Accelerated QUV Testing
What is QUV testing? Basically it means accelerated weather testing to reproduce the damaging effects of UV sunlight and moisture on polymer coatings.
Tests are conducted in a laboratory environment; a high intensity chamber is designed to accelerate the effects of exposure to the elements and the damage typically caused to the surface over the span of years - but it takes only days or weeks to reproduce these results.
Using the standard ASTM testing methods, samples are placed in the QUV testing chamber and are bombarded with sunlight spectrum UV light in alternating dry and wet cycles and elevated temperatures.
Although there is no established direct correlation between hourly exposure in a QUV tester and years of actual exterior sunlight exposure, QUV is the industry accepted method of predicting polymer performance throughout years of exterior exposure service.
Two samples of aquaBRIGHT™ Pool Finish by ecoFinish™
Sample on the left was exposed to 3000 hours of QUV testing. Sample on the right was kept in the dark as a comparative standard. The result of the 3000 hour test revealed no visual indication of color change or gloss loss from the damaging effects of UV exposure.
