静电学.第2-1部分:材料和产品损耗静电荷的能力的测量方法

[中文适用范围]： IEC 61340的这一部分描述了测量绝缘和静电耗散材料和产品的静电荷耗散率的测试方法。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，一种使用电晕充电，一种使用带电金属板，是不同的，可能不会给出相同的结果。然而，每种方法都有其最适合的一系列应用。电晕充电方法适用于评估材料（例如纺织品、包装等）从其自身表面消散电荷的能力。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消散放置在其上或与之接触的导电物体的电荷的能力。带电板方法可能不适合评估材料从其自身表面消散电荷的能力。除了一般应用之外，该横向标准还供技术委员会根据 IEC 指南 108 中规定的原则制定标准。技术委员会的职责之一是，在适用的情况下，制定标准在编写其出版物时使用横向标准。除非特别提及或包含在相关出版物中，否则本横向标准的内容不适用。 [外文原描述]： IEC 61340-2-1:2015 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 .
