BS EN 61000-4-16:2016

What is BS EN 61000-4-16- Electromagnetic compatibility (EMC) testing and measurement techniques about? 

BS EN 61000-4-16 is a safety standard on Electromagnetic compatibility (EMC). 

BS EN 61000-4-16 relates to the immunity requirements and test methods for electrical and electronic equipment to conduct, common mode disturbances in the range d.c. to 150 kHz. 

The object of BS EN 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. 

BS EN 61000-4-16 defines: 

• Test voltage and current waveform 
• Range of test levels 
• Test equipment 
• Test set-up 
• Test procedures 

The test 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. 

Note: 1: The disturbances produced by 400 Hz mains systems are not included in the scope of BS EN 61000-4-16. 

Note 2: This test is not relevant for equipment ports intended to be connected to short cables, having a length less than 20 m or less. 

Note 3: The immunity to harmonics and inter harmonics, including mains signalling, on a.c. power ports (in differential mode) are not included in the scope of BS EN 61000-4-16 and is covered by IEC 61000-4-13 and IEC 61000-4-19. 

Note 4: The immunity to conducted disturbances generated by intentional radio-frequency transmitters is not included in the scope of BS EN 61000-4-16 and is covered by IEC 61000-4-6. 

Who is BS EN 61000-4-16- Electromagnetic compatibility (EMC) testing and measurement techniques for?  

BS EN 61000-4-16 on test for immunity to conducted, common mode disturbances in the frequency range 0 Hz to 150 kHz is relevant to: 

• Electromagnetic engineers 
• Immunity testing authorities 

Why should you use BS EN 61000-4-16- Electromagnetic compatibility (EMC) testing and measurement techniques? 

BS EN 61000-4-16 is part of the IEC 61000 series. 

BS EN 61000-4-16 describes the testing and measurement techniques. BS EN 61000-4-16 is an international standard that gives immunity requirements and test procedures related to conducted, common mode disturbances in the range d.c. to 150 kHz. BS EN 61000-4-16 provides guidance on diverse types of test equipment, devices, and their functions. BS EN 61000-4-16 also provides guidance on the test voltage which is applied in the common-mode to power supply, control, signal, and communication ports (the differential mode voltage is dependent on the circuit unbalance). The test generator typically consists of a waveform generator capable of covering the frequency band of interest. 

Overall, BS EN 61000-4-16 is useful as it assists with the test method and measurement techniques for immunity to conducted, common mode disturbances in the frequency range 0 Hz to 150 kHz. 

What’s changed since the last update? 

BS EN 61000-4-16:2016 supersedes BS EN 61000-4-16:1998+A2:2011 which will be withdrawn on 13 January 2019. 

BS EN 61000-4-16:2016 replaces the first edition published in 1998, Amendment 1:2001 and Amendment 2:2009. BS EN 61000-4-16:2016 constitutes a technical revision. 

BS EN 61000-4-16:2016 includes the following significant technical changes with respect to the previous edition: 

• Clarification and complement of test generators' specifications and performances
