Cross-country skis -- Determination of elastic properties

ISO 7139:2017 specifies laboratory measurement methods to determine the elastic properties of cross-country skis. Its purpose is to calculate the resistance of defined parts of the ski to bending. ISO 7139:2017 applies to cross-country skis with a nominal length greater than or equal to 150 cm. The standard measurement procedures can be used to ensure comparability between laboratory measurement data, determined and published by ski manufacturers, institutions or others. In ISO 7139:2017, no attempt is made to relate the measurement data to the quality of the ski

Tekaške smuči - Določevanje upogibnih lastnosti

Ta dokument določa metodo za laboratorijsko merjenje upogibnih lastnosti tekaških smuči. Namenjen je izračunu upora določenih delov smuči na upogibanje.
Ta dokument se uporablja za tekaške smuči z nazivno dolžino, večjo ali enako 150 cm. Standardne merilne postopke je mogoče uporabiti za zagotavljanje primerljivosti med podatki laboratorijskih meritev, ki jih ugotovijo in objavijo proizvajalci smuči, ustanove ali drugi. Ta dokument na noben način ne opredeljuje povezovanja merilnih podatkov s kakovostjo smuči.

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 (IEC) en ce qui

concerne la normalisation électrotechnique.

Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont

décrites dans les Directives ISO/IEC, Partie 1. Il convient, en particulier de prendre note des différents

critères d’approbation requis pour les différents types de documents ISO. Le présent document a été

rédigé conformément aux règles de rédaction données dans les Directives ISO/IEC, Partie 2 (voir www

.iso .org/ directives).

L’attention est attirée 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. Les détails concernant

les références aux droits de propriété intellectuelle ou autres droits analogues identifiés lors de

l’élaboration du document sont indiqués dans l’Introduction et/ou dans la liste des déclarations de

brevets reçues par l’ISO (voir www .iso .org/ brevets).

Les appellations commerciales éventuellement mentionnées dans le présent document sont données

pour information, par souci de commodité, à l’intention des utilisateurs et ne sauraient constituer un

engagement.

spécifiques de l’ISO liés à l’évaluation de la conformité, ou pour toute information au sujet de l’adhésion

de l’ISO aux principes de l’Organisation mondiale du commerce (OMC) concernant les obstacles

techniques au commerce (OTC), voir le lien suivant: www .iso .org/ iso/ fr/ avant -propos .html.
