NBN EN 16471:2015

This European Standard specifies the minimum requirements for wildland fire fighting helmets protecting the upper head mainly against the effects of impact, penetration, heat, flame and burning embers whilst conducting fire fighting and associated activities in wildland environments. Requirements for marking and information to be supplied by the manufacturer are included. Wildland fire fighting involves direct and indirect attack techniques (like wood cutting). This helmet is not intended to provide protection during fire entrapment.
Wildland environments include forests, crops, plantations and grass/heath/scrub or farmland.
Helmets for use whilst fire fighting in buildings and other structures are not covered by this European Standard (see EN 443).
Protection of the face, eyes, ears and neck may require additional items of PPE, which are not covered by this European Standard.
