Ozone aging test equipment supplied by manufacturers of ozone aging test chambers can be used for rubber products such as vulcanized rubber, thermoplastic rubber, cable insulation sheaths, etc. Under static or continuous dynamic tensile deformation, or alternating dynamic and static tensile deformation, exposed to sealed and unlit air containing constant ozone concentration and constant temperature test chambers, the samples are tested for a predetermined time. The degree of cracking or other performance changes on the surface of the samples is studied to investigate the effect of ozone on rubber

Static tensile test
The standard stipulates that the two ends of the sample should be clamped on a dedicated fixture, and a stretching elongation of 20% should be selected. The fixture should be installed on a rotating sample holder, with a rotation speed between (20-25) mm/S. The test should be conducted at a temperature of (40 ± 2) ℃, a relative humidity of no more than 65%, and a specified ozone concentration. Check the cracking condition of the sample after the specified time. The general selection of ozone concentration is (50 ± 5) × 10-8.
Dynamic tensile test
The standard stipulates that the sample fixture can automatically stretch and reset the sample, with a stretching frequency of 0.5 ± 0.025Hz. The two ends of the sample are clamped on a dedicated fixture, and the sample is cyclically stretched from 0% elongation to * * elongation. The fixture is installed on a rotating sample holder, with a rotation speed of (20-25) mm/S. At a temperature of (40 ± 2) ℃, a relative humidity of not more than 65%, and a specified ozone concentration, the fixture is cyclically stretched and reset and rotated with the sample holder for testing. Check the cracking condition of the sample after the specified time. The general selection of ozone concentration is (50 ± 5) × 10-8.
Dynamic tensile testing is divided into continuous dynamic tensile testing and intermittent dynamic tensile testing.
