Standards and directives for helmets

Our products meet all the necessary standards, and not just that – we always require that little bit more from our products. This ensures the extra safety that our customers expect from us.

DIN EN 397 – Protection from falling objects

Industrial safety helmets from uvex comply with standard DIN EN 397, which states that they must be designed to protect the wearer from falling objects. Protection against mechanical impacts to the head safeguards the user against possible consequences such as brain injuries or skull fractures. The standard also includes protection against lateral deformation of the helmet, as well as protecting the wearer from dangerous head injuries.

Industrial safety helmets that comply with standard DIN EN 397 generally meet the following basic safety requirements:

Binding requirementsOptional requirements
All helmets certified according to EN 397 must meet these requirements.A helmet certified in accordance with EN 397 may meet these requirements; they are, however, not mandatory requirements.
Shock absorption, verticalVery low temperatures (-20 °C or -30 °C)
Penetration resistance (against sharp and pointed objects)Very high temperatures (+150 °C)
Flame resistanceElectrical insulation (440 V)
Chin strap attachment: chin strap releases at minimum 150N and maximum 250 N Molten metal (MM)
Lateral deformation

EN 50365 – Insulating helmets for use on low voltage installations

Protection against electric shocks and prevention of dangerous electric current passing through the head – requirements:

  • All helmets must also meet the requirements in accordance with EN 397.
  • Protection against alternating voltage of up to 1000 V (AC) or direct voltage up to 1500 V (DC)
  • Insulating helmets must not contain any conductive parts.
  • Air vents (if available) must not allow any accidental contact with live parts.

EN 12492 – Helmets for mountaineers

Protection against hazards that may occur during activities undertaken by mountaineers – requirements:

  • Shock absorption, vertical, frontal, lateral, dorsal.
  • Penetration resistance
  • Carrier element (chin strap releases at min. 500N)
  • Strength of carrier element: Chin strap may exhibit maximum elongation of 25mm
  • Carrier element effectiveness: Helmet must not slide from the head
