For realistic and accurate description of the corrosion progress in reinforced concrete structures, the inspection results from detection of on-going corrosion are of vital importance, in particular for the probabilistic service life prediction. The crucial factor of the combination of inspection data and probabilistic service life prediction is the knowledge about the accuracy of the measurement method itself. The Probability of Detection (PoD) is a main descriptor of the accuracy of qualitative inspection methods. Commonly, a PoD curve describes the rate of detecting a defect with given defect size s, PoD(s). In the case of potential mapping, the defect size is the anode area. In this research, an approach based on numerical models is pursued to obtain a PoD of potential mapping for small anode areas. It is expected that through the integration of the potential mapping data the condition of the structure and correspondingly the service life time can be predicted more accurately.     «
