Applicant's summary and conclusion

Conclusions:
The L10 D (v, 0.1) was determined to be 2.18 µm, the L50 D (v, 0.5) was determined to be 5.77 µm and the L90 D (v, 0.9) was determined to be 13.67 µm.
Executive summary:

The particle size distribution was determined using the laser diffraction method with wet dispersion according to CIPAC MT 187.

Two measurements have been performed. The L10D (v, 0.1) was determined to be 2.185 µm, the L50D (v, 0.5) was determined to be 5.77 µm and the L90D (v, 0.9) was determined to be 13.67 µm.
