(Specification)Standard Specification for Styrene-Rubber (SR) Plastic Drain Pipe and Fittings
Standard Specification for Styrene-Rubber (SR) Plastic Drain Pipe and Fittings
ABSTRACT
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.
SCOPE
1.1 This specification covers requirements and test methods for materials, dimensions, workmanship, impact resistance, load-deflection properties, dimensional stability, and joint tightness of plain-end or bell-end styrene-rubber (SR) plastic drain pipe and fittings in sizes 2 through 6 in.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 The following safety hazards caveat pertains only to the test methods 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.
