Reference
The test item consisted of particles of various shapes and was partially translucent.
The median particle size L50 (C(v, 0.5): 50 % of particle volume or particle mass with lower particle diameter):
1st test series: L50 = 26.77 µm
2nd test series: L50 = 26.54 µm
The average of the median particle size L50:
L50 = 26.7 µm
The particle size L10 (D (v, 0.1): 10 % of particle volume or particle mass with lower particle diameter):
1st test series: L10= 7.69 µm
2nd test series: L10= 7.78 µm
The average of the particle size L10:
L10= 7.7 µm
The particle size L90 (D (v, 0.9): 90 % of particle volume or particle mass with lower particle diameter):
1st test series: L90= 101.69 µm
2nd test series: L90= 98.63 µm
The average of the particle size L90:
L90= 100.2 µm
The measurements showed maxima at approximately <1 µm and 20 µm. A shoulder was observed at approximately 300 µm.

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.
