Standard Specification for Rigid Poly(Vinyl Chloride) (PVC) and Chlorinated Poly(Vinyl Chloride) (CPVC) Compounds for Plastic Pipe and Fittings Used in Nonpressure Applications
 N D4396

Annotation

This specification covers rigid plastic compounds intended for use in making nonpressure piping products composed of (1)poly(vinyl chloride) polymer, (2) chlorinated poly(vinyl chloride) polymer, or (3) vinyl chloride copolymers, and the necessary compound ingredients. The compounding ingredients may consist of lubricants; stabilizers; nonpoly( vinyl chloride) resin modifiers; colorants or pigments, or both; fibrous or nonfibrous reinforcements; or fillers.

The requirements in this specification are intended for the quality control of compounds used to manufacture pipe or fittings intended for nonpressure use. They are not applicable to finished pipe and finished fittings. See the applicable ASTM standards or requirements for finished products.

It may be necessary, in special cases, to select specific compounds for unusual piping applications that require consideration of other properties not covered in this specification, such as service temperature, sag resistance, special chemical resistance, weather resistance, bending forces, and electrical properties.

Rigid PVC compounds for pressure applications are covered in Specification D 3915.

Rigid PVC-type compounds for building applications other than piping are covered in Specification D 4216.

Rigid PVC compounds for general purpose extrusion and molding use are covered in Specification D 1784.

The rate of burning test, Test Method D 635, is used in this specification as a test for identification of certain properties of the compound.
