Sieve Screening Test
The results of the sieving procedure are shown in the following table:
Mass of test item transferred to sieve (W1)
Mass of test item passed through sieve (W3 – W2)
Percentage of test item less than 100 μm
Too few particles were of a size less than 10.0 μm to allow accurate assessment of the mass median aerodynamic diameter.
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.
The particle size distribution was determined by a seive method 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), in accordance with GLP.
There were too few particles of a size less than 10.0 μm to allow for an accurate assessment of the mass median aerodynamic diameter.
As percentage of test item having an inhalable particle size of less than 100 μm was determined to be 1.29%. The test item has been considered to be essentially non-inhalable.
