N2 - The reliable and economic condition control of our ageing infrastructure is the major task for engineers in practice. One important step is the inspection of ongoing corrosion with potential mapping. This measurement delivers fundamental information for the probabilistic service life prediction. Due to the lack of knowledge about the accuracy of corrosion detection the combination of inspection data and probabilistic service life prediction is difficult to perform. The aim of this paper is the analysis of the probability of detection (PoD) of potential mapping as a main descriptor of the accuracy for qualitative inspection methods. For determining the PoD, the true corrosion condition state has to be compared with the measurement results. As no owners will agree to open a structure for evaluating the PoD of potential mapping a numerical approach is pursued.
