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.

La formation d'électricité statique, fonction de la résistance électrique des matériaux, est parfois à l'origine d'inflammation et présente donc un risque d'incendie. Le présent document spécifie des méthodes d'essai pour mesurer les résistances électriques surfaciques et volumiques des courroies transporteuses légères.
ISO 21178:2013 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 21178:2013 also specifies two test methods for determining the surface resistivity and the volume resistivity.
