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:
- 2016-08-03 to 2016-08-05
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study

- yes (incl. QA statement)
- Type of method:
- Laser scattering/diffraction
- Type of particle tested:
- other: Sample sieved, fraction <2000um tested
- Type of distribution:
- mass based distribution
- Specific details on test material used for the study:
- Batch CP2684
- Mass median aerodynamic diameter:
- 266.39 µm
- Geometric standard deviation:
- 0.3
- Percentile:
- D10
- Mean:
- 23.523 µm
- St. dev.:
- 0.4
- Percentile:
- D50
- Mean:
- 154.575 µm
- St. dev.:
- 0.3
- Percentile:
- D90
- Mean:
- 376.811 µm
- St. dev.:

- Conclusions:
- Manual sieve analysis indicated that 85.1 % by weight of the sample had a particle size of < 2000 µm. The analysis was conducted using the small volume (wet) module (SVM) with kerosene as the dispersant. The results of the laser diffraction test conducted to determine the particle size of the fraction of sample < 2000 µm was that the sample had a MMAD of 266.39 um.
- Executive summary:
Manual sieve analysis indicated that 85.1 % by weight of the sample had a particle size of <2000 um. The analysis was conducted using the small volume (wet) module (SVM) with kerosene as the dispersant. The results of the laser diffraction test conducted to determine the particle size of the fraction of sample <2000 um are summarised below:

Description of key information
nual sieve analysis indicated that 85.1 % by weight of the sample had a particle size of < 2000 um.
Manual sieve analysis indicated that 85.1 % by weight of the sample had a particle size of < 2000 um.
The MMAD determined by laser diffraction was 266.390 um.
The analysis was conducted using the small volume (wet) module (SVM) with kerosene as the dispersant. The results of the laser diffraction test conducted to determine the particle size of the fraction of sample < 2000 um gave an MMAD of 266.39 um.
