The Solar Radiation Test is a manual simulated environmental test (the name of the equipment on the market is a xenon weather resistant test chamber) that simulates the effects of exposure to solar radiation during use on the ground or in the lower atmosphere or during unshielded storage. The effect of solar radiation on the product is mainly caused by heating and photochemical effects. The heating effect is mainly generated by the mid-infrared spectrum of solar radiant energy, which mainly causes short-term high temperature and local overheating of the product, causing some temperature-sensitive components to fail, mechanical damage of structural materials and overheating damage of insulating materials. The photochemical effect is mainly generated by the ultraviolet spectrum of the solar radiant energy. The optical energy provided by the ultraviolet spectroscopy is sufficient to excite the organic material molecules to cause it to break, degrade or interact, thereby aging and deteriorating the material. When solar radiation is combined with climatic factors such as temperature and humidity, its damage is more obvious. The most easily found damages are surface damage such as deformation, discoloration, tarnishing, chalking, cracking, etc. At the same time, the inherent mechanical and electrical properties are also reduced, thereby reducing the use value of the material and even scrapping it. The impact of solar radiation on products cannot be ignored. Therefore, solar radiation tests should be arranged in the development and production of materials, weapons and equipment to improve or verify their adaptability to the exposed environment of sunlight.
