Live working - Gloves of insulating material
Is applicable to: - insulating gloves and mitts which should normally be used in conjunction with leather protector gloves worn over the insulating gloves to provide mechanical protection; - insulating gloves and mitts usable without over-gloves for mechanical protection. Unless otherwise stated, the use of the term glove includes both gloves and mitts. The use of the term insulating gloves designates gloves providing electrical protection only. The use of the term composite gloves designates gloves providing electrical and mechanical protection.

Travaux sous tension - Gants en matériau isolant
Applicable: - aux gants et moufles isolants, qu'il convient normalement d'utiliser avec un surgant de cuir qui donne la protection mécanique; - aux gants et moufles isolants utilisés sans surgants protecteurs. Sauf indication contraire, l'utilisation du seul terme "gant" comprend gant et moufle. Le terme "gants isolants" désigne les gants qui fournissent uniquement une protection électrique. Le terme "gants composites" désigne les gants fournissant une protection mécanique et électrique.

This European Standard was approved by CENELEC on 2003-07-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Czech Republic,
Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Lithuania, Luxembourg, Malta,

Foreword
The text of document 78/462A/FDIS, future edition 2 of IEC 60903, prepared by IEC TC 78, Live
working, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as
EN 60903 on 2003-07-01.
A draft amendment, prepared by the Technical Committee CENELEC TC 78, Equipment and tools for
live working, was submitted to the formal vote and was approved by CENELEC for inclusion into
EN 60903 on 2003-07-01.
This European Standard
– supersedes EN 60903:1992 + A11:1997, covering insulating gloves (and mitts) which would
normally be used in conjunction with leather protector gloves worn over the insulating gloves (and
mitts) to provide mechanical protection,
– supersedes EN 50237:1997, covering gloves (and mitts) which combine in one unique glove the
insulating properties of elastomer gloves and the mechanical properties of leather gloves. The
result of the combination is defined as a composite glove;
– includes requirements and testing for a “long composite glove" which extends protection to most of
the upper arm.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2004-07-01
national standard or by endorsement
– latest date by which the national standards conflicting
(dow) 2006-07-01
with the EN have to be withdrawn
This European Standard was prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association and supports the essential requirements of
Directive 89/686/EEC.
NOTE Subclauses which are additional to those in IEC 60903 are prefixed "Z".
Annexes designated "normative" are part of the body of the standard.
Annexes designated "informative" are given for information only.
In this standard, annexes A, B, C and ZA are normative and annexes D, E, F, G, H and I are
informative.
Annex ZA has been added by CENELEC.

LIVE WORKING–
GLOVES OF INSULATING MATERIAL
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60903 has been prepared by IEC technical committee 78: Live
working.
This second edition:
– cancels and replaces the first edition of IEC 60903, published in 1988, covering insulating
gloves (and mitts) which would normally be used in conjunction with leather protector
gloves worn over the insulating gloves (and mitts) to provide mechanical protection;
– includes and cancels IEC 61942, first edition, published in 1997, covering gloves (and
mitts) which combine in one unique glove the insulating properties of elastomer gloves
and the mechanical properties of leather gloves. The result of the combination is defined
as a composite glove;
– includes requirements and testing for a “long composite glove” which extends protection to
most of the upper arm.
The text of this standard is based on the following documents:
FDIS Report on voting
78/462A/FDIS 78/479/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.

At this date, the publication will be
• reconfirmed;
• withdrawn;

INTRODUCTION
In this document, the clauses on requirements and testing are reorganized in order to bring
together the common requirements and tests, then to lay down separately those which are
specific to insulating gloves for electrical protection normally worn under leather protector
gloves as opposed to those specific to insulating gloves for combined electrical and
mechanical protection. This arrangement meets the basic necessity that a same quality level
of electrical insulation is achieved for all types of insulating gloves.
This document has been prepared according to the requirements of IEC 61477 where
applicable.
