电磁兼容性（EMC）-第4-4部分：测试和测量技术-电气快速瞬变/突发抗扰度测试

Electromagnetic compatibility (EMC) - Part 4-4: Testing and measurement techniques - Electrical fast transient/burst immunity test

IEC 61000-4-4：2012 涉及电气和电子设备对重复电气快速瞬变的免疫力。它提供与电气快速瞬变/突发相关的抗扰度要求和测试程序。它还定义了测试级别的范围，并建立了测试过程。本标准的目的是建立一个通用的、可重复的参考，以评估电气和电子设备在电源、信号、控制和接地端口上受到电气快速瞬态/突发时的抗扰度。本标准中记录的测试方法描述了评估设备或系统对已定义现象的免疫力的一致方法。

测试等级

EFT test levels (IEC/EN 61000-4-4)
Power ports, earth ports (PE)
Level	Voltage peak (kV)	Repetition frequency (kHz)
1	.5 kV	5 or 100 kHz
2	1 kV	5 or 100 kHz
3	2 kV	5 or 100 kHz
4	4 kV	5 or 100 kHz
x	special	special
x can be any level specified in product specific standards

电快速脉冲群波形包络

脉冲群特征

• 300 ms 一个脉冲群周期
• 5 kHz 意味着脉冲周期就是0.2 ms为单个脉冲周期，当5 kHz时那么15 ms群脉冲，即15 ms/0.2 ms就是75个脉冲。
• 100 kHz 意味着脉冲周期就是0.01 ms为单个脉冲周期，当100 kHz时那么0.75 ms群脉冲，即0.75 ms/0.01 ms就是75个脉冲。

Note： (1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative references is the list of the published standard.

In the case of undated standard, a link to the last dated version is provided.

In the case of series, a link to each standard identified in the series is provided.

We also invite you to check (via the website) whether corrigenda and/or amendments shall be read in conjunction with the main standard.

(7) Estimated dates to be confirmed at the publication of the standards.
