European Standards for Helmet and Bump Caps

EN 397 - Helmets for general use in industry to provide protection to the wearer against falling objects and consequential brain injury and/or skull fracture.

EN 812 - Bump Caps provide protection to the wearer against the effects of striking head/scalp against hard or sharp stationary objects. Not intended to provide protection against effects of falling, thrown objects, moving or suspended loads.

Mandatory tests:
Shock Absorption / Impact Resistance EN 397 Safety Helmets EN 812 Bump Caps
Drop height 1 metre 0.25 metre
Maximum force allowed 5 kiloNewtons 15 kiloNewtons
Energy Transmitted during test 49 joules 12 joules
Striker face and weight 50mm radius hemispherical, 5kg 100mm diameter flat, 5kg
Penetation Resistance EN 397 - Safety Helmets EN 812 - Bump Caps
Drop height 1 metre 0.5 metre
Energy Transmitted during test 29 joules 2.5 joules
Striker mass 3kg 0.5kg
Optional Tests:             * Helmet and plastic bump cap only (not baseball Caps)
Lateral Deformation (LD)
Provides a level of protection against lateral compression, indicating improved side strength of helmet.
Test Method:
A pressure of 43kg is applied on both sides of the shell for a given period of time and then the amount of
helmet deformation is measured.
Low Temperature Performance (-20°C/-30°C)
Helmet will still provide EN 397/812 protection when worn at or above this temperature.
Test Method:
The mandatory shock absorption and penetration resistance tests are repeated at stated low temperatures.
Electrical Insulation* (440V a.c)
Test indicates protection from electrical shock.
Test Method:
The shell is immersed for 24 hours in 3 grams per litre of salt water. A current is passed through electrodes
which are positioned both inside and outside the helmet. The maximum electrical leakage allowed is 1.2mA
for 15 seconds at 1200kV ac.
Molten Metal* (MM)
The test ensures that there is no penetration of molten metal splash, indicating a quality, heat resistant shell.
Test Method: Test procedure is 150g of molten iron dropped onto a 50mm radius area on helmet crown.
Extra Features outside the scope of EN 397 (-40°C & 1000V a.c)
Purpose and test method is as per the relevant EN 397 options detailed above, but performance indicates a
higher level of protection.
