The GJB 4.11-1983 standard is a salt spray test method for ship electronic equipment, which aims to determine the corrosion resistance of electronic components in a salt fog environment. The standard requires the test equipment to have anti-salt fog corrosion materials, which can provide uniform and stable test conditions, and have adjustment and observation functions. The test process requires that the salt fog is not directly sprayed on the sample, nor does it allow water droplets to fall on the sample, so as to effectively evaluate the mass and uniformity of the protective layer.
