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:
- 27th February - 27th June 2013
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Study conducted according to EU Test Guidelines at a GLP accredited laboratory
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The particle size distribution was examined using sieve analysis. As less than 10% by weight of the test substance was found to pass a 75 micron sieve, no further testing was required.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- sieving
- Type of distribution:
- mass based distribution
- Percentile:
- D50
- Remarks on result:
- other: Migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.

- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 06 January 2017 - 09 January 2017

- Storage conditions: Room temperature (15 to 25°C)
- Batch number: 101X5
- Purity: > 98%
- Expiry date: October 2017
- Date received: 14 November 2016 - Mass median aerodynamic diameter:
- ca. 310 µm
- Percentile:
- D10
- Mean:
- ca. 9.3 µm
- St. dev.:
- 0
- Percentile:
- D50
- Mean:
- ca. 950 µm
