ASTM International Standard Specification for Rigid Poly(Vinyl Chloride) (PVC) and Related PVC and Chlorinated Poly(Vinyl Chloride) (CPVC) Building Products Compounds ASTM D4216-13

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.
