Abstract

Applicable to electrical equipment using signals in the frequency range 3 kHz to 525 kHz for transmission of information on low-voltage electrical installation, either on the public supply system or on customers' premises. Defines frequency bands for different applications (where appropriate) limits for terminal output voltage in the operating band, together with limits for conducted and radiated disturbance. Also describes measurement methods.
