Deepak DWT accelerated weathering tester is a laboratory simulator of the damaging effects of weather. It is used to predict the relative durability of materials exposed to the outdoor environment. Rain and dew are simulated by a revolutionary condensation system. The damaging effects of sunlight are simulated by fluorescent UV lamps. Exposure temperature is automatically controlled, as the daily sequence of UV periods and condensation periods. Testing duration of deterioration effect can be reduce by DWT which may occur in a longer period like a month or years of outdoor exposure. Deterioration observed includes fading, chalking, cracking, crazing, hazing, blistering, gloss lose, strength lose, and embitterment.
