ASTM D4396-15

1.1 This specification covers the classification and identification of rigid plastic compounds intended for use in making nonpressure piping products composed of 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 In special cases, 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, shall be considered.

1.4 Rigid PVC-type compounds for building applications other than piping are covered in Specification D4216.

1.5 Rigid PVC compounds for general purpose extrusion, molding, fitting, and pipe are covered in Specification D1784.

1.6 The rate of burning test, Test Method D635, is used in this specification as a test for identification of certain properties of the compound.

1.7 It is acceptable for rigid PVC and CPVC recycle plastics meeting the requirements of this specification to be used in some applications. Refer to the specific requirements in the Material and Manufacture section of the applicable product standard.

1.8 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

1.9 The following safety hazards caveat pertains only to the test methods portion, Section 10, of this specification: Note 1: There is no known ISO equivalent to this standard.
