Spectral Power Distribution (SPD) for QUV testers with TUV-421 Fluorescent LampsDownload File

Sunlight, heat, and moisture cause millions of dollars of material damage every year. The QUV® accelerated weathering tester exposes materials to alternating cycles of UV light and moisture at controlled, elevated temperatures. In a few days or weeks...

Sunlight, heat, and moisture cause millions of dollars of material damage every year. The QUV accelerated weathering tester reproduces the damage caused by sunlight, rain and dew. In a few days or weeks, the QUV can generate the same degradation tht ...

Condensation is an excellent way to simulate the moisture attack that materials experience outdoors. High-humidity condensing environments can be generated in QCT, QUV, Q-SUN and Q-FOG testers. However, not all condensation testing is the same. There...

Testing for Light Stability in Retail & Residential EnvironmentsAbstract Indoor products may be subjected to a wide range of interior lighting environments. These environments include residential incandescent, commercial fluorescent, and ind...

Your exposure application determines which type of UV lamps should be used. The QUV accelerated weathering tester's lamps typically emit mainly ultraviolet (UV) light rather than visible or infrared (IR) light. All lamps are electrically equivalent t...
