Annotation of standard text IEC 61267-ed.3.0 :
IEC 61267:2025 applies to test procedures which, for the determination of characteristics of systems or components of medical diagnostic X-ray equipment, require well-defined X-ray radiation conditions. This document deals with methods for generating X-ray radiation conditions which can be used under test conditions typically found in test laboratories or in manufacturing facilities for the determination of characteristics of medical diagnostic X-ray equipment. IEC 61267:2025 cancels and replaces the second edition published 2005. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) removing former Annex C “Measurement of the practical peak voltage”; b) inserting informative “Tabulated values for the squared signal-to-noise ratio per air kerma (SNR2in)” and normative “Additional X-ray radiation conditions as used in mammography and determination of the corresponding nominal aluminium half-value layers”; c) revision of X-ray radiation conditions; d) new method for verification of X-ray radiation conditions; e) change of term definitions. LIEC 61267:2025 sapplique aux procedures dessais qui, pour la determination des caracteristiques des systemes ou des composants des equipements a rayonnement X de diagnostic medical, necessitent des conditions de rayonnement X bien definies. Le present document traite des methodes de generation de conditions de rayonnement X qui peuvent etre utilisees dans les conditions dessais generalement rencontrees dans les laboratoires dessai ou dans les installations de fabrication pour la determination des caracteristiques des equipements a rayonnement X de diagnostic medical. LIEC 61267:2025 annule et remplace la deuxieme edition parue en 2005. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) suppression de lancienne Annexe C "Mesure de la tension de crete pratique"; b) insertion dune Annexe C informative "Valeurs compilees du rapport signal sur bruit au carre par kerma dans lair (SNRin2 )" et dune Annexe D normative "Conditions du rayonnement X supplementaires utilisees en mammographie et determination des couches de demi-attenuation en aluminium nominales correspondantes"; c) revision des conditions de rayonnement X; d) nouvelle methode de verification des conditions de rayonnement X; e) modification des definitions des termes.
