Anotation

IEC 61676:2023 specifies the performance requirements of instruments as used in the non-invasive measurement of X-RAY tube voltage up to 150 kV and the relevant compliance tests. This document also describes the method for calibration and gives guidance for estimating the uncertainty in measurements performed under conditions different from those during calibration. Applications for such measurement are found in diagnostic radiology including mammography, computed tomography (CT), dental radiology and radioscopy. This document is not concerned with the safety aspect of such instruments. The requirements for electrical safety applying to them are contained in IEC 61010-1. IEC 61676:2023 cancels and replaces first edition published in 2002, Amendment 1:2008. This edition constitutes a technical revision. It includes an assessment of the combined standard uncertainty for the performance of a hypothetical instrument for the non-invasive measurement of the tube high voltage (in Annex A) which replaces Annex A of the edition 1.1 titled "Recommended performance criteria for the invasive divider". The contents of the corrigendum of January 2024 have been included in this copy. LIEC 61676:2023 specifie les exigences de performance des appareils utilises dans le mesurage non invasif de la tension du tube radiogene jusqu’a 150 kV et les essais de conformite applicables. Le present document decrit egalement la methode d’etalonnage et donne des recommandations pour l’estimation de l’incertitude des mesurages realises dans des conditions differentes de celles rencontrees au cours de l’etalonnage. Les applications pour un tel mesurage se rencontrent dans la radiologie de diagnostic y compris la mammographie, la tomodensitometrie, la radiologie dentaire et la radioscopie. Le present document ne traite pas des aspects securite de tels appareils. Les exigences pour la securite electrique s’appliquant a ceux-ci figurent dans l’IEC 61010-1. LIEC 61676:2023 annule et remplace la premiere edition parue en 2002 et lAmendement 1:2008. Cette edition constitue une revision technique. Elle comprend une evaluation de l’incertitude type composee pour les performances d’un appareil hypothetique pour le mesurage non invasif de la haute tension du tube (a l’Annexe A) qui remplace l’Annexe A de l’edition 1.1 intitulee "Criteres de performances recommandes pour le diviseur invasif". Le contenu du corrigendum de janvier 2024 a ete pris en consideration dans cet exemplaire.
