Describes limits and methods of measurement of radio disturbance characteristics for in-home communication apparatus that uses the low voltage power installation as the transmission medium. Applicable to equipment that transmits in the frequency range 1,7 MHz to 30 MHz. Procedures are given for the measurement of signals generated by the equipment and limits are specified for the frequency range 9 kHz to 400 GHz. No measurements need be performed at frequencies where no limits are specified. Aims to establish uniform requirements for the radio disturbance level of the equipment contained in the scope, to establish limits of disturbance, to describe methods of measurement and to standardize operating conditions and interpretation of results.
