IEC 61340-2-1:20 5+AMD1:2022描述了测量绝缘体和静电耗散材料和产品静电荷耗散率的试验方法。它包括测试方法的一般描述和特定应用的详细测试程序。测量电荷衰减时间的两种测试方法，一种是电晕充电，另一种是带电金属板，是不同的，可能不会给出等效的结果。然而，每种方法都有一系列最适合的应用。电晕充电方法适用于评估材料(例如纺织品、包装等)从其自身表面耗散电荷的能力。带电金属板法适用于评估手套、指套、手动工具等材料和物体的能力。消散放置在导电物体上或与导电物体接触的电荷。带电板法可能不适合评估材料从自身表面耗散电荷的能力。除了其一般应用之外，该水平标准还旨在供技术委员会根据IEC指南108中规定的原则制定标准时使用。与上一版相比，此版本包括以下重大技术变更: a)第一版支持IEC TR 61340-5-1中的要求，但随着IEC TR 61340-5-1修订为国际标准，不再需要这种支持；对IEC 61340-5-1的引用已被删除； b)引言提供了有关电荷衰减时间测量何时合适以及两种测试方法中的每一种最适合的应用的附加信息；c)增加了电晕充电法测量仪器性能检定的程序。 根据IEC指南108，它具有水平标准的地位。

IEC 61340-2-1:2015+AMD1:2022 describes test methods for measuring the rate of dissipation of static charge of insulating and static dissipative materials and products. It includes a generic description of test methods and detailed test procedures for specific applications. The two test methods for measuring charge decay time, one using corona charging and one using a charged metal plate are different and may not give equivalent results. Nevertheless, each method has a range of applications for which it is best suited. The corona charging method is suitable for evaluating the ability of materials, e.g. textiles, packaging, etc., to dissipate charge from their own surfaces. The charged metal plate method is suitable for evaluating the ability of materials and objects such as gloves, finger cots, hand tools, etc. to dissipate charge from conductive objects placed on or in contact with them. The charged plate method may not be suitable for evaluating the ability of materials to dissipate charge from their own surfaces. In addition to its general application, this horizontal standard is also intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 108. This edition includes the following significant technical changes with respect to the previous edition:
a) the first edition supported requirements in IEC TR 61340-5-1, but with the revision of IEC TR 61340-5-1 into an International Standard, this support is no longer required; references to IEC 61340-5-1 have been removed;
b) the introduction gives additional information on when charge decay time measurements are appropriate, and the applications for which each of the two test methods are best suited;
c) procedures for performance verification of measuring instruments for the corona charging method have been added.
It has the status of a horizontal standard in accordance with IEC Guide 108.
