HAND TOOLS FOR USE UP

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 60900 has been prepared by IEC technical committee 78: Live
working.
This third edition cancels and replaces the second edition, published in 2004. This edition
constitutes a technical revision.
It includes the following significant technical changes with regard to the previous edition:
• general review of the requirements and test provisions;
• preparation of the elements of evaluation of defects, and general application of
IEC 61318:2007 (Ed.3);
• deletion of Annexes D and E, not applicable according to IEC 61318 Ed.3;
• introduction of a new normative Annex D on chronology of type tests;
• introduction of a new normative Annex F on classification of defects.

INTRODUCTION
This International Standard has been prepared in accordance with the requirements of
IEC 61477 where applicable.
The product covered by this standard may have an impact on the environment during some or
all stages of its life cycle. These impacts can range from slight to significant, be of short-term
or long-term, and occur at the global, regional or local level.
This standard does not include requirements and test provisions for the manufacturers of the
product, or recommendations to the users of the product for environmental improvement.
However, all parties intervening in its design, manufacture, packaging, distribution, use,
maintenance, repair, reuse, recovery and disposal are invited to take account of
environmental considerations.
