QUV系列试验箱可以模拟由阳光，雨水和露水造成的危害，QUV利用萤光紫外（UV）灯模拟阳光照射的效果，利用冷拟湿气模拟雨水和露水。被测试材料放置于一定温度下的光照和潮气交替的循环程序中进行测试。QUV用数天或数周的测试，即可重现户外数月到数年出现的危害，危害类型包括：褪色，变色，失光，粉化，裂痕，浑浊，泡化，脆化，强度衰退和氧化。QUV试验数据可以帮助你选择新材料，改进现在材料，以及评价配方变化如何影响产品的耐久性。在材料置于户外时的变化趋势上，QUV可以测出极佳的相关预测结果。

The QUV simulates the effect of sunlight with fluorescent ultraviolet(UV)lamps,while it simulates rain and dew with condensing hmidity ou water spray.in a few days or weeks,the QUVcan reproduce the damage that occurs over months or years outdoors.Types of damage include fading,color change,chalking,cracking,crazing,emdrittlement,strength loss......etc.Thetest data can help in the selection of new materials,the improvement of existing materials or the evaluation of how changes in formulations affect product durability.
