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:
- 8 Sep 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: CIPAC method 187 (particle size analysis by laser diffraction)
- GLP compliance:
- yes
- Type of method:
- Laser scattering/diffraction
- Type of particle tested:
- primary particle
- Type of distribution:
- volumetric distribution
- Percentile:
- D10
- Mean:
- 1.1 µm
- St. dev.:
- 3.5
- Key result
- Percentile:
- D50
- Mean:
- 5.39 µm
- St. dev.:
- 10
- Percentile:
- D90
- Mean:
- 22.4 µm
- St. dev.:
- 2.8
- Conclusions:
- The average particle size distribution results, correct to three significant figures, are D(10) = 1.10 µm, D(50) = 5.39 µm and D(90) = 22.4 µm.
- Executive summary:
The particle size distribution of test substance was determined three times in accordance with the CIPAC method 187, particle size analysis by laser diffraction in compliance with GLP. The average particle size distribution results, correct to three significant figures, are D(10) = 1.10 µm, D(50) = 5.39 µm and D(90) = 22.4 µm.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
