Introduction
Helmets for ski mountaineers are intended to provide protection to the wearer:
— during the ascent, similar to mountaineering, with risk of falling rocks, ice or other objects;
— during the descent, similar to alpine skiing, with the risk of falling onto a surface.
At the time of writing, the ISMF’s (International Ski Mountaineering Federation) “Sporting Rules and
Regulations” require that helmets comply with EN 12492 “Helmets for mountaineers” and EN 1077
class B “Helmets for alpine skiers and snowboarders”. Those requirements lead to insufficient helmet
ventilation during ascent and discomfort for the user during such activities and therefore increases the
risk of the user not wearing the protective helmet. This double certification could preferably be replaced
by a specific standard for ski mountaineers with more relevant requirements.
The intention of this document is to reduce the potential injury risk associated with the hazards but will
not eliminate them completely. No off-crown penetration test has been introduced in this document
because the risk of penetration in ski mountaineering (3.1) is considered low compared to alpine skiing
and hence leads to the possibility of better ventilation.
A proportion of the energy of an impact is absorbed by the helmet, thereby reducing the force of the blow
sustained by the head. The structure of the helmet may be damaged in absorbing this energy and any
helmet that sustains a severe blow needs to be replaced even if damage is not apparent. There are limits
to the amount of protection that can be provided and wearing a helmet cannot always prevent serious
injury, long-term disability or death. A helmet may only be a part of the protection that is required to
carry out this activity.
A list of mountaineering equipment standards is found in informative Annex B.
Angled and tangential (rotational) impacts are one of the causes of head injuries. CEN/TC 158 has
published a new test method, EN 17950:2024. CEN/TC158 WG 13 requires more time to validate the
requirements of the test method which then can be used in future revisions of this document.
1 Scope
This document specifies requirements and test methods for protective helmets for ski mountaineers
intended to protect the head of the user in order to reduce the risk of impact injury.
This document is also applicable to protective helmets used in activities with similar hazards including
but not limited to: ski-touring, speed-touring, ski fitness, split-boarding, skimo and telemark touring, but
does not apply to protective helmets for alpine skiers and snowboarders.
