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:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Principles of method if other than guideline:
- The test was performed according to the SOP - STR 071 protocol.Laser light scattering.The particle size distribution was analyzed using the Mastersizer 2000 tool, which uses the technique of laser diffraction to measures the size of particles. It measures the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analyzed to calculate the size of the particles that created the scattering pattern. The sample was dispersed, stirred and ultrasonicated prior the analytical characterisation by light scattering.
- GLP compliance:
- no
- Type of method:
- Laser scattering/diffraction
- Type of distribution:
- volumetric distribution
- Percentile:
- D10
- Mean:
- ca. 15.9 µm
- St. dev.:
- 2
- Percentile:
- D50
- Mean:
- ca. 34.6 µm
- St. dev.:
- 5
- Percentile:
- D90
- Mean:
- ca. 66.8 µm
- St. dev.:
- 5
- Conclusions:
- The substance particle size distribution was measured by light scattering and the results are D10 = 15.9 µm, D50 = 34.6 µm and D90 = 66.8 µm.
- Executive summary:
The substance particle size distribution was measured by light scattering and the results are D10 = 15.9 µm, D50 = 34.6 µm and D90 = 66.8 µm.

Description of key information
D10 = 15.9 µm
D50 = 34.6 µm
D90 = 66.8 µm
Additional information
The particle size distribution was determined by light scattering (REACH&Colours Kft, 2015) and resulted to have the following parameters D10 = 15.9 µm, D50 = 34.6 µm and D90 = 66.8 µm.
