- Mean:
- 574.311 µm
- Remarks on result:
- other: mean of 6 samples
- Percentile:
- D90
- Mean:
- 1 095.964 µm
- Remarks on result:
- other: mean of 6 samples
- Conclusions:
- The particles have a size for d10 of 234.527 µm, for d50 of 574.311 µm and for d90 of 1095.964 µm.
- Executive summary:
The particle size distribution of the test item was assessed via laser diffraction with a Malvern device. The test was performed similar to ISO 13320. It was observed, that the particles have the following sizes and are not existing as nanomaterial:
d10: 234.527 µm
d50: 574.311 µm
d90: 1095.964 µm.
