IEC 62311:2019适用于没有关于人体暴露于电磁场的专用产品标准或产品系列标准适用的电子和电气设备。它涵盖了带有有意或无意散热器的设备及其组合。 本文件提供了评估方法和标准，用于根据与电场、磁场和电磁场相关的人员暴露限制来评估设备。覆盖的频率范围从0 Hz到300 GHz。 这第二版取消并取代了2007年出版的第一版。本版构成技术修订版。 本文件未规定通过基本限制和/或参考水平表示的限度。此类限制取决于所应用的评估方案，例如通过区域限制。与上一版相比，此版本包括以下重大技术变更: a)引入了有意和无意辐射器之间的明确区别； b)考虑暴露于非均匀场； c)改进了评估程序不确定性的处理； d)附件A中描述了各种求和方案； e)已使用同时发布的基本标准中的信息，因此已删除上一版本的所有信息附件。 关键词:人体暴露、电磁场（0 Hz至300 GHz）。

IEC 62311:2019 applies to electronic and electrical equipment for which no dedicated product standard or product family standard regarding human exposure to electromagnetic fields applies. It covers equipment with intentional or non-intentional radiators as well as a combination thereof.
This document provides assessment methods and criteria to evaluate equipment against limits on exposure of people related to electric, magnetic and electromagnetic fields. The frequency range covered is from 0 Hz to 300 GHz.
This second edition cancels and replaces the first edition published in 2007. This edition constitutes a technical revision.
This document does not specify limits expressed by means of basic restrictions and/or reference levels. Such limits are subject to the applied assessment scheme, for example by means of regional limits.
This edition includes the following significant technical changes with respect to the previous edition:
a) a clear distinction between intentional and unintentional radiators has been introduced;
b) the exposure to non-uniform fields is considered;
c) the treatment of uncertainty for the assessment procedures has been improved;
d) various summation regimes are described in Annex A;
e) the information from meanwhile published basic standards has been used and hence all informative annexes of the previous edition have been removed.
Key words: Human Exposure, Electromagnetic Fields (0 Hz to 300 GHz).
