Percentile:
D50
Mean:
> 0.2 other:
Remarks on result:
other: The method allows detection of particle bigger than 0.2 mm. (migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.)

Any other information on results incl. tables

Mill scale is not a fine powder: typical range of mill scale particles rises from 0.2 up to 4 mm and above. A summary of the analysis results is provided in the executive summary section.

Applicant's summary and conclusion

Conclusions:
The method allows detection of particle bigger than 0.2 mm. Mill scale is not a fine powder: typical range of mill scale particles rises from 0.2 up to 4 mm and above.
