What is EN 50365?

Understanding the Standard for Electrically Insulating Helmets

EN 50365:2002 is a European standard that applies to electrically insulating helmets used when working on live installations up to 1000 volts AC or 1500 volts DC.

Helmets certified to EN 50365 must pass stringent electrical insulation tests, including exposure to 10,000 volts, to ensure they provide sufficient protection in environments with live electrical hazards.

To meet the EN 50365 standard, a helmet must also comply with the requirements of either:

  • EN 397 – Industrial Safety Helmets, or
  • EN 443 – Helmets for Firefighters

Helmets certified to this standard are marked with the 'double triangle' symbol, indicating their electrical insulating properties, along with the class of the helmet.

This standard is essential for those working in high-voltage environments, ensuring additional protection beyond standard industrial safety helmets.
