标准摘要
[中文适用范围]： 本文件规定了一种用于测量悬浮在气体中的颗粒的尺寸、数量浓度和基于数量的尺寸分布的光散射气溶胶光谱仪（LSAS）的特性。本文件提供了气溶胶光谱仪的校准程序和验证方法。本文件适用于：- 药用计量吸入器（MDI）、干粉吸入器（DPI）和雾化器的表征；- 活性成分的生产过程控制；- 截止点测定：冲击器、旋风分离器和撞击器；- 大气气溶胶：生物气溶胶、稳定或堆肥设施、雾化液滴、街道隧道内的测量；- 过滤器分级分离效率的测定。 [外文原描述]： This document specifies characteristics of a light scattering aerosol spectrometer (LSAS) which is used for measuring the size, number concentration and number-based size distribution of particles suspended in a gas. This document provide the calibration procedure and the validation method for aerosol spectrometers. This document applies to: — characterization of metered dose inhalers (MDI), dry powder inhalers (DPI) and nebulizers in pharmacy; — production control of active agents; — cut-off determination: impactors, cyclones and impingers; — atmospheric aerosols: bio-aerosols, stables or composting facilities, nebulized droplets, measurements in street tunnels; — fractional separation efficiency determination of filters.
