Electrical conductivity in materials – Measuring technique – Danish Technological Institute

At higher conductivity, where the ast resistance becomes significant, 4-point measurements are done with a Keithley SourceMeter to determine the resistivity in the materials. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Properties lengthwise and crosswise may be different if the composite is aastm with fibres or flakes, which have been oriented eg during casting.

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

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. For measurements of surface resistivity, ring electrodes are used as described in the standards.
