• Phạm vi áp dụng / Scope of standard: 1.1 This test method covers a procedure to determine the relative deterioration resistance of vulcanized rubber in a high temperature and high pressure oxygen environment. There may be no exact correlation between this accelerated test and natural aging of rubber because of the varied conditions of natural aging. This accelerated test is suitable for laboratory compound or product comparisons.Note 1 - For evaluating rubber vulcanizates under less severe conditions more nearly approaching natural aging, the use of Test Methods D 573 and D 865 is recommended.1.2 The values stated in SI units are to be regarded as the 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. (For specific precautionary statement, see Note 2.)
