Electromagnetic Compatibility (EMC) is the ability of electrical or electronic devices to operate in harmony with their environment in their electromagnetic environment. Before each electrical, electronic or electromechanical device is put into user service, EMC tests must be performed to determine that it does not emit unwanted interference signals to its environment, the electrical power lines to which it is fed or the data transmission lines to which it is connected, and that it is not affected by its environment, the electrical power lines to which it is fed or the data transmission lines to which it is connected.

The Electromagnetic Laboratory has two semi-reflection-free rooms of different sizes and two screened rooms where accredited military and commercial EMC experiments can be performed. There is also a fully reflection-free room and an open field test area where the calibrations of the devices used in EMC experiments and electromagnetic pollution measurements are carried out.
