UNE-EN ISO 16371-2:2018

This International Standard specifies fundamental techniques of computed radiography with the aim ofenabling satisfactory and repeatable results to be obtained economically. The techniques are based onthe fundamental theory of the subject and tests measurements. This document specifies the generalrules for industrial computed X- and gamma radiography for flaw detection purposes, using storagephosphor imaging plates (IP). It is based on the general principles for radiographic examination ofmetallic materials on the basis of films (ISO 5579). The basic set-up of radiation source, detector andthe corresponding geometry shall be applied in agreement with ISO 5579 and the correspondingproduct standards as e.g. ISO 17636 for welding and EN 12681 for foundry. It does not lay downacceptance criteria of the imperfections. CR systems provide a digital grey value image which can beviewed and evaluated on basis of a computer only. This practice describes the recommended procedurefor detector selection and radiographic practice. Selection of computer, software, monitor, printer andviewing conditions are important but not in the main focus of this standard.The procedure specified by this standard, provides the minimum requirements and practice whichpermits to expose and acquire digital radiographs with equivalent sensitivity for detection ofimperfections as film radiography and as specified in ISO 5579. Some application standards, as e.g.EN 16407 may require different and less stringent practice conditions.
