要約(英語): According to IEC 62631- 3-2, surface resistivity is defined not only by materials itself but also by the electrode arrangement. We have examined the surface resistance of conductive and antistatic materials using the set of annular electrodes. It was clarified that the guard electrode has adversely affected to the measurements of the surface resistance in case that the material has certain conductivity and the thickness of specimen is less than the gap between the annular electrodes. In order to improve an accuracy of the surface resistance measurements, this paper proposes a quadra-electrode arrangement which has a couple of the annular electrodes set.
