Surface Resistance and Surface Resistivity are the most common tests for measuring the surface of sample material plaques, foams, films, or finished products. These tests are intended to predict the ability to bleed off or retain static charge using industry standard or custom test procedures. Resistivity, when applicable, is calculated from the measured resistance using the dimensions of the electrodes and/or test sample.
Volume Resistance and Volume Resistivity are the most common tests for measuring through the thickness of liquids, powders, sample material plaques, or finished products. These tests are also intended to predict the ability to bleed off or retain static charge using industry standard or custom test fixtures. Resistivity (when appropriate) is calculated from the measured resistance using the dimensions of the electrodes and/or test sample plus the thickness of the sample.
