Bench UV Light Accelerated Aging Test Chamber – SAUV856 SAUV856 adopts UV fluorescence lamps to simulate sunlight effect. Its inner temperature and humidity can be properly controlled to obtain a continuing condensation on the sample for fully evaluating the damage caused by sunlight, humidity and temperature (effects caused by aging of the material may be fading, intensity reduction, cracking, flaking, chalking and oxidation). The UV light accelerated aging test chamber simulates in days or weeks the damage which, in real conditions, would occur in months or years. UV light can emulate the effect of sunshine, while condensation and water spray system can emulate the effects of rain and dew. It is possible to choose UVA or UVB lamps. UVA lamps provide a true simulation of sunlight in the short-wave range and are the most used to test the effects of sun damage. While UVB lamps, having an even shorter wavelength, simulate a much more severe and less realistic environment and are suitable for testing very durable materials, usually exposed to intense sunlight and for a long period of time. A typical test cycle generally carries out under strong irradiation of UV light or in a dark and wet condensation period with 100% relative humidity. These tests are generally employed in some specific fields, such as paint and coatings, automotive industry, plastic, wood, etc.
