Steel cord conveyor belts - Longitudinal traction test - Part 1: Measurement of elongation (ISO 7622-1:1984)

This part specifies a method for the determination of the elongation of steel cords constituting the carcase of conveyor belts, when subjected to a force corresponding to 10 % and to 60 % of the specified tensile strength. Applies exclusively to conveyor belts with a steel carcase.

Stahlseilfördergurte - Zugversuch in Längsrichtung - Teil 1: Dehnungs-Messung in Längsrichtung (ISO 7622-1:1984)

Dieser Teil von ISO 7622 beschreibt ein Verfahren, um die Dehnung der Stahlseilein der Karkasse eines Fördergurtes zu bestimmen, wobei sie einer Kraft unterworfen werden, die 10% und 60% der spezifizierten Seilbruchkraft entspricht. Es wird ausschließlich bei Stahlseilfördergurten angewendet. Anmerkung - Ein Verfahren zur Bestimmung der Zugfestigkeit ist in ISO 7622/2 beschrieben.

Courroies transporteuses à câbles d'acier - Essai de traction dans le sens longitudinal - Partie 1: Mesurage de l'allongement (ISO 7622-1:1984)

La présente partie de l'ISO 7622 spécifie une méthode de détermination de l'allongement des câbles d'acier constituant la carcasse des courroies, soumis à un effort correspondant à 10 % et à 60 % de la résistance à la rupture spécifiée. Elle s'applique exclusivement aux courroies transporteuses à câbles d'acier.
NOTE -- Une méthode de détermination de la résistance est spécifiée dans l'ISO 7622/2.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of preparing International
Standards is normally carried out through IS0 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, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council. They are approved in accordance with IS0 procedures requiring at
least 75 % approval by the member bodies voting.
International Standard IS0 7622/l was prepared by Technical Committee lSO/TC 41,
Pulleys and belts (including veebelts).
