The JIS K6257-2017 standard specifies methods for the determination of heat aging performance of vulcanized rubber and thermal plasticity rubber. The performance changes of rubber in high temperature environments are evaluated through accelerated weathering tests and heat resistance tests. These tests are used to determine the heat resistance and aging Stability of materials to ensure Reliability in long-term use. The standard provides standardized test methods for the heat aging evaluation of rubber materials, which are widely used in the quality control and research and development of rubber products.
