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:
- 2012-02-07 to 2012-02-07
- 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)
- GLP compliance:
- no
- Type of method:
- Laser scattering/diffraction
- Percentile:
- D10
- Mean:
- 2.84 µm
- Remarks on result:
- other: The particle size L10 (D (v, 0.1): 10 % of particle volume or particle mass with lower particle diameter)
- Percentile:
- D50
- Mean:
- 17.74 µm
- Remarks on result:
- other: The median particle size L50 (D (v, 0.5): 50 % of particle volume or particle mass with lower particle diameter)
- Percentile:
- D90
- Mean:
- 39.33 µm
- Remarks on result:
- other: The particle size L90 (D (v, 0.9): 90 % of particle volume or particle mass with lower particle diameter)
- Conclusions:
- The particle size distribution of Tellurium dioxide was determined by laser diffraction (light scattering). The test item consists of a powder which tends to agglomerate.
The particle size L10 of the test item deduced from the particle size distributions is 2.84 µm.
The particle size L50 of the test item deduced from the particle size distributions is 17.74 µm.
The particle size L90 of the test item deduced from the particle size distributions is 39.33 µm. - Executive summary:
In a study conducted according to OECD guideline 110 the particle size distribution of the test item was determined by laser diffraction (light scattering). The test item consists of a powder which tends to agglomerate.
The particle size L10 of the test item deduced from the particle size distributions is 2.84 µm.
The particle size L50 of the test item deduced from the particle size distributions is 17.74 µm.
The particle size L90 of the test item deduced from the particle size distributions is 39.33 µm.
