- Executive summary:
The determination of particle size distribution was carried out using dry sieve test in accordance with OECD Guideline 110 and CIPAC MT 170.
The average d4,3, the mass moment mean (De Brouckere Mean Diameter), was determined to be 85.82 μm. The obtained particle size distribution was as follows (two replicates): over 500 μm: 0.43 %, fraction 300 - 500 μm: 1.08 %, fraction 250 - 300 μm: 2.51 %, fraction 125 - 250 μm: 15.54 %, fraction 75 - 125 μm: 5.16 %, fraction 63 - 75 μm: 16.19 %, fraction 45 - 63 μm: 30.92 %, under 45 μm: 28.19 %.

The average d4,3 – the mass moment mean (De Brouckere Mean Diameter) calculated
according to:
d4.3= Σxidi
Where:
di : the average of the lower and upper sieves
xi : i - mass fraction
The average equivalent diameter was 85.82 μm.
