GB/T 31838.5-2021 "Solid insulating materials, dielectric and resistive properties, Part 5: Resistance characteristics (DC method) Volume resistance and volume resistivity of impregnated and coating materials", specifies the use of direct current method to determine the volume resistance and volume resistivity of impregnated and coating materials Technical requirements. Clarify the test principle, equipment, sample prepative and test steps, etc., to provide a unified standard for evaluating the resistance performance of such solid insulating materials, which is of great significance for ensuring the insulation mass of electrical equipment.
