EMC Electromagnetic Compatibility (EMC) is in accordance with the provisions of the Electromagnetic Compatibility Regulation (89 / 336 / EC). This regulation is based on the EMC Directive 89 / 336 / EEC issued by the European Union. This test can be carried out on all electrical and electronic devices that may interfere with other devices or may be affected by other devices. Electromagnetic Compatibility directive sets out the requirements to be applied in this regard.

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.

Electrical, electronic or electromechanical vehicles produce some electromagnetic energy around the same time they work. Electromagnetic interference is called electromagnetic interference. Electromagnetic Compatibility is that a device or system continues to operate in an electromagnetic environment without causing an energy interaction. For example, when transmitting voice or data with a mobile phone, the effect of the flight system of an aircraft in the same environment is an electromagnetic effect.

A large number of daily life electronic device Electromagnetic Compatibility has become increasingly desirable. It is necessary to intervene during production and to prevent electromagnetic disturbance of products in automotive, railway, aviation, medical devices and various other sectors. EMC tests is a series of successive tests and demonstrates the compatibility of products with each other.

Examples of major EMC tests are:

  • Propagation tests (Transmissive transmission, electric field, radiation diffusion, harmonic and flicker)
  • Immunity tests (Electrostatic discharge, Radiation radio frequency electromagnetic field, Explosion, rapid transient voltage peaks, Surge, high energy slow voltage peaks, Conductive disturbances caused by radio frequency fields, Power frequency magnetic fields, Voltage drops, interruptions and changes)
  • Broadcast monitoring test

The purpose of the tests is to see that the maximum electromagnetic disturbance generated by the device does not interfere with the use of designated devices. Product groups undergoing EMC testing are as follows:

  • Industrial production equipment

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.

How to Perform an EMC Test

  1. Electromagnetic noise emitted by cables or air around devices or electronic systems Emission EMC tests,
  2. Immunity EMC tests, which control the extent to which electromagnetic noise from devices or electronic systems is affected.

The TÜRCERT certification body also provides technical analysis and laboratory services to companies in need of certification. In this context, you can rely on the TÜRCERT certification organization, which has an experienced and expert staff in the EMC Electromagnetic Compatibility Test and other similar test studies.

Radiated Emission Tests - EMC Test

. Radiated Emission Test “is applied to determine the electromagnetic pollution level that a device emits through radio frequency.

Electric field and magnetic field values ​​are measured in emission test operations by radiation. In the measurements performed here, electric field antennas or ring antennas are used as the method. Bikonic antennas (30 - 300 MHz), Log - periodic antennas (300 - 200 MHz) or Funnel antennas (2.000 - 18.000 MHz) can also be used for this type of measurement. All these measurements can be made much easier using EMI Receiver. In addition to all these, it is possible to use the electric field probe to measure the high areas.
