ISO11341, ASTM D1248, ASTM D3451, ASTM D1148 Xenon Weathering Aging Test Chamber
Applications:
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.
