Application Summary AI generated
This standard specifies technical requirements and test methods for equipment used to measure resistance to earth in low voltage distribution systems. It applies to testing devices that verify the effectiveness of protective earthing measures in electrical installations operating up to 1000V AC or 1500V DC. The standard is primarily used by electrical safety inspectors and maintenance personnel for on-site verification of grounding systems in industrial, commercial, and residential buildings.
