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
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods with acceptable restrictions
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Laser particle sizer Malvern with unit dry Scirocco 2000
- GLP compliance:
- not specified
- Type of method:
- sieving
- Type of distribution:
- counted distribution
- Percentile:
- D50
- Remarks on result:
- other: Migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.
- No.:
- #1
- Size:
- < 100 µm
- Distribution:
- ca. 42 %
- Conclusions:
- Particle size distribution indicates substance is an inhalation risk (a significant proportion of the particles are present at < 100 µm). This study is considered to be scientifically justified for use as a key study.
