Electromagnetic Compatibility Tests Why?

Nowadays, electromagnetic compatibility tests are increasingly being demanded for a large number of electrical and electronic devices used in everyday life. First and foremost, manufacturers want to prove that their products are suitable for human health and customer satisfaction in order to ensure customer satisfaction, to retain their existing customers and to easily open to new markets. The necessity of recalling the products put on the market for various reasons places a great financial burden on the enterprises. There is also a loss of reputation, which is extremely difficult to compensate. This concerns not only the electricity and electronics sector, but also many other sectors such as the automotive sector, the transport sector, the medical devices sector and the military equipment sector.

Electromagnetic compatibility tests are carried out to determine the basic criteria to be applied to all electrical or electronic devices whose operation may be impaired or affected by other devices. EMC tests are actually a series of successive tests and the main purpose is to demonstrate the compatibility of these devices with each other in operation.

The main tests performed within the scope of electromagnetic compatibility tests are: electrostatic discharge (ESD) immunity, transmitted emissions, transmitted immune disorders, harmonic current emission, harmonics and immunity to intermediate harmonics, power interference, voltage fluctuation and vibration, overvoltage immunity, immunity to antenna input, power frequency magnetic field and vibration wave immunity.

Electromagnetic pollution in the environment is increasing day by day. As the speed increases in digital circuits, switching levels of integrated circuits decrease. However, the quality of any electrical or electronic product or system is directly related to their electromagnetic compatibility. Therefore, the need for electromagnetic compatibility tests is increasing day by day.

Today, the most tested and certified service groups by the testing and inspection organizations are: household electrical appliances, commercial electrical appliances, professional and industrial devices, lighting fixtures, medical devices and measuring and control devices.

During the testing of all these devices, it is very important to comply with the applicable regulations and standards. The ability of these devices to compete not only in the European Union market but also in the world markets depends on this.
