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.

Properties lengthwise and crosswise may be different if the composite is filled with fibres or flakes, which have been oriented eg during casting.

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.
