Medical electrical equipment - Part 2-62: Particular requirements for the basic safety and essential performance of high intensity therapeutic ultrasound (HITU) equipment

IEC 60601-2-62:2013 applies to the basic safety and essential performance of HIGH INTENSITY THERAPEUTIC ULTRASOUND EQUIPMENT. This International Standard adds or replaces clauses listed in the IEC 60601-1 that are specific for HIGH INTENSITY THERAPEUTIC ULTRASOUND EQUIPMENT. If a clause or subclause is specifically intended to be applicable to such equipment only, or to related 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 individual equipment and to systems, as relevant. Hazards inherent in the intended physiological function of the equipment or systems within the scope of this standard are not covered by specific requirements in this standard except in 7.2.13 and 8.4.1 of the general standard. This standard can also be applied to - therapeutic equipment for thrombolysis through exposure to high-intensity therapeutic ultrasound; - therapeutic equipment for the treatment of occluding feeding vessels through exposure to high-intensity focused ultrasound; - and equipment intended to be used for relieving cancer pain due to bone metastases. This particular standard does not apply to - Ultrasound Equipment intended to be used for physiotherapy (use IEC 60601-2-5 and IEC 61689); - Ultrasound Equipment intended to be used for lithotripsy (use IEC 60601-2-36); - Ultrasound Equipment intended to be used for dedicated hyperthermia devices; and - Ultrasound Equipment intended to be used for phacoemulsification.

Appareils électromédicaux - Partie 2-62: Exigences particulières pour la sécurité de base et les performances essentielles des appareils ultrasonores thérapeutiques de haute intensité (HITU)

La CEI 60601-2-62:2013 s'applique à la sécurité de base et aux performances essentielles des APPAREILS ULTRASONORES THÉRAPEUTIQUES DE HAUTE INTENSITÉ. La présente Norme internationale complète ou remplace les articles énumérés dans la CEI 60601-1 qui sont spécifiques aux APPAREILS ULTRASONORES THÉRAPEUTIQUES DE HAUTE INTENSITÉ. Si un article ou un paragraphe est spécifiquement destiné à s'appliquer uniquement aux appareils individuels, ou uniquement aux systèmes, le titre et le contenu dudit article ou paragraphe devra alors le préciser. Dans le cas contraire, l'article ou le paragraphe s'applique aux appareils individuels et aux systèmes, selon le cas. Les dangers inhérents à la fonction physiologique prévue des appareils individuels ou des systèmes dans le cadre de la présente norme ne sont pas couverts par les exigences spécifiques de la présente norme, excepté en 7.2.13 et en 8.4.1 de la norme générale. La présente norme peut également être appliquée - à des appareils thérapeutiques pour thrombolyse par exposition à des ultrasons thérapeutiques de haute intensité; - à des appareils thérapeutiques pour le traitement de l'occlusion de vaisseaux nourriciers par exposition à des ultrasons focalisés de haute Intensité; - et aux appareils destinés à être utilisés pour atténuer la douleur liée au cancer et due aux métastases osseuses. La présente norme particulière ne s'applique pas - aux appareils à ultrasons destinés à être utilisés pour la physiothérapie (utilisation: CEI 60601-2-5 et CEI 61689); - aux appareils à ultrasons destinés à être utilisés pour la lithotritie (utilisation: CEI 60601-2-36); - aux appareils à ultrasons destinés à être utilisés pour des dispositifs dédiés à l'hyperthermie; - et aux appareils à ultrasons destinés à être utilisés pour la phacoémulsification.

