GB/T 18216.12-2010

This standard specifies the performance requirements and testing methods for devices that measure and monitor electrical parameters (such as voltage, current, and power quality) in low-voltage distribution systems. It is applied to ensure the accuracy and reliability of performance measuring and monitoring devices (PMD) used for verifying protective measures in industrial, commercial, and residential electrical installations operating up to 1000 V AC or 1500 V DC. The standard is particularly relevant for manufacturers, test laboratories, and electrical safety inspectors who need to validate PMD compliance with safety and metrological standards.
