Surface resistivity
This method is used to determine the surface resistivity of a test specimen.
The volume flows of the insulating material are eliminated using an electrode.

| Test specimen | Ø 80 mm, 2 mm thick |
| Test voltage | Between 1 V and 1.000 V |
| Current measurement | 10-1 A to 10-14 A |
Results of the test method:Surface resistivity σ (sigma). This is the resistance of a square sheet.
