This document specifies test methods for determining the electrical resistances of light conveyor belts according to ISO 21183-1<\/span><\/span>. The resistances are surface resistance, volume resistance perpendicular to the belt plane, and longitudinal and transverse volume resistance parallel to the belt plane. This document also specifies two test methods for determining the surface resistivity and the volume resistivity.<\/p>\n
