Method 101 is the Salt Atmosphere (Corrosion) test. Specimens are subjected to a fine mist of salt solution to evaluate the effectiveness and quality of protective coatings and finishes on metals. Originally proposed as an accelerated laboratory corrosion test simulating the effects of seacoast atmospheres.
Experience has shown that there is seldom a direct relationship between resistance to salt atmosphere corrosion and resistance to corrosion in other media. The test has useful purposes when utilized with full recognition of its deficiencies and limitations.
This test is commonly used for screening purposes to evaluate component parts and subassemblies of electrical and electronic equipment for resistance to salt-laden marine environments.
