This test method covers the standard material criteria and test method for compression gaskets used in joining hub and spigot cast iron soil pipe and fittings for sanitary drain, waste, vent, and storm piping applications. The gaskets shall be made of a compound containing a thermoset elastomer and shall consist of one or more sealing ring(s) that compress to provide an airtight and watertight seal. Compression gaskets shall have an integral flange to prevent the gasket from rolling into the hub during installation and shall be designed to permit expansion, contraction, and deflection of assembled piping. The gaskets shall be restrained and subjected to hydrostatic pressure and the joint assembly performance shall be evaluated using the restrained hydrostatic joint testing apparatus wherein a water pressure gauge is used to ensure the accuracy of the test pressures.1.1 Several different types of compression gaskets are available for use in connection with hub and spigot cast iron soil pipe and fittings. The purpose of this test method is to establish material criteria and test procedures for compression gaskets used in joining hub and spigot cast iron soil pipe and fittings for sanitary drain, waste, vent, and storm drain piping applications in accordance with the general needs of producers, distributors, and users.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.

This specification covers the properties of products made from dense thermoplastic elastomers used for compression seals, gaskets, setting blocks, spacers, and accessories for building construction sealing and glazing applications. The products are categorized into types according to resistance to tearing and compression set, grades based on durometer hardness, classes by flame propagation requirements, and into surfaces according to the surface characteristics. All products should be a performed extrusion manufactured from a thermoplastic vulcanizate and should conform to the specified requirements for tensile strength, elongation at break, hardness, ozone resistance, compression set, heat aging, tear resistance, brittleness temperature, and water absorption.1.1 This specification describes products composed of dense thermoplastic elastomers that are fabricated into gaskets and accessories (such as compression seals, setting blocks, spacers, and shims) for use in sealing and glazing applications in building construction. These products are used to seal or serve as components of compression sealing systems between mechanically restrained surfaces in building construction.1.2 The values stated in metric (SI) units are to be regarded as the standard. The inch-pound values given in parentheses are provided for information purposes only.1.3 Test Method C1166, as referenced in this specification, should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions.
