1.1 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 2 to 60 in. [50 to 1500 mm].

1.2 The requirements of this specification are intended to provide non-pressure (gravity flow) pipe and fittings suitable for underground use for subsurface and land drainage systems, which do not operate under surcharge pressure heads.

Pipe and fittings produced in accordance with this specification are be installed in compliance with Practice D 2321 or Practice F 449 based on diameter limitations within the respective standards.

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.

1.3 This specification covers pipe and fittings with an interior liner using an annular exterior corrugated profile ().

1.4 Units The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system may not be exact equivalents: therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
