This European Standard specifies fundamental techniques of computed radiography with the aim of enabling satisfactory
and repeatable results to be obtained economically. The techniques are based on the fundamental theory of the subject and
tests measurements. This document specifies the general rules for industrial computed X- and gamma radiography for flaw
detection purposes, using storage phosphor imaging plates (IP). It is based on the general principles for radiographic
examination of metallic materials on the basis of films (ISO 5579). The basic set-up of radiation source, detector and the
corresponding geometry shall be applied in agreement with ISO 5579 and the corresponding product standards as e.g. ISO
17636 for welding and EN 12681 for foundry. It does not lay down acceptance criteria of the imperfections. Digital
detectors provide a digital grey value image which can be viewed and evaluated on basis of a computer only. This practice
describes the recommended procedure for detector selection and radiographic practice. Selection of computer, software,
monitor, printer and viewing conditions are important but not in the main focus of this standard.
The procedure specified by this standard, provides the minimum requirements and practice which permits to expose and
acquire digital radiographs with equivalent sensitivity for detection of imperfections as film radiography and as specified in
ISO 5579.
