1. Scope

1.1 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; non-poly(vinyl chloride) resin modifiers; colorants or pigments, or both; fibrous or nonfibrous reinforcements; or fillers.

1.2 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.

1.3 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.

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

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

1.6 Rigid PVC compounds for general purpose extrusion and molding use are covered in Specification D 1784. Specification D 1784 is applicable to piping applications involving special chemical and acid resistance.

1.7 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.

1.8 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.9 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this specification.

1.10 Rigid PVC and CPVC recycle plastics meeting the requirements of this specification may be used in some applications. Refer to the specific requirements in the Material and Manufacture Section of the applicable product standard.

1.11 The following safety hazards caveat pertains only to the test methods portion, Section , 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.

Note 1There are no ISO standards covering the primary subject matter of this specification.
