BS EN 13523-13-2001 "Coil cladding metals. Test methods, heat resistance accelerated aging performance", mainly specifies the method of accelerated weathering testing of coil cladding metals by heating. The standard specifies the preparation requirements of the sample, sets the key test conditions such as heating temperature and time, and specifies the evaluation method of the performance of the coating Appearance, adhesion, Color change after aging. It helps to quickly determine the durability of the coil cladding metal in the thermal environment, and provides a technical basis for the evaluation of product mass and application scenarios.
