- Conclusions:
- Cumulative distribution:
d(0.10): 125 µm
d(0.50): 291 µm
d(0.90): 579 µm
Average particle size in surface area D[3,2]: 103 μm
Average particle size in volume D[4,3]: 325 μm
Reference
The obscuration value is 23.35%, conforms to the requirement for testing.
The determination result can be considered valid.

Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
