The standard HG/T 2869-1997 "Rubber and plastic hoses, Evaluation of ozone resistance performance under static conditions" specifies the test method for the ozone resistance performance of rubber and plastic hoses under static conditions. This standard details three different determination methods for evaluating the tolerance of hose outer coatings in an ozone environment. This standard provides a scientific basis for the manufacture and quality control of rubber and plastic hoses, ensuring the anti-aging performance of products in practical applications. The implementation of the standard helps to improve the service life of hoses and reduce the problems of aging and breakage of hoses caused by ozone erosion.
