UV Test Chamber

UV test chamber simulates damaging effects of long term outdoor exposure of materials and coatings by exposing test samples to varying conditions of the most aggressive components of weathering – ultraviolet radiation, moisture and heat. For the ultraviolet lamps test, Test engineers often choose three types of lamps: UVA-340 lamps, UVB-313 lamps and UVC 254 lamps.

The UV test chamber designed and manufactured by Wewon Environmental Chambers Co., Ltd. is a state-of-the-art piece of equipment that is designed to simulate the effects of sunlight and other UV sources on various materials. This technology is crucial for a wide range of industries, including the automotive, aerospace, and construction sectors, as it allows manufacturers to test the durability and longevity of their products under harsh UV exposure.

The Wewon UV test chamber meet GB/T14522-93 the method that mechanical products be accelerated tested in a artificial way with plastic, paint, rubber meterial, GB/T2424.14-1995 basic environmental testing procedures of electrical and electronic products, American material test institute ASTMG53-84 test method that non-metallic material exposed to fluorescent UV condensation. Based on your testing sample’s size, We has two options uv test chambers for choice.

What is the general irradiance range for the UV test ? The UV test chamber has eight ultraviolet lamps with spray system and humidification system. The machine able to simulate the environment of light, spray, condensation, etc., to carry out aging test on test samples. There has UVA 340, UVB 313 and UVA 351 tubes which can be used for UV testing.

Generally, UVA340 lamps are popular used for a long time on the market, with a wavelength range of 290~340nm. The irradiance of the UV test chamber is generally 40W ~ 50W/M2. Wewon Tech’s UV test chamber has a dimmable system, It can realization of UV aging test with real. Ultraviolet irradiance is adjustable from 15W to 45W/M2 at 290nm ~ 400 nm, 0.35W~1W@340nm, 0.3W~0.9W@313nm. Choose Wewon Tech’s UV chamber, You can realize the aging performance test for different test samples.

Question 1. Explain what is the relationship between UVA and nm ?
Answer: The wavelength range: 315~400nm, we named it’s UVA light.
Question 2. UVB lamps degrade material quicker than UVA lamps … correct ? Why ?
Answer: The wavelength range: 280~315nm, we named it’s UVB light. Because it’s short wavelength, It maks the testing material with a faster degradation.
Question 3. What is Irradiance ?
Answer: Irradiance is the unit, the lighting/ lamp’s strength. Unit: W/m2
Question 4. Is the test data downloaded to a spreadsheet or other format ?
Answer: Yes, You can use a USB and take it into the USB port of UV test chamber. The test data will transfer to USB automaticlly, You can check the data by computer by Excel formt.
Question 5. Single or Three phase power ?
Answer: We have single phase 230V, 50Hz, and three phase 380V, 50Hz for your options.
Question 6. Does Wewontech also provide color identification test units? For instance I would place my material into the UV test unit and I’d like to measure the change in color (if any) from before test and after test.
Answer: We don’t have the color identification equipment. If you found a good supplier from China, We can buy it for you and shipping to you together with our UV test chamber.
Question 7. How long does it take to simulate a 12 month test? And do you simply double this time frame for a 24 month test? Triple for a 36 month test, etc ?
Answer: It depends on different testing environmental. For examples, In Guangdong, China, The outdoors temperature range: +15– +20C, Testing 1 day in UV test chamber equal to simulate 28-30 days for outdoors test.
Question 8. Can you pause a 36 month test at the 12 and 24 month point to inspect and record information ?
Answer: Normally, The deterioration degree is nonlinearity, It can not doing a simple adding way !
