Purpose: The purpose of this document is to present guidelines for the Electromagnetic Compatibility (EMC) design of electronic devices. The focus is to sharpen the awareness of EMI at an early stage of the development. This is reasonable because early planning of the EMC of a system has several advantages. Above all, the probability of a "first-time-right" development increases (the risk that a later redesign will be necessary is reduced). Additionally, an early EMC planning helps to decrease the costs for development and testing.

If the EMC of a system is considered ex post facto may be inevitable to take measures that can only reduce the effects of EMI but not eliminate the root causes. Such measures can include additional shielding, which is connected with a high system weight. The well-planned design can eliminate the origin of problems, often with simple measures.

This document also aims at clear identification of EMC design means for reference in an EMC-control plan.
