Accelerated weathering tester, Q8 , is designed to simulate the weather mix with UV light, temperature and moisture conditions. The tests are intended to reproduce the damage caused by sunlight, rain and condensed surface moisture or dew. Types of damage include color change, gloss loss, chalking, cracking, hazing, embrittlement, and strength loss.
With programmable controller that can program the rain, UV light and temperature. With cycling control of light and moisture at controlled temperatures.
The moisture includes both condensing humidity, to simulate dew, and water sprays. The light in the chamber is created by specially-designed fluorescent UV bulbs to simulate the effects of sunlight.
