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:
- 12 September 2006 - 6 October 2006
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- sieving
- Type of particle tested:
- primary particle
- Type of distribution:
- other: gravimetric
- Key result
- Percentile:
- D50
- Mean:
- > 100 µm
- Remarks on result:
- other: see remark
- Remarks:
- The mass of test material passing through a 100 μm sieve was measured (1.88%).
- Conclusions:
- By using the sieve method, the proportion of test material having an inhalable particle size less than 100 μm was found to be 1.88%. The results indicate that the test substance has a a particle size that is essentially non-inhalable.

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.
