CORROSION TESTS ARE performed to provide information on material degradation in specific environments, information that is not available from other sources. Corrosion testing can be divided into two broad categories, electrochemical and nonelectrochemical. Within these categories, test results are presented in a number of ways, ranging from numerical output to qualitative examination of the test specimen. Both types of data are represented in each category. A very complete listing of data formats for collection and compilation for computerized databases is presented in ASTM G 107, Guide for Formats for Collection and Compilation of Corrosion Data for Metals for Computerized Database Input. The information in that standard includes a significant portion of the type of test data that might be recorded during corrosion testing. Since required data are test-dependent, not every test would include all of the data listed, but the standard does provide a reasonable, first pass checklist and should be used to ensure that needed information is not overlooked.
