    Abstract

    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.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    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. However, results of this test may be used as elements of a fire risk assessment that takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.

    1.4 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 requirements prior to use.
