Electromagnetic compatibility - is the ability of electrical and electronic devices, plants, and systems to operate in their electromagnetic environment without adverse effects and without disturbing other electrical devices with unwanted effects.
The electromagnetic compatibility of electronics is an important and necessary quality feature because unintentional interference in the operation of electronic devices can have unforeseeable consequences. The requirement for the electromagnetic compatibility of devices, vehicles, etc. is therefore subject to statutory regulations in the European Union and in many other markets.
