Accelerated QUV Testing
QUV accelerated weather testing reproduces the damaging effects of UV sunlight and moisture on polymer coatings in a laboratory environment. The test accelerates the damage that would normally occur over the span of years to that of only days or weeks in the high-intensity chamber. Using standard ASTM testing methods, samples placed in the QUV testing chamber are bombarded with sunlight spectrum UV light, in alternating dry and wet cycles, and elevated temperatures. Although there is no established direct correlation between hours exposure in a QUV tester and years of actual exterior sunlight exposure, QUV is an industry accepted method of predicting polymer performance throughout years of exterior exposure service.
