The World's Most Widely Used Weathering Tester™
Test plastics, coatings, and other materials for durability when exposed to outdoor sunlight, heat, and water
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.
The QUV accelerated weathering tester is the simplest, most reliable, and easiest-to-use weathering tester available. QUV and Q-SUN
xenon arc testers are complimentary test types - see QUV and Q-SUN: A Comparison for further information. With thousands of testers in use worldwide, it is the world's most widely-used weathering tester.
UV light is responsible for almost all photodegradation of durable materials exposed outdoors. The QUV tester’s fluorescent lamps simulate the critical short-wave UV region of the solar spectrum and realistically reproduce the physical property damage caused by sunlight. Types of damage include color change, gloss loss, chalking, cracking, crazing, hazing, blistering, embrittlement, strength loss, and oxidation.
Dew, not rain, is responsible for most of the wetness that occurs in outdoor exposure. The QUV test chamber's condensation system realistically simulates dew and accelerates its effect using elevated temperature.
The condensation process automatically purifies the ordinary tap water used in the system. This is because the process of evaporating and condensing the water onto the specimens is actually a distillation process, which removes all impurities. See the QUV Brochure for details.
The QUV tester conveniently accommodates up to 48 specimens (75 × 150 mm) and complies with a wide range of international, national, and industry specifications, ensuring the reliability and reproducibility of your test program. Visit our standards search for more information.
