These models give approximate life estimates based on calculated current densities and electrochemical potentials. Numerically predicted results are compared with experimental data for typical roof fastener/deck systems. INTRODUCTION Materials are selected during the design phase of a project based upon past history of performance in the anticipated environment. Material specifications are typically limited to certain grades of
