UV aging test standard

Product Details

Today, let's take a look at the standards for UV aging testing? The first principle of the experiment is to simulate the damage caused by solar ultraviolet light, by exposing the tested material to controlled high temperature light to conduct urban weather resistance testing on the material. It uses ultraviolet lamps to simulate the radiation effect of sunlight, and simulates dew and rain through condensation and water spraying. In just a few days or weeks, the ultraviolet irradiation equipment can withstand the damage that takes months or even years to occur outdoors, including fading, color changes, loss of luster, powdering, cracking, wrinkling, foaming, brittleness, strength reduction, oxidation, etc. Its test results can be used to select new materials, improve existing materials, or evaluate changes in material formulations.
