Application Summary AI generated

This standard specifies the test method for measuring the volume resistivity of semi-conducting rubber and plastic materials used in electric cables and wires. It is applied in quality control and material verification for power cables, particularly for semi-conductive shielding layers in medium and high voltage cables. The test ensures these materials meet required electrical conductivity standards to prevent partial discharge and ensure cable reliability.
