1.1 The specification covers a two-part flowable space grade room temperature vulcanizing (RTV) silicone rubber adhesive or compound. The material is specifically designed for applications requiring extreme low temperature, low outgassing and minimal volatile condensibles under extreme operating conditions. The RTV silicone rubber should be suitable for withstanding environmental exposure to temperatures from –115 to 200°C (–175 to 392°F). The material should also withstand the combination of stress, temperature, and relative humidity expected to be encountered in service. The RTV silicone rubber may be used as a sealing, caulking, potting or bonding material for applications on metal, plastics, rubber, glass, and ceramic products. Types I and II are often used as coatings.
1.2 The values stated in SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.
1.3 The following precautionary statement refers to the test method portion only, Section 8, 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.
1.4 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.
