm sewers, and in surface drainage (culverts), where soil support is given to the pipe’s flexible walls in all applications.

Nominal sizes of 75 to 250 mm (3 to 10 in.) are included.

Materials, workmanship, dimensions, pipe stiffness, environmental stress-crack resistance, perforations, joining systems, brittleness, and form of markings are specified.

Note—When PE pipe is to be used in locations where the ends may be exposed, consideration should be given to combustibility of the PE and the deteriorating effects of prolonged exposure to ultraviolet radiation.
