ISO11341 / ASTM D1148 Environmental Test Chamber For Xenon Weathering Aging Test

ISO11341, ASTM D1248, ASTM D3451, ASTM D1148 Xenon Weathering Aging Test Chamber





UV accelerated weathering test chamber simulates damaging effects of long term outdoor exposure of materials and coatings by exposing test samples to varying conditions of the most aggressive components of weathering - ultraviolet radiation, humidity and heat. A UV weathering test chamber uses fluorescent lamps to provide a radiation spectrum centered in the ultraviolet wavelengths. Moisture is provided by forced condensation, and temperature is controlled by heaters.
