ASTM WK38695

    New Specification for Polyvinyl Chloride (PVC) Schedule 40 Plastic Drain, Waste, and Vent Pipe with a Cellular Core

    (What is a Work Item?)

    Developed by Subcommittee: F17.63 | Committee F17 | Contact Staff Manager


    1. Scope

    1.1 This specification covers coextruded poly(vinyl chloride) (PVC) plastic drain, waste, and vent pipe made to Schedule 40 iron pipe sizes (IPS) and produced by the coextrusion process with concentric inner and outer solid PVC layers and the core consisting of closed-cell cellular PVC. Plastic that does not meet the material requirements specified in Section 5 is excluded from single layer and all coextruded layers. 1.2 Fittings meeting the requirements of Specification D2665 are suitable for use with pipe meeting the requirements of this specification. 1.3 PVC plastic that does not meet the definitions of virgin PVC plastic as given in 5.1 is excluded, as performance of plastic other than those defined as virgin was not determined. PVC rework plastic that meets the requirements of rework plastic as given in 5.2 is acceptable. 1.4 Reprocessed plastic or recycled plastic as defined in Terminology D883 is excluded. 1.5 Recommendations for storage, joining, and installation are provided in Appendices X1, X2, and X3, respectively. 1.6 The text of this specification references notes, footnotes, and appendices that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification. 1.7 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.8 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.

    Currently, there is an ASTM standard that covers this type of pipe-co-extruded PVC with a cellular core (ASTM F891); however, this standard is not specific to DWV pipe. This product has been excluded from the Canadian National Building Code because the current standard is considered too general. A standard specific to DWV will allow consideration of PVC DWV pipe with a cellular core for inclusion into the NBC. At this time, ASTM F628 (ABS DWV Cellular Core Pipe) is included in the NBC.
