European foreword
This document (EN 958:2024) has been prepared by Technical Committee CEN/TC 136 “Sports,
playground and other recreational facilities and equipment”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by December 2024, and conflicting national standards shall
be withdrawn at the latest by December 2024.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 958:2017.
a) in the scope, energy absorbing systems (EAS) according to this document have been limited to users
weighing not less than 40 kg (total weight without equipment) and no more than 120 kg (total weight
including the equipment) and the use is limited on via ferrata according to EN 16869:2017;
b) modification of the maximum impact force in 4.2.3 a);
c) modification of the mass in 4.2.3 b);
d) modification of the test apparatus and the test method for the dynamic performance;
e) the manufacturer’s instructions and information take into account the previous modifications, the
EAS disinfection and the progression in a rope party is also recommended for children.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
via ferrata
route, generally on rocky terrain, consisting of a fixed climbing installation including a safety line where
the user is not supervised
[SOURCE: EN 16869:2017, 3.1]
Note 1 to entry: The mere presence of a wire cable/rope on a mountain route does not constitute a via ferrata
(e.g. Hörnli Ridge on Matterhorn).
3.2
safety line
flexible or rigi
