So far, existing formats for non-destructive examination (NDE) data are specific to a given system and method, and do not include all the necessary information to allow an exchange of the data. This technical report defines a format model for NDE data organisation, in order for them to be exchanged (transmission, comparison, remote computer-processing) and computer-processed (traceability, archiving, retrieval, signal processing, comparative analysis). This format is independent of the used system and method. It applies to digital data issued from the following NDE methods : radiology, ultrasonics, eddy currents, penetrant testing, magnetic particle testing, leak testing, acoustic emission, visual inspection. Other methods (thermography, Barkhausen noise, shearography, microwave testing, ...) may comply with this model with additional definitions required to ensure satisfactory performance. Interpretation of data is outside the scope of this technical report.
