GB/T 13642-1992 "Ozone aging resistance test of vulcanized rubber, dynamic tensile test method" standard stipulates the method of evaluating the ozone aging performance of vulcanized rubber. The standard simulates the aging process of rubber in an ozone environment through dynamic tensile test, aiming to detect its ozone resistance performance. During the test, the sample is stretched at the specified ozone concentration and temperature, and its performance changes are recorded. This method can effectively evaluate the resistance of vulcanized rubber to ozone in the actual use environment, help manufacturers and users to choose suitable rubber materials, and improve the durability and Reliability of products.
