Electromagnetic compatibility problems were not known before 1940. It was first noticed after the strange events that took place during the Second World War and which were not understood first. After these investigations, it was understood that these events were caused by electromagnetic waves emitted by communication systems and flight systems of aircraft. In those years, electronic systems were used more widely for military purposes. The first electromagnetic interference and electromagnetic compatibility standards have started to emerge with the improvements made in these systems.
However, by the time of 1980, electromagnetic compatibility problems still persisted. So much so that England lost a destroyer in the Falklands war. Since the communication systems and missile detection systems on the carrier affected each other negatively, the UK had to deactivate the missile detection system during communication. At that time, a missile from the opposite side hit the unprotected destroyer.
Electromagnetic interference and electromagnetic compatibility have been addressed more precisely, and the Electromagnetic Compatibility Directive 89 / 336 / EEC has been published in European Union countries and conditions and criteria for electromagnetic compatibility tests have been established. This directive was replaced by the Electromagnetic Compatibility Directive 2014 / 2014 / EU, which was subsequently published in 30. These directives cover all electrical and electronic devices that affect other electrical or electronic devices due to electromagnetic waves generated during operation, or are affected by the operation of other devices in this way.
In our country, these directives have been adapted to our own domestic law within the scope of European Union harmonization studies. Today in 2016, the Electromagnetic Compatibility Directive (2014 / 30 / EU) issued by the Ministry of Science, Industry and Technology is in force. With this regulation, electromagnetic compatibility of various electrical and electronic devices or systems has been regulated on the one hand and the principles of placing such devices and systems on the market have been determined.
In the Regulation, the basic requirements of electrical and electronic devices, the criteria for placing on the market, free movement conditions, the suitability of the equipment, conformity assessment bodies, market surveillance and control of equipment and protection measures.
Furthermore, the annexes to the regulation contain basic requirements, internal control of production (Module A), EU type examination (Module B), type compliance based on internal control of production (Module C) and EU declaration of conformity.
