European foreword
This document (prEN 18100:2024) has been prepared by Technical Committee CEN/TC 158 “Head
protection”, the secretariat of which is held by SIS.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a standardisation request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For relationship with Regulation (EU) 2016/425, see informative Annex ZA, which is an integral part of

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.
Angled and tangential (rotational) impacts are one of the causes of head injuries. At the time of developing
this document, no rotational test method was available. Therefore, only linear impacts to a helmeted head
in the shock absorption test have been addressed. CEN/TC 158 will, in the near future, present a new test
method which can be used in future revisions of this document. A helmet may only be a part of the
protection that is required to carry out this activity. A suitable risk assessment should always be carried
out by the wearer to determine if other protective equipment is required e.g. visor.

5 Test methods
5.1 General examination of material and construction
Confirm by reference to appropriate documentation (e.g. materials specification, safety data sheets
relating to the helmet), by normal or corrected vision and/or tactile examination and/or by measurement
of the helmet that it conforms to 4.1.1 and 4.1.2.
oSIST prEN 18100:2024
prEN 18100:2024 (E)
NOTE The following list of documents is given for information and as examples of documents to be examined:
a)  materials specifications;
b)  safety data sheets relating to the materials;
c)  information relating to the suitability of the materials for use with food, in medical devices, or other relevant
applications;
d)  information relating to toxicological, allergenic, carcinogenic, toxic to reproduction or mutagenic investigations
on the materials;
e)  information relating to ecotoxicological and other environmental investigations on the materials.
5.2 Retention system design
Check that the chin strap (3.8) is adjustable in length.
Load the chin strap (3.8) with a force of (250 ± 10) N at a speed of (500 ± 50) N/min and maintain during
(60 ± 10) s. Then measure and record the width of the chin strap (3.8).
5.3 Ventilation test
Check the sum of the minimum cross-sectional area of each ventilation hole, e.g with measuring given in
the 3D file.
The helmet shall be fitted to the headform (3.9) corresponding to the maximum helmet size (3.5) and
adjusted in accordance with 5.5. If applicable, adjustable ventilation hole(s) shall be fully opened before
the test begins. If applicable, any removable thermal liner shall be removed before the test begins. A
(20 ± 0,1) mm diameter steel pin with a length of (100 ± 1) mm shall be inserted using only the weight of
the pin, in all possible directions as deep as possible in each ventilation hole. Report whether or not the
pin contacts the headform (3.9).
