Potential mapping is a widely used inspection method for detection of ongoing corrosion in reinforced concrete structures. Usually based on the results from potential mappings, further inspection strategies and repair actions are scheduled. Unfortunately the probability of detection (PoD) of the method is an unknown factor. To obtain values for the PoD of potential mapping, it is necessary to compare potential measurements of reinforced structures with their true corrosion condition state. The true corrosion condition state is only identifiable by replacement of concrete cover. In general, owners will not agree to open a whole structure for evaluating the accuracy of an inspection method. Therefore, in this research, an approach based on numerical models with known condition state is pursued.
