Standard Specification for
Rigid Poly(Vinyl Chloride) (PVC) and Related PVC and
Chlorinated Poly(Vinyl Chloride) (CPVC) Building Products
This standard is issued under the fixed designation D 4216; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
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 may 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 a classification of
base compounds used to manufacture PVC and CPVC exterior
building products. Physical properties may be determined by
evaluating compounds of any color.
NOTE 1—Two year weathering studies, without specific requirements
for color change and physical property change, are recommended for all
colors of new compounds and compounds for new applications to provide
the basis for agreement between producer and buyer on the suitability of
the compound for the intended application.
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. See Specifications D 3679, D 4477,
D 4726, and F 964 for requirements for finished products.
1.4 It may 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 D 635, 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 the
standard. The values given in parentheses are for information
