The IEC 1000 or EN 61000 series of standards are planned as central EMC standards into which
all EMC regulations (e.g. IEC 801, IEC 555) are to be integrated in the next few years.

In order to be able to choose suitable interference suppression components, the way in which con-
ducted interference is propagated needs to be known
