(Main)Live working - Conductive clothing
Live working - Conductive clothing
IEC 60895:2020 is applicable to conductive clothing, worn during live working (especially bare-hand working) on AC and DC electrical installations, to provide electrical continuity between all parts of the clothing and a reduction of electric field inside the clothing.
This document is applicable to conductive clothing assembled from a conductive garment (jackets and trousers or coveralls forming a one-piece garment) and from conductive component parts (gloves, hoods or helmets, shoes or boots, overshoe socks and socks) in electrical systems with nominal voltage up to 1 000 kV AC and up to ±800 kV DC.
This document does not indicate values of protection from the effects of the electric arc, because any value indicated would not guarantee the necessary protection from the effects of electric arcs, or the operator would need to wear very heavy and rigid conductive clothing, which would not allow the execution of the work in safety.
The products designed and manufactured according to this document contribute to the safety of the users provided they are used by persons trained for the work, in accordance with the live working methods and the instructions for use.
This third edition cancels and replaces the second edition, published in 2002. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) increase of the use up to 1 000 kV AC and ±800 kV DC;
b) introduction of two classes of conductive clothing with different electrical requirements;
c) revision of the electrical requirements of conductive clothing;
d) definition of specific resistance values for each component part of the conductive clothing;
e) introduction of conductive helmet and conductive scarf as component parts of conductive clothing;
f) introduction of mechanical requirements and new tests for fabrics;
g) update of the cleaning test procedures;
h) revision of the efficiency test of the conductive clothing to improve the feasibility and repeatability;
i) preparation of the elements of classification of defects, and general application of IEC 61318:2007;
j) the normative Annex B for the classification of tests has been replaced by normative Annex C for the general type tests procedure, the normative Annex D for the classification of defects and the informative Annex E providing the justification for the classification of defects;
k) the normative Annex C on sampling procedure has been deleted (not applicable according to IEC 61318:2007);
l) modification of the recommended frequency of the periodic tests.
Arbeiten unter Spannung - Leitfähige Kleidung
Travaux sous tension – Vêtements conducteurs
IEC 60895: 2020 est applicable aux vêtements conducteurs portés lors des travaux sous tension (en particulier lors du travail au potentiel) sur des installations électriques à courant alternatif et à courant continu pour assurer une continuité électrique entre les différentes parties du vêtement et une réduction du champ électrique à l'intérieur du vêtement.
Le présent document est applicable aux vêtements conducteurs constitués d'un article d’habillement conducteur (vestes et pantalons ou article d’habillement d'une seule pièce) ou de parties composantes conductrices (gants, cagoules ou casques, chaussures ou bottes, couvre-chaussures et chaussettes) dans des systèmes électriques avec une tension nominale allant jusqu'à 1 000 kV en courant alternatif et jusqu'à ±800 kV en courant continu.
Le présent document n'indique pas les valeurs de protection contre les effets des arcs électriques, car les valeurs indiquées ne garantissent pas la protection nécessaire contre les effets des arcs électriques, ou l'opérateur serait contraint de porter des vêtements conducteurs très lourds et rigides, ce qui empêche l'exécution des travaux en toute sécurité.
Les produits conçus et fabriqués conformément au présent document contribuent à la sécurité des utilisateurs, à condition qu'ils soient utilisés par des personnes averties dans le respect des méthodes applicables au travail sous tension et des instructions d'emploi.
Cette troisième édition annule et remplace la deuxième édition, parue en 2002. Cette édition constitue une révision technique.

a) augmentation de l'utilisation jusqu'à 1 000 kV en courant alternatif et ±800 kV en courant continu;
b) introduction de deux classes de vêtements conducteurs avec différentes exigences électriques;
c) révision des exigences électriques du vêtement conducteur;
d) définition de valeurs de résistance spécifiques pour chaque partie composante du vêtement conducteur;
e) introduction du casque conducteur et de l'écharpe conductrice en tant que parties composantes du vêtement conducteur;
f) introduction d'exigences mécaniques et de nouveaux essais pour les tissus;
g) mise à jour des procédures d'essai de nettoyage;
h) révision de l'essai d'efficacité du vêtement conducteur pour améliorer la faisabilité et la répétabilité;
i) préparation des éléments de classification des défauts et application générale de l'IEC 61318:2007;

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.

