ISO 6266:2013 specifies a method for the determination of the fatigue indexes of alpine skis (i.e. the resistance of the skis to changes in shape and of stiffness) after a bending test with cyclic loading.

Skis alpins -- Détermination des indices de fatigue -- Essai en flexion alternée

L'ISO 6266:2013 spécifie une méthode de détermination des indices de fatigue des skis alpins (c'est-ŕ-dire la résistance des skis aux modifications de forme et de raideur) aprčs essai en flexion alternée.

Alpske smuči - Določevanje utrujenosti - Preskus s cikličnim obremenjevanjem

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.

Introduction

Previous investigations showed that the fatigue of an alpine ski is not easy to describe. If one

understands by fatigue the remaining negative change of some characteristics of the ski, influencing the

performance of the ski, as a result of normal use, several tests would be necessary to determine exactly

the susceptibility of a ski to such changes. In addition, some factors may have substantial influence on

the results such as ski length, spring constant, test temperature, kind of vibration, frequency etc. lt was

therefore decided that a test method taking account of all these factors might be of some interest for ski

research but that it should not be proposed for standardization.

Instead of this, a simplified test of the fatigue behaviour of two important characteristics of the ski (i.e.

of camber height and centre spring constant) was proposed for standardization.

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 6266 a été élaborée par le comité technique ISO/TC 83, Matériel de sports et d’activités de plein air,

sous-comité SC 4, Équipements de sport de neige.

Cette deuxième édition annule et remplace la première édition (ISO 6266:1980), qui a fait l’objet d’une

Introduction

Des recherches antérieures ont montré la difficulté de caractériser le phénomène de «fatigue» d’un ski

alpin. Si l’on entend par «fatigue» la modification permanente négative de certaines caractéristiques

du ski, qui influencent son comportement, à la suite d’un usage normal, il est nécessaire de réaliser

plusieurs essais pour déterminer avec certitude la sensibilité du ski à de telles modifications. De plus,

de nombreux facteurs peuvent avoir une influence importante sur les résultats, tels que la longueur du

ski, la raideur en flexion, la température d’essai, la nature des vibrations, la fréquence, etc. Il a donc été

décidé qu’une méthode d’essai, tenant compte de tous ces facteurs, présente un intérêt pour la recherche

relative aux skis, toutefois il convient de ne pas la présenter comme norme.

Au lieu de cela, un essai simplifié de comportement à la fatigue de deux caractéristiques importantes du

ski (c’est-à-dire cambré et raideur globale en flexion) a été présenté comme norme.
