3、 Test method

Static tensile test
The standard stipulates that the two ends of the sample should be clamped on a fixture, and a tensile 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:
1. 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 the fixture, and the sample is cyclically stretched from 0 to the maximum 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. After the prescribed time, check the cracking condition of the sample, and generally select the ozone concentration
