Applicant's summary and conclusion
- Conclusions:
- The mass median diameter (D50) of the volumetric particle size distribution of the substance is 9.3 µm.
- Executive summary:
The volumetric particle size distribution ot the substance was determined according ISO 13320 -1 using a Malvern Mastersizer 2000 instrument with the vibrating tray unit Scirocco 2000. The mass median diameter (D50) of the substance was found to be 9.3 µm.
