GB/T 9640-2008 "Method for accelerated weathering test of soft and hard foam coalescence materials" specifies the method for accelerated weathering test of soft and hard foam coalescence materials under laboratory conditions. The standard evaluates the physical and mechanical properties of materials before and after aging by simulating natural aging conditions such as oxidation and hydrolysis, and is applicable to many types of foam materials. This standard provides a technical basis for performance evaluation and quality control of foam coalescence materials to ensure the Stability of materials during use.
