Industrial Safety Helmets | uvex
The industrial safety helmets manufactured by uvex are engineered to adhere to the DIN EN 397 standard, which dictates that these helmets must offer protective features against falling objects. This protection against mechanical impact helps in preventing severe outcomes such as traumatic brain injuries or skull fractures for the users. Furthermore, this standard ensures that there is resistance to lateral deformation, providing an extra layer of defense against hazardous head injuries.
For further details, you may refer to our website for more information.
Typically, industrial safety helmets that comply with the DIN EN 397 standard are built to ensure the following primary safety criteria:
- Shock Absorption
which is essential for defending against the impact of falling objects or suspended loads. - Resistance to Penetration
to protect the head from potential hazards like liquid splashes and dirt. - Flame Resistance.
- Fit Assurance
achieved partly through an adjustable interior, and in certain cases, through the installation of a chin strap according to its designated usage area.
Deciphering European Helmet Certification
EN:
Helmet for climbing and mountaineering
EN 397:
Helmet designated for industrial application
Both these standards are tailored for specific environments, each outlining distinctive design and performance metrics.
To satisfy a certification, the helmet must fulfill all outlined specifications.
Each standard enforces varying design specifications, which can hinder dual certification and suggest partial adherence to both standards.
Below are the essential design requirement distinctions between the two standards:
1. Design Requirement Distinctions
VENTILATION
EN:
Minimum ventilation area
exceeding 4 cm²
EN 397:
Maximum ventilation area
not surpassing 4.5 cm²
HOW DOES THIS AFFECT MY HELMET?
- EN: compliant models include STRATO VENT / VERTEX VENT
- EN 397: compliant models include STRATO / VERTEX / VERTEX VENT with shutters secured
CHINSTRAP RESILIENCE
EN:
Chinstraps must exceed
a strength of 50 kg to minimize the risk of detachment during a fall.
EN 397:
Chinstraps must be less than 25 kg in strength to mitigate strangulation risks if the helmet gets snagged.
Depending on regulatory specifications, EN 397 generally covers ground-level work while the EN standard pertains to elevated work environments.HOW DOES THIS AFFECT MY HELMET?
- By utilizing a DUAL chinstrap on the STRATO and VERTEX lines, one can modify the chinstrap strength based on the anticipated hazards in their working environment (see technical tip for dual chinstrap).
INTERNAL VERTICAL CLEARANCE
EN:
EN 397:
The EN 397 standard stipulates that the internal vertical space must not fall below 25 mm.
HOW DOES THIS AFFECT MY HELMET?
- Due to this regulation, helmets featuring a liner, like the STRATO models, cannot fulfill the requirement.
2. Performance Requirement Differences
SHOCK ABSORPTION REQUIREMENT
Should you seek to gather more details, please explore our website Wei Guang.
This requirement aims to evaluate the helmet's capacity to shield the head from falling objects.
EN:
Impact force
F ≤ 10 kN
EN 397:
Impact force
F ≤ 5 kN
PENETRATION REQUIREMENT
EN:
Penetration
No head contact with the impact point
EN 397:
Penetration
No head contact with the impact point
HOW DOES THIS AFFECT MY HELMET?
- All helmets in the Petzl VERTEX and STRATO lines satisfy the tests regarding impact absorption capacity and penetration.
FLAME RESISTANCE
EN:
EN 397:
Exposure for 10 seconds at a distance of 5 cm
Specification: must cease burning within 5 seconds following flame removal
HOW DOES THIS AFFECT MY HELMET?
- STRATO and VERTEX helmets, including VERTEX VENT helmets with secured shutters, all pass these assessments.
PROTECTION FROM MOLTEN METAL SPLASH
EN:
EN 397:
No penetration from molten metal
Burn duration limited to 5 seconds
HOW DOES THIS AFFECT MY HELMET?
- STRATO and VERTEX helmets, alongside VERTEX VENT helmets with secured shutters, meet the applicable tests.
Conformance with the EN Electrical Standard:
EN:
Electrically insulated helmet suitable for low-voltage environments.
To be compliant with EN, a helmet must first adhere to all stipulations outlined in EN 397.
HOW DOES THIS AFFECT MY HELMET?

- Only the VERTEX model fulfills the EN standard requirements. The STRATO helmet does not conform to EN as it fails to meet certain EN 397 specifications (e.g., internal vertical clearance).
