Following is the requirements for EN 61000-6-4

Emission

Port	Frequency range	Limits	Basic Standard	Applicability note	Remarks
Enclosure	30-230 MHz	30 dB(猩/m) quasi peak, measured at 30 m distance	EN 55011	See Note 1	May be measured at 10 m distance using the limits increased by 10 dB if the provisions of EN 55011 are met
	230-1000 MHz	37 dB(猩/m) quasi peak, measured at 30 m distance
AC Mains	0.15-0.5 MHz	79 dB(猩) quasi peak 66 dB(猩) average	EN 55011	See Note 2 See Note 3	-
	0.5-5 MHz	73 dB(猩) quasi peak 60 dB(猩) average
	5-30 MHz	73 dB(猩) quasi peak 60 dB(猩) average

	NOTE 1: In situ measurements are excluded from this standard.
	NOTE 2: Impulse noise (clicks) which occurs less than 5 times per minute is not considered. For clicks appearing more often than 30 times per minute the limit apply. For clicks appearing between 5 and 30 times per minute, a relaxation of the limits is allowed of 20 log 30/N dB (where N is the number of clicks per minute). Criteria for separated clicks may be found in EN 55014.

NOTE 3: Applies only to apparatus operating at less than 1000 V_rmsAC.
