Overview

This part of ISO 19232 gives instructions for the determination of image quality values and image quality tables. If the image quality requirements in accordance to 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 are necessary 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. This document (EN ISO 19232-4:2013) has been prepared by Technical Committee CEN/TC 138 "Non-destructive testing", the secretariat of which is held by AFNOR (France) in collaboration with Technical Committee ISO/TC 135 "Non-destructive testing". The responsible German body involved is Working Committee NA 062-08-22 AA "Durchstrahlungsprüfung und Strahlenschutz" ("Radiation methods and radiation protection") of the Materials Testing Standards Committee (NMP) at DIN. DIN EN ISO 19232, "Non-destructive testing - Image quality of radiographs" consists of: - Part 1: Determination of the image quality value using wire-type image quality indicators - Part 2: Determination of the image quality value using step/hole-type image quality indicators - Part 3: Image quality classes - Part 4: Experimental evaluation of image quality values and image quality tables - Part 5: Determination of the image unsharpness value using duplex wire-type image quality indicators
