- St. dev.:
- 0.585
- Conclusions:
- The particle size distribution of the test material according to CIPAC method 187 was determined to be as folows: Dv(10) = 1.04 μm, Dv(50) = 11.5 μm, and Dv(90) = 44.4 μm.
- Executive summary:
The particle size distribution of the test material has been determined using laser diffraction. This study was performed in accordance with the CIPAC method 187 (Fraunhofer diffraction method) using wet-dispersion unit.
The average results, correct to three significant figures, are given below:
Dv(10): 1.04 μm
Dv(50): 11.5 μm
Dv(90): 44.4 μm
