ASTM D4396-22

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

ABSTRACT
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. Materials shall be classified according to cell limits: Cell Class 0; Cell Class 1; Cell Class 2; Cell Class 3; Cell Class 4; Cell Class 5; Cell Class 6; Cell Class 7; and Cell Class 8. Conditioning; test conditions; tensile strength and modulus of elasticity; deflection temperature; and impact resistance tests shall be performed to meet the requirements specified.
SCOPE
1.1 This specification covers the classification and identification of 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. Compounding ingredients 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. Specific properties are not directly applicable to finished products. When specified in a product or application standard, the series of classification properties in this standard form a basis for a material specification. 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: 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: There is no known ISO equivalent to this standard.  
1.10 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
