The UV light climate resistance test is suitable for the aging test of the resistance to sunlight and artificial light sources. The test simulates the destructive effect of sunlight, moisture and temperature on materials; material aging includes fading, light loss, strength reduction, cracking, peeling, pulverization and oxidation. By simulating sunlight, condensation and natural humidity, the sample can reproduce the damage that may occur outdoors for several months or days in the simulated environment for several hours or even several years
