(Specification)Standard Specification for Flexible Cellular Materials-Vinyl Chloride Polymers and Copolymers (Closed-Cell Foam)
Standard Specification for Flexible Cellular Materials-Vinyl Chloride Polymers and Copolymers (Closed-Cell Foam)
ABSTRACT
This specification covers flexible closed-cell or non-interconnecting cellular products, the elastomer content of which is predominantly poly(vinyl chloride) foam or copolymers thereof. Materials shall be produced in sheet, strip, molded, or simple specific shapes. Complete details about apparatuses needed, specimen preparation, and procedures for the testing of compression deflection, compression set under constant deflection, and water absorption are thoroughly itemized.
SCOPE
1.1 This specification covers flexible closed-cell or noninterconnecting cellular products, the elastomer content of which is predominantly poly(vinyl chloride) or copolymers thereof.
1.2 In the case of conflict between the provisions of this specification and those of detailed specifications or methods of test for a particular product, the latter shall take precedence.
1.3 Reference to the methods for testing closed-cell poly(vinyl chloride) contained herein shall specifically state the particular test or tests desired and not refer to these methods of test as a whole.
1.4 The values stated in SI units are to be regarded as the standard. The inch-pound units given in brackets are for information only.
1.5 The following precautionary statement pertains to the test method portions only 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.
Note 1—There is no equivalent ISO standard.
