Results and discussion

Mass median aerodynamic diameter:
32.9 µm
Particle size
Percentile:
D50
Mean:
< 32.9 µm
St. dev.:
0.926
Remarks on result:
other: The mass median diameter of the test item indicates that 50 % of the particles are smaller than 32.9 μm

Any other information on results incl. tables

The standard deviation is smaller than 5 %, therefore the study is considered to be valid and no further testing is necessary. The particle size distribution was found to be in the range from approximately 0.3 μm to 150 μm.

Applicant's summary and conclusion

Conclusions:
The mass median diameter (MMD) was determined to be 32.9 μm.