Medicinska električna oprema - 2-62. del: Posebne zahteve za osnovno varnost in bistvene lastnosti visokointenzivnih terapevtskih ultrazvočnih (HITU) naprav

Ta mednarodni standard se uporablja za OSNOVNO VARNOST in BISTVENE LASTNOSTI VISOKOINTENZIVNIH
TERAPEVTSKIH ULTRAZVOČNIH NAPRAV, kot so opredeljene v točki 201.3.218 (v nadaljevanju ELEKTROMEDICINSKA OPREMA).
Ta mednarodni standard dodaja ali zamenja klavzule, navedene v standardu IEC 60601-1, ki se nanašajo na VISOKOINTENZIVNE TERAPEVTSKE ULTRAZVOČNE NAPRAVE.
Če je točka ali podtočka namenjena samo obravnavi ELEKTROMEDICINSKE OPREME ali ELEKTROMEDICINSKIH SISTEMOV, bo to zapisano v naslovu in vsebini točke ali podtočke. Če ni zapisano, točka ali podtočka obravnava ELEKTROMEDICINSKO OPREMO in ELEKTROMEDICINSKE SISTEME. Posebne zahteve tega standarda ne vključujejo temeljnih TVEGANJ pri nameravani fiziološki funkciji ELEKTROMEDICINSKE OPREME in SISTEMOV, ki spadajo na področje tega standarda, razen v poglavjih 7.2.13 in 8.4.1 splošnega standarda.
OPOMBA 1: Glej tudi točko 4.2 splošnega standarda.
OPOMBA 2: Ker se na področju HITU pričakuje, da je akustično valovanje močno popačeno zaradi nelinearnih učinkov širjenja zvoka, je potrebno ultrazvočne meritve opraviti v navidezno linearnih pogojih in jih nato ekstrapolirati s postopki, podanimi v standardu IEC/TS 62556. Glejte tudi IEC/TS 61949
Ta standard je mogoče uporabiti tudi za:
– terapevtsko opremo za trombolizo prek obsevanja z visokointenzivnim terapevtskim ultrazvokom;
– terapevtsko opremo za zdravljenje zamašenih dovodnic z obsevanjem z visokointenzivnim osredotočenim ultrazvokom;
– opremo, namenjeno lajšanju bolečin raka, ki so posledica kostnih metastaz.
Ta standard se ne uporablja za:
• ULTRAZVOČNO OPREMO, namenjeno fizioterapiji (uporabite standarda IEC 60601-2-5 [1]2) in IEC 61689);
• ULTRAZVOČNO OPREMO, namenjeno litotripsiji (uporabite standard IEC 60601-2-36 [2]);
• ULTRAZVOČNO OPREMO, namenjeno uporabi za namenske hipertermične naprave;
• ULTRAZVOČNO OPREMO, namenjeno fakoemulzifikaciji.

Part 2-62: Particular requirements for the basic safety and essential
performance of high intensity therapeutic ultrasound (HITU) equipment
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 OPERATOR.

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 60601-2-62 has been prepared by IEC subcommittee 62D:

[Therapy equipment] Electromedical equipment, of IEC technical committee 62: Electrical

equipment in medical practice. It has been prepared in close co-operation with TC 87

(Ultrasonics).

Directives, Part 2. For the purposes of this standard, the auxiliary verb:

– “shall” means that compliance with a requirement or a test is mandatory for compliance

with this standard;

– “should” means that compliance with a requirement or a test is recommended but is not

mandatory for compliance with this standard;

– “may” is used to describe a permissible way to achieve compliance with a requirement or

test.

An asterisk (*) as the first character of a title or at the beginning of a paragraph or table title

indicates that there is guidance or rationale related to that item in Annex AA.

A list of all parts of the IEC 60601 series, published under the general title Medical electrical

equipment, can be found on the IEC website.

The committee has decided that the contents of this publication will remain unchanged until

the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data

related to the specific publication. At this date, the publication will be

INTRODUCTION

In this particular standard, safety requirements additional to those in the general standard are

specified for HIGH INTENSITY THERAPEUTIC ULTRASOUND (HITU) EQUIPMENT.
This particular standard takes into account IEC 62555 and IEC/TS 62556.
The requirements are followed by specifications for the relevant tests.

