What is BS EN 55014-1 - Electromagnetic compatibility testing about?
BS EN 55014-1 is the first part of the BS EN 55014 series of standards that focuses on electromagnetic compatibility. BS EN 55014-1 specifies the requirements that apply to the emission of radio-frequency disturbances in the frequency range 9 kHz to 400 GHz from appliances, electric tools and similar apparatus as defined below, whether powered by AC or DC. BS EN 55014-1 specifies the requirements that apply to the emission of radiofrequency disturbances in the frequency range 9 kHz to 400 GHz from appliances, electric tools, and similar apparatus. 
Note: Excluded from the scope of BS EN 55014-1 are the equipment for which all emission requirements in the radio-frequency range are explicitly formulated in other CISPR standards and the equipment intended to be used only on a vehicle, ship or aircraft. 
Who is BS EN 55014-1 - Electromagnetic compatibility testing for?
BS EN 55014-1 on electromagnetic compatibility requirement applies to:
- Household or similar appliances manufacturers and importers  
- Test laboratories 
- Design engineers of the appliance industry 
- Distributors and retailers of household appliances and electric tools 
Why should you use BS EN 55014-1 - Electromagnetic compatibility testing?
BS EN 55014-1 provides electromagnetic compatibility (EMC) testing during the product design will help minimize the possibility that radiated or conducted emissions produced by your device will interfere with other electronic products in its vicinity.
What’s changed since the last update?  
BS EN 55014-1:2017 supersedes BS EN 55014-1:2006, which is withdrawn. 
In comparison with the previous edition, the following technical modifications have been made: 
- Improvements to the operating conditions for testing induction cooking appliances and incorporation of the limits for these appliances in the body of the standard 
- Addition of general and specific test setups (e.g. vacuum cleaners and robotic cleaners) for radiated emission  
- Provision for the current probe test method for conducted disturbance measurements on ports other than the AC mains port in alternative to the voltage probe method 
- Clarifications about click analysis (e.g. measurements under the presence of continuous disturbances). and the measurement of equipment with built-in luminaries 
- Introduction of testing on wired network ports of household equipment
