Particle size distribution (Granulometry)
Administrative data
Link to relevant study record(s)
- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- October 2017 - April 2018
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- ISO 13320 (Particle size analysis - Laser diffraction methods)
- Deviations:
- yes
- Remarks:
- For particles <50 µm, the MIE model is recommended for calculation of the particle size. However, since the refractive index was not known, the Fraunhofer model was used.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- Laser scattering/diffraction
- Type of particle tested:
- agglomerate
- Type of distribution:
- volumetric distribution
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: 103901

- Percentile:
- D10
- Mean:
- 1.4 µm
- Remarks on result:
- other: Average
- Key result
- Percentile:
- D50
- Mean:
- 7.2 µm
- Remarks on result:
- other: Average
- Key result
- Percentile:
- D90
- Mean:
- 16.6 µm
- Remarks on result:
