GB/T 7762-2014 《Rubber, vulcanized or thermoplastic―Resistance to ozone cracking―Static strain testing》 Related products

The GB/T 7762-2014 standard specifies the test method for ozone resistance of vulcanized rubber or thermal plasticity rubber under static tensile strain conditions and exposed to an environment containing a certain concentration of ozone. The test is conducted by placing the sample in a thermostatic closed test chamber, exposing it to a controlled ozone concentration, and evaluating whether it has occurred for a specified time. This standard is suitable for evaluating the checking tolerance performance of different rubber materials in an ozone environment, but it is not suitable for direct generalization to actual use conditions. During the test, attention should be paid to protecting the tester from ozone hazards and ensuring that the ozone concentration in the test chamber is controlled within the specified range to ensure the accuracy and safety of the test.
