Electrically insulating helmets for use on low voltage installations

This standard is applicable to electrically insulating helmets used for working live or close to live parts on installations not exceeding 1 000 V a.c. or 1 500 V d.c. These helmets, when used in conjunction with other electrically insulating protective equipment prevent dangerous current from passing through persons via their head.

Elektrisch isolierende Helme für Arbeiten an Niederspannungsanlagen

Diese Norm gilt für elektrisch isolierende Helme zum Arbeiten unter Spannung oder in der Nähe unter Span-nung stehender Teile bis AC 1000 V oder DC 1500 V. Diese Helme verhindern bei Verwendung mit anderen elektrisch isolierenden persönlichen Schutz¬aus¬rü¬s-tungen eine gefährliche Körperdurchströmung durch den Kopf.

Casques électriquement isolants pour utilisation sur installations à basse tension

Cette norme est applicable aux casques électriquement isolants utilisés pour le travail sur ou près de parties sous tension d’installations ne dépassant pas 1 000 V en courant alternatif ou 1 500 V en courant continu. Ces casques, lorsqu’ils sont utilisés simultanément à d’autres équipements de protection électriquement isolante, empêchent les courants dangereux de traverser les personnes par la tête.
