Defines limits and methods of measurement of radio disturbance characteristics for in-home communication apparatus that use the low voltage power installation as the transmission medium.

This part of EN50561 specifies limits and methods of measurement of radio disturbance characteristics for in-home communication apparatus that use the low voltage power installation as the transmission medium. This part of EN50561 applies to equipment that uses frequencies including those above 30MHz in order to communicate. Procedures are given for the measurement of signals generated by the equipment and limits are specified within the frequency range 9kHz to 400GHz. No measurement is required at frequencies where no limits are specified. The radiated emission requirements in this standard are not intended to be applicable to the intentional transmissions from a radio-transmitter as defined by the ITU, nor to any spurious emissions related to these intentional transmissions. NOTE The requirements defined in this standard effectively restrict the intended transmission frequencies to below 87,5MHz.
