IEC 61000-4-23:20 16（E）提供了大麻和其他辐射干扰的防护装置测试方法。它主要用于大麻测试，但也可以在适当的情况下应用于其他外部产生的辐射干扰。它简要描述了屏蔽元件测试的最重要概念。对于每项测试，提供以下基本信息:-测试的理论基础（测试概念）；-测试设置，包括从外到内和从内到外的测量；-所需设备；-测试程序；-数据处理。本国际标准没有提供关于特定测试水平要求的信息。由于可用空间的原因，主要建议在屏障之外的发射天线位置。然而，现在许多实际使用中的EMP防护设施由于物理限制，例如混凝土墙或土壤，以允许正确应用IEC 61000-4-23:20 00（第1版）中描述的方法。根据经验，许多设施的可用空间仅为1米或更小的间隔。因此，在许多实际情况下，无法根据以前文献的测试方法来测量屏蔽有效性。EMP防护设施的建造者也不愿意建造具有额外空间的设施，用于在屏障之外使用发射天线进行测量，这是由于新建筑物或现有建筑物的操作工作区域的巨大费用和低效率。该文献另外提供了一种方法，该方法允许将发射天线放置在外壳内部并且将接收天线放置在屏障外部(“从内到外”方法)。附录F包括测试集-向上和程序示例。第二版取消并取代了2000年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)更新第5条中的屏蔽有效性(SE)测试方法；b)增加了描述“由内而外”测试方法的新附录F。

IEC 61000-4-23:2016(E) provides a protective devices test method for HEMP and other radiated disturbances. It is primarily intended for HEMP testing but can be applied to other externally generated radiated disturbances where appropriate. It provides a brief description of the most important concepts for testing of shielding elements. For each test, the following basic information is provided:
- theoretical foundation of the test (the test concepts);
- test set-up including outside-to-in and inside-to-out measurements;
- required equipment;
- test procedures;
- data processing.
This international standard does not provide information on requirements for specific levels for testing. Due to the available space, a transmitting antenna position outside the barrier has mainly been suggested. However, nowadays, many EMP protection facilities in practical use do not actually have enough space available outside the electromagnetic barrier due to physical constraints such as concrete walls or soil to allow the method described in IEC 61000-4-23:2000 (edition 1) to be applied correctly. From experience many facilities have available space for a 1 m separation or less only. Therefore, in many practical cases it is not possible to measure shielding effectiveness according to the test method of previous documents. The constructors for EMP protection facilities are also unwilling to build facilities with extra space for measurements with the transmitting antenna outside the barrier due to the great expense and inefficiency of the operational working area for new or existing buildings. This document provides additionally a method that allows the transmitting antenna to be placed inside the enclosure and the receiving antenna outside the barrier ('inside-to-out' method). Annex F includes test set-up and procedure examples. This second edition cancels and replaces the first edition published in 2000. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) updates to the shielding effectiveness (SE) test method in Clause 5;
b) a new Annex F describing methods for testing 'inside-to-out' has been added.
