A well-known test is the salt spray test. Translation of laboratory data from a single test program to predict service performance under a variety of conditions should be avoided. These tests provide a measure for the adhesion of a coating to its substrate paint or zinc coating. The corrosion behavior of materials is often a primary factor for the design and function of welded joints.
