ActiveElectromagnetic compatibility—Testing and measurement techniques—Part 9: Impulse magnetic field immunity test
电磁兼容 试验和测量技术 第9部分：脉冲磁场抗扰度试验
Application Summary AI generated
This standard specifies the immunity requirements and test methods for electrical and electronic equipment subjected to impulse magnetic fields, such as those generated by lightning strikes or switching operations in power systems. It is applied in industrial, commercial, and residential environments to verify that equipment like power supplies, relays, and control panels can withstand transient magnetic disturbances without malfunction. The test is critical for ensuring reliability in substations, railway systems, and heavy machinery installations where high surge currents occur.
