Surface and volume resistivity of plastics
These analyses (IEC 62631-3-1 and IEC 62631-3-2) measure the resistive properties of solid plastics under direct current (DC) conditions.
Flat plates of the sample are placed between two electrodes, and a known DC voltage is applied. For volume resistivity (IEC 62631-3-1), the current flowing through the bulk material is measured. For surface resistivity (IEC 62631-3-2), the current along the surface is measured. Resistivity values are calculated from the applied voltage and measured current.
The tests are conducted in triplicate at 23 °C and 50% RH after conditioning the samples for 4 days at 23 °C and 50% RH. The samples sent for testing should have a thickness close to their intended application.
Analyses conducted at cryogenic and elevated temperatures (up to 250°C) are also available, as well as other electrical tests for plastic materials. Please contact our experts for a quote tailored to your project.
