Standard Specification for Polyolefin Pipe and Fittings for Corrosive Waste Drainage Systems
This specification covers the requirements for non-pressure polyolefin pipe and fittings for corrosive waste drainage systems. The pipe is produced in Schedule 40 and 80 IPS sizes in two polyolefins (polyethylene and polypropylene) that shall contain suitable stabilizers and antioxidants and may contain pigments and fillers not detrimental to the pipe and fittings. The specimens shall conform to the outside diameter; wall thickness; average waterway diameter; chemical resistance to acetic acid, acetone, methyl alcohol, ammonium hydroxide, nitric acid, and sodium hydroxide; water absorption; system integrity; flattening; and impact resistance requirements. Hydrostatic pressure tests shall be conducted on both the heat-fused and mechanical joints.
1.1 This specification covers requirements for non-pressure polyolefin pipe and fittings for corrosive waste drainage systems.
1.2 Pipe is produced in Schedule 40 and 80 IPS sizes, and in DR IPS sizes for two polyolefins, polyethylene (PE) and polypropylene (PP).
1.3 The interchangeability of pipe and fittings made by different manufacturers is not addressed in this specification. Transition fittings for joining pipe and fittings of different manufacturers is provided for in this specification.
1.4 Pipe and fittings are joined by the heat fusion method ( Practice D2657 for PP butt and saddle fusion, Practice F2620 for PE butt, saddle and socket fusion and Practice F1290 for polyolefin electrofusion) or by using mechanical joints recommended by the manufacturer.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.6 The following safety hazards caveat pertains only to the test method, 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.
