Plastics are tested electrically to see how well they behave as conductors or insulators and how well they can tolerate electrical stress. Important electrical characteristics are evaluated, including tracking resistance, surface resistivity, volume resistivity, and dielectric strength. These tests guarantee that plastic materials are appropriate for electrical and electronic applications, avoid malfunctions, and adhere to safety regulations.
