QUV Accelerated Weathering Tester

The QUV accelerated weathering tester reproduces the damage caused by natural sunlight, rain, and dew. In a few days or weeks, the QUV tester can reproduce the damage that occurs over months or years outdoors. To simulate outdoor weathering, the QUV accelerated weathering tester exposes materials to alternating cycles of ultraviolet (UV) light and moisture at controlled, elevated temperatures. It simulates the effects of natural sunlight and artificial irradiance using special fluorescent UV lamps in the UVA, UVB, and UVC portions of the spectrum. It simulates dew and rain with condensing humidity and/or water spray.

QUV Fluorescent UV lamps

Fluorescent UV lamps are inherently more stable than other types of lamps, including xenon arc lamps. The spectral irradiance (or spectral power distribution, SPD) does not change with lamp aging, even up to 8,000 hours. This gives more reproducible test results, fewer lamp changes, and lower operational costs.
