1.  Function

The UV Accelerated weathering test chamber stimulates dew and rain with consideration for humidity and/or water sprayequipped with fluorescent UV lamps which can completely simulate the UV spectra of sunlight, exposes materialstoalternating cycles of UV light and moisture at controlled, elevated temperatures. It’s most widely used weatheringtesterto test types of damages include color change, gloss loss, chalking, cracking, crazing, hazing, blistering, strengthlossand oxidation. The source adopts 8 pieces of UV lamps of 40W as the light source. The lamps are distributed onthetwosides of machine, 4 pieces for each side (UVA-340 and UVB-313 optional), 8 pieces in total .
