ASTM D1148 Compliant UV Anti-Yellowing Aging Test Chamber with UV300W Sunlight-Simulation Lamp and Forced Hot-Air Circulation Heating
منتوج وصف
Product Overview The UV Anti-Yellowing Aging Test Chamber — also known as a bulb-type UV discoloration tester or yellowing resistance tester — determines how well white and light-colored materials resist yellowing under simulated sunlight and heat. A 300 W UV bulb irradiates specimens placed on a slowly rotating φ300 mm turntable, while a forced hot-air circulation system holds the chamber at a set temperature up to 80 °C. After the programmed exposure period, the exposed
