Aging test is to simulate the product involved in the real conditions of use of various factors on the aging of the product produced the corresponding experimental conditions to strengthen the process, the experiment aimed at plastic materials, common aging aging are light, heat aging, hot air aging . Products affected by long-term use in outdoor sunlight, you want to understand the life of the product can be used outdoors should simulated solar ultraviolet UV aging test, of course, the real test of strength than the intensity of outdoor light to be much larger, thereby reducing test time can learn through the use of short-term test products many years of aging. Annual product loss due to aging caused up to billions of dollars, material aging, including fading, loss of light intensity decreases, cracking, peeling, chalking and oxidation. Specifically, the sunlight (especially UV), heat and humidity can cause aging of the material. These factors are usually combined effect, leading to failure could otherwise be a single light or an anti-anti-wet material. Common Test Equipment: UV resistant climate chamber carbon arc lamp aging chamber xenon arc lamp weathering test chamber temperature and humidity chamber metal halide salt spray test chamber ozone aging me alternating high and low temperature thermal condensation chamber aging air box
