The QUV Accelerated Weathering Tester can reproduce the damage caused by sunlight, rain and dew. QUV uses ultraviolet fluorescent lamps to simulate sunlight, and simulates the effects of moisture by condensation or spraying. In just a few days or weeks, QUV can reproduce the damage that takes months or years to occur outdoors. The damage caused mainly includes fading, discoloration, brightness reduction, chalking, cracking, blurring, brittleness, strength reduction and oxidation. QUV test data is helpful in selecting new materials, improving existing materials, or evaluating component changes that affect product durability. QUV can accurately predict the changes that a product will encounter outdoors.
