The scope of this paper is to define a methodology for building robust PoD curves from numerical modelling. First, an experimental database will be created in a laboratory scenario. A representative sample of inspectors with different certification levels in NDT method will be employed. Multiple inspections will be carried out to include the human influence in the MAPOD calculation. In addition, this study will take into account the impact of using different devices in the High Frequency Eddy Current method (HFEC). Then, a simulation model is created taking into consideration the main uncertainties due to human and device factors. These uncertainties are identified and quantified by the observation of experimental NDT inspection. Then, statistical distributions of these uncertainties are derived and used as inputs of the simulation model. Finally, the simulation PoD model will be compared and validated with the experimental results developed in the laboratory scenario. This comparison provided encouraging results to replace or complete experimental tests by simulation.
