Applicant's summary and conclusion
- Conclusions:
- The particle size distribution was investigated based on the theory of laser diffraction with the following results:
D10 = 1.013 μm
D50 = 1.968 μm= mass median diameter (MMD)
D90 = 3.041 μm (respirable fraction: < 4µm)
The study was performed in accordance with generally accepted scientific standards and described in sufficient detail and therefore reliability of Klimisch 2 has been assigned.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
