In order to measure the conductive properties of materials, different techniques are used depending on resistance: Read more about cookies I accept. 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.

This standard is also available to be included in Standards Subscriptions. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.

Properties lengthwise and crosswise may be different if the composite is filled with fibres or flakes, which have been oriented eg during casting. This standard does not purport to address all of the safety problems associated with its use.

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.

Furthermore, DTI have experience with measuring the resistance of composites, rubber and textiles. For composite materials, where it is important to know the conductivity through eg a plate, we have developed techniques for this particular measurement. Need more than one copy?
