标准摘要
[中文适用范围]： IEC 61340 的这一部分提供了用于评估和选择空气电离设备和系统（电离器）的测试方法和程序。本文件建立了在指定条件下的测量技术，以确定电离器的偏移电压（离子平衡）和衰减（电荷中和）时间。本文件不包括电磁干扰 (EMI) 的测量，也不包括与军械、易燃物、爆炸物或电引发爆炸装置有关的电离器的使用。如本文件中所包含的，离子发生器制造商可以使用测试方法和测试条件来提供描述其产品的性能数据。敦促离子发生器的用户修改其特定应用的测试方法和测试条件，以便使离子发生器合格，或定期验证离子发生器的性能。用户将决定每个应用程序所需的数据范围。注意：本文档中描述的程序和设备可能会使人员暴露在危险的电气和非电气条件下。本文件的用户有责任选择符合适用法律、监管规范以及外部和内部政策的设备。请用户注意，本文档不能取代或取代任何人员安全要求。 [外文原描述]： IEC 61340-4-7:2017 provides test methods and procedures for evaluating and selecting air ionization equipment and systems (ionizers). This document establishes measurement techniques, under specified conditions, to determine offset voltage (ion balance) and decay (charge neutralization) time for ionizers. This document does not include measurements of electromagnetic interference (EMI), or the use of ionizers in connection with ordnance, flammables, explosive items or electrically initiated explosive devices. As contained in this document, the test methods and test conditions can be used by manufacturers of ionizers to provide performance data describing their products. Users of ionizers are urged to modify the test methods and test conditions for their specific application in order to qualify ionizers for use, or to make periodic verifications of ionizer performance. The user will decide the extent of the data required for each application. This edition includes the following significant technical changes with respect to the previous edition: - the use of contacting plate voltage measurements in addition to the previous non-contacting plate voltage measurements has been added. Charged plate monitors (CPMs) using this technology have been in use in the industry for many years.
