UV light in sunlight and diffuse sky radiation can cause alterations in the surface of materials which, accelerated by other climate factors such as temperature and humidity, lead to the typical symptoms of ageing. Staggered simulations of natural weathering in devices always requires a restriction of the number of climate values or their cyclic alterations. The Weiss Technik UV Test Chamber is an environmental simulation chamber that carries out UV light accelerated weathering tests on products and their materials.
