Abstract

This paper proposes a general scheme for the design of test programs to assess corrosion resistance in a meaningful way. Any metallic material or coated metal product that is to be used in a specific set of conditions may suffer corrosion. The chemical and physical factors of the service application, together with the metallic material, determine the type and extent of corrosion damage encountered. Corrosion science can be used to specify the critical environmental factors in the test method.

The test program can provide results that are important for the following: the development of new materials and coatings; the choice of protective systems for new equipment designs; the development of quality control programs and quality acceptance tests. Statistical methods are essential to determine the significance levels of results and the corresponding material specifications.
