Conclusions:

The particle size distribution of test substance was determined to be MMD= 13.2 µm

Description of key information

Volumetric distribution:

MMD= 13 µm

D10= 2 µm

D90= 31 µm

Additional information

Bulk form:

The determination was conducted by laser diffraction method in dry conditions.

In addition, the values [vol%] for the particle size fractions are as follows:

<4 µm = 17%

<10 µm= 39%

<100 µm= 96%
