- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2017-08-04
- 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 - Method A: Particle Size Distribution (effective hydrodynamic radius)
- Deviations:
- no
- GLP compliance:
- no
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Type of method:
- Laser scattering/diffraction
- Type of particle tested:
- primary particle
- Specific details on test material used for the study:
- Batch No.: FK650468
Purity: 100% - Percentile:
- D10
- Mean:
- 12.15 µm
- St. dev.:
- 0.36
- Percentile:
- D50
- Mean:
- 138.2 µm
- St. dev.:
- 4.85
- Percentile:
- D90
- Mean:
- 286.9 µm
- St. dev.:
- 8.9
- Conclusions:
- The average of D50 was 138.2 µm and the RSD% was 2.9% (n=3); the average of D10 was 12.15 µm and the RSD% was 3.5% (n=3); the average of D90 was 286.9 µm and the RSD% was 3.1% (n=3).
- Executive summary:
The particle size distribution of test item was tested for three times from preparing test suspension under the same conditions according to OECD 110. Based on the testing results, the average of D50was138.2 µm and the RSD% was 2.9% (n=3); the average of D10was 12.15 µm and the RSD% was 3.5% (n=3); the average of D90was 286.9 µm and the RSD% was 3.1% (n=3).