INTRODUCTION
This document provides specifications for protective conductive clothing currently being used
without incident in live work by qualified electrical workers throughout the world. The adequacy
of this clothing is established by its screening efficiency and the electrical resistance of material
and component parts of the conductive clothing. Based on resistance measurements carried
out by manufacturers and utilities of used clothing being successfully worn in the field,
differences of up to 1 000 fold have been reported.
The whole set-up and preparation work in very high voltage is made to limit the power of electric
arcs during work activities.
When, in the preparation phase of the work, the risk assessment leads to a high probability that
there may be electric arcs, due to the short distances or unsuitable equipment insulation, the
work is not done.
This approach is dictated by the fact that the electric arcs produced by high-voltage installations
have very significant thermal and electrical effects, which are hardly attenuated by protective
clothing worn by operators.
If protection against electric arc value is required by agreements between customer and
manufacturer, it is possible to perform tests on the fabric and/or on the garment complete with
accessories using the reference standards already published on this topic by IEC TC 78.
This document has been prepared according to the requirements of IEC 61477, where
applicable.
The bibliography provides a list of papers of international level that were used during the
development of this edition of IEC 60895.
The product covered by this document 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 duration, and occur at the global, regional or local level.
This document 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.

LIVE WORKING – CONDUCTIVE CLOTHING
1 Scope
This document is applicable to conductive clothing, worn during live working (especially bare-
hand working) on AC and DC electrical installations, to provide electrical continuity between all
parts of the clothing and a reduction of electric field inside the clothing.
This document is applicable to conductive clothing assembled from a conductive garment
(jackets and trousers or coveralls forming a one-piece garment) and from conductive component
parts (gloves, hoods or helmets, shoes or boots, overshoe socks and socks) in electrical
systems with nominal voltage up to 1 000 kV AC and up to ±800 kV DC.
This document does not indicate values of protection from the effects of the electric arc,
because any value indicated would not guarantee the necessary protection from the effects of
electric arcs, or the operator would need to wear very heavy and rigid conductive clothing, which
would not allow the execution of the work in safety.
The products designed and manufactured according to this document contribute to the safety
of the users provided they are used by persons trained for the work, in accordance with the live
working methods and the instructions for use.

4 Requirements
4.1 General
The following requirements have been prepared in order that the products covered by this
document are designed and manufactured to contribute to the safety of the users, provided they
are used by persons skilled for live working, in accordance with safety method of work and the
instructions for use.
4.2 Requirements for conductive clothing
4.2.1 Design
The conductive clothing shall constitute an electrically continuous assembly for the worker.
The conductive clothing can be made of a single conductive material layer, or it can be made
of a multilayer. In case of a multilayer, the outer layer material of the conductive clothing may
be conductive or non-conductive, but at least one layer shall be conductive.
If press studs, zip fasteners, hooks and eyes or any other method of fastening are used in the
assembly of the complete conductive clothing, the electrical conductivity of the clothing should
not be impaired.
The bonding lead shall be capable of withstanding the anticipated electrical and mechanical
stresses. The design of the equipotential bonding lead should be such that it does not interfere
with the emergency procedures, for example, in case of a fall.
If the garment is made up of more than one piece (for example, separate jacket or trousers),
the method of attachment (bonding) of the individual pieces shall be electrically continuous.
The overlap of the individual component parts shall be such as to ensure that the body of the
worker is totally covered.
4.2.2 Classification
The conductive clothing covered by this document shall be designated as follows:
– by maximum voltage as class 1 (800 kV AC / ±600 kV DC) or class 2 (1000 kV AC /
±800 kV DC);
– by the maximum nominal AC and DC voltage at which the conductive clothing can be used
(according to the test conditions for screening efficiency).
Guidance for the selection of maximum voltage class (AC and DC) is given in Annex A.
NOTE The maximum voltage class 1 corresponds in general criteria to the conductive clothing of IEC 60895:2002
(up to 800 kV AC and ±600 kV DC).
4.2.3 Integrity of the conductive clothing
The conductive clothing shall be assembled with all its component parts. All the connection
systems according to the design shall work properly. All the component parts shall not be
damaged or deteriorated in normal use, and shall be controlled as specified in 5.5.2. This
requirement applies to both maximum voltage classes.

4.2.4 Equipotential bonding
All the component parts of the complete conductive clothing shall be designed to be electrically
bonded, and shall be controlled as specified in 5.5.3. This requirement shall respect the value
for each maximum voltage class shown in Table 4.
4.2.5 Screening efficiency
The conductive clothing shall attenuate the electric field. The attenuation of the conductive
clothing is determined by screening efficiency. This requirement shall be controlled as specified
in 5.5.4 and shall respect Table 6 or Table 7.
