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

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. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. This standard is not included in any packages.

In order to measure the conductive properties of materials, different techniques are used depending on resistance: Subscription pricing is determined by: 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 does not purport to address all of the safety concerns, if any, associated with its use.

For measurements of surface resistivity, ring electrodes are used as described in the standards. Agilent B Resistivity Cell for measurement on flat samples: This standard is also available to be included in Standards Subscriptions. Furthermore, DTI have experience with measuring the resistance of composites, rubber and textiles. Proceed to Checkout Continue Shopping. Specific precautionary statements are given in.
