(Specification)Standard Specification for Thermoplastic Elastomeric (TPE) Gasket Materials for Drain, Waste, and Vent (DWV), Sewer, Sanitary and Storm Plumbing Systems
Standard Specification for Thermoplastic Elastomeric (TPE) Gasket Materials for Drain, Waste, and Vent (DWV), Sewer, Sanitary and Storm Plumbing Systems
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 metric or inch/pound units shall be regarded separately as normative for this specification. The values in each system are not exact equivalents; therefore, each system shall be used independently without combining values.
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.
