ABSTRACT
This specification covers preformed rubber gaskets used to seal joints in cast iron soil pipe and fittings. Gaskets shall be made of a properly vulcanized virgin rubber as the sole elastomer with no scrap or reclaim. Gaskets shall conform to the required physical properties such as hardness, elongation, tensile strength, tear strength and compression. The gasket material shall be tested for effects of heat aging. They shall be tested for weight increase due to water absorption and shall also be tested for volume decrease due to oil absorption. Gasket material shall be tested for ozone resistance.

ABSTRACT
This specification covers thermoplastic elastomeric (TPE) gasket materials for preformed elastomeric gaskets used in shielded and non-shielded mechanical couplings for gravity flow drain, waste, and vent (DWV), sewer, sanitary, and storm plumbing systems. Couplings include those that join similar and dissimilar piping sizes and materials. Gaskets shall be made of virgin thermoplastic elastomeric compound containing only clean reworked thermoplastic elastomer material. Gasket materials shall conform to specified values of the following physical requirements: hardness, elongation, tensile strength, heat aging, tear strength, water absorption, ozone resistance, compression set, oil immersion in IRM 903 oil, and stretch test for spliced gaskets.
SCOPE
1.1 This specification covers thermoplastic elastomeric (TPE) gasket materials for preformed elastomeric gaskets used in shielded and non-shielded 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 material.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 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.
