电动工具空间辐射限值要求？

wyjun121

  电动工具类在EN55014-1 功率辐射里有三种限值对应三种功率，空间辐射对电动工具没有分类限值，请问大于700W的电动工具在选择做空间辐射的时候用那个限值？

						Limit
Testing method			Standard	Frequency range MHz		dB V/m	Remark
						Quasi-peak
OATS a or SAC bd			CISPR 16-2-3	30  230		30	Measurement distance 10 m
				230 300		37
				300	1 000	37
FAR e			CISPR 16-2-3	30 – 230 –	230 1 000	42 to 35 f 42	Measurement distance 3 m
				30 –	230	30
TEM-Waveguidec			IEC 61000-4-20	230 –	1 000	37	–
NOTE		The lower limit is applicable at the transition frequency.
a	OATS = open area test site
b	SAC = semi-anechoic chamber
c	The TEM-waveguide is limited to devices without cables attached and with a maximum size according to subclause 6.1 of IEC 61000-4-20 (The largest dimension of the enclosure at 1 GHz measuring frequency is one wavelength, 300 mm at 1 GHz)
d	Measurements may be made at closer distance, down to 3 m. An inverse proportionality factor of 20 dB per decade shall be used to normalize the measured data to the specified distance for determining compliance.
e	FAR = fully anechoic room. All equipment, including floor-standing equipment, shall be measured within the test volume as described in Figure 6 of CISPR 16-2-3.
f	Decreasing linearly with the logarithm of the frequency.

你这只是把辐射的限值复制上去了，大于700W的电动工具也是用这个限值，那不是很难过？？？？？

空间辐射一般在30khz~1000khz
