Tables
1 Limits of mains terminal interference voltage in the
    frequency range 0.15 MHz to 30 MHz to 1000MHz at a
    distance of 10 m
2 Limits of radiated interference field strength in the
    frequency range 30 MHz to 1000 MHz at a test distance
    of 10 m
3 Limits of disturbance

Applicable to electrical equipment using signals in the frequency range 3 - 525 kHz for transmitting of information on low- voltage electrical installations, on the customer's premises or on the public supply system. Defines frequency bands allocated to different applications if appropriate, limits for their terminal output voltage in the operating band and limits for conducted and radiated disturbance. In addition, it provides measurement methods.
