Meaning and use
4.1 Rubber and rubber products need to resist the deterioration of physical properties over time caused by oxidation and thermal aging. The test method provides a way to evaluate these performance characteristics of rubber under certain acceleration conditions specified.
4.2 For important information on standard compounds used for precision testing to accelerate test aging assessment, see Annex A1.
ASTM D573-2019 “Rubber Hot Air Aging Test Method Standard”
Radius
1.1 This test method covers procedures for determining the effect of high temperature on the physical properties of vulcanized rubber. Because performance conditions vary widely, the results of this test method may not fully correlate with service performance. However, the test method can be used to evaluate rubber compounds on the basis of laboratory comparisons.
1.2 Values expressed in SI units shall be considered standard. The values given in parentheses are for reference only.
1.3 This standard is not intended to address all safety concerns, if any, associated with its use. It is the responsibility of users of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use. See Note 1 for specific precautions.
1.4 This international standard is based on internationally recognized standardization principles established in the Decision on Principles for the Development of International Standards, Guidelines and Recommendations issued by the WTO Committee on Technical Barriers to Trade.
