EN 397:2025 – What You Need to Know About the New Industrial Helmet Standard

The EN 397 industrial helmet standard has undergone its most significant update in 30 years. First introduced in 1995, the standard is now updated to EN 397:2025, reflecting modern workplace risks and technological advancements. For employers and safety officers, understanding these changes is crucial to ensuring staff are protected on-site.

Key Changes in EN 397:2025:

1. Two Helmet Types for Better Protection

• Type 1 helmets: Absorb impacts to the crown area, similar to the previous EN 397:2012 standard. Chinstraps are optional.

• Type 2 helmets: Provide all-round impact protection, including off-crown impacts. Chinstraps are mandatory, with higher retention testing.

2. Expanded Performance Options

• Off-crown penetration resistance (OCP): Lateral impact protection for both helmet types.

• Electrical protection: Updated to EN 50365:2023, covering up to 17kV.

• Enhanced visibility & electrostatic properties: Ensures safety in all lighting conditions and ATEX zones.

• Temperature conditioning: Helmets can now be tested below -20°C without custom specs; +150°C upper limit remains.

3. Compatibility & Ergonomics

• Attachments (visors, face shields, ear defenders) are tested for safety and compatibility, ensuring comfort and proper fit.

• Helmets must now pass ergonomics and mobility assessments, guaranteeing usability with accessories.

4. Risk Assessment Becomes Even More Critical

With two helmet types and multiple performance options, employers must carefully assess hazards before selecting helmets. EN 397:2025 makes it easier to match helmet type and features to the workplace risk.

Practical Implications for Employers

• There’s no immediate rush to update helmets – EN 397:2012 certifications remain valid until expiry.

• Dual certification is possible during the transition period.

• Multi-directional impact resistance and standardized accessory compatibility improve overall worker safety.
