L'ISO 7331:2005 spécifie les exigences minimales de sécurité des bâtons de ski alpin et donne les méthodes d'essai permettant de vérifier la conformité à ces exigences. Elle s'applique aux bâtons de skis pour le ski alpin dans les gammes suivantes de longueurs totales: groupe A, plus grandes ou égales à 1 050 mm (bâtons pour adultes); groupe B, plus petites que 1 050 mm mais plus grandes ou égales à 700 mm (bâtons pour adolescents); groupe C, plus petites ou égales à 700 mm (bâtons pour enfants).

Palice za alpsko smučanje - Zahteve in preskusne metode

Ta mednarodni standard določa minimalne zahteve za varnost palic za alpsko smučanje in podaja preskusne metode za preverjanje skladnosti s temi zahtevami. Velja za palice za alpsko smučanje v naslednjih razponih skupne dolžine lT (glej klavzulo 3): - skupina A, lT W 1050 mm (palice za odrasle); – skupina B, 1050 mm > lT W 700 mm (palice za mladostnike); skupina C, lT u 700 mm (otroške palice – igrače). Posebni modeli lahko odstopajo od tega mednarodnega standarda, vendar morajo biti trajno označeni kot posebni modeli (glej točko 8.2).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 7331 was prepared by Technical Committee ISO/TC 83, Sports and recreational equipment,

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
L'attention est appelée sur le fait que certains des éléments du présent document peuvent faire l'objet de
droits de propriété intellectuelle ou de droits analogues. L'ISO ne saurait être tenue pour responsable de ne
pas avoir identifié de tels droits de propriété et averti de leur existence.
L'ISO 7331 a été élaborée par le comité technique ISO/TC 83, Matériel de sports et d'activités de plein air,
sous-comité SC 3, Fixations de ski.
Cette troisième édition annule et remplace la deuxième édition (ISO 7331:1990), dont les Articles 1 et 8 ainsi
que 7.4, 7.5.2, 7.5.3, 7.5.6, 7.6.3, 7.7.3, 7.8.4 ont fait l'objet d'une révision technique.

6 Échantillons pour essai
Pour l'essai, trois bâtons parmi les plus longs et trois bâtons parmi les plus courts d'un groupe doivent être
envoyés au laboratoire d'essai comme échantillons pour essai.
En plus, pour l'essai du groupe A, trois bâtons d'une longueur de 1 200 mm, et pour l'essai du groupe B, trois
bâtons d'une longueur de 1 000 mm doivent être envoyés au laboratoire d'essai.
Un bâton long et un bâton court doivent être choisis pour les essais conformément de 7.2 à 7.9.2.
Si l'un des échantillons ne satisfait pas à ces essais, les essais peuvent être répétés avec deux autres
échantillons, qui doivent alors tous les deux satisfaire aux essais.
7 Exigences et méthodes d'essai
7.1 Longueur totale
7.1.1 Exigence
La longueur totale, l , ne doit pas s'écarter de la longueur donnée de plus de ± 10 mm. En outre, les
T
longueurs des deux bâtons d'une même paire ne doivent pas varier de plus de 7 mm.
7.1.2 Essai
Déterminer les longueurs de tous les échantillons pour essais indiqués dans l'Article 6.
7.2 Forme extérieure
7.2.1 Exigence

7.3 Dispositif antiaccrochage
7.3.1 Exigence
Le bâton de ski doit être conçu de manière à limiter la force qui peut être transmise au poignet et au bras du
skieur lorsque le bâton est entravé au cours de la pratique du ski. Une conception, conformément à 7.6.3 ou à
7.8.4, ou une poignée sans dragonne, permettent de satisfaire à cette exigence.
7.3.2 Essai
Soumettre à essai, conformément à 7.6.3 ou à 7.8.4, ou à un examen visuel et un contrôle de fonctionnement.
