如题，可以拿一款产品举倒说明，最好全面点。
现在只是想了解了解。期待解答！

就我所知道的有下列幾項：

CE/RE EN550-14家電及手工具產品

IEC 1000-4-2 ESD靜電放電

IEC 1000-4-3輻射耐受性

IEC1000-4-4快速暫態與叢訊

IEC1000-4-5雷擊突波耐受性

IEC 1000-4-6傳導耐受性

IEC 1000-4-8電源頻率磁場

IEC 1000-4-11瞬降瞬斷電壓

EN61000-3-2電流諧波

EN61000-3-3電壓變動與閃爍

家电产品测试EMC
那一定要做的就是EMI:传导,和功率辐射,谐波,電壓變動與閃爍
EMS:这块有的不要做,有的要做,这里有四类
4.1 Category I: apparatus containing no electronic control circuitry, for example motor operated appliances,
toys, tools, heating appliances and similar electric apparatus (such as UV and IR radiators).
Electric circuits consisting of passive components (such as radio interference suppression capacitors or
inductors, mains transformers and mains frequency rectifiers) are not considered to be electronic control
circuitry.
Examples: apparatus containing components such as electromotors, electromechanical switches,
thermostats, (rechargeable) batteries.
4.2 Category II: mains powered motor operated appliances, tools, heating appliances and similar electric
apparatus (for example — UV radiators, IR radiators and microwave ovens) containing electronic control
circuitry with no internal clock frequency or oscillator frequency higher than 15 MHz.
NOTE The value 15 MHz is tentative and may be modified after a period of experience.
4.3 Category III: battery powered apparatus (with built-in batteries or external batteries), which in normal
use is not connected to the mains, containing an electronic control circuitry with no internal clock frequency
or oscillator frequency higher than 15 MHz.
This category includes apparatus provided with rechargeable batteries which can be charged by connecting
the apparatus to the mains power. However, this apparatus shall also be tested as an apparatus in
category II while it is connected to the mains network.
4.4 Category IV: all other apparatus covered by the scope of this standard.

对应要做的项目
7.2.1 Category I
Category I apparatus is deemed to fulfil the relevant immunity requirements without testing.
7.2.2 Category II
Category II apparatus shall fulfil the following requirements:
Functions (non-exhaustive)
Criteria
A Bb C1c C2c
Motor speed
Torque
Movement
Power (consumption, input)
Switching (change of state)
Heating
Timing (programme, delay, duty cycle)
Stand-by
Data storage
Sensor functions (signal transmission)
Indicators (visual and acoustic)
Audio function
Illumination

a Values are exclusive of the measurement accuracy.
b For criterion B, measurement or verification is performed during the stable operations of the Equipment Under Test before and
after the application of the specified phenomenon.
c For criterion C, distinction is made between
C1: before resetting and
C2: after resetting.
d Switching-off is allowed, switching-on is not allowed.
e Loss or change of data is allowed.
f Lower performance as specified by the manufacturer is allowed, but no loss of correct function.
g Loss of correct functions allowed.

一般要做十项，ＥＭＩ五项，ＥＭＳ五项

EMI應該只有四項測試才對~

关于标准EN 55014上归类的家电，自己再补充以下，

对于带有自动控制（比如程序如洗衣机，空调等等），还要做喀呖声测试

也属于EMI的范畴
