This specification covers rigid plastic PVC and CPVC exterior compounds composed of poly (vinyl chloride), chlorinated poly (vinyl chloride), vinyl chloride copolymers or vinyl chloride blends, and the necessary compound ingredients intended for use in making building products. The compounding ingredients may consist of lubricants, stabilizers, nonpoly-(vinyl chloride) resin modifiers, colorants or pigments, or both, and inorganic fillers. It is intended to provide classification of base compounds used to manufacture PVC and CPVC exterior building products. The means for classifying and identifying rigid PVC building products compounds are provided as follows: kind of resin in compound, impact resistance, tensile strength, modulus of elasticity in tension, deflection temperature under a specific load and coefficient of linear expansion. PVC compound shall be in the form of cubes, pellets, granules, free-flowing powder blends, or compacted powder blends. Materials shall be of uniform composition and size and shall be free of foreign matter to a level that is not expected to affect processability, serviceability, or finished product appearance adversely.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers rigid plastic PVC and CPVC Exterior compounds composed of poly(vinyl chloride), chlorinated poly(vinyl chloride), vinyl chloride copolymers or vinyl chloride blends, and the necessary compound ingredients intended for use in making building products. The compounding ingredients are permitted to consist of lubricants, stabilizers, nonpoly(vinyl chloride) resin modifiers, colorants or pigments, or both, and inorganic fillers.
1.2 This specification is intended to provide classification of base compounds used to manufacture PVC and CPVC exterior building products. It is acceptable to determine physical properties by evaluating compounds of any color.
1.3 The requirements in this specification are intended for qualification, as well as for quality control of compounds used to manufacture building products. They are not applicable to finished building products.
1.4 It will be necessary, in special cases, to select specific compounds for unusual applications that require consideration of other properties not covered in this specification.
1.5 The rate of burning test, Test Method D635, is used in this specification only as a screening test for identification of certain properties of the PVC compound; there is no flammability test or flammability requirement for the compound.
1.6 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.7 The following safety hazards caveat pertains only to the test methods portion, Section 11, 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.
1.8 The text of this standard references notes and footnotes, which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.
1.9 It is possible that rigid PVC recycle plastic meeting the requirements of this specification will be usable in some applications. Refer to the specific requirements in the Materials and Manufacture Section of the applicable product standard.
