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 inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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.
ASTM C1440-21 is the internationally recognized standard specification for thermoplastic elastomeric (TPE) gasket materials used in drain, waste, and vent (DWV), sewer, sanitary, and storm plumbing systems. Published by ASTM International, this standard establishes uniform requirements for TPE gasket materials employed in both shielded and non-shielded mechanical couplings, facilitating reliable connections between similar and dissimilar piping sizes and materials. The standard ensures that these gaskets deliver the necessary durability, chemical resistance, and mechanical performance required for gravity flow plumbing applications.
ASTM C1440-21 applies broadly to the infrastructure of municipal, commercial, and residential plumbing and wastewater systems. Principal uses include:
