MEDICAL ELECTRICAL EQUIPMENT –
GLOSSARY OF DEFINED TERMS
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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC 60788, which is a technical report, has been prepared by IEC TC 62: Electrical EQUIPMENT
in medical practice.
This second edition cancels and replaces the first edition of IEC 60788 published in 1984.
This second edition constitutes a technical revision.
The text of this technical report is based on the following documents:
Enquiry draft Report on voting
62/137/DTR 62/140/RVC
Full information on the voting for the approval of this technical report can be found in the
report on voting indicated in the above table.
This publication does not follow the rules for structuring International Standards as given in
Part 2 of the ISO/IEC Directives.

TR 60788 ©IEC:2004(E) – 3 –
The committee has decided that the contents of this publication will remain unchanged until
2005. At this date, the publication will be
• reconfirmed;
•withdrawn;
• replaced by a revised edition, or
• amended.

INTRODUCTION
Purpose
– To provide an actual mirror of defined terms for all steps in the development of IEC
standards under the scope of “MEDICAL ELECTRICAL EQUIPMENT”, IEC TC 62.
– To give guidance for harmonisation of the defined terms used in the IEC standards on
“MEDICAL ELECTRICAL EQUIPMENT”.
Contents
– All DEFINED TERMS used in the General, Particular and Collateral Standards, recorded in
the project files of the IEC for TC 62, SC 62A, 62B, 62C and 62D are mirrored.
– Recommendations to avoid existing redundancy are added as red text in the column
“Definitions” in the table.
Maintenance
– An annual maintenance cycle for this TR is introduced. Closing date for the editorial input
is the middle of December of a year.
– The annual editorial maintenance is done by the Secretaries of the IEC technical
committee 62 and its subcommittees 62A, 62B, 62C and 62D.
– The compilation (addition of new terms and deletion of obsolete terms) is done by the
Secretary of IEC TC 62.
Targets
– Represent the state-of-the-art in the definitions
– Harmonize the language of the IEC publications
– Ease translations of the IEC publications
– Enable self-control by the experts working in projects for MEDICAL ELECTRICAL EQUIPMENT.
Coded reference of the DEFINED TERMS
– In all cases – as appropriate – the reference codes “IEV xxx-xx-xx” of the International
Electronic Vocabulary (IEV) are added in the “Reference” column of the table.
–For DEFINED TERMS used in RADIOLOGY the reference codes “rm-xx-xx” remain unchanged
as initiated by IEC 60788 Ed.1.
– For main fields other than RADIOLOGY, the coded references will be generated in future
annual editions.
Replacement
This technical report replaces IEC 60788 Ed.1, Medical radiology – Terminology.
