 UV aging tester simulates light aging

UV aging tester is suitable for the aging test of non-metallic materials against sunlight and artificial light source. The source uses 8 UV fluorescent lamps with rated power of 40W as the light source. UV fluorescent tubes, distributed on both sides of the machine, 4 on each side (there are UVA-340 and UVB-313 light source for users to choose the configuration).d9ETextile Testing Instruments, Testing Equipment Manufacturer

UV aging test chamber is a simulation of light aging test equipment, specially simulated products placed in the outdoors for a long time. The destructive nature of its exposure to ultraviolet light from the sun takes only a few days or weeks, and the equipment can reproduce the damage caused by the outdoor need for months or years. See if the product has fading, discoloration, brightness loss, chalking, cracking, blurring, brittleness, strength loss and oxidation, etc. It can also reproduce the damage produced by rain and dew. The UV aging tester performs the test by exposing the sample to be tested in a controlled interactive cycle of sunlight and moisture while raising the temperature. (UV fluorescent lamps are used to simulate sunlight, while the effects of moisture can be simulated by condensation or spraying).d9ETextile Testing Instruments, Testing Equipment Manufacturer

Ultraviolet (UV) light accounts for only 5% of sunlight, but it is the main light factor that causes deterioration in the durability of outdoor products. There are several different UV lamps to choose from, and in most cases, only short-wave UV light is required to simulate it. Most of these UV lamps produce mainly UV light, rather than visible and infrared light. The main difference between the lamps is reflected in the difference in the total UV energy they produce in their respective wavelength ranges. Different lamps will produce different test results. The actual environment of the exposure application can suggest which type of UV lamp should be used.d9ETextile Testing Instruments, Testing Equipment Manufacturer

UVA-340, the choice for simulating the suns UV rays. UVA-340 can well simulate the critical short-wave wavelength range of the sunlight spectrum, i.e., the wavelength range of 295-360 nm, UVA-340 only produces the spectrum of UV wavelengths that can be found in sunlight.d9ETextile Testing Instruments, Testing Equipment Manufacturer

UVB-313 for large degree of accelerated testing. UVB-313 can provide test results very quickly.d9ETextile Testing Instruments, Testing Equipment Manufacturer

UV aging tester standard definition of emission of light energy below 300nm is less than 2% of the total output light energy of a fluorescent UV lamp, usually called UV-A lamp; emission of light energy below 300nm is greater than 10% of the total output light energy of a fluorescent UV lamp, usually called UV-B lamp.
