- Executive summary:
A study was conducted to determine particle size distribution of the test substance according to EN 14034. The particle size was determined using apparatus Malvern Mastersizer 2000. Under the study conditions, following size distibution of the test substance particles was determined: D10 - 3.778 µm, D50 - 11.618 µm and D90 - 26.673 µm (Martens, 2013).
