Definition: resistance expressed in ohms between two electrodes in contact with the surface to be measured

Note 1 to entry: One common configuration (e.g. in IEC 60079-0, Explosive atmospheres – Part 0: Equipment – General requirements) uses parallel electrodes, 100 mm long and 10 mm apart.

Note 2 to entry: The surface resistance is dependent upon the electrode configuration. The surface resistance measured with the example electrode configuration is ten times lower than the surface resistivity.

Note 3 to entry: Conductive rubber strip electrodes are preferred over silver paint electrodes.
