Applicant's summary and conclusion
- Conclusions:
- Using the laser diffraction test (‘wet’, small volume dispersion system), the Mass Median Aerodynamic Diameter (MMAD) of the test substance was determined to be 8.438 µm. Furthermore it was determined that 60.50 % by volume of sample was < 10.00 μm.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
