Indoor air - Measurement of PM_2,5 mass concentration Ingestion-build-73935 quality assessment procedures and the1 Scope This document specifies the measurement methods and strategies for determining the PM2,5mass concentrations of suspended particulate matter (PM) in indoor air. It can also be used for determining PM10mass 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
