Applicant's summary and conclusion
- Conclusions:
- Test item shows a particle size distribution of d10= 37 µm, d50 = 111 µm and d90 = 229 µm.
The mass median aerodynamic diameter (MMAD) of the test item is calculated as ca. 111 µm (D50).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
