The GB/T 18949-2003 standard focuses on the evaluation of the ozone resistance performance of rubber and plastic hoses under dynamic conditions. The standard clarifies the relevant methods and requirements of the evaluation. Through the standardized process, the ability of such hoses to resist ozone erosion during dynamic operation can be accurately judged. It helps manufacturers to control the mass of products. It provides a basis for the evaluation of ozone resistance performance of products in different environments in the industry to ensure that the relevant hose products meet the mass and use standards.
