Xenon lamp aging tester and UV accelerated aging test box are the most widely used accelerated aging test equipment. Although these two test equipments are used to test the aging resistance of products, the test principle is completely different. Let us introduce The test principle of these two devices:
The xenon lamp aging test chamber is a spectrum that simulates all of the spectrum of sunlight, including ultraviolet (UV), visible, and infrared (IR). The xenon lamp spectrum is substantially consistent with the spectrum of sunlight in the range of 295 nm to 800 nm. Therefore, the xenon lamp aging test chamber was used to test a number of products that are sensitive to long wavelengths of ultraviolet light, visible light, and infrared light.
The UV aging test chamber cannot simulate full-spectrum sunlight. Its principle is that for the durable materials exposed to the outside, the short wavelength of ultraviolet light 300~400nm is the most important cause of aging damage. In the short-wave region of ultraviolet light, from 365 nm to the lowest wavelength of sunlight, the UV aging chamber can simulate sunlight well, however, it will be powerless for longer wavelengths.
The best method for testing a xenon lamp aging tester depends on the test needs, and each method can be very effective. The appropriate testing equipment should be selected based on the product or material being tested, the final application conditions, the degradation mode considered, and the budget.
