适用范围：The scope of this document is to define a test method for performing the Compression Stress Relaxation (CSR) Test with the Automotive Standard (ASD) CSR Jig using the appropriate test fixtures, configurations and procedures. This standard defines the equipment needed, guidelines for running the test, and the format for generating the results and analyzing the data. This document describes test procedures and conditions for determining the loss in counter-force of a 12.7 mm (0.500 in) diameter button compressed in an ASD CSR Jig at a constant deformation, measured at room temperature at periodic intervals, after exposure to elevated temperatures and/or fluids. It is designed for testing of vulcanized rubber and thermoplastic elastomers with an instantaneous Type A Hardness from 45 to 90 (ASTM D2240). Samples are molded and cured in accordance with ASTM D3182. This document is specific to the use of the ASD CSR jig, a required apparatus list, a specific test method including a quality check for the total system. This document was developed based on testing new and aged specimens. This method can involve hazardous materials, operations and equipment. This method does not propose to address all the safety problems associated with its use. It is the responsibility of user of this method to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
