Application Summary AI generated

This standard specifies DC methods for measuring the surface resistance and surface resistivity of solid insulating materials. It is applied in the electrical and electronics industries for quality control and material characterization of insulating components, such as printed circuit boards, cable insulation, and electrical housings. The standard ensures consistent testing conditions to evaluate how well a material resists surface leakage currents, which is critical for preventing electrical failures in high-voltage or high-humidity environments.
