EN 12492: Climbing and mountaineering helmet

EN 397: Helmet for industrial use

These two standards, designed for different environments, have partly common and partly different design and performance requirements. For any helmet to meet and qualify for the standard, it must meet all design and performance requirements.

main difference between two standardsrequirements differences  are:

A.)   Difference in design requirements:

VENTILATION

 

JAW TIE STRENGTH

The requirements in the regulations regarding the chin strap have emerged in proportion to the following working method.

• EN397 standard: Covers work on all kinds of surfaces when feet are on the ground.
• EN12492 standard: Covers work in the air and in space, such as climbing and rope access activities

 

INTERNAL VERTICAL CLEARANCE

B.)   Differences in performance requirements:

SHOCK ABSORPTION REQUIREMENT

This requirement aims to qualify the ability to protect against objects falling on the head and absorb impact while the helmet is worn.

 

PENETRATION REQUIREMENT

 

FLAME RESISTANCE

 

PROTECTION AGAINST MOLTEN METAL SPILL
