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:
- 2011
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: GLP guideline study with acceptable restrictions.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions)
- Version / remarks:
- Method B
- GLP compliance:
- no
- Type of method:
- determination of fibre length and diameter distributions
- Type of distribution:
- mass based distribution
- Percentile:
- D50
- Mean:
- 13.2 µm
- Remarks on result:
- other: Spherical volume: 13.2µm; Cubical volume: 13.0µm
- Conclusions:
- All particles with a mean diameter less than 100 μm have a mass fraction of 0,41 %.
0,023 % / 0,019 % (spherical/ cubical) particles of this mass fraction have a mean diameter less than 4 μm. - Executive summary:
The particle size distribution of triphenyl phosphate was evaluated accoring to OECD TG 110, Method B: Particle Size Distribution/Fibre Length and Diameter Distributions.
All particles with a mean diameter less than100 μm have a mass fraction of 0.41 %. 0.023 % / 0.019 % (spherical/ cubical) particles of this mass fraction have a mean diameter less than 4μm. The mass mediam diameter is 13.2 µm (spherical volume) and 13.0 µm (cubial volume).
Reference
Result sieve fraction:
weighted sample: 4.0507g
weight fraction <100µm: 0.0168g
mass fraction <100µm: 0.41%
Result Particle size distribution: (Sieve fraction <100µm)
Particles with diameter greater than 100μm are due to their aspect ratios up to 1.29.
| Counts | 1195 | |
| Mean Diameter | Aspect Ratio | |
| Minimum | 1.26µm | 1.00 |
| Maximum | 149.60µm | 22.00 |
| Arithmetic mean | 9.08µm | 1.91 |
| Median | 4.02µm | 1.66 |
| Standard deviation | 18.19µm | 1.23 |
Result Mass fraction (calculated): (Sieve fraction < 100µm)
| Particle size | Spherical volume | Cubical volume |
| < 4µm | 0.023% | 0.019% |
| 4 -10µm | 0.24% | 0.19% |
| 10 -100µm | 21.99% | 20.36% |
| >100µm | 77.75% | 79.43% |
| Median (diameter) | 13.2µm | 13.0µm |
Conclusion: All particles with a mean diameter less than100μm have a mass fraction of 0.41%. 0.023% / 0.019% (spherical/ cubical) particles of this mass fraction have a mean diameter less than 4μm.
