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
- Remarks:
- Study conducted to GLP and in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not effect the quality of the relevant results.
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- The method was designed to comply with that given in 'Particle Size Distribution, Fibre Length and Diameter Distribution' June 1996 European Commission technical guidance document.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- determination of fibre length and diameter distributions
- Type of distribution:
- volumetric distribution
- Remarks on result:
- not determinable
- No.:
- #1
- Size:
- >= 100 µm
- Distribution:
- ca. 95.8 %
- Remarks on result:
- other: 4.2% of test material passed through the Sieve aperture of 100µm
- Conclusions:
- The proportion of test material found to have a particle size of less than 100µm was 4.2%. The test material is considered essentially non inhalable.
- Executive summary:
Method
The determination was made using a method designed to be compatible with that given in 'Particle Size Distribution, Fibre Length and Diameter Distribution' June 1996 European Commission technical guidance document.
Conclusion
By Sieve analysis the proportion of test material found to have a particle size of less than 100µm was 4.2%. The test material is considered essentially non inhalable
Reference
By sieve analysis, the proportion of test material found to have a particle size of less than 100 µm was 4.2%
Description of key information
The proportion of test material found to have a particle size of less than 100µm was 4.2%. The test material is considered essentially non inhalable.
Additional information
The proportion of test material found to have a particle size of less than 100µm was 4.2%. The test material is considered essentially non inhalable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
