The GB/T 24134-2009 standard is used to evaluate the ozone resistance performance of rubber and plastic hoses under static conditions. It specifies the requirements of test equipment, such as ozone aging test chambers, specifies the test steps, including preparing the hose sample, adjusting the ozone concentration and temperature of the test environment, placing the sample in it and regularly checking the Appearance changes. Ozone resistance performance affects the service life of the hose outdoors or in an ozone environment. According to this standard, the manufacturer can accurately test the product to ensure that the hose can resist ozone erosion in actual use and maintain good performance. It is widely used in automotive, aviation, industrial transportation and other fields.
