TITLE Test Planning and Design: ASTM Manual on Corrosion Tests and Standards and Interpretation AUTHOR(S) John W. Spence, Stephen D. Cramer, and Fred H. Haynie PERFORMING ORGANIZATION NAME AND ADDRESS EMAP Center U.S. Environmental Protection Agency U.S. Department of Interior, Bureau of Mines Albany Research Center, Albany, OR 97321 SPONSORING AGENCY NAME AND ADDRESS Office of Research and Development U.S. Environmental Protection Agency EMAP Center Research Triangle Park, NC 27711 ABSTRACT Corrosion tests are an important evaluative tool when using materials for scientific, industrial, engineering, consumer, and aesthetic purposes. Tests have been used to help transform natural resources into construction materials for buildings, bridges, spacecraft, monuments, computers, medical implants, automobiles, chemical plants, drilling and mining equipment, and manufacturing facilities--all of which have an impact on society. Corrosion tests evaluate a range of material degradation processes, which include mechanically assisted corrosion and wear/corrosion synergism. Corrosion tests examine the performance of materials, evaluate using alternate materials, develop strategies for protection of materials, and obtain corrosivity information on specific environments. This chapter will provide an overview for and a generalized approach to planning corrosion tests. While testing of metallic materials is the primary focus of this book, the general approach for planning corrosion tests also applies to environmental testing of nonmetallic materials, such as paints, plastics, ceramics, stone, and fibers.
