Any other information on results incl. tables

The inhalable fraction is defined as the mass fraction of particles which can be inhaled by nose or mouth, the thoracic fraction is defined as the mass fraction of particles that passes the larynx and the respirable fraction is defined as the mass fraction of particles that reaches the alveoli.

 Measurement  Method  Result
 Percentage of test item with an inhalable particle size <100 µm  Sieve  50.5%
 Percentage of test item with a thoracic particle size <10.0 µm  Cascade Impactor  0.38%
 Percentage of test item with a respirable particle size <5.5 µm  Cascade Impactor  0.08%

Applicant's summary and conclusion

Conclusions:
Particle size data acquired for the test item is shown in the following table:
 Percentage of test item with an inhalable particle size <100 µm : (Sieve)  50.5%
 Percentage of test item with a thoracic particle size <10.0 µm  (Cascade Impactor)  0.38%
 Percentage of test item with a respirable particle size <5.5 µm  (Cascade Impactor)  0.08%
Executive summary:

Particle size data was acquired using a procedure designed to be compatible with the European Commission Technical Guidance Document EUR 20268 ‘Determination of Particle Size Distribution, Fibre Length and Diameter Distribution of Chemical Substances (2002)’. Too few particles were of a size less than 10.0 µm to allow accurate assessment of the mass median aerodynamic diameter.

Particle size data acquired for the test item is shown in the following table:

 Percentage of test item with an inhalable particle size <100 µm : (Sieve)  50.5%

 Percentage of test item with a thoracic particle size <10.0 µm  (Cascade Impactor)  0.38%

 Percentage of test item with a respirable particle size <5.5 µm  (Cascade Impactor)  0.08%
