Standard Specification for Poly (Vinyl Chloride) (PVC) Gaskets for Drain, Waste, and Vent (DWV), Sewer, Sanitary, and Storm Plumbing Systems

ABSTRACT
This specification describes material and physical requirements for virgin nonrigid poly(vinyl chloride) (PVC) preformed molded and spliced gaskets used in mechanical couplings for gravity flow drain, waste, and vent (DWV), sewer, sanitary, and storm plumbing systems. They include couplings that join similar and dissimilar piping sizes and piping materials. Recycled materials may also be used in this product. Properly sampled specimens shall undergo tests, and shall conform accordingly to the following property requirements: durometer hardness; tensile strength; volatile loss; brittleness temperature; hardness increase, loss in tensile strength, and loss in elongation after heat aging; water absorption and weight increase; cracks and ozone resistance; volume increase and decrease after oil immersion; stress relaxation; and force retention.
SCOPE
1.1 This specification describes material and physical requirements for nonrigid poly (vinyl chloride) (PVC) preformed molded and spliced gaskets used in mechanical couplings. These couplings are used in gravity flow drain, waste, and vent (DWV), sewer, sanitary, and storm plumbing systems. They include couplings to join similar and dissimilar piping sizes and piping material.
1.2 Recycled materials may be used in this product in accordance with the requirements in Section .
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are given for information only. Note 1There are no ISO standards covering the primary subject matter of this specification.
1.4 The following safety hazards caveat pertains only to the test method portion, Section 7, 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.
