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:
- ISO 13320 (Particle size analysis - Laser diffraction methods)
- Deviations:
- no
- Principles of method if other than guideline:
- The analysis was carried out using the Coulter LS230 Laser Diffraction Particle Size Analyser fitted with the Variable Fluids Module. Before adding to the instrument, the sample was pre-dispersed by mixing to a paste using a small amount of surfactant in solution. The material was run multiple times on the instrument. The runs were averaged and it is the averaged distributions that are shown.
- GLP compliance:
- no
- Remarks:
- No work reported in this document, unless otherwise stated, was carried out under the terms of the U KAS accreditation for UKAS Laboratory No 0967.
- Type of method:
- Laser scattering/diffraction
- Type of particle tested:
- other: not specified
- Type of distribution:
- counted distribution
- Key result
- Percentile:
- D50
- Mean:
- 48.7 µm
- St. dev.:
- 48.7
- Conclusions:
- The test item is a pale yellow material with median particle sizes in the range 30 to 50µm.

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.
