An Introduction to EMC Compliance

Electromagnetic Compatibility (EMC) is a branch of electrical engineering that studies the unintentional generation, propagation and reception of electromagnetic energy with reference to the unwanted effects or Electromagnetic Interference (EMI).

The EMC Directive governs how EMC is managed and applies to all electronic or electrical products liable to cause or be disturbed by an electromagnetism.

Almost all manufacturers in the electronics or electrical industries have to ensure their products are compliant with the requirements of the Directive and are able to demonstrate that this is the case in order to affix a valid CE Marking to them.

The aim of EMC is to ensure correct operation, in the same electromagnetic environment, of a number of different pieces equipment which use electromagnetic phenomena, and the avoidance of any interference with each other.
