Historical (view previous versions of standard)
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.
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.
1.1 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 and health practices and determine the applicability of regulatory requirements prior to use.
