The methods described above are not limited to measurements on polymer materials; they are also well suited for other materials with a comparable conductivity, ie. In order to measure the conductive properties of materials, different techniques are used depending on resistance: Part of the equipment for volume and surface resistance Measurements.

For composite materials, where it is important to know the conductivity through eg a plate, we have developed techniques for this particular measurement.

These measurements are carried out in a climatic test cabinet where the temperature and humidity can be varied over a large range, so other conditions are also posible. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

As the voice of the U. 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. We have no amendments or corrections for this standard. Your Alert Profile lists the documents that will be monitored. Properties lengthwise and crosswise may be different if the composite is filled with fibres or flakes, which have been oriented eg during casting.
