​Uv Accelerated Weathering Aging Test Chamber can simulate the ultraviolet ray in the sun, rain and dew to damage the material, QUV using UV lamp simulate the effect ultraviolet ray of sunlight, cold rain and dew.

Accelerated weathering test methods simulate extreme weather conditions using special environmental chambers and instruments that accelerate the aging process. Environmental influences can cause discoloration, cracking, corrosion and deterioration of the product inside and out.

1. Simulated Sunlight
Damage to material durability is primarily caused by the sun's ultraviolet rays, which produce very little energy in the visible or infrared spectrum. We can choose UV lamps with different wavelengths according to different test requirements, because the total energy and wavelength of UV radiation in each lamp tube are different. Generally, UV lamps can be divided into two types: UVA and UVB.
2. UV Lamp Type

UVA-340 lamp tube: UVA-340 lamp tube can well simulate the short-wave ultraviolet rays in sunlight, that is, the sunlight whose cut-off wavelength is 365nm to 295nm.
UVB-313 lamps: UVB-313 lamps generally emit short-wave ultraviolet rays that are stronger than the sun's ultraviolet radiation on the earth's surface, which can accelerate material aging to the greatest extent.
UVA-351 lamp: simulates the ultraviolet sunlight through the window, which is the most effective for testing the aging of indoor materials.​
