- This standard specifies the β-ray method for the automatic determination of particulate matter (PM10 and PM2.5) in ambient air. This standard applies to the automatic determination of particulate matter (PM10 and PM2.5) in ambient air. When the instrument range is 0 μg/m3 ~ 1000 μg/m3, the detection limit of this standard method is 1 μg/m3, and the lower determination limit is 4 μg/m3. The mass concentration in this standard refers to the concentration under actual conditions (atmospheric temperature and pressure during monitoring).
