Inhalable and respirable dust in indoor air by EN 481:1993 and ISO 7708:1995.

Determination of inhalable and respirable dust fractions present in indoor air.

The aerodynamic diameters of the inhalable and respirable dust particles are < 100 µm and < 4 µm, respectively. The price includes a sample collector and a sample pump, which are delivered to the customer for sampling. Results are reported as mg/m³.

According to the decree of the Finnish Ministry of Social Affairs and Health on Hazardous Concentrations (538/2018), the normative threshold value for inhalable dust is 10 mg/m3 on an eight-hour average concentration.
