What is Arc Resistance Testing at Element?

Arc resistance testing evaluates how insulating materials perform under high-voltage electrical stress. This testing is critical because electrical arcing—when a high-voltage discharge burns across or through an insulator—can lead to failure, fire risks, and serious safety hazards. At Element, we provide comprehensive ASTM D495 testing that subjects material samples to controlled electrical arcing, precisely measuring their ability to resist tracking, carbonization, and potential failure.
