Scope of application: mainly applicable to non-metallic materials and rubber products such as: vulcanized rubber, thermoplastic rubber, wire and cable insulation sheath and other aging cracking test, under static tension or continuous dynamic tensile deformation, or intermittent Dynamic deformation and static tension alternate deformation, the product is exposed to air in a sealed, non-irradiated atmosphere with a constant ozone concentration, and a constant temperature test chamber is used to test the specimen for a predetermined period of time. Cracks or other properties that occur from the surface of the specimen are observed. The degree of change to assess the resistance to ozone aging properties of rubber.
