标准范围

本文件提供了通过分析气溶胶粒子的电迁移率来确定气溶胶粒子数尺寸分布的指南和要求。这种测量通常被称为“气溶胶粒子的微分电迁移率分析”。本分析方法适用于约1 nm至1μm范围内的粒度测量。本文件不涉及不同应用的具体仪器设计或粒度分布测量的具体要求，但包括不确定度的计算方法。在本文件中，用于执行差分电迁移率分析的完整系统称为DMAS（差分电迁移率分析系统），而该系统中根据其电迁移率对颗粒进行分类的元件称为DEMC（差分电迁移率分类器）。注:本文件不包括DMA应用的技术要求和规范，这些要求和规范在特定应用标准或指南中定义，例如道路车辆应用（ISO/TC 22）、环境测量（ISO/TC 146）或纳米技术（ISO/TC 229）。

This document provides guidelines and requirements for the determination of aerosol particle number size distribution by means of the analysis of electrical mobility of aerosol particles. This measurement is usually called "differential electrical mobility analysis for aerosol particles". This analytical method is applicable to particle size measurements ranging from approximately 1 nm to 1 μm. This document does not address the specific instrument design or the specific requirements of particle size distribution measurements for different applications but includes the calculation method of uncertainty. In this document, the complete system for carrying out differential electrical mobility analysis is referred to as DMAS (differential mobility analysing system), while the element within this system that classifies the particles according to their electrical mobility is referred to as DEMC (differential electrical mobility classifier).NOTE This document does not include technical requirements and specifications for the application of DMAS, which are defined in application specific standards or guidelines, e.g. for road vehicle applications (ISO/TC 22), environmental measurements (ISO/TC 146) or nanotechnologies (ISO/TC 229).
