Part 2-5: Particular requirements for the safety of
ultrasonic physiotherapy 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 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 60601-2-5 has been prepared by sub-committee 62D: Electro-
medical equipment, of IEC technical committee 62: Electrical equipment in medical practice.
This second edition of IEC 60601-2-5 cancels and replaces the first edition published in 1984
of which it constitutes a technical revision.
This bilingual version (2005-11) replaces the English version.
The text of this standard is based on the following documents:
FDIS Report on voting
62D/361/FDIS 62D/366/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.

The French version of this standard has not been voted upon.
In this Particular Standard the following print types are used:
– requirements, compliance with which can be tested, and definitions: roman type;
– notes, explanations, advice, introductions, general statements, exceptions and references: smaller type;
– test specifications, headings of subclauses and headings of items: italic type;
– TERMS DEFINED IN CLAUSE 2 OF THE GENERAL STANDARD OR THIS PARTICULAR STANDARD: SMALL
CAPITALS.
The committee has decided that the contents of this publication will remain unchanged until the
maintenance result 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
• reconfirmed;

INTRODUCTION
This Particular Standard specifies requirements and tests for the safety of ULTRASONIC
PHYSIOTHERAPY EQUIPMENT. It amends and supplements IEC 60601-1 (second edition, 1988)
including Amendments 1 and 2, hereinafter referred to as the General Standard. This Particular
Standard takes into account IEC 60601-1-2 and IEC 61689.
A first edition of this Particular Standard was published in 1984, based on the first edition
(1977) of IEC 60601-1 and making reference to IEC 60150. The aim of this second edition is to
bring this Particular Standard up to date with reference to the publications and documents
mentioned above. The title has been changed to better reflect its scope based on
developments in the therapeutic application of ultrasound and in line with changes in the above
IEC standards.
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 a 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.
The clauses and subclauses which have corresponding rationale statements are marked with
an asterisk * before their number.
