This specification covers coextruded acrylonitrile-butadiene-styrene (ABS) plastic drain, waste, and vent pipes made to Schedule 40 iron pipe sizes (IPS) with concentric inner and outer solid ABS layers and a closed-cell cellular ABS core. The ABS plastics used to make the pipes shall only be either virgin or reworked as specfieid. Reprocessed or recycled plastics are excluded from this specification. The pipes shall meet specified requirements for dimension such as outside diameter, wall thickness, and length; and for performance such as pipe stiffness, lower confidence limit, flattening resistance, impact strength, bond strength, pigments or screening agents, and solvent cement.

1.1 This specification covers coextruded acrylonitrile-butadiene-styrene (ABS) 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 ABS layers and the core consisting of closed-cell cellular ABS. Plastic which does not meet the material requirements specified in Section 5 is excluded from single layer and all coextruded layers.

1.2 Fittings suitable for use with pipe meeting the requirements of this specification are given in Annex A1. Fittings meeting the requirement of Specification D 2661 are also acceptable.

1.3 Acrylonitrile-butadiene-styrene plastic which does not meet the definitions of virgin ABS plastic as given in 3.2.4 is excluded, as performance of plastic other than those defined as virgin was not determined. ABS rework plastic which meets the requirements of rework plastic as given in 5.3 is acceptable.

1.4 Reprocessed plastic or recycled plastic as defined in Terminology D 883 is excluded.

1.5 Recommendations for storage, joining, and installation are provided in Appendixes X1, X2, and X3, respectively.

1.6 The text of this specification references notes, footnotes, and appendixes which 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.
