Testing procedure: Shock Absorption Test – A 5kg rounded striker is dropped on the crown of the helmet from 1m. The force transmitted to the head form cannot exceed 5KN. Resistance to Penetration Test – 3kg pointed striker dropped on the crown region, striker not allowed to contact the head form. Resistance to Flame Test – when exposed to a flame for 10 seconds and then removed, the shell must not set alight or self-extinguish within 5 seconds. The relevant European standard can be found on the safety helmet, usually underneath the peak of the helmet so in this case look out for a EN397 standard for confirmation of performance.
