In order to measure the conductive properties of materials, different techniques are used depending on resistance: 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. As the voice of the U.

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

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. Need more than one copy? 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.
