[中文适用范围]： 电磁兼容性 (EMC) - 第 2-5 部分：环境 - 电磁环境的描述和分类。了解拟运行的电气和电子设备所在地点存在的电磁环境是实现电磁兼容性的必要前提。本文件介绍了干扰程度的概念并定义了各种电磁现象的干扰程度；通过属性对各类场所进行分类和描述；提供了可能存在于环境中的不同电磁现象的背景信息；编制了被认为是与这些场所类别相关的电磁现象的兼容电平表。本文件旨在为负责考虑和制定抗扰度要求的人员提供指导，并为选择抗扰度电平提供基本指导。数据适用于在本文档中考虑的任何场所中运行的任何电气或电子设备、子系统或系统。 [外文原描述]： IEC/TR 61000-2-5:2017(E) is a Technical Report intended for guidance for those who are in charge of considering and developing immunity requirements. It also gives basic guidance for the selection of immunity levels. The data are applicable to any item of electrical or electronic equipment, sub-system or system that operates in one of the locations as considered in this document. This Technical Report provides the following: – introduces the concept of disturbance degrees and defines these for each electromagnetic phenomena; – classifies into various location classes and describes them by means of attributes; – provides background information on the different electromagnetic phenomena that may exist within the environment and; – compiles tables of compatibility levels for electromagnetic phenomena that are considered to be relevant for those location classes. This third edition cancels and replaces the second published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the description of the radiated electromagnetic environment has been updated taking into account recent communication technologies; b) some conducted phenomena and respective interference sources have been described in more detail.
