Uv aging test chamber uses a fluorescent uv lamp as a light source to accelerate the weatherability test of the material by simulating uv radiation and condensation in natural sunlight to obtain the result of weatherability of the material. Applications 1. Simulate the sun, rain spray and condensation resulting damage to test the materials by exposure to sunlight with moisture and temperature. 2. To get the results of damage after several days or weeks which is equal to expose to outside for a few months. The damages include fading, discoloration, brightness down, powder, crack, blur, brittle, strength decreases and oxidation. 3. Provide reference with testing data for improvement of existing materials, or to assess the impact of changes in product durability and other aspects.
