- Executive summary:
A study was conducted according to OECD TG 110 determine the particle size distribution of the test item. The particle size distribution was determined by dry sieving as only approximately 50 % of the test item passed a 1000 µm sieve and thus laser diffraction was therefore not applicable. 235.89 g of the test item were placed on the top sieve. After closing the sieve stack and placing it into the sieving machine sieving was performed for 4 min with amplitude of 1.0 mm. The median particle sizes D10, D50 and D90 were determined to be 500 µm, 1250 µm and 2350 µm, respectively.

Description of key information
The median particle sizes D10, D50 and D90 were determined to be 261 µm, 605 µm and 1270 µm, respectively.
Additional information
A study was conducted according to OECD TG 110 determine the particle size distribution of the test item (reference 4.5 -1). The particle size distribution was determined by dry sieving as only approximately 50 % of the test item passed a 1000 µm sieve and thus laser diffraction was therefore not applicable. 235.89 g of the test item were placed on the top sieve. After closing the sieve stack and placing it into the sieving machine sieving was performed for 4 min with amplitude of 1.0 mm. The median particle sizes D10, D50 and D90 were determined to be 500 µm, 1250 µm and 2350 µm, respectively.
