IEC 61000-4-16 Testing – Immunity to Conducted

IEC 61000-4-16 relates to the immunity requirements and test methods for electrical and electronic equipment to conducted, common mode disturbances in the range d.c. to 150 kHz. The scope of IEC 61000-4-16 is to establish a common and reproducible basis for testing electrical and electronic equipment with the application of common mode disturbances to power supply, control, signal and communication ports.

IEC 61000-4-16 defines:

  • test voltage and current waveform;
  • range of test levels;
  • test equipment;
  • test set-up;
  • test procedures.

IEC 61000-4-16 is intended to demonstrate the immunity of electrical and electronic equipment when subjected to conducted, common mode disturbances such as those originating from power line currents and return leakage currents in the earthing/grounding system.

The disturbances are typically generated by

  • the power distribution system, with its fundamental frequency, significant harmonics and interharmonics;
  • power electronic equipment (e.g. power¬†converters), which may inject disturbances into the ground conductors and earthing system (through stray capacitance or filters), or generate disturbances in signal and control lines by induction.

IEC 61000-4-16 defines the test procedures for both the categories of disturbance defined above.
