Reliability investigation of NDE signals

  • The reliability investigations are dedicated to throw light on the performance of the NDE system with respect to the required aim. This is especially of interest when digitized and processed signals are involved where it becomes hard to assess whether the quality of the system has raised or not. Three different ways to investigate reliability of NDE signals will be described. The first way of investigation, the performance demonstration, is preferred e.g. in the US American nuclear power industry. This is an integral consideration of the non destructive test as a system where the whole NDE system is packed in a black box and only the input in terms of the real existing flaws in the component is considered and compared to the output in terms of the indications of the human inspector or of the automated system. The second – the European tradition – relies on a standardized description of physical/technical parameters of the NDE system which are preconditions for successful systemThe reliability investigations are dedicated to throw light on the performance of the NDE system with respect to the required aim.

The second – the European tradition – relies on a standardized description of physical/technical parameters of the NDE system which are preconditions for successful system performance. An example for such a standardized set of performance parameters is given in the recently released standard about Xray film digitization CEN EN 14096. The third approach – the modular conception – is a marriage of both: The signal chain is cut into main modules. Each module is assessed in a most appropriate individual way e.g. via modeling calculations. The single results are joint together according to the reliability of the subsystems. Separating criteria for the system were proposed through a reliability formula developed during a series of European-American workshops on NDE reliability. Examples of all three approaches will be given.zeige mehrzeige weniger
