Environmental Aging Resistant Test Chamber , Accelerated Weathering Instrument



SANWOOD UV Light Accelerated Aging Test Chamber (hereinafter referred as BUV)adopts fluorescent UV lamp as the light source. Its inner temperature and humidity can be properly controlled to obtain the periodic condensation on the sample for fully evaluating the damaged factor causedby sunlight, moisture and temperature (materials aging phenomenon includes fading, disluster, intensity reduction, cracking, flaking, chalking, and oxidation).
Fluorescent UV light can emulate the effect of sunshine, while condensation and water spray system can emulate the effects of rain and dew. During the test, radiation energy and temperature are controllable. A typical test cycle generally carries out under strong irradiation of UV light or in the dark and wet condensation period with 100% relative humidity. These tests generally applied in the fields of paint and coatings, automotive industry, plastic, wood, glue, etc…

◆ Original UVA or UVB lamps from America, ensure the comparability of testing results.

All BUV machines use fluorescent UV lamps produced by Amercian as testing light source, comparing with other type lamps (including Xenon Lamps), UV lamps are more stable. Its spectrum power distribution won’t change as the lamps weathering, even to 6,000 hours. Thus more repeatable testing results can be achieved easily, and decrease changing lamps times and reduce the running cost..

Furthermore, these lamps from Amercian are produced on the base of more than 40 years’ experience and fluorescent technology. It is designed specially and tested with most serious quality control.


◆ With Original Intellectual Property Rights and Initiated in China, our ballast can extend the lamp lift to 6,000 hours, save use-cost greatly for users.


◆ Irradiance can be calibrated automatically (Only for BGD 856)

As any other lamps, UV lamps energy of BUV also decreases as time increase. The control system would compensate it automatically through strengthening the voltage of lamps. But as the using time become longer and longer, the energy of lamps decrease continuously. For some high set point of irradiance, BUV couldn’t keep this irradiance any longer, and now the system of BUV would reminder failure “the error of irradiance is too large” and shut off the machine. Now, the operator should calibrate the BUV by standard calibration radiometer. If machine still can’t get the set point after calibrating, the user should replace the two pcs lamps corresponding to the relative sensor and calibrate again.

BUV is calibrated by BGD Calibration Radiometer which is produced by our company. User can use one radiometer to calibrate some BUV, radiometer can test fluorescent UV lamps. It is not only used to calibrate the UVA lamps , but also to do UVB lamps. For UVB lamps, it has been calibrated well under the wave length 313 nm with W/m2/nm unit before delivery. For UVA lamps, it has been calibrated well under the wave length 340 nm with W/m2/nm unit.

Calibration Radiometer is made up of radiometer and sensor(see picture as below):

The sensor of BGD 8118 calibration radiometer is very sensitive to ultraviolet rays, but don’t have any action to visible light, and just have a little response for infrared light even can be ignored. So other rays can’t bring any influence for this radiometer.

◆ Water Spray and Condensation function

Water spray

For some applications, the water spray can simulate end-use environmental conditions better. Water spray can effectively simulate heat shock or mechanical erosion caused by dramatic temperature changes or rain. In some practical application conditions, such as a sudden brash in a sunshine day, can bring heat shock because the temperature of the material changes drastically. This heat shock severely tests the properties of many materials. BUV water spray can simulate this heat shock and / or stress corrosion.

BUV spray system design with 12 nozzles, each side has 6 pieces in the test chamber. Spray system can run a few minutes and then shut down. This transitory water spray can cool the samples quickly, creating heat shock conditions.
