BS EN 55103-2:2009

What is this BS EN 55103-2 - EMC immunity about?  

BS EN 55103-2 discusses electromagnetic compatibility and product family standard for audio, video, audio-visual, and entertainment lighting control apparatus for professional use with a focus on immunity. BS EN 55103-2 is the second part of the BS EN 55103 multi-series on electromagnetic compatibility for EMC immunity requirements that apply to professional audio, video, audiovisual, and entertainment lighting control apparatus as defined in BS EN 55103-2 intended for use in the environments.  

BS EN 55103-2 includes the digital apparatus and sub-assemblies. Disturbances in the frequency range 0 Hz to 400 GHz are covered, but requirements are not established over the whole of that range. 

BS EN 55103-2 does not apply to: 

• Consumer apparatus 
• Apparatus specifically designed for security systems 
• Apparatus designed to radiate electromagnetic energy for radio communications purposes 

Who is BS EN 55103-2 - EMC immunity for? 

BS EN 55103-2 on EMC immunity is useful for: 

• Audio and video device manufacturers  
• Audio programmers  
• Music producers 
• Sound technicians 
• Common control interface developers   

Why should you use BS EN 55103-2 - EMC immunity?  

BS EN 55103-2 defines two test methods required to test the low-frequency common-mode immunity performance of various types of balanced signal and control ports. The purpose of these test methods is to measure the immunity to specific test signals, not to measure the common-mode rejection ratio which is specified in functional standards 

The objective of BS EN 55103-2 is to define the immunity test requirements, test signals, performance criteria, and test methods for apparatus, in relation to electromagnetic immunity to continuous and transient conducted and radiated electromagnetic disturbances including electrostatic discharges. These test requirements represent essential electromagnetic compatibility requirements.
