The law for maintenance of sanitation in buildings establishes the building sanitation management standards and the methods for monitoring indoor environments in buildings. Suspended particles, one of the monitoring items in the law, are measured by the gravimetric method with a low-volume air sampler or equivalent methods with calibrated equipment, such as a dust meter. Dust meters have been commonly used to monitor indoor particle concentrations in buildings. Mass concentration in indoor are calculated with the data from dust meters and the coefficient of calibration, K value. This paper reports the overview about the methods of measurement for suspended particle concentration and calibration for dust meters , the K value in the law. The relationship between suspended particle concentrations in recent office buildings is discussed.
