China [CN] UV weather aging test equipment
To simulate the harm caused by sunlight, the testing machine used fluorescent ultraviolet lamps to simulate the effect of sunlight exposure. The tested material is placed in the light at a certain temperature for testing. Hazards that occur outdoor for months or years can be recreated in days or weeks. Types of hazards include: color fading, discoloration, loss of light, power light, cracking, peeling, turbidity, bubbles, brittle, reduced strength, decay and oxidation. It’s widely used in coating ink pain, resin, plastic, printing packaging, adhesives, automotive and motorcycle industry, cosmetics, metals, electronics, electroplating and pharmaceutical industries.
HT-UV3(Light resource from the America brand ATLAS) UV1: Lighting; UV2:Lighting+condensation; UV3: Lighting+condensation+raining function. | ||

Lamp type | UVA-340 | UVA-313 |
Lamp life test | About 1800~2500H (Depend customer actual usage time, maybe 12 units one year) | |
Lamp difference | Use to compare with different polymers, because uv lamp no uv element below 295nm, dislike the UVB lamp can degenerate rapidly materials, The test will be closed to the outdoor results. UVA-340 Wavelength between 365nm and 295nm, peak wavelength in 340nm, use to compare the formulas of different samples. UVB lamp It gives of the unnatural light, wavelength below in 295nm, as test results, it is fatter than uv lamp, widely use in QC and testing durable materials. The test results were somewhat different those outside. There are two UVB lamp to use with same wavelength, the total uv content is different. | |
Lamp performance | ①0.68W/M²in 340nm equal to midday sunshine. | ①0.67W/M² in 310nm is standard. |
②1.38W/M²in 340nm equal to max. Double sunshine. | ②1.23W/M² in 310nm is rapid sunshine. | |
③0.35W/M²in 340nm is optimum average. | ③0.48W/M² in 310nm can extend the life of lamp. | |
④Equal to the March/September light, or low uv light | ④UVB-313 lamp testing meets SAE J2020 standard. | |
