In the most significant change to industrial helmet specifications for 30 years, the new EN 397:2025 Industrial Protective Helmet standard has been released.
What’s new with EN 397:2025?
EN 397:2025 brings key changes to performance, design and compatibility, plus several all-new requirements.
Key changes
Under the new EN 397:2025 standard, helmets will be assessed as either Type 1 or Type 2 with different performance requirements applicable to each.
The 440V electrical properties option has been removed and electrically insulating helmets must now be tested to EN 50365:2023.
Attachments and accessories, such as visors, ear defenders or helmet lamps, that may affect conformity of the helmet have to be fitted for specified tests. A new ergonomics and mobility requirement also assesses fit and operation.
Some test methods have been updated to make them more repeatable, including shock absorption and penetration resistance which now specify velocity instead of drop height.
There are several all-new options applicable to both helmet types. Off-crown penetration resistance, enhanced visibility and electrostatic dissipative properties options have been added, while the old lateral deformation test has been removed.

What happens next?
There is no rush to update your helmet to the new standard – EN 397:2012 helmets can continue to be used and sold until the CE/UKCA certificate expires.
