This specification covers the general requirements and corresponding test methods for non-pressure (gravity flow) polyethylene (PE) pipes and fittings having interior liner with annular corrugated exterior wall profile, and whose inside diameters are 2 to 60 in. [50 to 1500 mm]. These pipes and fittings are suitable for underground use in subsurface and land drainage systems, which do not operate under surcharge pressure heads. Material requirements are specified for pipe and blow molded fittings, rotationally molded fittings and couplings, injection molded fittings and couplings, and rework materials. The resulting products shall be tested as appropriate, and shall conform to specified requirements for workmanship, dimension (inside diameter, length, minimum inner liner thickness, and perforations), stiffness, flattening resistance, impact resistance, and slow crack growth resistance of PE plastics without pigment.
