Various methods for assessment of dustiness potential
Delft Solids Solutions now offers a variety of instruments and methods to investigate the dustiness potential of (powdered) solids.
The Heubach method quantifies the total suspended dust content. This method is practised in accordance with the German DIN 55992 standard and the total dust is typically expressed in mg/kg (ppm).
Via the Stauber-Heubach method the total dust content can be determined as it is required by a.o. the EFSA (European Food Safety Authority, the EU risk assessment body for food and feed safety) for introduction of new food and feed products on the European market. The dust content is regularly expressed in mg/m3 air.
Delft Solids Solutions also offers dustiness potential analysis following the European EN 15051standard. The approach classifies the collected dust into three fractions: Inhalabe, Thoracic, and Respirable. This enables to correlate how far the particles could penetrate into the respiratory tract and predict their harmfullness.This method is frequently recommended and applied by the US Environmental Protection Agency (EPA).
