ISO DIS 16000-37

Description / Abstract: This part of ISO 16000 specifies the measurement methods and strategies for determining the PM_2,5 mass concentrations of suspended particulate matter in indoor air. This standard can also be used for determining PM10 mass concentration.

The reference method principle consists in 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 International Standard also gives 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 insurance, determination of the measurement uncertainty and minimal reporting information are also part of this standard. The lower range of application of this International Standard is 2 μg/m³ of PM₂,₅ (i.e. the limit of detection of the standard measurement method expressed as its uncertainty).

This International Standard does not cover the determination of bioaerosols or the chemical characterisation 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 International Standard does not cover passenger compartments of vehicles and public transport systems.
