氙灯老化测试
造成材料老化的主要因素是阳光和潮湿，太阳光是造成很多材料降解的一个主要因素。降解的类型，如物理性能下降、粉化、开裂、起皮、褪色及颜色变化等与材料的敏感度和光谱有关，每种材料对光谱响应不同。对于耐久材料，如大部分涂料和塑料，短波紫外线是造成聚合物老化的主要原因。然而，对于不是特别耐久的材料，长波紫外线甚至短波可见光是造成其破坏的主要因素。
氙灯气候试验箱可以模拟由阳光、雨水和露水造成的危害，利用氙灯模拟阳光照射的效果，利用冷凝湿气模拟雨水和露水，被测材料放置在一定温度下的光照和潮气交替的循环程序中进行测试，用数天或数周的时间即可重现户外数月乃至数年出现的危害，人工加速老化试验数据可以帮助选择新材料，改造现有材料，以及评价配方的变化是如何影响产品的耐久性的。

Xenon lamp aging test
The main factors causing material aging are sunlight and humidity, and sunlight is a major factor causing degradation of many materials. The type of degradation, such as degradation of physical properties, pulverization, cracking, peeling, fading and color change, is related to the sensitivity and spectrum of materials, and each material has different spectral response. For durable materials, such as most paints and plastics, short wave ultraviolet radiation is the main cause of polymer aging. However, for materials that are not particularly durable, long wave ultraviolet and even short wave visible light are the main factors causing damage.
The xenon lamp climate test chamber can simulate the hazards caused by sunlight, rain and dew. The xenon lamp can be used to simulate the effect of sunlight, and the condensed moisture can be used to simulate rain and dew. The tested materials are placed in a cycle of alternating light and moisture at a certain temperature for testing. The outdoor hazards of months or even years can be reproduced in a few days or weeks. The artificial accelerated aging test data can help select new materials, Modification of existing materials and evaluation of how changes in formulation affect product durability.
