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:
- 2017
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Principles of method if other than guideline:
- The apparatus uses the phenomenon of scattered light from three laser beams projected through a stream of particles. The amount and direction of light scattered by the particles is measured by an optical array and then analyzed by the apparatus software to determine the theoretical diameter of a sphere with an equivalent volume.
- GLP compliance:
- no
- Type of method:
- Laser scattering/diffraction
- Type of distribution:
- volumetric distribution
- Remarks on result:
- not measured/tested
- Key result
- Percentile:
- D10
- Mean:
- 44.09 µm
- St. dev.:
- 2.7
- Remarks on result:
- other: standard deviation not available
- Key result
- Percentile:
- D50
- Mean:
- 233.78 µm
- St. dev.:
- 45.5
- Remarks on result:
- other: standard deviation not available
- Key result
- Percentile:
- D90
- Mean:
- 823.05 µm
- St. dev.:
- 237.4
- Remarks on result:
- other: standard deviation not available
- Conclusions:
- The particle size range of the test item is included between1408 µm and 11.00 µm
- Executive summary:
The particle size range of the test item was determined during an experimental study performed according to the Laser scattering/diffraction method (Solvay, 2017).
This range is between 1408 µm and 11.00 µm. The test item shows the following charateristics:
d90 = 823.05 µm
d50 = 233.78 µm
d10 = 44.09 µm
Reference
The lowest diameter was between: 13.08 and 11.00 µm
Description of key information
The particle size of the test item was detemined in a key study of Klimisch validity 2 performed according to the Laser scattering/diffraction method.
Additional information
The particle size range of the test item is between 1408 µm and 11.00 µm. The test item posses the following charateristics:
d90 = 823.05 µm
d50 = 233.78 µm
d10 = 44.09 µm
