Non-destructive testing - Image quality of radiographs - Part 4: Experimental evaluation of image quality values and image quality tables
This standard gives instructions for the determination of image quality values and image quality tables. If the IQI requirements from part 3 of this standard cannot be used, because, for example, the absorption coefficients of the IQI material and the inspected material differ by more than 30 %, test exposures arenecessary to determine acceptance of image quality values. The image quality values achieved by the test exposures are required for all exposures made under the same radiographic conditions.
Zerstörungsfreie Prüfung - Bildgüte von Durchstrahlungsaufnahmen - Teil 4: Experimentelle Ermittlung von Bildgütezahlen und Bildgütetabellen
Diese Norm gibt Anleitungen für die Bestimmung von Bildgütezahlen und Bildgütetabellen. Wenn die Bildgüteanforderungen nach Teil 3 dieser Norm nichtverwendet werden können, zum Beispiel weil sich die Absorptionskoeffizienten des BPK-Materials und des untersuchten Materials um mehr als 30 % unterscheiden sind Testaufnahmen notwendig, um die Annahme von Bildgütezahlen sicherzustellen. Die Bildgütezahlen, die durch Testaufnahmen erreicht wurden, werden für alle Durchstrahlungsaufnahmen gefordert, die unter denselben Durchstrahlungsbedingungen gemacht werden.
Essais non destructifs - Qualité d'image des radiogrammes - Partie 4: Evaluation expérimentale des indices de qualité d'image et des tables de qualité d'image
La présente norme donne les instructions nécessaires pour déterminer les indicesde qualité d'image et les tables de qualité d'image. S'il n'est pas possible d'appliquer à l'IQI les prescriptions de la troisième partie de la présente norme, parce que, par exemple, les coefficients d'absorption du matériau de l'IQI et du matériau inspecté diffèrent de plus de 30 %, il est nécessaire d'utiliser des expositions expérimentales pour déterminer des indices de qualitéd'image acceptables.

EN 462-4:1994 is a standard published by the European Committee for Standardization (CEN). Its full title is "Non-destructive testing - Image quality of radiographs - Part 4: Experimental evaluation of image quality values and image quality tables". This standard covers: This standard gives instructions for the determination of image quality values and image quality tables. If the IQI requirements from part 3 of this standard cannot be used, because, for example, the absorption coefficients of the IQI material and the inspected material differ by more than 30 %, test exposures arenecessary to determine acceptance of image quality values. The image quality values achieved by the test exposures are required for all exposures made under the same radiographic conditions.
