Abstract

Correlations between laboratory stress corrosion test data and field performance and data are done for the express purpose of demonstrating the validity of the laboratory data for use in component design and performance. Improved component performance and life-prediction is the primary goal of developing correlations between the laboratory and field performance. It is not sufficient to merely obtain data from a standard test and assume this will suffice. The purpose of this paper is to summarize the role of standardized tests, specialized tests, full-size component tests, the impact of the quality of field data, inability to match field conditions in the laboratory, and role of modeling in developing a high confidence laboratory-field correlation.
