Significance and Use

8.1 This specification describes types (based on resistance to tearing and compression set), grades (based on durometer hardness), class (based on flame propagation requirements), and surfaces (based on surface characteristics) of products as listed in Section 4 for various applications. It is essential, therefore, that the applicable type, grade, class, and surface be specified, as well as other options stated, so that the proper product is provided for the intended use.

Abstract

This standard specification describes products composed of dense elastomeric silicone rubber gaskets and accessories for use in sealing and glazing applications in building constructions. The products are classified according to type, hardness, class, and surface. Types include tear resistant and compression set resistant products. Surface of the product shall be smooth, clean, free from foreign matter, and shall not allow adhesion of sealants. Silicone rubber shall be manufactured from virgin polymer and shall be free from visible internal porosity, surface defects, and dimensional irregularities. The compound color shall be black unless specified otherwise. Test methods for the product shall include low temperature flexibility, hardness, compression, tensile strength, ultimate elongation, heat aging, ozone resistance, tear strength, flame propagation, specific gravity, staining, and color tests.

Scope

1.1 This specification describes products composed of dense elastomeric silicone rubber that are fabricated into gaskets and accessories (such as 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 and also as components in structural silicone sealant glazing systems.

1.2 The following precautionary statement pertains only to the test method portion, Section 10, of this specification. 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.

1.3 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 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

1.5 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.

1.6 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.
