- 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) - Method B: Fibre Length and Diameter Distributions
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- sieving
- Type of particle tested:
- primary particle
- Type of distribution:
- mass based distribution
- Mass median aerodynamic diameter:
- 60.51 µm
- No.:
- #1
- Size:
- >= 10 - <= 100 µm
- Distribution:
- 100 %
- Remarks on result:
- other: sieve fraction nominal < 100 µm
- Conclusions:
- The MMAD (Mass Median Aerodynamic Diameter < 100 μm) of the test item has a value of 60.51 μm as spherical particles.
- Executive summary:
Determination of the particle size distribution of the test item was determined by scanning electron microscopy after the samples was fractionated by a 100 μm sieve following OECD Guidelines No: 110 method B. For the determination of the particle size and the aspect ratio, 6 pictures have been taken by SEM (scanning electron microscope) at a magnification of 50 times. The MMAD (Mass Median Aerodynamic Diameter < 100 μm) has a value of 60.51 μm as spherical particles.
