The ISO 188 standard specifies accelerated aging and heat resistance test methods for vulcanized rubber or thermal plasticity rubber. The standard provides two test methods: Method A: Using the air oven method, using the unit oven or cabinet oven, the wind speed is low, and the air is changed 3 to 10 times per hour. Method B: Using forced air circulation oven method, using cabinet oven, forced air circulation through fan, 3 to 10 times per hour. These methods are used to evaluate the aging and heat resistance of rubber materials in high temperature environments. Through these tests, the durability and Reliability of rubber under actual use conditions can be predicted.
