Specifies methods for identifying the most important characteristics of diagnostic X-ray equipment and the relevant associated test methods, so that the characteristics can be stated in a standardized way to facilitate comparison between devices. This Standard is identical with and reproduced from IEC 1267:1994.

This International Standard applies to test procedures which, for the determination of characteristics of systems or components of medical diagnostic X-RAY EQUIPMENT, require well-defined RADIATION CONDITIONS.Except for mammography, this standard does not apply to conditions where discontinuities in radiation absorption of elements are deliberately used to modify properties of the RADIATION BEAM (for example by rare earth filters).Speed measurements of screen-film systems are not included in this standard. This topic will be covered by an ISO standard.
