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. Subscription pricing is determined by: Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

For measurements of surface resistivity, ring electrodes are used as described in the standards. If the document is revised or amended, you will be notified by email. Standards Subsctiption may be the perfect solution. Furthermore, DTI have experience with measuring the resistance of composites, rubber and textiles.

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. Agilent B Resistivity Cell for measurement on flat samples: Properties lengthwise and crosswise may be different if the composite is filled with fibres or flakes, which have been oriented eg during casting.
