Electrical Measurements

SGS Electrical Measurements test the performance of electrical and electronic components under environmental simulations such as vibration, climatic aging and corrosion. Our tests comply with major original equipment manufacturer (OEM) specifications including BMW, VW, Daimler, Renault and Nissan, PSA, Toyota and many more.

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.

Other Measurements Performed in Our Laboratories

• Ground continuity
• The rebound time of a switch
• Heating temperature