A rationale for the more important requirements, where appropriate, is given in Annex AA. It is

considered that knowledge of the reasons for these requirements will not only facilitate the

proper application of the particular standard but will, in due course, expedite any revision

necessitated by changes in clinical practice or as a result of developments in technology.

However this annex does not form part of the requirements of this standard.

This International Standard adds or replaces clauses listed in the IEC 60601-1 that are

specific for HIGH INTENSITY THERAPEUTIC ULTRASOUND EQUIPMENT.

If a clause or subclause is specifically intended to be applicable to ME 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 ME EQUIPMENT and to ME SYSTEMS, as relevant.

HAZARDS inherent in the intended physiological function of ME EQUIPMENT or ME SYSTEMS

within the scope of this standard are not covered by specific requirements in this standard

except in 7.2.13 and 8.4.1 of the general standard.
NOTE 1 See also 4.2 of the general standard.

NOTE 2 As, in HITU fields, the acoustic waveform is expected to be extremely distorted due to non-linear

propagation effects, the ultrasonic measurements are to be made under quasi linear conditions and then

extrapolated following procedures given in IEC/TS 62556. See also IEC/TS 61949
This standard can also be applied to:

– therapeutic equipment for thrombolysis through exposure to high-intensity therapeutic

ultrasound;

– therapeutic equipment for the treatment of occluding feeding vessels through exposure to

high-intensity focused ultrasound;

– equipment intended to be used for relieving cancer pain due to bone metastases.

This particular standard does not apply to:

• ULTRASOUND EQUIPMENT intended to be used for physiotherapy (use: IEC 60601-2-5 [1]

and IEC 61689);

• ULTRASOUND EQUIPMENT intended to be used for lithotripsy (use: IEC 60601-2-36 [2]);

• ULTRASOUND EQUIPMENT intended to be used for dedicated hyperthermia devices;
• ULTRASOUND EQUIPMENT intended to be used for phacoemulsification.

201.1.2 Object
Replacement:

The object of this particular standard is to establish particular BASIC SAFETY and ESSENTIAL

PERFORMANCE requirements for HIGH INTENSITY THERAPEUTIC ULTRASOUND (HITU) EQUIPMENT [as

defined in 201.3.218.]
201.1.3 Collateral standards
Addition:

This particular standard refers to those applicable collateral standards that are listed in

Clause 2 of the general standard and Clause 201.2 of this particular standard.

IEC 60601-1-2:2007 applies as modified in Clause 202. All other published collateral

standards in the IEC 60601-1 series apply as published.
201.1.4 Particular standards
Replacement:

In the IEC 60601 series, particular standards may modify, replace or delete requirements

contained in the general standard and collateral standards as appropriate for the particular

ME EQUIPMENT under consideration, and may add other BASIC SAFETY and ESSENTIAL
PERFORMANCE requirements.
A requirement of a particular standard takes priority over the general standard.

For brevity, IEC 60601-1 is referred to in this particular standard as the general standard.

Collateral standards are referred to by their document number.

The numbering of clauses and subclauses of this particular standard corresponds to that of

the general standard with the prefix “201” (e.g. 201.1 in this particular standard addresses the

content of Clause 1 of the general standard) or applicable collateral standard with the prefix

“20x” where x is the final digit(s) of the collateral standard document number (e.g. 202.4 in

this particular standard addresses the content of Clause 4 of the IEC 60601-1-2 collateral

standard, 203.4 in this particular standard addresses the content of Clause 4 of the

IEC 60601-1-3 collateral standard, etc.). The changes to the text of the general standard are

specified by the use of the following words:

"Replacement" means that the clause or subclause of the general standard or applicable

collateral standard is replaced completely by the text of this particular standard.

"Addition" means that the text of this particular standard is additional to the requirements of

the general standard or applicable collateral standard.

"Amendment" means that the clause or subclause of the general standard or applicable

collateral standard is amended as indicated by the text of this particular
