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:
- 22 Dec 2017
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- ISO 13320 (Particle size analysis - Laser diffraction methods)
- Deviations:
- not applicable
- Principles of method if other than guideline:
- Method used was laser diffraction. The technique of laser diffraction is based on the principle that particles passing through a laser beam will scatter light at an angle that is directly related to their size: large particles scatter at low angles, whereas small particles scatter at high angles. The method is standardized [ISO 13320-1: 1999 Particle size analysis - Laser diffraction methods - Part 1: General principles].
- GLP compliance:
- no
- Type of method:
- Laser scattering/diffraction
- Type of particle tested:
- primary particle
- Type of distribution:
- volumetric distribution
- Key result
- Percentile:
- D50
- Mean:
- >= 1 - <= 3 µm
- Remarks on result:
- not measured/tested
- Percentile:
- D50
- Mean:
- <= 15 µm
- Remarks on result:
- not measured/tested
- Conclusions:
- The particle size is is < 15 microns with a typical range from 1 to 3 microns
- Executive summary:
The particle size distribution was analysed using laser diffraction. The method is standardized [ISO 13320-1: 1999 Particle size analysis - Laser diffraction methods - Part 1: General principles].
The x50value is determined by the customers' requirements and is < 15 microns with a typical range is 1 to 3 microns.

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.
