The ozone aging test chamber can be divided into "static ozone" and "dynamic ozone" according to its test methods and standards. Static means that the sample is stretched and put into the test chamber for testing, and the dynamic is to place the sample in the test chamber. On the fixture, the test is performed while stretching, and the stretching is about 5% to 45% of the sample itself. So what is the dynamic tensile test method for the ozone aging test chamber? Ba method The sample is alternately exposed by dynamic stretching and static stretching at a predetermined cycle, and the test sample is measured at the end of the specified exposure time, and the surface is recorded with or without cracks, or the degree of surface cracking, and Other performance changes may be detected as needed. 2.Bb method The maximum elongation of the dynamic tensile test of the sample shall be selected according to the actual use state of the vulcanized rubber. Generally, one or more of the following maximum elongation ranges are used for the test: 5±1%, 10±1% , 15 ± 2%, 20 ± 2%, 25 ± 2%, 30 ± 2%. The dynamic stretching and the static stretching are alternately exposed at a predetermined cycle. The exposure test is terminated by selecting the appropriate interval exposure time to detect the change of the sample until the surface of the sample is cracked, or when the sample reaches the new required crack level and performance change index.
