GB/T 17626.4-2008 in English

《GB/T 17626.4-2008电磁兼容 试验和测量技术 电快速瞬变脉冲群抗扰度试验》由TC246（全国电磁兼容标准化技术委员会）归口，TC246SC1（全国电磁兼容标准化技术委员会高频现象分会）执行，主管部门为国家标准化管理委员会。
GB/T17626的本部分涉及电气和电子设备对重复性电快速瞬变的抗扰度要求和试验方法。此外,还规定了试验等级的范围,确定了试验程序。
本部分的目的是为评估电气和电子设备的供电电源端口、信号、控制和接地端口在受到电快速瞬变(脉冲群)干扰时的性能确定一个共同的能再现的评定依据。本部分规定的试验方法描述了一种评估设备或系统对已定义现象抗扰度的一致性方法。
注:本部分是全国电磁兼容标准化技术委员会的电磁兼容基础标准的一部分,专业标准化技术委员会负责确定本
抗扰度试验标准部分是否适用。如果适用,专业标准化技术委员会负责确定适当的试验等级和性能判据。负责本部分的标准化技术委员会愿意与专业标准化技术委员会在其产品特殊的抗扰度试验值评估方面合作。
本部分规定了下列几项:
---试验电压波形;
---试验等级的范围;
---试验设备;
---试验设备的校验程序;
---试验配置;
---试验程序。
本部分给出了在实验室试验和安装后试验的技术规范。

1 Scope

This Part of GB/T 17626 relates to the immunity of electrical and electronic equipment to repetitive electrical fast transients. It gives immunity requirements and test procedures related to electrical fast transients/bursts. It additionally defines ranges of test levels and establishes test procedures.
The object of this standard is to establish a common and reproducible reference for evaluating the immunity of electrical and electronic equipment when subjected to electrical fast transient/bursts on supply, signal, control and earth ports. The test method documented in this Part of IEC 61000-4 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon.
Note: As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC.
As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard should be applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria. TC 77 and its sub-committees are prepared to co-operate with product committees in the evaluation of the value of particular immunity tests for their products.
The standard defines:
——test voltage waveform;
——range of test levels;
——test equipment;
——verification procedures of test equipment;
——test set-up;
——test procedure.
The standard gives specifications for laboratory and post-installation tests.
