VMD (Volume Mean Diameter)= 15.29 µm

SMD (Sauter Mean Diameter)= 5.10 µm

Conclusions:
The particle size distribution of test substance was determined to be MMD= 11.5 µm
Executive summary:

In this guideline-equivalent (ISO 13320) study the particle size of the test material (EC 404-360-3) was determined to be MMD= 11.5 µm
