Ultraviolet light (UV) makes up only 5% of sunlight, but it is the main light factor that reduces the durability of outdoor products. Several different UV lamps are available and in most cases only simulated shortwave UV light is required. Most of these UV lamps produce ultraviolet light rather than visible and infrared light. Lamps differ primarily in the total UV energy they produce in their respective wavelength ranges. Different lamps lead to different test results. Actual exposure application environment can indicate what kind of UV lamp should be used. Sunlight and moisture damage to materials causes tens of thousands of economic damages every year. The UV light weatherability test chamber can reproduce the damage caused by sunlight and dew. Test The chamber exposes the material to be tested to a controlled cycle of sunlight and humidity simultaneously, the test is performed by increasing the temperature. The test box uses UV fluorescent lamps to simulate sunlight while simulating the effect of moisture through condensation.

The UV-UV aging test chamber is used to simulate the damage caused by ultraviolet light, rain and dew by subjecting the tested material to the interaction between light and moisture at a controlled high The material is tested during the variable cycle. It uses UV lamps to simulate the radiant effects of sunlight and uses condensation and water spray to simulate dew and rain. In just days or weeks, UV-irradiated devices can reproduce damage that would take months or years outdoors, including fading, discoloration, tarnishing, chalking, cracking, crackingse, wrinkling, blistering, embrittlement, strength degradation, oxidation, etc. Test results can be used to select new materials, improve existing materials, or evaluate changes in material formulations.
