Medical electrical equipment - Medical light ion beam equipment - Performance characteristics (IEC 62667:2017)

This document applies to LIGHT ION BEAM ME EQUIPMENT when used, for therapy purposes, in
human medical practice.
This document applies to LIGHT ION BEAM ME EQUIPMENT which delivers LIGHT ION BEAMS with an
ENERGY PER NUCLEON in the range 10 MeV/n to 500 MeV/n.
This document describes measurements and test procedures to be performed by the
MANUFACTURER of LIGHT ION BEAM ME EQUIPMENT but does not specify ACCEPTANCE TESTS.
This document specifies test procedures for the determination and disclosure of performance
characteristics, knowledge of which is necessary for proper selection, application, and use of
LIGHT ION BEAM ME EQUIPMENT and which are to be declared in the ACCOMPANYING
DOCUMENTATION together with the greatest deviation or variation to be expected under specific
conditions in NORMAL USE. A format for presentation of performance values is given in
Annex A.
It is recognized that inaccuracies in the test methods can occur when assessing performance.
However, it was felt preferable not to combine the errors into an overall performance
tolerance but rather to keep them separate in the expectation that more accurate test methods
will evolve.
It is not intended that this document 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 or better levels of performance for
the TREATMENT of PATIENTS.
This document applies to both ISOCENTRIC and non-ISOCENTRIC GANTRIES but many of the tests
assume that the LIGHT ION BEAM ME EQUIPMENT has an ISOCENTRIC GANTRY. Where the
equipment is non-ISOCENTRIC, the description of performance and test methods may be
suitably adapted.

L'IEC 62667:2017 s'applique aux appareils EM par faisceau d'ions légers utilisés dans la pratique médicale humaine à des fins de thérapie. Le présent document s'applique aux appareils EM par faisceau d'ions légers qui produisent des faisceau d'ions légers avec une énergie par nucléon dans la plage comprise entre 10 MeV/n et 500 MeV/n. Le présent document spécifie les mesurages et les procédures d'essai que le fabricant des appareils EM par faisceau d'ions légers doit réaliser. Elle ne définit pas en revanche d'essais d'acceptation. Le présent document définit des procédures d'essai pour la détermination et la communication des caractéristiques de performances, dont la connaissance est nécessaire pour le choix, l'application et l'utilisation corrects des appareils EM par faisceau d'ions légers. Ces procédures doivent être déclarées dans les documentations d'accompagnement, ainsi que l'écart ou la variation maximal(e) à prévoir dans des conditions d'utilisation normale spécifiques. Un format de présentation des valeurs de performances est fourni à l'Annexe A.

Medicinska električna oprema - Medicinska oprema s šibkim ionskim žarkom - Tehnične lastnosti (IEC 62667:2017)

Ta dokument velja za ELEKTROMEDICINSKO OPREMO S ŠIBKIM IONSKIM ŽARKOM, če se oprema uporablja za zdravljenje ljudi.
Ta dokument velja za ELEKTROMEDICINSKO OPREMO S ŠIBKIM IONSKIM ŽARKOM, ki sprošča ŠIBKE IONSKE ŽARKE z ENERGIJO NA NUKLEON v razponu od 10 MeV/n do 500 MeV/n.
Ta dokument opisuje meritve in preskusne postopke, ki jih mora opraviti PROIZVAJALEC ELEKTROMEDICINSKE OPREME S ŠIBKIM IONSKIM ŽARKOM, vendar ne določa PRESKUSOV SPREJEMLJIVOSTI.
Ta dokument določa preskusne postopke za ugotavljanje in navajanje delovnih karakteristik, ki jih je treba poznati za pravilno izbiro, apliciranje in uporabo ELEKTROMEDICINSKE OPREME S ŠIBKIM IONSKIM ŽARKOM in ki jih je treba navesti v PRILOŽENI DOKUMENTACIJI skupaj z največjimi odstopanji ali spremembami, ki jih je mogoče pričakovati pod določenimi pogoji pri OBIČAJNI UPORABI. Format za predstavitev vrednosti lastnosti je podan v dodatku A.
Ugotovljeno je, da lahko pri ocenjevanju delovanja pride do netočnosti v preskusni metodi. Vendar se je zdelo bolje, da napake niso združene v skupna odstopanja v delovanju, ampak ostanejo ločene, saj se pričakuje razvoj bolj točnih preskusnih metod.
Namen tega dokumenta ni, da bi na kakršen koli način oviral prihodnji razvoj nove opreme, ki bo lahko imela drugačne načine delovanja in parametre, kot so opisani v tem dokumentu, pod pogojem da takšna oprema dosega enakovredno ali boljšo raven učinkovitosti za ZDRAVLJENJE BOLNIKOV.
Ta dokument velja tako za IZOCENTRIČNE kot za ne-IZOCENTRIČNE NOSILCE, vendar številni testi predpostavljajo, da ima ELEKTROMEDICINSKA OPREMA S ŠIBKIM IONSKIM ŽARKOM IZOCENTRIČNI NOSILEC. Če oprema ni IZOCENTRIČNA, je lahko opis delovanja in preskusnih metod ustrezno prilagojen.

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 62667 has been prepared by subcommittee 62C: Equipment for

radiotherapy, nuclear medicine and radiation dosimetry, of IEC Technical Committee 62:

Electrical equipment in medical practice.
The text of this standard is based on the following documents:
