Results and discussion
Particle size
- Percentile:
- D50
- Mean:
- 1.47 µm
- Remarks on result:
- other: The particles had a spread of sizes up to 18 µm(migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.)
Any other information on results incl. tables
No other information on the particle size distribution is provided in the report.
Applicant's summary and conclusion
- Conclusions:
- The mean equivalent diameter of the DTBA particles is 1.47 µm.
