标准摘要
[中文适用范围]： 本部分 IEC 61000 的目的是提出一种评估高海拔电磁脉冲 (HEMP) 和高功率电磁 (HPEM) 环境对电子系统影响的方 法。在此背景下，系统是指汇集在一起执行功能的子系统、设备和组件的集合（更完整的定义见 3.20）。将介绍与该方 法相关的技术及其优缺点，并提供示例说明如何应用这些技术来评估安装中电子系统的敏感性。这项工作与评估 EMC 系统 级敏感性密切相关。本技术规范的目的是提供有关评估 HEMP 和 HPEM 环境导致的系统级敏感性的可用方法的信息。将讨论 这些方法的优缺点，并提供示例说明应如何使用这些技术。典型系统具有外部连接，有线或无线，本规范包括对这些连接 的评估。本规范提供一般指导。它不涉及安全问题，也不与 ITU-T 关于保护电信设备的努力相冲突。 [外文原描述]： IEC/TS 61000-5-9:2009(E) is to present a methodology to assess the impact of High-altitude Electromagnetic Pulse (HEMP) and High Power Electromagnetic (HPEM) environments on electronic systems. In this context a system refers to a collection of sub-systems, equipment and components brought together to perform a function. The techniques associated with this methodology and their advantages and disadvantages will be presented along with examples of how the techniques can be applied to evaluate the susceptibility of electronic systems such as those found in installations. This work is closely related to the evaluation of EMC system level susceptibility. The purpose of IEC/TS 61000-5-9:2009 is to provide information on available methods for the assessment of system-level susceptibility as a result of HEMP and HPEM environments. The advantages and disadvantages of the methods will be discussed along with examples of how the techniques should be employed. Typical systems have external connections, wired or wireless, and the assessment of these are included within this specification. IEC/TS 61000-5-9:2009 gives general guidance. It does not cover safety issues nor does it conflict with ITU-T efforts concerning the protection of telecommunications equipment. IEC/TS 61000-5-9:2009 has the status of a basic EMC publication in accordance with IEC Guide 107.
