本试验设备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。
The test equipment simulates corrosion test in man-made environment, which is used to test the quality of metal materials with or without corrosion protection. It is suitable for rapid analysis of discontinuity, hole and damage in organic and inorganic coatings. In addition, for the purpose of quality control, it can be used in the test of coatings with the same coating. Salt spray test is especially suitable for detecting discontinuities in some metals, organic, anodic oxidation and conversion coatings, such as small holes and other defects.
