1) Impact Protection

The helmet must not allow more than 5Kn of energy to spread to the head after a fall of a 5kg weight from a 1 meter height. This test is performed at room temperatures of both +50°C and -10°C.

2) Penetration Protection

The tip of the test mass used (3kg from 1m height) must not come into contact with the skull. This test is performed at room temperatures of +50°C and –10°C.

3) Flammability Protection

The helmet is exposed to a flame and it must not burn with flame emission more than 5 seconds after removal of the flame source.

4) Anchorage

Helmets can only protect when retained on the head. EN 397 requires that either the helmet shell or the headband is fitted with a chinstrap or with the means of attaching one, i.e. anchorage points. Chin strap (where present) shall be released at a force between 15kg–25kg (150N–250N) - due to failure of the anchorages only. Test conducted at +50°C after the helmet being submitted to penetration test.
