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:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions)
- Version / remarks:
- Screening Test
- Principles of method if other than guideline:
- The method used is based on a procedure designed to comply with that given in 'Particle size distribution, fibre length and diameter distribution', June 1996 European Commission technical guidance document, which satisfies the requirements of OECD Guideline 110
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- sieving
- Type of particle tested:
- primary particle
- Type of distribution:
- mass based distribution
- No.:
- #1
- Size:
- < 100 µm
- Distribution:
- 10 %
- Remarks on result:
- other:
- Remarks:
- Proportion of test item < 100 µm was 10.0%
- Conclusions:
- The proportion of rhodium trichloride (hydrate) <100 μm was 10.0%.
- Executive summary:
This is a GLP compliant study following OECD guideline 110 (screening test) and is considered to be suitable for use as the key study for this endpoint. The proportion of rhodium trichloride (hydrate ) <100 μm is 10.0 %.

Additional information
Tremain and Atwal (2011) is a GLP compliant study following OECD guideline 110 (screening test) and is considered to be suitable for use as the key study for this endpoint.
The proportion of rhodium trichloride (hydrate ) <100 μm is 10.0 %.
