The technical execution standards are met by the UV weather resistance test chamber

The UV Weatherability Aging Test Chamber simulates the radiation damage of objects by ultraviolet light in sunlight and combines high temperature, humidity, condensation and dark environments to perform comprehensive photoaging tests on test objects. If the test items show discoloration, fading, brittle texture, cracking, powdering, peeling, etc., it means there is an obvious aging reaction under the ultraviolet light irradiation. The UV Weather Resistance Test Box uses fluorescent UV lamps to mimic the UV light in sunlight, combined with simulating the surrounding climate to conduct aging tests on test objects to study and understand the light stability of their materials.

There are certain technical standards for UV light weatherability testing. Currently there are clear technical specifications that include IOS, ASTMG, SAEJ, ISO, SATMDand other standards. The manufacture of the UV weathering test box is also made according to these standards, which illustrate the light intensity standard, the exposure standard of the test material and other weathering standards of the UV weathering resistance test.
