This standard describes several general alternative methodologies for measuring resistance or conductance. Link to Active This link will always route to the current Active version of the standard. The procedures appear in the following sections: These individual specific test methodologies would be better able to define the precision and bias for the determination.

Surface resistance or conductance changes rapidly with humidity, while volume resistance or conductance aastm slowly with the total change being greater in some cases. Need help or have a question?

Use Test Method D to evaluate such materials.

From such measurements and the geometric dimensions of specimen and electrodes, both volume and surface resistivity of electrical insulating materials can be calculated, as well as the corresponding conductances and conductivities. The measured value is also affected by the surface contamination.
