Ultraviolet aging test
Ultraviolet aging test is mainly applicable to the aging test of non-metallic materials that are resistant to sunlight and artificial light. Ultraviolet aging test uses fluorescent ultraviolet lamp as light source. By simulating ultraviolet radiation and condensation in natural sunlight, accelerated weatherability test is carried out to obtain the results of weatherability of materials. It can simulate UV, rain, high temperature, high humidity, condensation, darkness and other environmental conditions in the natural climate. By reproducing these conditions, it can be combined into a cycle, and let it automatically execute the number of cycles.

Xenon Lamp Aging Test
Xenon lamp aging test is a test that simulates full sunlight spectrum. Xenon lamp aging test is a test that simulates artificial climate reliability test well at present. Artificial climate tests that are similar to natural ones can be simulated in a short time. This test can be used in the selection of new materials, improvement of existing materials, or to evaluate the durability of the material composition of the change test. It can provide corresponding simulation testing environment and accelerate testing for scientific research, product development and quality control. It can better simulate the changes of products exposed to sunlight in different environments.
Xenon lamp aging test in the ultraviolet region and visible region spectral energy distribution is similar to the solar spectrum energy distribution, the radiation emitted by the xenon lamp through the filter, filter out the wavelength of less than 290nm ultraviolet light wave and wavelength of more than 1200nm infrared light wave, so that the spectrum reached the sample surface is close to the solar spectrum. Coatings, plastics and other organic materials exposed to natural climate conditions and light radiation after a period of time will appear the loss of light, fading, yellowing, peeling, cracking, loss of tensile strength and the whole layer off and other phenomena. Even indoor light or sunlight through window glass can cause damage to substances such as pigments or dyes. As a result for outdoor use of paint, such as building coatings and automotive coatings, weatherability and light resistance is more important detection items.
Xenon lamp aging test products are suitable for plastics, food cosmetics, textiles, auto parts, packaging materials, building materials, rubber, paint, coatings, ink, paper, electronic and electrical products, etc.
