LBT-QUV UV Accelerated Weathering Test Chamber

This test apparatus simulates degradation caused by solar ultraviolet radiation by exposing the material under test to controlled high‑temperature illumination, thereby conducting weathering tests. It uses UV lamps to replicate the effects of sunlight and employs condensation and water spraying to mimic dew and rain. In just a few days or weeks, the UV exposure system can reproduce damage that would typically take months or even years to occur outdoors—such as fading, color change, loss of gloss, chalking, cracking, crazing, wrinkling, blistering, embrittlement, reduced strength, and oxidation. The test results can be used to select new materials, improve existing ones, or evaluate changes in material formulations.
