The requirements for helmets according to EN 12492 are: If a helmet is certified according to EN 12492, it must protect its wearer from the dangers of mountaineering.

​

The following requirements must be met if helmets are certified according to EN 12492:

• They must be shock-absorbing vertically, frontally, laterally and dorsally.
  For this purpose, on the one hand an impact body is dropped vertically from above, and on the other hand a flat steel plate is dropped obliquely from above (front, side, rear) onto the helmet from a defined distance.

• A certain penetration resistance must be ensured.

• They need a supporting system, which means a chin strap which releases at min. 500 N, has a max. elongation of 25 mm and ensures that the helmet does not slide off the head.
