GB/T 7762-2014
ActiveRubber, vulcanized or thermoplastic―Resistance to ozone cracking―Static strain testing
硫化橡胶或热塑性橡胶 耐臭氧龟裂 静态拉伸试验
Application Summary AI generated
This standard specifies a static strain testing method to evaluate the resistance of vulcanized or thermoplastic rubber to ozone cracking under controlled ozone concentration and temperature. It is applied in the rubber industry for quality control and material selection of products like seals, hoses, and gaskets exposed to ozone-rich environments, such as automotive components and outdoor industrial parts. The test helps predict long-term durability by simulating accelerated aging under static tensile stress.
