INTERNATIONAL ELECTROTECHNICAL VOCABULARY –
Part 651: Live working
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 60050-651 has been prepared by IEC technical committee 78: Live
working, under the responsibility of IEC technical committee 1: Terminology.
This second edition cancels and replaces the first edition published in 1999. It constitutes a
technical revision. It has the status of a horizontal standard in accordance with
IEC Guide 108.
This edition includes the following significant technical changes with respect to the previous
edition.
a) Changes have been made to the existing terminological entries.
b) New sections 21 to 26 replace the previous sections. They are more compact as they
contain only general terms.
c) Section 26 of this part of IEC 60050 provides additional terms of interest in the field of
electrical work. Whilst being not specifically associated to live working they do not appear
in any other IEV parts and were considered useful.
The text of this standard is based on the following documents:
FDIS Report on voting
1/2233/FDIS 1/2236/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.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
In this part of the IEV, the terms and definitions are provided in French and English; in
addition the terms are given in Arabic (ar), Chinese (zh), German (de), Spanish (es), Italian
(it), Japanese (ja), Polish (pl), Portuguese (pt), Russian (ru) and Swedish (sv).
A list of all parts of the IEC 60050 series, published under the general title International
Electrotechnical Vocabulary, can be found on the IEC website and is available at
www.electropedia.org.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under webstore.iec.ch in the data related to
the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
