EMC testing

Laboratory for Electromagnetic Compatibility is accredited by ATS and accepted in international CB scheme. The accreditation confirms the independence and competence of Laboratory in the provision of development and testing of products by using modern equipment according to requirements of standards and technical specifications.

Many years of experience in the field of electromagnetic compatibility enables Laboratory to offer:

  • pre-compliance testing
  • services of clarification of the requirements of the standards to the manufacturers, for development of new products
  • services of the final testing for CE marking

Tests are carried out according to the current versions of Serbian standards that are identical with the international versions.

Test reports issued by the Laboratory are accepted in EU countries and provide placement of your product on EU market.

Many years of experience in testing of electrical products provide fast and efficient services in a modern testing laboratory, with trained staff.

All tests (from the stage of development, analysis, pre-compliance, all the way to the final testing for the purpose CE marking) can be done efficiently and cost-effectively in one place.

Types of Testing

The legal framework for the requirements in terms of electromagnetic compatibility are Directives 2014/30 /EU and 2004/108/EC, and in the Republic of Serbia is Rulebook on electromagnetic compatibility.

Laboratory for EMC performs a complete service of the following tests:

  • EMC testing according to the requirements of basic, generic and standards for product groups
  • Testing of conducted electromagnetic interference (methods: artificial network AMN, impedance stabilization network for the ISN, voltage probes, current probes, intermittent interference)
  • Testing of electromagnetic Interference (loop antenna, semi-anechoic chamber, open area test site - OATS)
  • Limits for harmonic current emissions
  • Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems
  • Electrostatic discharge immunity test
  • Radiated, radio-frequency, electromagnetic field immunity test
  • Electrical fast transient/burst immunity test
  • Surge immunity test
  • Immunity to conducted disturbances, induced by radio-frequency fields
  • Power frequency magnetic field immunity test
  • Pulse magnetic field immunity test
  • Voltage dips, short interruptions and voltage variations immunity tests
  • Immunity tests for low frequency for harmonics and inter harmonics

The types of products that can be tested

Based on testing, it is possible to determine the compliance of devices or systems, such as:

  • information technology devices
  • industrial, scientific and medical devices
  • home appliances
  • electrical appliances
  • electric lamps

and similar devices.

Briefly about electromagnetic compatibility

Electromagnetic compatibility is the ability of a device or system to function satisfactorily in its electromagnetic environment, but at the same time does not cause impermissible electromagnetic interference to other devices or systems in that environment.

Objectives of electromagnetic compatibility tests are identifying:

  • emission levels
  • level of immunity of devices

Electromagnetic emission is the process by which the source, device or system, emits electromagnetic energy into the surrounding space by radiation or conduction, using cables.

Electromagnetic immunity is the ability of a device or system to operates without worsening its characteristics (or with the allowable degradation in the manner defined by standards for electromagnetic compatibility) in the presence of electromagnetic interference.
