- Executive summary:
A study was conducted according to OECD TG 110, CIPAC MT 187 and ISO 13320 to determine the particle size distribution of the test item. The particle size distribution was determined using laser diffraction. The test item has a median particle size D50 = 33 µm, which was determined by laser diffraction measurement.
Reference
The median particle size D50 (D (v, 0.5): 50 % of particle volume or particle mass with lower particle diameter) deduced from these distributions is: D50 = 33.2 µm.
The particle size D10 (D (v, 0.1): 10% of particle volume or particle mass with lower particle diameter) deduced from these distributions is: D10 = 7.4 µm.
The particle size D90 (D (v, 0.9): 90 % of particle volume or particle mass with lower particle diameter) deduced from these distributions is:D90 = 115.3 µm.
A standard deviation is not given in the report.
Description of key information
The mean particle size D50 of the test item was 33 µm (reference 4.5-1).
