EMC测试

请教论坛里的安规高手们，不知在小家电类的产品EMC测试RE(Radiated Emission)与CE（Conducted Emission)）是否要同时满足？我看标准是可选择其一通过即可。

Normally, the household appliance is tested with EN55014-1+EN55014-2. All emision tests are defined in EN55014-1. However, the RE (Radiated Emission) is only applicable to the Toys. For the household appliance, the RE test is not necessary.

Appliances are deemed to comply in the frequency range from 300 MHz to 1 000 MHz if
both of the following conditions ( 1) and 2)) are fulfilled:
1) all emission readings from the equipment under test shall be lower than the applicable
limits (Table 2a) reduced by the margin (Table 2b);
2) the maximum clock frequency shall be less than 30 MHz.
If either of condition 1) or 2) is not fulfilled, radiated measurements in the frequency range
from 300 MHz to 1 000 MHz shall be conducted and the limits of Table 3 for that range
applied. In any case the limits of Table 2a in the frequency range 30 MHz to 300 MHz
shall be met.
Table 2b – Margin when performing disturbance power measurement  in the frequency range 30 MHz to 300 MHz
Frequency range Quasi-peak dB (pW)
200 to 300 0 to          10 dB -
当功率骚扰（DP）200到300MHzQP余量小于10dB时，辐射（RE）是需要测试的。参见CISPR14-1 2009

如果是DC供电，做RE就可了
