Any other information on results incl. tables
Based on fibre diameter analysis 81.4% of the measured fibres (i.e. 70) has a diameter between 0.1 and 0.5 µm and 18.6% of the fibres has a diameter between 0.5 and 1 µm.
See also attached background material.
The average fibre length was determined to be 9.998 µm (min = 4.547 µm, max = 20.084 µm).
The average fibre diameter was determined to be 0.373 µm (min = 0.187 µm, max = 0.656 µm).
Applicant's summary and conclusion
- Conclusions:
- The substance was found to have an average fibre length of ca. 10 µm and an average firbre diameter of ca. 0.37 µm.
