- Key result
- Percentile:
- D50
- Mean:
- >= 529.2 - <= 564.8 µm
- St. dev.:
- 17.9
- Percentile:
- D90
- Mean:
- >= 1 001 - <= 1 012 µm
- St. dev.:

- Conclusions:
- The median particle size (d50) of Cyanamid F1000 is 548 µm.
- Executive summary:
The particle size distribution (volume distribution) of Cyanamid F1000 was measured by laser diffraction with dry dispersing according to ISO 13321. The d10, d50 and d90 percentile were determined in three measurements to be d10 = 235 µm, d50 = 548 µm and d90 = 1006 µm.
