Live working - Insulating sticks and attachable devices - Part 1: Insulating sticks
IEC 60832-1:2010 gives the essential requirements for insulating sticks for live working for use on a.c. electrical installations. The products designed and manufactured according to this standard contribute to the safety of the users provided they are used by skilled persons, in accordance with safe methods of work and the instructions for use. IEC 60832-1:2010 and IEC 60832-2:2010 cancel and replace the first edition of IEC 60832 published in 1988. The two parts have been created to clearly separate the requirements and testing of insulating sticks from those of attachable devices. Compared to IEC 60832, the major changes included in IEC 60832-1 are:
- integration of a cold impact test on the end fitting;
- creation of an electrical category of end fittings;
- integration of a test of the dielectric strength of internal insulation;
- modification of the dye penetration test (disappearance of fuchsine);
- application of conformity assessment for products having completed the production phase, according to IEC 61318:2007 (Edition 3), focusing on the classification of defects and the introduction of alternative testing in case of production follow-up.
Travaux sous tension - Perches isolantes et outils adaptables - Partie 1: Perches isolantes
La CEI 60832-1:2010 définit les exigences essentielles, pour une utilisation sur des installations électriques à tension alternative, des perches isolantes pour travaux sous tension. Les produits conçus et fabriqués en conformité avec la présente norme contribuent à la sécurité des utilisateurs, pourvu qu'ils soient utilisés par des personnes qualifiées, conformément à des méthodes de travail en toute sécurité et aux instructions d'emploi. La CEI 60832-1:2010 et la CEI 60832-2:2010 annulent et remplacent la première édition de la CEI 60832 publiée en 1988. Les deux parties ont été créées pour séparer clairement les exigences et les essais des perches isolantes de ceux des outils adaptables. Par rapport à la CEI 60832, les principales modifications introduites dans la CEI 60832-1 sont:
- l'intégration d'un essai de choc à froid sur l'embout de perche;
- la création d'une catégorie électrique des embouts de perche;
- l'intégration d'un essai de tenue diélectrique de l'isolation interne;
- la modification de l'essai de pénétration de colorant (disparition de la fuchsine);
- l'évaluation de la conformité des produits issus de la production selon les dispositions définies dans la CEI 61318:2007 (édition 3) en s'appliquant à classifier les défauts et à introduire des essais alternatifs pour le suivi de la production.

LIVE WORKING – INSULATING STICKS
AND ATTACHABLE DEVICES –
Part 1: Insulating sticks
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 60832-1 has been prepared by IEC technical committee 78: Live
working.The first edition of IEC 60832-1 and that of IEC 60832-2 cancel and replace the first edition of
IEC 60832 published in 1988. The two parts have been created to clearly separate the
requirements and testing of insulating sticks from those of attachable devices.Compared to IEC 60832, the major changes included in IEC 60832-1 are:
• integration of a cold impact test on the end fitting;
• creation of an electrical category of end fittings;
• integration of a test of the dielectric strength of internal insulation;
• modification of the dye penetration test (disappearance of fuchsine);

INTRODUCTION
The purpose of this standard is to provide essential requirements. Each user may supplement
it with their own requirements. For example, the user may add requirements regarding the use
of insulating sticks on d.c. electrical installations or the mechanical performance or
compatibility and interchangeability with tools already in service. In such cases, caution
should be taken to maintain or improve the performance of the products.This publication has been prepared in accordance with the requirements of IEC 61477.
The products designed and manufactured according to this standard contribute to the safety
of the users provided they are used by skilled persons, in accordance with safe methods of
work and the instructions for use.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.Except for a disposal statement in the instructions for use, and special considerations for the
selection of a dye (see 5.6), 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.---------------------- Page: 8 ----------------------
