T/CSAE 134-2020 Car resistance to aging, solar tracking concentrator outdoor accelerated aging test method
Basic Information
Scope
Main technical content: This standard specifies the terms and definitions, test site requirements, equipment, safety precautions, samples, test procedures, and results for accelerated aging tests of automotive exterior materials using a Fresnel reflection system with the sun as the light source. This standard applies to accelerated aging tests of automotive exterior materials using a Fresnel reflection system with the sun as the light source. The equipment and methods specified in this standard can be used to determine the relative aging resistance of automotive materials exposed to sunlight, heat, and humidity, provided that the physical and chemical mechanisms that play a decisive role in accelerating the aging rate of the materials during the test have not changed. The test results of this standard can be used to compare the relative aging resistance of automotive exterior materials after a specific cycle of testing. Any accelerated exposure test cannot be considered a complete simulation of natural or on-site exposure. Only when the comparable performance levels of the tested materials have been determined can the test results of this standard be considered representative of the results of natural or on-site exposure tests.
