This specification covers requirements and test methods for materials, dimensions, workmanship, ring stiffness, flattening, joint systems, and a form of marking for polyethylene (PE) pipe of profile wall construction and with bell and spigot, heat fusion, extrusion welded or electrofusion joints for use in gravity flow applications, such as for sewers and drains. The PE profile wall pipe products cover six standard ring stiffness constant (RSC) classifications, namely 40, 63, 100, and 160, 250 and 400. These are referred to as RSC 40, RSC 63, RSC 100, RSC 160, RSC 250 and RSC 400. Referee testing, ring stiffness constant testing, flattening test, and joint tightness test shall be performed to meet the requirements prescribed.

1.1 This specification covers requirements and test methods for materials, dimensions, workmanship, ring stiffness, flattening, joint systems, and a form of marking for large diameter, 10 to 120 in. (250 to 3050 mm), inside diameter based polyethylene (PE) pipe of profile wall construction and with bell and spigot, heat fusion, extrusion welded or elctrofusion joints for use in gravity flow applications, such as for sewers and drains. Pipe produced to this specification should be installed in accordance with Practice D 2321 and with the manufacturer's recommendations.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are provided for information only.

The following safety hazards caveat pertains only to the test method portion, Section 8, of this specification: 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.
