In this paper a benchmark definition is proposed for the qualification of the performance of different kind of eddy current testing (ECT) probes. The benchmark problem is basically defined by the description of several experiments. The solution of the proposed benchmark problem is thought to be a free format presentation that discusses the results of the defined benchmark experiments. The benchmark experiments are designed to give information on the sensitivity, application frequency range, lift-off noise, tilting noise, etc. of the tested ECT probe. At the end of the paper a preliminary example is presented for the solution of some parts of the proposed benchmark problem.
