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
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: CIPAC MT 187
- Qualifier:
- according to guideline
- Guideline:
- ISO 13320 (Particle size analysis - Laser diffraction methods)
- Principles of method if other than guideline:
- Method takes also OECD Guideline 110 into account.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- Laser scattering/diffraction
- Type of distribution:
- volumetric distribution
- Specific details on test material used for the study:
- Batch 3033900250
- Mass median aerodynamic diameter:
- 22.58 µm
- Geometric standard deviation:
- 1.146
- Percentile:
- D90
- Mean:
- 11.8 µm
- St. dev.:
- 0.028
- Percentile:
- D50
- Mean:
- 9.76 µm
- St. dev.:
- 0.005
- Percentile:
- D10
- Mean:
- 8.09 µm
- St. dev.:
- 0.018
- Conclusions:
- The particle size of the test substance was determined with Laser Diffraction on 5 runs according to ISO 13320, CIPAC MT 187 and taking OECD guideline 110 into account. The following average results were obtained:
D10: 8.09 µm +- 0.0180 µm
D50: 9.76 µm +- 0.00524 µm
D90: 11.80 µm +- 0.0281 µm
MMAD : 22.58 µm +- 0.011 µm - Executive summary:
The particle size of the test substance was determined with Laser Diffraction on 5 runs according to ISO 13320, CIPAC MT 187 and taking OECD guideline 110 into account. The following average results were obtained:
D10: 8.09 µm +- 0.0180 µm
D50: 9.76 µm +- 0.00524 µm
D90: 11.80 µm +- 0.0281 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.
