It is the responsibility of the aetm of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to 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. For measurements of surface resistivity, ring electrodes are used as described in the standards.

For composite materials, where it is important to know the conductivity through eg a plate, we have developed techniques for this particular measurement. Contact me Indtast venligst et validt navn. In order to measure the conductive properties of materials, different techniques are used depending on resistance: Your Alert Profile lists the documents that will be monitored.

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. Add to Alert PDF.
