Electrical Testing

GEC (Gray’s) performs electrical testing for several industries, including aerospace, automotive, and military. We can thoroughly verify the effective operation of electrical equipment through a range of tests in accordance with applicable standards. See our full list of electrical testing standards.

About Electrical Testing

In industries where the safety and reliability of electronic equipment are non-negotiable, high-quality, professional electrical testing is essential. Electronics can suffer poor performance or failure as a result of temperature, humidity, contamination, mechanical shocks, and other factors. Fortunately, our advanced lab is well-suited to identify electrical vulnerabilities in all kinds of environments.
Our electrical tests can be performed as a standalone service or combined with many of our other environments as part of a larger sequence. We offer multiple types of electrical tests, including (but not limited to):


Measures direct current (DC) resistance of resistors, windings, and conductors.

Insulation Resistance

Measures the total resistance of insulation after applying a stabilized DC voltage across a dielectric.

Thermal Time Transient

Verifies proper attachment of a two-terminal semiconductor die to a mounting substrate or header. Voids, gaps, or improperly placed die could cause premature failure.

Electrostatic Discharge

Tests the transfer of electric charge onto electrical equipment (e.g. static electricity discharge from humans). Temperature and humidity conditions are controlled in our lab to ensure valid results.

Dielectric Withstand Voltage

Verifies the ability of insulation to withstand high voltage tests. In successful tests, the insulation should not breach at specified voltage levels.

Magnetic Effects

Tests for magnetic interference from the device that can affect nearby equipment or sensors such as compasses in aircraft.


Locates faulty switches by verifying whether electricity can pass between two given points in an electric conductor.

The GEC Advantage

In addition to having an established history in providing electrical testing services, GEC has an excellent reputation for service quality. We use the latest processes and technologies in our facility and are ISO 17025 accredited by the A2LA. If our standard processes are not quite what you are looking for, our team can accommodate your needs.
Our expert technicians are very familiar with the value of thorough testing of components. If you would like to learn more about our electrical testing services, contact us today.
