中文名称：室内空气 第37部分：PM2.5浓度的测量

英文名称：Indoor air — Part 37: Measurement of PM2,5 mass concentration

发布日期：2019-02

标准范围

This document specifies the measurement methods and strategies for determining the PM_2,5 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 PM_2,5 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 PM_2,5 (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.
