EN 61000-4-16 & IEC 61000-4-16

EN 61000-4-16 and IEC 61000-4-16- Electromagnetic compatibility (EMC) – Part 4-16: Testing and measurement techniques – Test for immunity to conducted, common mode disturbances in the frequency range 0 Hz to 150 kHz.

EN 61000-4-16 and IEC 61000-4-16 concern themselves with the immunity of electrical and electronic equipment to conducted, common-mode (CM) disturbances in their external cables, at 0Hz (DC) and over the frequency range 15Hz to 150kHz.

EN 61000-4-16 and IEC 61000-4-16 have been adopted as the harmonized EU standard EN 61000-4-16. Both the EN & IEC standard contains the basic test methods by-product and generic standards listed under Electromagnetic Compatibility (EMC) Directive 2014/30/EU.

During testing to this standard, one must 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. Conducted, common mode disturbances can originate from power line currents and return leakage currents in the earthing/grounding system.

Interference due to these disturbance phenomena is most commonly found in industrial plants. If your product is intended for use in this environment, testing to this standard is very important and usually required for the safe operation of your product.

EN 61000-4-16 and IEC 61000-4-16 are basic test standards. When you are self-declaring conformity, it need not be listed on a product’s EMC Declaration of Conformity.

Equipment Guidelines

Generally NOT RequiredGenerally Required
  • Marked for usage in Residential, Commercial, and Light industrial Areas.
  • Ports that are not likely subject to EM phenomena (cables less than 20m).
  • Equipment intended for use in aircraft and other applications powered by 400Hz
  • Disturbances produced by 400 Hz mains systems. [1]
  • Equipment subject to conducted disturbances generated by intentional radio-frequency transmitters. [2]
  • Marked for usage in industrial areas.
  • Telephone cables connected to the public telephone network
    • Other types of signals, control, data cables that exceed 20m in length.

[1] The immunity to harmonics and interharmonics, including mains signaling, on a.c. power ports (in differential mode) are covered by IEC 61000-4-13 and IEC 61000-4-19.

[2] The immunity to conducted disturbances generated by intentional radio-frequency transmitters is covered by IEC 61000-4-6.
