Results and discussion
Particle sizeopen allclose all
- Percentile:
- D50
- Mean:
- ca. 5 mm
- Remarks on result:
- other: based on visual assessment(migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.)
- Percentile:
- other: 100%
- Mean:
- ca. 5 mm
- Remarks on result:
- other: based on avisual assessment
Particle size distribution at different passages
- Remarks on result:
- other: this not possible to determined as the results are based on a visual assessment
Any other information on results incl. tables
as the particle size distribution is based on a visual assessment, it is not possible to fill out the fiels "particle size at differnt passages"
Applicant's summary and conclusion
- Conclusions:
- the visual assessment was performed in preference of the sieving procedure referenced in OECD guideline 110, 12 may 1981; however the observations confirmed the absence of any fraction with a particle size below 100µm, defined as the "inhalable fraction" in the european commission technical guidance document "particle size distribution, fibre length an,d diameter distribution"(june 1996), which satisfies the requirement of OECD guideline 110, 12 may 1981.
The test item was visually assessed to be a cream coloured, opaque disk shaped pellets, with one flat side and one convex side. The test item was of a uniform particle size distribution, with individual pellets having a diameter of approximately 5 mm. no finer fraction (for example dust) was observed in the sample. - Executive summary:
