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:
- 13 September 1999 to 6 January 2000
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions)
- GLP compliance:
- yes
- Type of method:
- microscopic examination
- 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.
- Conclusions:
- The results indicate that 0.2% by mass of HP-10 is smaller than 10 μm.
- Executive summary:
A study was performed to determine particle size distribution of HP-10. The method followed was OECD Guidelines for the Testing of Chemicals, Method 110.
The particle size distribution was initially examined using sieve analysis. As greater than 10% by weight of the test substance was found to pass a 75 micron sieve, it was further examined by image analysis.
The results indicate that 0.2% by mass of HP-10 is smaller than 10μm.
Reference
