37 Foreword

38 This document (prEN 50561-3:2014) has been prepared by Technical Committee CLC/TC 210,39 "Electromagnetic compatibility (EMC)".

40 This document is currently submitted for CENELEC enquiry.

41 This European Standard has been prepared under a mandate given to CENELEC by the European42 Commission and the European Free Trade Association and covers essential requirements of EN43 Directive(s).

44 For the relationship with EU Directive(s) see informative Annex ZZ, which is an integral part of this45 document.

46 Annex ZZ will be provided at a later stage.

47 The scope is extended to the whole radio-frequency range from 9 kHz to 400 GHz, but limits are formulated48 only in restricted frequency bands, which are considered sufficient to reach adequate emission levels to49 protect radio broadcast and telecommunication services and to allow other apparatus to operate as intended50 at reasonable distance.

54 1 Scope

55 This part of EN 50561 specifies limits and methods of measurement of radio disturbance characteristics for56 in-home communication apparatus that use the low voltage power installation as the transmission medium.57 This part of EN50561 applies to equipment that uses frequencies including those above 30MHz in order to58 communicate.5960 Equipment communicating exclusively in the frequency range from 1,6065 MHz to 30 MHz is covered in EN61 50561-1.6263 The requirements specified in this document are applicable for apparatus using frequencies of transmission64 up to 87.5 MHz.6566 NOTE: a signal level mask will ensure sufficient decay to adequately protect the reception of radio services (see figure67 1).6869 Procedures are given for the measurement of signals generated by the equipment and limits are specified for70 the frequency range 9 kHz to 400 GHz. No measurement is required at frequencies where no limits are71 specified.
