Rejection of Welded Connections According to EN ISO 10675: a New Approach to Increasing Objectivity

The currently applied criteria of identification of imperfections based on results of Radiographic Testing have no unambiguous description in regulatory documents. Therefore, there is a lack of coherence between opinions of the experts who are interpreting images on radiographic films .Authors suggest dividing images of imperfections into classes, each of which includes imperfections with similar projections on radiographs. This allows to simplify the identification procedure and to increase repeatability of results of the interpretation which is carried out by different experts independently.
