Live working - Insulating hoses with fittings for use with hydraulic tools and equipment
Is applicable to mobile insulating hoses with fittings used with hydraulic tools and equipment for live working at nominal voltages exceeding 1 kV r.m.s. at power frequency. Insulating hoses with fittings are used to provide a connection between the hydraulic tool and the pump which are at different potentials. They are not considered as a fixed component of a live working device (e.g. aerial device). They can be connected and disconnected under negligible pressure. They can be directly handled by the user.
Arbeiten unter Spannung - Isolierende Schlauchleitungen zur Verwendung für hydraulische Geräte und Ausrüstungen
Travaux sous tension - Conduits flexibles isolants avec raccords utilisés avec les outils et matériels hydrauliques
Est applicable aux conduits flexibles isolants avec raccords portables utilisés avec des outils et matériels hydrauliques pour travaux sous tension sur réseaux électriques à fréquence industrielle, de tension nominale supérieure à 1 kV efficace. Ces conduits flexibles isolants avec raccords sont utilisés pour effectuer la connexion entre l'outil hydraulique et la pompe qui sont à des potentiels différents. Ils ne sont pas considérés comme une partie fixe d'un dispositif pour travaux sous tension (par exemple l'élévateur). Ils peuvent être connectés et déconnectés sous une pression négligeable. Ils peuvent être manipulés directement par le travailleur.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment decl
