标准范围

本文件规定了测定室内空气中悬浮颗粒物（PM）的PM2,5质量浓度的测量方法和策略。它也可用于测定PM10质量浓度。参考法原理包括在颗粒物通过撞击头分离后，在过滤器上收集PM2,5，并通过天平对其进行称重。测量程序和主要要求与EN 12341中规定的条件类似。本文件还规定了操作适当的补充高时间分辨率仪器的程序，这些仪器可用于突出峰值排放、房间调查，并作为参考方法质量控制的一部分。质量保证、测量不确定度的确定和最低限度的报告信息也是本文件的一部分。本文件的较低适用范围为PM2,5的2μg/m3（即标准测量方法的检测限，以其不确定度表示）。本文件不包括生物气溶胶的测定或颗粒的化学特性。有关粉尘成分的测量和评估，请参见ISO 16000系列国际标准中的相关技术规则。本文件不包括车辆和公共交通系统的乘客舱。

This document specifies the measurement methods and strategies for determining the PM2,5 mass concentrations of suspended particulate matter (PM) in indoor air. It can also be used for determining PM10 mass concentration.The reference method principle consists of collecting PM2,5 on a filter after separation of the particles by an impaction head and weighing them by means of a balance.Measurement procedure and main requirements are similar to the conditions specified in EN 12341.This document also specifies procedures for operating appropriate supplementary high time resolution instruments, which can be used to highlight peak emission, room investigation and as part of the quality control of the reference method.Quality assurance, determination of the measurement uncertainty and minimal reporting information are also part of this document.The lower range of application of this document is 2 μg/m3 of PM2,5 (i.e. the limit of detection of the standard measurement method expressed as its uncertainty).This document does not cover the determination of bioaerosols or the chemical characterization of particles. For the measurement and assessment of dust composition, see the relevant technical rules in the International Standards in the ISO 16000 series.This document does not cover passenger compartments of vehicles and public transport systems.
