Electromagnetic Compatibility (EMC) Directive

The EMC Directive and electromagnetic compatibility testing

Electromagnetic compatibility (EMC) testing assesses the interaction of electrical and electronic equipment or products with their environment and with other equipment or systems. If electrical devices or technologies are interconnected or located close to each other, they influence. To ensure that the equipment or systems do not generate electromagnetic interference or have their function impaired by such interference, the Electromagnetic Compatibility (EMC) Directive 2014/30/EU sets out rules for manufacturers and distributors of electrical and electronic equipment or complex machinery in the EU.

Why product conformity is essential for market introduction

Importers, manufacturers and distributors must demonstrate the conformity of their product as a prerequisite for introducing the product into the market. Placing a product on the market that does not comply with the rules carries a risk of sanctions: Distribution may be prohibited, or there may be problems with customs. In addition to the EMC Directive as the most crucial European regulation, there is also the Low Voltage Directive 2014/35/EU or the Radio Equipment Directive 2014/53/EU to be observed by manufacturers and product dealers of electrical and electronic equipment. All regulations are intended to guarantee the function of the devices and systems.

For this purpose, EMC testing is intended to ensure that equipment and installations are compatible as soon as they are placed on the market and put into operation. Compatibility exists if the products do not interfere with other equipment or radio and telecommunications traffic through electromagnetic emissions (interference emission) when used as intended. Similarly, according to the EMC Directive, electrical and electronic products must not themselves cause interference. An electromagnetic compatibility test can determine their immunity to interference, and electrostatic discharge (ESD) can be resolved with an electromagnetic compatibility test.

For which products is an electromagnetic compatibility test necessary?


The regulations of the EMC Directive differ depending on the area of application of the devices, products or installations. For consumer electronics, for example, different rules apply to devices used in aviation. Additional regulations also apply in the medical sector or the automotive industry, such as ECE Regulation No. 10 for motor vehicle EMC or the Medical Devices Directive. Accordingly, different tests and test standards come into question. In general, immunity tests (SF) and emission measurements (SA) are tested within the scope of EMC tests. In addition, there are tests of electromagnetic fields (EMF) or radio tests, which are carried out in the laboratory or the operating environment.

Testing can already take place during the development of a product, but at the latest, before it is placed on the market. The variety of products to be tested is huge. Here are some examples:

  • Multimedia devices: amplifier, loudspeaker, camera
  • Household appliances: blender, coffee maker, dishwasher, microwave oven, refrigerator
  • Lighting: LED displays (TV, monitor), floodlights, streetlights
  • E-mobility: e-bike and e-scooter
  • Tools: drill, circular saw, lawnmower
  • Medical technology: pacemakers, MRT, EEG, laboratory equipment
  • Others: lithium batteries, AC adapters, electric motors, doors, IT systems
