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.

Overview

EN 50365:2002 (CENELEC) specifies requirements for electrically insulating helmets for use on low voltage installations - intended for live working or work close to live parts on systems up to 1 000 V a.c. or 1 500 V d.c. The standard ensures that, when used with other insulating personal protective equipment (PPE), helmets prevent dangerous current from passing through the head. EN 50365 supports essential requirements of EU Directive 89/686/EEC for electrical safety and live working.

Key Topics and Requirements

• Scope & classification
  • Applies to helmets for live working on low voltage installations. Classified as electrical class 0 for the specified voltage limits.
• Harmonised performance base
  • Insulating helmets must also meet the relevant mechanical and general safety requirements of EN 397 (industrial helmets) or EN 443 (firefighter helmets).
• Non-electrical requirements
  • No conductive parts on the shell.
  • Air-conditioning/ventilation holes must prevent accidental contact with live parts and provide IP3X protection.
• Electrical requirements
  • Shells undergo proof-voltage and withstand-voltage tests using a specified water-tank arrangement and test clearances (proof test: d = 20 ± 3 mm; withstand test: d = 40 ± 3 mm).
  • Preconditioning includes mechanical surface treatment and immersion in tap water for at least 24 hours before testing.
  • Proof-voltage applied for a minimum duration (type/sampling tests: typically 3 minutes); absence of puncture or flashover is required.
• Marking & documentation
  • Additional marking: double triangle symbol, class, serial/batch number; symbol in red if colour coding used. Marking must be durable and legible on the peak of the shell.
  • Packaging must protect helmets and be clearly marked (manufacturer, class, size, design).
  • Instructions for use (Annex B) must cover storage, inspection before use, limitations, cleaning, and maintenance.
• Testing, QA and sampling
  • Type and destructive sampling tests are specified; manufacturers should implement ISO 9000-series quality assurance and keep test records. Annexes A–C cover test sequences and sampling.

Applications and Who Uses This Standard

• Safety engineers, PPE manufacturers, test laboratories, procurement teams, and electricians/live-line workers rely on EN 50365 to select, design, certify, and maintain electrically insulating helmets for low-voltage live working. It is essential for organizations that perform live maintenance, utilities, and contractors working on electrical installations.
