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:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Justification for type of information:
- Data is from experimental study
- Qualifier:
- according to guideline
- Guideline:
- other: as mentioned below
- Principles of method if other than guideline:
- The particle size distribution of test chemical was determined by granulometric analysis with rotap sieve shaker. The principle includes measurement of relative amounts of particles present, sorted according to size
- GLP compliance:
- no
- Type of method:
- sieving
- Type of particle tested:
- primary particle
- Type of distribution:
- counted distribution
- Key result
- Percentile:
- D50
- Remarks on result:
- other: Migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.
