EC number: 701-326-2 | CAS number: -
In individual measurements, a 100% cumulative retained was found respectively on mesh of 315, 250, 125, 75 and 75 µm.
From the average distribution above, 99.9% of particles are above 100 µm, and no particles are smaller than 63 µm.
Particle size distribution of the test substance was determined by sieving on a column with 9 mesh sizes from 1000 to 63 µm.
Five replicates were conducted, and the average distribution was reported.
With regard to inhalation potential, 99.9% of particles are larger than 100 μm, and no particles are smaller than 63 µm, therefore can't reach the thoracic fraction.
Fine particles relevant to dust explosion hazard (<630 μm) are less than 2%.
The substance contains no inhable particle (99.9% larger than 100 µm).
An experimental study is available. Despite restrictions as not related to a guideline, it is considered reliable and sufficient for purpose, and therefore a key study.
