Conclusions:

The L10 D (v, 0.1) was determined to be 5 µm, the L50 D (v, 0.5) was determined to be 27 µm and the L90 D (v, 0.9) was determined to be 201 µm.

Executive summary:

The particle size distribution of a dried sample was determined using the laser diffraction method with dry dispersion. The particle size distribution of test item was determined following CIPAC MT 187. The dispersing energy was adjusted to 4.0 bar. Eight measurements have been performed. The following mean results were obtained. The L₁₀D (v, 0.1) was determined to be 5 µm, the L₅₀D (v, 0.5) was determined to be 27 µm and the L₉₀D (v, 0.9) was determined to be 201 µm.
