摘要:紫外荧光老化试验箱QUv采用荧光紫外灯为光源,通过模拟自然阳光中的紫外辐射和冷凝,对材料
进行加速耐候性试验,以获得材料耐候性的结果。氙灯老化试验箱Q-Sum采用能模拟全阳光光谱的氙弧灯来再
现不同环境下存在的破坏性光波,用来进行老化的环境模拟和加速试验。QUV和Q-Sun同属加速老化和测试
材料光稳定性的设备,能提供快速且可重复的測试结果。本文论述了这两种仪器的特点和相关主要标准,并比
较了两者之间差别。

ABSTRACT: Ultraviolet aging tcst chamber QUV uses Fluorescent UV lamp as the light sourcc, and the acccleralcd
weathering test is carried out in order to obtain the results of the material weather resistance, by simulating the
ultraviolet radiation and condensation In sunlight. Xenon lamp aging test box Q-sun with a xenon are lamp can
simulatc the whole spectrum of sunlight reproduction to represent the destructive wave under dillcrcnt environments
which can be used for aging environment simulation and acceleraled test. Both of the two kinds of light aging test
quipments can provide rapid and repeatable test results. This paper discussed the characteristics and main standards
of QUV and Q-sun, and compared their applicable scope
