用于粒子特性描述的气溶胶粒子的电荷调节以及校准和测试气溶胶的产生

[中文适用范围]： 本文件规定了用于气溶胶颗粒（特别是粒径和浓度测量以及分类的颗粒特性）的电荷调节器的要求和使用指南。本文件提供了一种方法来指定电荷调节器的性能，并对其质量控制提出要求，特别是在以下应用中：- 使用差分迁移率分析系统（DMAS）进行粒子大小和浓度测量；- 使用差分电气迁移率分类器（DEMC）进行粒子大小分类。对于这些应用，本文件涵盖粒径从约1 nm到1 μm的颗粒以及电荷调节器入口处的颗粒数浓度高达约10^7 cm^-3的情况。本文件未涉及特定电荷调节器设计或其他未在第1章中规定的应用。含放射性源或X射线管的电荷调节器的辐射安全不在本文件范围内。 [外文原描述]： This document specifies requirements and provides guidance for the use of charge conditioners for aerosol particles, especially for particle characterization and for the generation of calibration and test aerosols. This document provides a methodology to specify the performance of charge conditioners and for adequate quality control, with respect to their application in: — particle size and concentration measurement with differential mobility analysing systems (DMAS); —particle size classification with differential electrical mobility classifiers (DEMC). For these applications, this document covers particle charge conditioning for particle sizes ranging from approximately 1 nm to 1 µm and for particle number concentrations at the inlet of the charge conditioner up to approximately 10 7 cm -3 . This document does not address specific charge conditioner designs or other applications besides those specified in Clause 1. Radiation safety for charge conditioners with radioactive sources or x-ray tubes is not covered by this document.
