Standard Test Method for Dimensional Changes of Elastomer and Rubber Materials Due to Exposure to Gaseous Hydrocarbon Environments
5.1 The information provided by this test method is useful for manufacturing quality control, technical service, and research purposes; and is required by various material specifications.
5.2 This method is suitable for all elastomer or rubber materials.
1.1 This standard gives the testing procedure to determine the change in dimensions of specimens of rubber or elastomeric materials, or both, resulting from exposure to gaseous hydrocarbon environments. The size of the specimens is such to facilitate preparation from as molded component configurations such as gaskets and seals. Where agreed to by both parties molded specimens may be used. Dimensional measurements are made prior to and after conditioning in a formulated test gas.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.3 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 limitations prior to use.
