电磁兼容性(EMC).第4-2部分:试验和测量技术.静电放电抗扰试验

[中文适用范围]： 本部分 IEC 61000 涉及受静电放电（直接来自操作人员，以及来自人员到邻近物体）影响的电气和电子设备的抗扰度要求和测试方法。它还定义了与不同环境和安装条件相关的测试电平范围，并建立了测试程序。本标准的目的是为评估电气和电子设备在遭受静电放电时的性能建立一个共同且可重复的基础。此外，它还包括可能从人员到关键设备附近物体发生的静电放电。本标准定义了：- 放电电流的典型波形；- 测试电平范围；- 测试设备；- 测试设置；- 测试程序；- 校准程序；- 测量不确定度。本标准给出了在“实验室”进行的测试和在最终安装现场进行的“安装后测试”的规范。本标准无意规定适用于特定设备或系统的测试。其主要目的是为所有相关的 IEC 产品委员会提供一般基本参考。产品委员会（或设备用户和制造商）仍负责为其设备选择合适的测试和严重程度等级。为了不阻碍协调和标准化工作，强烈建议产品委员会或用户和制造商（在其未来的工作或旧标准的修订中）考虑采用本标准中规定的相关抗扰度测试。 [外文原描述]： IEC 61000-4-2:2008 relates to the immunity requirements and test methods for electrical and electronic equipment subjected to static electricity discharges, from operators directly, and from personnel to adjacent objects. It additionally defines ranges of test levels which relate to different environmental and installation conditions and establishes test procedures. The object of IEC 61000-4-2:2008 is to establish a common and reproducible basis for evaluating the performance of electrical and electronic equipment when subjected to electrostatic discharges. In addition, it includes electrostatic discharges which may occur frompersonnel to objects near vital equipment. IEC 61000-4-2:2008 defines typical waveform of the discharge current, range of test levels, test equipment, test setup, test procedure, calibration procedure and measurement uncertainty. IEC 61000-4-2:2008 gives specifications for test performed in ;laboratories; and ;post-installation tests; performed on equipment in the final installation. This second edition cancels and replaces the first edition published in 1995, its amendment 1 (1998) and its amendment 2 (2000) and constitutes a technical revision. It has the status of a basic EMC publication in accordance with IEC Guide 107. The main changes with respect to the first edition of this standard and its amendments are the following: - the specifications of the target have been extended up to 4 GHz. An example of target matching these requirements is also provided; - information on radiated fields from human-metal discharge and from ESD generators is provided; - measurement uncertainty considerations with examples of uncertainty budgets are given too.
