This specification covers high-temperature and acid-resistant fluorocarbon terpolymer elastomers used in the manufacture of expansion joints for coal-fired utilities and other high-temperature industrial applications in which corrosive flue gases are present. The materials should be black and based on virgin fluoroelastomer terpolymers with chemical compositions that meet the requirements. Samples should also satisfy the required values of hardness, tensile strength, elongation, weight, and specific gravity.1.1 This specification covers requirements for the fluorocarbon terpolymer elastomer used in the manufacture of expansion joints for use in coal-fired utilities and other high temperature industrial applications in which corrosive flue gases are present.1.2 This specification is intended as a reference procedure for evaluating the performance of these vulcanizates and can also be used for quality assurance testing before release of a lot based on agreement between supplier and purchaser.1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.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, health, and environmental practices and determine the applicability of regulatory requirements prior to use.1.5 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.
