- Conclusions:
- The average particle size results for the test item are: D[10] = 2.77 µm, D[50] = 25.00 µm, D[90] = 85.30 µm, D[3.2]=5.87µm and D[4.3] = 44.20 µm.
Particle size distribution indicates that the substance is not a nanomaterial - Executive summary:
The particle size distribution for the test substance was determined according by laser diffraction with a method similar to ISO 13320 -1 (GLP study). The average particle size results for the test item are: D[10 ]= 2.77 µm, D[50] = 25.00 µm, D[90] = 85.30 µm, D[3.2]=5.87µm and D[4,3] = 44.20 µm.
