EN 462-4:1994

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.
