Requirements for relative humidity control of xenon lamp aging test chamber

For many materials, relative humidity (RH) control is critical, and most test standards have requirements for relative humidity control. The rotary drum type (water-cooled) xenon lamp aging test chamber and the flat type (water-cooled) xenon lamp aging test chamber should be equipped with a relative humidity control system. Accurate control of relative humidity is difficult because a large amount of air must flow in the test chamber to maintain the test temperature. To control the relative humidity, the temperature of the test chamber air must be monitored. The flat-type xenon lamp aging test chamber's accurate relative humidity control system (patented by Q-Panel Corporation of the United States) exceeds the requirements of ISO, ASTM, AATCC and SAE test standards and is widely used in outdoor exposure testing.
