Volume and Surface Resistivity Measurementsof Insulating Materials Using the Model 6517 AElectrometer/High Resistance MeterIntroductionA fundamental property of insulators is Resistivity . Theresistivity may be used to determine the dielectric breakdown,dissipation factor, moisture content, mechanical continuity andother important properties of a material. The Volume resistivityof some insulators, such as sapphire and Teflon , can be as highas 1016 to 1018 ohm-cm. Because of such large magnitudes,measuring the Resistivity of insulators can be difficult unlessproper test methods and instrumentation are used.
Standard Method Resistivity Tests (Surface and Volume) This test is used to measure the resistivity (surface or volume) of an insulator sample. When used with …
