Conclusions:
In a sief test performed according to ASTM D1921, the particle size of Potassium ferricyanide was determined to be ≥ 0.15 mm. Particle sizes were distributed as follows: 43.4% ≥0.6 mm, 36.9% ≥0.4 mm and 19.3% ≥0.2 mm.

Description of key information

In a sieve test performed according to ASTM D1921 using a Retsch AS200 sieve shaker, the particle size of Potassium ferricyanide was determined to be ≥ 0.15 mm. Particle sizes were distributed as follows: 43.4% ≥0.6 mm, 36.9% ≥0.4 mm and 19.3% ≥0.2 mm.

Additional information

The particle size of the substance is high. Particles < 100 µm which have the potential to be inhaled, are not present.
