In our daily life, common sense tells us that white or light-color substances are easy to turn yellow at exposure to ultraviolet irradiation for a long time. In order to predict this phenomenon, people have to figure out a device to determine it.
UV Light Yellowing Resistance tester is an environmental test chamber that provides a simulative environment exposed to the radiation of intensive UV(ultraviolet). The test piece is put under UV light. The degree of specimens’ change in color is observed within the defined time to judge the resistance to color fading.
