Electrical and loading characteristics of X-ray tube assemblies for medical diagnosis

IEC 60613:2010 applies to X-ray tube assemblies either with a rotating anode X-ray tube or a stationary anode X-ray tube, intended for use in medical diagnosis. For an X-ray tube head, its X-ray tube assembly aspects are also within the scope. IEC 60613:2010 covers performance-related definitions and conditions of electrical and loading characteristics of X-ray tube assemblies in relation to their behaviour during and after energization and, where appropriate, methods of presentation and measurement of these characteristics. This International Standard is therefore relevant for the manufacturer and the responsible organization. This third edition cancels and replaces the second edition of IEC 60613, published in 1989. It constitutes a technical revision. This third edition has been adapted to apply to the present technology.

Caractéristiques électriques et de charge des gaines équipées pour diagnostic médical

La CEI 60613:2010 s'applique aux gaines équipées à tube radiogène à anode tournante ou à tube radiogène à anode fixe, destinées à être utilisées pour le diagnostic médical. Pour une tête de tube radiogène, ses aspects concernant le tube radiogène relèvent également du domaine d'application. La CEI 60613:2010 comprend les définitions et les conditions de performance des caractéristiques électriques et de charge des gaines équipées par rapport à leur comportement pendant et après la mise sous tension avec, si besoin, des méthodes de présentation et de mesure de ces caractéristiques. La présente Norme Internationale est de ce fait utile pour le fabricant et pour l'organisme responsable. Cette troisième édition annule et remplace la deuxième édition de la CEI 60613 publiée en 1989, dont elle constitue une révision technique. Cette troisième édition a été adaptée afin d'appliquer les technologies actuelles.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60613 has been prepared by subcommittee 62B: Diagnostic
imaging equipment, of IEC technical committee TC 62: Electrical equipment in medical
practice.
This third edition cancels and replaces the second edition of IEC 60613, published in 1989. It
constitutes a technical revision. This third edition has been adapted to apply to the
present technology.
