We work to global standards including ISO and IEC, to test for:
- Resistivity: Surface and/or transverse resistivity measurements are used to characterize the ability of a material to conduct electricity.
- Contact Resistance Measurement: Resistance generated by a contact, or a crimping, can cause the destructive heating of a connector. We measure such resistance using a direct current source and a microvoltmeter.
- ElectroStatic Discharge (ESD): A high voltage generator, a charge bar and an electrostatic field meter evaluate dissipation (or not) of these charges in a part.
- Dielectric Strength: These tests verify the maximum value of the electric field that a material can withstand before the triggering of an electric arc, thus a short circuit.
- Insulation Resistance: Measuring insulation resistance in electrical equipment allows manufacturers to identify potentially damaging faults or defects.
- Electrical Continuity: These tests check an electrical component remains operational when subjected to severe environmental conditions.
