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:
- 25/09/2006 = 12/10/2006
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- No guideline is specified within the text of the report.
- GLP compliance:
- no
- Type of method:
- Laser scattering/diffraction
- Remarks:
- Given the use of a Mastersizer 2000, the method must have been laser diffraction as this is how this equipment measures particle size.
- Percentile:
- D10
- Mean:
- 15.629 µm
- St. dev.:
- 0
- Remarks on result:
- other:
- Remarks:
- The standard deviation is not provided in the results
- Percentile:
- D50
- Mean:
- 146.172 µm
- St. dev.:
- 0
- Remarks on result:
- other:
- Remarks:
- The standard deviation is not provided in the results
- Percentile:
- D90
- Mean:
- 571.592 µm
- St. dev.:
- 0
- Remarks on result:
- other:
- Remarks:
- The standard deviation is not provided in the results
- Conclusions:
- Less than 10% of the substance has a particle size below 15.629 µm.
- Executive summary:
Using a Malvern Mastersizer 2000, the particle size has been determined. Less than 10% of the test material has a particle size below 15.629 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.
