Conclusions:
The median particle size D50 of the test item was determiend to be 207 µm.
Executive summary:

A study was conducted according to OECD TG 110, OPPTS 830.7520 and ISO 13320 in order to determine the particle size distribution of the test item. The particle size distribution was determined using laser diffraction. Two test series of 3 measurements each were performed with the test item. The median particle sizes D10, D50 and D90 of the test item were determined to be 21.0 µm, 207 µm and 795 µm respectively.

Description of key information

The median particle size D50 of the test item was determiend to be 207 µm (reference 4.5 -1).
