Light conveyor belts. Determination of electrical resistancesWhat is ISO 21178 about? ISO 21178 specifies test methods for determining the electrical resistances of light conveyor belts according to ISO 211831. 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 also specifies two test methods for determining the surface resistivity and the volume resistivity. Who is ISO 21178 for? ISO
