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:
- 21-23 January 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Data have been generated according to current internationally recognised study guidelines and in accordance with GLP.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions - Method A: Particle Size Distribution (effective hydrodynamic radius)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- Laser scattering/diffraction
- Type of distribution:
- other: Manual sieve and Laser Diffraction
- Mass median aerodynamic diameter:
- 89.65 µm
- Percentile:
- D50
- Mean:
- 68.44 µm
- Remarks on result:
- other: Migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.
- Percentile:
- D10
- Mean:
- 12.112 µm
- Remarks on result:
- other: St. dev is not reported
- Percentile:
- D50
- Mean:
- 68.44 µm
- Remarks on result:
- other: St. dev is not reported
- Percentile:
- D90
- Mean:
- 235.09 µm
- Remarks on result:
- other: St. dev is not reported
- Conclusions:
- The MMAD of the substance was measured as 89.65 µm
- Executive summary:
The particle size distribution of the substance has been measured by initially using a visual microscope and then undertaken more formally using a Laser Diffraction Particle Size Analyser taking into account the requirements of OECD 110 and in compliance with GLP. The MMAD of the substance was measured as 89.65 µm.

Description of key information
The particle size distribution of the substance has been measured by initially using a visual microscope and then undertaken more formally using a Laser Diffraction Particle Size Analyser taking into account the requirements of OECD 110 and in compliance with GLP. The MMAD of the substance was measured as 89.65 µm.
Additional information
Based on the measurement undertaken, around 80% of the substance had a particle size above 10 µm with the MMAD of the substance was measured as 89.65 µm
