Light conveyor belts - Determination of electrical resistances (ISO 21178:2005)

ISO 21178:2005 specifies test methods for determining the electrical resistances of light conveyor belts according to ISO 21183-1. The resistances are surface resistance, volume resistance perpendicular to the belt plane, and longitudinal and transverse volume resistance parallel to the belt plane. ISO 21178:2005 also specifies two test methods for determining the surface resistivity and the volume resistivity.

Leichte Födergurte - Bestimmung der elektrischen Widerstände (ISO 21178:2005)

Diese Europäische Norm legt Prüfverfahren zur Bestim¬mung der elektrischen Widerstände leichter Fördergurte fest, wie sie in ISO 21183-1 beschrieben sind. Die Widerstände sind der Oberflächenwiderstand, der Durchgangswiderstand senkrecht zur Gurtoberfläche und der Durchgangswider¬stand in Längs- und Querrichtung parallel zur Gurtober¬fläche. Des Weiteren sind in dieser Norm zwei Verfahren zur Ermittlung des spezifischen Oberflächenwiderstan¬des und des spezifischen Durchgangswiderstandes ent¬halten.

Courroies transporteuses légères - Détermination des résistances électriques (ISO 21178:2005)

L'ISO 21178:2005 spécifie des méthodes d'essai permettant de déterminer les résistances électriques des courroies transporteuses légères décrites dans l'ISO 21183-1. Ces résistances sont la résistance surfacique, la résistance volumique perpendiculaire au plan de la courroie et la résistance volumique dans les sens longitudinal et transversal, parallèlement au plan de la courroie. L'ISO 21178:2005 spécifie également deux méthodes d'essai pour déterminer la résistivité surfacique et la résistivité volumique.
