Medical electrical equipment - Medical electron accelerators - Functional performance characteristics
This International Standard applies to medical ELECTRON ACCELERATORS when used, for therapy purposes, in human medical practice. This standard applies to medical ELECTRON ACCELERATORS which deliver a RADIATION BEAM of either X-RADIATION or ELECTRON RADIATION with NOMINAL ENERGIES in the range 1 MeV to 50 MeV at maximum ABSORBED DOSE RATES between 0,001 Gy s-1 and 1 Gy s-1 at 1 m from the RADIATION SOURCE and at NORMAL TREATMENT DISTANCES between 50 cm and 200 cm from the RADIATION SOURCE. The present standard describes measurements and test procedures to be performed by the MANUFACTURER at the design and construction stage of a medical ELECTRON ACCELERATOR but does not specify ACCEPTANCE TESTS to be performed after installation at the purchaser's site. The accompanying report, IEC 60977, however, does suggest that many of the test procedures are appropriate for ACCEPTANCE TESTS. The measurement conditions described in the present standard differ from those previously in use. This applies particularly to the PHANTOM position for measurements and the measurement of distances from the ISOCENTRE. These new conditions should be substituted for and not be added to previous methods. This standard specifies test procedures for the determination and disclosure of functional performance characteristics, knowledge of which is deemed necessary for proper application and use of a medical ELECTRON ACCELERATOR and which are to be declared in the ACCOMPANYING DOCUMENTS together with the greatest deviation or variation to be expected under specific conditions in NORMAL USE. A format for presentation of functional performance values is given in Annex A. It is recognized that inaccuracies in the test methods must be allowed for when assessing performance. However, it was not felt to be advisable to combine the errors into an overall performance tolerance but to keep them separate in the expectation that more accurate test methods will be evolved. It is not intended that this standard should in any way inhibit the future development of new designs of equipment which may have operating modes and parameters different from those described herein, provided that such equipment achieves equivalent levels of performance for the TREATMENT of PATIENTS. Except where otherwise stated this standard assumes that the medical ELECTRON ACCELERATORS have an ISOCENTRIC GANTRY. Where the equipment is non-isocentric, the description of performance and test methods may need to be suitably adapted.

Appareils électromédicaux - Accélérateurs médicaux d'électrons - Caractéristiques fonctionnelles de performance
S'applique aux accélérateurs médicaux d'électrons utilisés à des fins thérapeutiques, en médecine humaine. Cette norme s'applique aux accélérateurs médicaux d'électrons délivrant un faisceau de rayonnement soit rayonnement X soit rayonnement électronique avec des énergies nominales comprises dans l'intervalle de 1 MeV à 50 MeV avec un débit de dose absorbée maximum de 0,001 Gy s-1 à 1 Gy s-1 à 1 m de la source de rayonnement et à une distance normale de traitement entre 50 cm et 200 cm de la source de rayonnement. La présente norme décrit des mesures et des méthodes d'essai à réaliser par le fabricant au moment de la conception et de la construction d'un accélérateur médical d'électrons mais elle ne spécifie pas les essais de réception devant être effectués après l'installation sur le site de l'acheteur. Cependant, le rapport d'accompagnement CEI 60977 suggère que de nombreuses méthodes d'essai sont applicables aux essais de réception. Les conditions de mesure décrites dans la présente norme ne sont pas identiques à celles précédemment en usage. Cela s'applique en particulier à la position du fantôme pour les mesures et à la mesure des distances à partir de l'isocentre. Il convient que ces nouvelles conditions remplacent les précédentes et ne s'y ajoutent pas. Cette norme spécifie les méthodes d'essai pour la détermination et la déclaration des caractéristiques fonctionnelles dont la connaissance est nécessaire pour une application et une utilisation correctes d'un accélérateur médical d'électrons. Elles doivent être déclarées dans les documents d'accompagnement ainsi que les écarts ou variations maximum auxquels on peut s'attendre dans les conditions définies d'utilisation normale. Un modèle pour la présentation des valeurs des caractéristiques fonctionnelles est donné à l'Annexe A. Il est nécessaire de tenir compte de l'imprécision des méthodes de mesure dans la détermination des caractéristiques. Cependant, il n'a pas semblé souhaitable d'inclure les erreurs dans une tolérance globale, mais de les séparer, espérant que des méthodes de mesure plus précises soient mises au point. Il n'est pas dans le but de cette norme d'empêcher, de quelque façon que ce soit le développement futur d'équipements de conception nouvelle qui pourraient avoir des modes de fonctionnement et des paramètres différents de ceux décrits ci-après, à condition que de tels équipements conduisent à des caractéristiques fonctionnelles de niveau équivalent pour le traitement des patients. Sauf indication contraire, la présente norme s'applique aux accélérateurs médicaux d'électrons avec support isocentrique. Si l'équipement est non isocentrique, la description des caractéristiques et les méthodes d'essai peuvent nécessiter d'être convenablement adaptées. Cette deuxième édition annule et remplace la première édition publiée en 1989 dont elle constitue une révision technique. Cette deuxième édition comprend l'ajout de normes de performances et de méthodes d'essai en rapport avec les technologies nouvelles suivantes: - techniques de transmission du faisceau dynamiques, telles que la radiothérapie cinétique, la radiothérapie de conformation avec modulation d'intensité de dose (IMRT), la radiothérapie assistée par imagerie médicale (IGRT), et les faisceaux avec filtres en coin programmables (PWF); - radiotherapie stéréotaxique (SRT)/ radiochirurgie stéréotaxique (SRS); - utilisation de dispositifs d'imagerie électroniques. Il convient de lire cette norme ainsi que la CEI TR 60977 conjointement à la CEI 60601-2-1.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 60976 has been prepared by subcommittee 62C: Equipment for
radiotherapy, nuclear medicine and radiation dosimetry, of IEC technical committee 62:
Electrical equipment in medical practice.
This second edition cancels and replaces the first edition published in 1989. It constitutes a

INTRODUCTION
Standards containing safety requirements for medical ELECTRON ACCELERATORS have been
published by the IEC, details of which will be found in Clause 2.
The present standard specifies methods of testing and methods of disclosure of functional
performance of medical ELECTRON ACCELERATORS intended for RADIOTHERAPY. It permits a
direct comparison between the performance data of equipment of different MANUFACTURERS.
Since this standard does not contain safety requirements, it has not been numbered in the
IEC 60601 publication series. It describes aspects of functional performance of medical
ELECTRON ACCELERATORS and the way in which they should be presented. It also includes test
methods and conditions suitable for TYPE TESTS. These test methods are suggested test
methods and alternative methods may be equally appropriate, but the specified functional
performance characteristics of medical ELECTRON ACCELERATORS shall be related to these test
methods and conditions. Tests specified in this standard are not necessarily appropriate for
ensuring that any individual medical ELECTRON ACCELERATOR conforms to the declared
functional performance during the course of its working lifetime. Guidance on the values
which may be expected is given in the technical report, IEC 60977.
This International Standard was first published in 1989. With the rapidly increasing
