Tests of electromagnetic compatibility – EMC

Electromagnetic compatibility means the ability of an electrical device to avoid interference with other electrical devices and to resist interference from them. The emission of electromagnetic radiation is a common characteristic of all electrical devices; it must not however exceed the permitted level.

Every electrical device can be subjected to tests of electromagnetic compatibility in accordance with the entire standard or in accordance with its individual articles. These tests are not only an integral part of the development of new products, but are also absolutely essential when a new product is introduced to the market.

We offer tests of electromagnetic compatibility in accordance with Czech and international technical standards or in accordance with the client’s technical requirements. Test reports can be used as the basis for the preparation of the EU Declaration of conformity as well as an EU Declaration.

The EMC laboratory offers the following tests:

  • Measurement of conducted interference in the bandwidth 9 kHz to 130 MHz in various types of artificial networks, including the measurement of motor vehicle accessories.
  • Tests of resistance to groups of transient impulses.
  • Measurement of radiated interference in the bandwidth 9 kHz to 18 GHz.
  • Tests of resistance to a surge wave.
  • Measurement of radiated power in the bandwidth 30 to 1000 MHz.
  • Tests of resistance to conducted high frequency interference.
  • Frequency analysis in the bandwidth 2 Hz to 22.5 GHz./li>
  • Tests of resistance to high frequency electromagnetic fields with various types of modulation.
  • Measurement of effects on the network (harmonic, flicker).
  • Tests of resistance to fluctuation and outages of supply voltage.
  • Measurement of magnetic fields
  • Tests of resistance to magnetic fields.
  • Tests of resistance to static electricity discharge.
  • Tests of resistance to magnetic field pulses.
