Applicant's summary and conclusion

Conclusions:
After the mechanical sieving test, it was shown that the majority of the particles (70.5%) of the test item was between 25 µm and 90 µm and 20.5% were lower than 25 µm.

After the laser diffraction test, the following values were obtained for the test item :
- The mean diameter in volume was 43.9 µm.
- The particle size D(10) was 13.5 µm.
- The particle size D(50) was 39.1 µm.
- The particle size D(90) was 81.9 µm.
