本试验设备主要用于确定装备上的材料和表面涂层耐受酸性大气影响的能力，试验适用于可能在酸性大气地区（如工业区或燃烧设备的废气附近）储存或使用的装备。也可以用于模拟人造环境中的腐蚀试验，用于检验金属材料有或无防腐蚀保护比较质量的方法；适合于快速分析有机和无机涂层中的不连续性、孔和损坏等现象的防腐蚀试验，此外，为质量控制的目的，能在涂有相同涂料的试样之间进行比较；盐雾试验特别适用于检测某些金属、有机、阳极氧化和转化涂层中的不连续性，如小孔和其他缺陷；设备不适用于评价硫化氢的影响。
This equipment is mainly used to determine the material and surface coatings on the equipment's ability to withstａnd the effects of acid atmosphere. The test is suitable for equipment that may be stored or used in acidic atmosphere areas, such as industrial areas or near the exhaust gas of combustion equipment. It can also be used to simulate corrosion tests in man-made environments and to test the quality of metal materials with or without corrosion protection. It is suitable for rapid analysis of discontinuity, pore and damage in organic and inorganic coatings. In addition, for the purpose of quality control, it can be used to test the same coatings. Salt spray test is especially suitable for detecting discontinuities in some metals, organic, anodic oxidation and conversion coatings, such as holes and other defects; equipment is not suitable for evaluating the effect of hydrogen sulfide.
