All electrical or electronic or electromechanical vehicles emit some electromagnetic energy. Electromagnetic Compatibility (EMC) is the continuation of a device or system in an electromagnetic environment without interference and interference.
In other words, it can be defined as the fact that the device or system does not affect other devices or systems while they are operating and is not affected by their operation. To illustrate the problem of electromagnetic interference, it is an electromagnetic interference problem when an aircraft in the same environment interferes with the navigation system while performing the task of a mobile phone, that is, providing voice or data communication.
In this problem, the source is mobile phone, the coupling path is air, and the affected system is the airplane navigation system. The operation of a television and a drill connected to the same energy network line is an example of interference through conductivity. In this problem, the source drill uses the power line, the cable as the coupling path and creates interference and distortion on the TV screen in the affected system state. If the devices in these two interference examples do not interfere with each other while operating, electromagnetic compatibility can be mentioned.
EMC standards have been developed for two purposes. First, they regulate the electromagnetic emission from a device, then they ensure the immunity of this device to electromagnetic interference.
The EMC test aims to determine the performance degradation, deterioration and the relation of the devices with these effects as a result of electromagnetic waves emitted by electrical and electronic devices during operation.
Electromagnetic compatibility has become a much more sensitive topic. From military fields to space technologies, from medicine to industrial applications or to the automotive industry, every segment has to comply with EMC requirements. There are many national and international civil and military standards to provide EMC.
These standards basically describe the levels of the electromagnetic energy emitted by the system (or device) to the environment or the energy that is affected by the environment.
The main EMC tests are Emission tests, Immunity tests and Diffusion monitoring tests. The purpose of the tests is to see that the maximum electromagnetic disturbance created by the device will not prevent the use of the specified devices.

Electromagnetic Compability (EMC); it is intended to operate any electronic system or device without affecting or affecting other systems and devices in the environment.
Electrical and electronic devices should not affect the functions or performances of other devices produced by their electromagnetic noise or impacts during operation. These two basic requirements are complementary elements and devices must satisfy both basic requirements.
EMC compliance testing is a mandatory requirement in most markets, including Europe, the US, China, Korea, Australia and New Zealand. EMC testing is required to help meet regulatory requirements, improve product performance and reduce costly non-compliance risks. Third-party EMC tests and conformity assessments also help to strengthen the competitive position in the market.
