Furthermore, DTI have experience with measuring the resistance of composites, rubber and textiles. Subscription pricing is determined by: 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.

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.
