Standard Specification for Styrene-Rubber (SR) Plastic Drain Pipe and Fittings (Withdrawn 2022)

This specification covers the material, dimensional, and mechanical requirements, and the corresponding test methods for plain-end or bell-end styrene-rubber (SR) plastic drain pipes and fittings in 2 to 6 in. sizes that are suitable for nonpressure underground drainage of sewage and certain other liquid wastes, in applications outside the building limits, where dimensional stability, resistance to aging, and strong eight joints are required. The SR plastics shall contain styrene plastics combined with rubber (polybutadiene or butadiene-styrene type, or both) and compounding materials such as antioxidants and lubricants, and may contain acrylonitrile. When evaluated using the test procedures prescribed herein, the finished pipes and fittings shall conform to the following requirements: workmanship; dimensions such as socket and pipe diameters, wall thickness, laying length, socket depth, and dimensional stability; and mechanical properties such as impact strength, stiffness and deflection temperature, tensile strength and elongation at rupture, modulus of elasticity in tension, Izod impact strength, flattening resistance, solvent cement, and joint tightness.
