Steel cord conveyor belts — Longitudinal traction test — Part 2: Measurement of tensile strength

ISO 7622-2:2015 specifies a method for the determination of the tensile strength, in the longitudinal, of steel cords constituting the carcass of conveyor belts. It applies exclusively to conveyor belts with a steel carcass. NOTE A method for the determination of elongation is specified in ISO 7622‑1.

Courroies transporteuses à câbles d'acier — Essai de traction dans le sens longitudinal — Partie 2: Mesurage de la résistance à la rupture

ISO 7622-2:2015 a pour objet de vérifier, à l'aide d'un essai destructif, la résistance à la rupture des câbles d'acier constituant la carcasse des courroies transporteuses. S'agissant d'un essai destructif, il n'est utilisé qu'en cas de litige ou en l'absence de certificats de conformité délivrés par le fabricant de câbles.

Introduction

This test method is intended to verify, by destructive testing, the tensile strength of steel cords

constituting the carcass of conveyor belts. As it is a destructive test, it is used only in the event of

litigation or where no certificate of compliance is issued by the cord manufacturer.

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 maintenance

ultérieure sont décrites dans les Directives ISO/IEC, Partie 1. Il convient en particulier de noter les

différents critères d’approbation nécessaires 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).

Le présent document a été élaboré par le comité technique ISO/TC 41, Poulies et courroies (y compris

les courroies trapézoïdales), sous-comité SC 3, Courroies transporteuses, en collaboration avec le

comité technique CEN/TC 188, Courroies transporteuses, du Comité européen de normalisation (CEN),

conformément à l'accord de coopération technique entre l'ISO et le CEN (Accord de Vienne).

Cette troisième édition annule et remplace la deuxième édition (ISO 7622-2:2015), qui a fait l’objet d’une
