UVA Aging Machine

Name: UVA Aging Machine
Brand: Xi'an LIB Environmental Simulation Industry

The UVA aging machine installs UV lamps to simulate UVA ultraviolet radiation in natural sunlight, with a wavelength of 315-400nm, high intensity and stable UV radiation. Spray system and refrigeration system to create condensation, high temperature, high humidity and other environmental conditions, and perform accelerated weather resistance test on materials.

The temperature range can be from ambient to 90℃, humidity ≥95%RH, blackboard temperature（BPT） is 35℃ ~ 80℃, in order to simulate different climatic conditions, accelerate product aging.

Model: UV-SI-260,UV-260

Standard: ASTM G154, ASTM D 4329 – 05, ASTM C1257, ASTM C1442, ASTM C1519, ASTM C793, ASTM D1148, ASTM D3424, ASTM D3451, ASTM D4101, ASTM D4811, ASTM D6577, ASTM D6662

UVA Aging Machine Test Chamber Features and Benefits

1. The UVA aging machine can focus on the simulation of the long wave ultraviolet (UVA) band (315-400nm), which accounts for a relatively large proportion of sunlight's ultraviolet rays and has strong penetration.

2. Through the combination of enhanced UVA irradiation intensity and extreme environmental conditions (high temperature, rain), the aging process of the material in the natural environment for months or even years can be simulated in a relatively short time.

3. Equipped with water circulation system, automatic water intake and automatic filtration to ensure the smooth work of the spray system, save water resources.

4. Flexible and versatile sample holder customization to meet standard flat plate and complex 3D samples.
