This specification covers requirements and test methods for annular corrugated profile wall polyethylene pipe and fittings with an interior liner. The inside diameters covered are 50 mm to 1500 mm [2 in. to 60 in.]. The requirements of this specification are intended to provide non-pressure (gravity flow) pipe and fittings for underground use for subsurface and land drainage systems, which do not operate under surcharge pressure heads. NOTE 1: Pipe and fittings produced in accordance with this specification are be installed in compliance with Practice D2321 or Practice F449 based on diameter limitations within the respective standards. NOTE 2: Subsurface and land drainage systems pertain principally to non-municipal or private facilities for water table control, storm drainage and agricultural drainage applications. The products supplied under this specification are not intended for any sanitary sewer or municipal storm sewer applications. This specification covers pipe and fittings with an interior liner using an annular exterior corrugated profile (Fig. 1). This specification permits the use of recycled materials for pipe in accordance with the requirements in Section 5.
