The TSM 0501G standard is a standard used by Toyota to test the weather resistance of plastic molding materials. The standard defines the test method for the resistance of plastic parts to light aging in an outdoor environment, mainly by xenon arc aging test. The test involves using different models of xenon arc aging test chambers (such as the Q-SUN Xe series) and controlling the irradiance to evaluate the durability of plastic materials. The standard helps to ensure the performance Stability and long life of plastic materials in the actual use environment.
