WITH THE PUBLICATION of the first edition of Corrosion Tests and Standards-Interpretation and Application (Manual 20), this chapter concluded with the prediction that future work in the study and characterization of stress corrosion cracking (SCC) of engineering alloys would be directed to more quantitative information based on improved test control, procedures, and techniques to better serve the engineering community, and improved modeling and life prediction techniques. This same theme has been reiterated in the most recent ASTM sponsored conference  by Wei, who stated that the community should take a role in development of quantitative methodologies for assurance of reliability and continued safety of engineered systems . In that same conference, Staehle  elaborated on a technique for predicting SCC using a corrosion-based design approach (CBDA), and a location for analysis matrix (LAM). More quantitative methodologies and SCC prediction are still recognized as desired entities. The initial publication of this chapter compiled a historical perspective of the SCC phenomenon as well as discussion of testing standards and techniques, and evaluation and interpretation of test results. To that end, the narrative included in the first edition is essentially preserved in the current chapter with additions included based on research and development since the first publication.
