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.
