Ozone aging test chamber can be used for rubber products such as vulcanized rubber, thermoplastic rubber, cable insulation sheath and other products, under static tensile or continuous dynamic tensile deformation, or under intermittent dynamic tensile and static tensile alternating deformation, exposed to closed sunlight containing constant ozone concentration of air and constant temperature test chamber. The sample is tested according to the predetermined time, and the degree of cracking or other properties changes on the surface of the test sample is evaluated to evaluate the ozone aging resistance of the rubber.
