EMC Tests for Electrical Devices

Electromagnetic compatibility tests (EMC tests or EMC tests) are carried out to prove that electrical or electronic devices do not disturb or interfere with the electromagnetic waves they emit or operate without being affected by other devices. These tests are based on the requirements applicable to all electrical and electronic devices and systems.

With the EMC tests performed, manufacturers prove that their products meet EMC criteria. EMC standards have been mandatory for all electrical and electronic devices since 1996. Companies wishing to offer their products not only to the European Union countries but to all the world markets are required to have the necessary EMC tests and LVD tests and put the CE mark on the devices passing these tests.

The 2014 / 30 / EU directive applicable in European Union countries and the Electromagnetic Compatibility Directive (2016 / 2014 / EU) issued by the Ministry of Science, Industry and Technology on the basis of this directive in our country cover all electrical and electronic devices, systems and equipment.

In general, electromagnetic compatibility tests are applied to: industrial production equipment, household appliances and household appliances, radio receivers and television receivers, mobile radio and mobile radio or commercial radio telephone equipment, air radio and marine radio (radio) equipment, telecommunications networks, mobile radio equipment, broadcast transmitters, electronic training tools, lamps and fluorescent lamps.

There are two commonly used concepts in electromagnetic wave propagation of electrical devices: the source device and the victim device. All electrical devices that produce electromagnetic waves that cause an electromagnetic interference are defined as welding devices. Devices that are exposed to and affected by electromagnetic waves emitted by the source device are also defined as victims.

An electrical or electronic device can be affected by other devices in the same environment, but may also cause interference to them. That is, an electrical or electronic device can be both a source device and a victim device.

In addition, the concept of coupling is widely used in electromagnetic compatibility. Coupling describes the ways in which electromagnetic interference is used to access an electrical or electronic device or system. There are two ways in general. Spatial radiation (radiated) is aerial transportation. Electrical conduction is a physical conductivity path, such as conducted cable.
