Scope

This Part of GB/T 31983 specifies the frequency band classification for different
applications, the output level limit in the available frequency band, the conducted and
radiated disturbance limit; and gives the measurement method.
This Part does not specify signal modulation methods, coding methods or functional
characteristics, nor does it include environmental requirements and tests.
This Part is applicable to electrical equipment that uses signals in the frequency range
of 3kHz ~ 500kHz for information transmission on low-voltage power distribution
systems or on user-side power devices.
