Electrical conductivity in materials – Measuring technique

This standard is also available to be included in Standards Subscriptions. For composite materials, where it is important to know the conductivity through eg a plate, we have developed techniques for this particular measurement.

Specific precautionary statements are given in. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

Part of the equipment for volume and surface resistance Measurements. At higher conductivity, where the contact resistance becomes significant, 4-point measurements are done with a Keithley SourceMeter to determine the resistivity in the materials.

For measurements of surface resistivity, ring electrodes are used as described in the standards. Read more about cookies I accept. You may delete a document from your Alert Profile at any time. Please first verify your email before subscribing to alerts. Your Contact Jakob S.
