ASTM D4216-22

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Standard Specification for
Rigid Poly(Vinyl Chloride) (PVC) and Related PVC and
Chlorinated Poly(Vinyl Chloride) (CPVC) Building Products
Compounds
This standard is issued under the fixed designation D4216; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope*
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.
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.
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, health, and environmental practices and determine the applicability of regulatory
limitations prior to use.
This specification is under the jurisdiction of ASTM Committee D20 on Plastics and is the direct responsibility of Subcommittee D20.15 on Thermoplastic Materials
(Section D20.15.08).
Current edition approved Dec. 1, 2017May 1, 2022. Published January 2018May 2022. Originally approved in 1983. Last previous edition approved in 20132017 as
D4216 – 13.D4216 – 17. DOI: 10.1520/D4216-17.10.1520/D4216-22.

NOTE 2—There is no known ISO equivalent to this standard.
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.
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.

3. Terminology
3.1 Definitions:
3.1.1 General—Definitions are in accordance with For definitions of terms pertaining to plastics used in this standard, refer to
Terminology D883 and . For abbreviations used in this test method, refer to Terminology D1600, unless otherwise indicated.
3.2 Definitions of Terms Specific to This Standard:
3.2.1 temperate northern climate—climate, n—in weather testing, a North American metropolitan area testing site located within
73° to 100°W longitude and 37° to 45°N latitude.
4. Classification
4.1 The means for classifying and identifying rigid PVC building products compounds are provided in Table 1. The properties
enumerated in this table and the tests defined are expected to provide identification of the compounds selected. They are not
necessarily suitable for direct application in design because of differences in shape of part, size, loading, environmental conditions,
etc.
4.2 Classes are designated by the cell number for each property in the order in which they are listed in Table 1.
NOTE 3—Because of the large number of property requirements, the properties of classes are divided into groups for easy identification of the selected
materials. The groups are the following: kind of resin in compound, strength properties, and dimensional stability. The class numbers are grouped as
shown by the following example:

combination, for a broad range of materials. This type format, however, is subject to possible misapplication since unobtainable property combinations
can be selected if the user is not familiar with commercially available materials. The manufacturer should be consulted.
