Medical electrical equipment - Part 2-43: Particular requirements for the basic safety and essential performance of X-ray equipment for interventional procedures

IEC 60601-2-43:2022 applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of both FIXED and MOBILE X RAY EQUIPMENT declared by the MANUFACTURER to be suitable for RADIOSCOPICALLY GUIDED INTERVENTIONAL PROCEDURES, hereafter referred to as INTERVENTIONAL X-RAY EQUIPMENT. Its scope excludes, in particular:
- equipment for RADIOTHERAPY;
- equipment for COMPUTED TOMOGRAPHY;
- ACCESSORIES intended to be introduced into the PATIENT;
- mammographic X RAY EQUIPMENT;
- dental X RAY EQUIPMENT.
INTERVENTIONAL X-RAY EQUIPMENT declared by the MANUFACTURER to be suitable for RADIOSCOPICALLY GUIDED INTERVENTIONAL PROCEDURES, which does not include a PATIENT SUPPORT as part of the system, is exempt from the PATIENT SUPPORT provisions of this document.
If a clause or subclause is specifically intended to be applicable to INTERVENTIONAL X-RAY EQUIPMENT only, or to ME SYSTEMS only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to INTERVENTIONAL X-RAY EQUIPMENT and to ME SYSTEMS, as relevant.
IEC 60601-2-54 applies only with regards to the cited subclauses; non-cited subclauses of IEC 60601-2-54 do not apply.
IEC 60601-2-43:2022 cancels and replaces the second edition published in 2010, Amendment 1:2017 and Amendment 2:2019. This edition constitutes a technical revision.
This edition includes editorial and technical changes to reflect the IEC 60601-1:2005/AMD2:2020 and IEC 60601-2-54:2022. It also contains corrections and technical improvements. Significant technical changes with respect to the previous edition are as follows:
a) a new specific term DOSIMETER is introduced to replace the general term DOSEMETER as in IEC 60601-2-54:2022;
b) several terms and definitions that are moved from IEC TR 60788:2004 to 201.3 of IEC 60601-2-54:2022 are also referenced from IEC 60601-2-54:2022.
c) the collateral standards IEC 60601-1-11:2015, IEC 60601-1-11:2015/AMD1:2020, IEC 60601-1-12:2014 and IEC 60601-1-12:2014/AMD1:2020 are applicable if MANUFACTURER so declares;
d) the former subclause 201.11.101 “Protection against excessive temperature of X-RAY TUBE ASSEMBLIES” is removed since covered by IEC 60601-1:2005, IEC 60601-1:2005/AMD1:2012, IEC 60601-1:2005/AMD2:2020 and IEC 60601-2-28:2017, and the former subclause 201.11.102 is renumbered as 201.11.101, as in IEC 60601-2-54:2022;
e) to adopt changes in subclause 7.8.1 “Colours of indicator lights” in IEC 60601 1:2005/AMD2:2020, clarification of requirements is provided in 201.7.8.1 to avoid conflicts with requirements of indicator lights stipulated for X-RAY EQUIPMENT, as in IEC 60601-2-54:2022;

- les ACCESSOIRES destinés à être introduits dans le corps du PATIENT;
- les APPAREILS de mammographie A RAYONNEMENT X;
- les APPAREILS de radiographie dentaire A RAYONNEMENT X.
Les APPAREILS A RAYONNEMENT X D’INTERVENTION déclarés par le FABRICANT comme étant adaptés aux INTERVENTIONS GUIDEES PAR RADIOSCOPIE, qui n’incluent pas le SUPPORT PATIENT sont exemptés des dispositions du présent document applicables au SUPPORT PATIENT.
Lorsqu’un article ou un paragraphe est spécifiquement destiné à être applicable uniquement aux APPAREILS A RAYONNEMENT X D’INTERVENTION ou uniquement aux SYSTEMES EM, le titre et le contenu de l’article ou du paragraphe concerné l'indiquent. Si tel n'est pas le cas, l'article ou le paragraphe s'applique à la fois aux APPAREILS A RAYONNEMENT X D’INTERVENTION et aux SYSTEMES EM, selon le cas.
L'IEC 60601-2-54 s'applique uniquement en ce qui concerne les paragraphes cités; les paragraphes non cités de l'IEC 60601-2-54 ne s'appliquent pas.
L'IEC 60601-2-43:2022 annule et remplace la deuxième édition parue en 2010, l'Amendement 1:2017 et l'Amendement 2:2019. Cette édition constitue une révision technique.
Cette édition inclut des modifications rédactionnelles et techniques pour refléter les modifications dans l’IEC 60601 1:2005/AMD2:2020 et l’IEC 60601-2-54:2022. Elle contient également des corrections et des améliorations techniques. Les modifications techniques majeures par rapport à l’édition précédente sont les suivantes:
a) un nouveau terme spécifique DOSIMETRE est utilisé pour remplacer le terme général DOSIMETRE comme dans l’IEC 60601-2-54:2022;
b) plusieurs termes et définitions de l’IEC TR 60788:2004 déplacés dans l’Article 201.3 de l’IEC 60601-2-54:2022 sont aussi référencés à partir de l’IEC 60601-2-54:2022;
c) les normes collatérales IEC 60601-1-11:2015, IEC 60601-1-11:2015/AMD1:2020, IEC 60601-1-12:2014 et IEC 60601-1-12:2014/AMD1:2020 sont applicables lorsque le FABRICANT les déclare telles quelles;
d) l’ancien paragraphe 201.11.101 "Protection contre les températures excessives des GAINES EQUIPEES" est supprimé car il est couvert par l’IEC 60601-1:2005, l’IEC 60601-1:2005/AMD1:2012, l’IEC 60601-1:2005/AMD2:2020 et l’IEC 60601-2-28:2017 et l’ancien paragraphe 201.11.102 est renuméroté en 201.11.101, comme dans l’IEC 60601-2-54:2022;
e) pour adopter les modifications du paragraphe 7.8.1 "Couleurs des voyants lumineux" de l’IEC 60601-1:2005/AMD2:2020, une clarification des exigences est fournie en 201.7.8.1 pour éviter les contradictions avec les exigences des voyants lumineux stipulées pour les APPAREILS A RAYONNEMENT X, comme dans l’IEC 60601-2-54:2022;
f) une explication du terme PERFORMANCE ESSENTIELLE est donnée à l’Annexe AA pour mettre l’accent sur les performances de la fonction clinique dans les CONDITIONS NORMALES et les CONDITIONS DE PREMIER DEFAUT.

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.
This redline version of the official IEC Standard allows the user to identify the changes made to
the previous edition IEC 60601-2-43:2010+AMD1:2017+AMD2:2019 CSV. A vertical bar appears
in the margin wherever a change has been made. Additions are in green text, deletions are in
