- Percentile:
- D50
- Mean:
- 17.8 µm
- St. dev.:
- 0.047
- Percentile:
- D90
- Mean:
- 146.9 µm
- St. dev.:

- Executive summary:
A study was performed in accordance with OECD TG 110 and ISO 13320 in order to determine the particle size distribution of the the test item. Two test series of three measurements each was performed. The test item has a median particle size D50 = 18 µm, which was determined by laser diffraction measurement
