BS EN 61000-4-39:2017

What is BS EN 61000-4-39 - Electromagnetic compatibility (EMC) about ?  

BS EN 61000-4-39 is the fourth part of an international standard used for Electromagnetic compatibility (EMC). BS EN 61000-4-39 specifies immunity requirements for electrical and electronic equipment when it is exposed to radiated electromagnetic energy from RF transmitters used in close proximity.  

BS EN 61000-4-39 establishes test levels and the required test procedures. The applicable frequency range is 9 kHz to 6 GHz. Fixed-installation equipment being exposed to portable transmitting devices, mobile equipment exposed to fixed transmitting devices and mobile equipment exposed to other mobile transmitting devices are considered. 

Note 1: In the context of BS EN 61000-4-39, “close proximity” generally refers to a separation distance between the source and victim equipment of less than or equal to 200 mm for frequencies greater than 26 MHz and 500 mm for frequencies lower than 26 MHz. 

Note 2: As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard should be applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria. TC 77 and its sub-committees are prepared to co-operate with product committees in the evaluation of the value of particular immunity tests for their products. 

Who is BS EN 61000-4-39 - Electromagnetic compatibility (EMC) for ? 

BS EN 61000-4-39 on Electromagnetic compatibility (EMC) is useful for: 

• Manufacturers of electronic devices 
• Manufacturers of automotive parts 
• Electronic engineers 
• Manufacturers of electronic circuits 

Why should you use BS EN 61000-4-39 - Electromagnetic compatibility (EMC) ?  

BS EN 61000-4-39 is useful the selecting the frequencies or frequency bands for immunity testing. BS EN 61000-4-39 helps in characterizing the radiating loop and is useful in determining the calculated current value for test equipment.  

The test methods provided in BS EN 61000-4-39 helps in to assess immunity of an equipment or system against a defined phenomenon in the respective frequency range.  You can choose the most appropriate test for suitable equipment or systems depending on the EUT, frequency range, disturbance source, etc. to  produce better quality electronic devices.
