IEC 62631-3-4 Dielectric and Resistivity Properties of Solid Insulating Materials, Standard Test for Volume Resistance at Elevated Temperatures

EUROLAB laboratory provides testing and compliance service within the scope of IEC 62631-3-4 standard. This part of IEC 62631 covers procedures for determining the insulation resistance and volume resistance of insulating materials by applying DC voltage and temperatures up to 800°C.

IEC 62631-3-4 Dielectric and Resistivity Properties of Solid Insulating Materials, Standard Test for Volume Resistance at Elevated Temperatures

Typical application materials include high temperature mica sheet and alumina ceramics.

Measurement of volume resistance should be done carefully and taking into account the electrical properties of the measuring circuit and the specific electrical properties of the material. A high voltage is required in most cases to perform the test. Care must be taken to avoid electric shock.

A very stable direct voltage source is required. This can be provided by batteries or a rectified and stabilized power supply. The degree of stability required is that the change in current resulting from any change in voltage is negligible compared to the current to be measured.

EUROLAB assists manufacturers with IEC 62631-3-4 test compliance. Our test experts, with their professional working mission and principles, provide you, our manufacturers and suppliers, the best service and controlled testing process in our laboratories.
