The updated EN 397:2025 safety helmet standard has now been published, introducing clearer categories for industrial and working at height protection, alongside improvements in impact testing, ergonomics, and ignition resistance. These changes modernise how helmets are certified and help ensure equipment is more closely matched to real work environments.
No Immediate Action Required
There is no rush to update your helmet.
Helmets certified to EN 397:2012+A1:2012 remain valid until their CE or UKCA certification expires. Existing products stay compliant and safe to use within their certified lifecycle.
What’s Changing in EN 397:2025?
The new standard introduces several important updates:
Two Helmet Types
- Type 1: Traditional industrial helmets (similar to current EN 397 products).
- Type 2: Helmets intended for working at height, integrating impact and retention requirements previously only seen in EN 12492.
Updated Impact Testing
- Type 1 helmets are tested for on-crown impact.
- Type 2 helmets are tested for both on-crown and off-crown impact, providing enhanced protection for height environments.
New Chinstrap Release Forces
- Type 1: Must release above 150 N.
- Type 2 Must release above 500 N for greater retention during a fall event.
Electrical Insulation Changes
- Insulation now validated under EN 50365:2023
- Helmets meeting the testing requirements of clause 4.3 of EN 50365:2023 use a single-triangle symbol (non-vented helmets only)
Flammability Test Replaced
- Replaced with a 650°C heated-rod ignition test
New Ergonomic Assessment
- Real wearer moves: turning, bending, looking up/down
- Ensures stability, comfort, and compatibility with accessories
Lateral Deformation Test Removed
- Replaced by more realistic side-impact shock absorption for Type 2
