This Standard specifies the limits and test method of radiated emissions of electric and magnetic field from electric vehicles over the frequency range of 9 kHz ~ 30 MHz, and the limits and test method of conducted emissions over the frequency range of 450 kHz ~ 30 MHz. Conducted emission measurements in this Standard are applicable only to battery-charging systems which utilize a switching frequency above 9 kHz, which are mounted on the vehicle, and of which the power is transferred by metallic conductors. Conducted emissions requirements apply only during charging of the batteries from AC power lines. Conducted and radiated emissions measurements of battery-charging systems that use an induction power coupling device are not covered by this Standard. Note: GB 14023 shall govern, in the case of measurement of electromagnetic disturbances over the frequency range of 30 MHz ~ 1, 000 MHz.A.1 Calibration method The equivalent capacitance substitution method uses a dummy antenna in place of the actual rod ... two procedures shall be used: (a) the network analyser, or (b) the signal generator and radio-noise meter method.
