The test item was sieved with a mesh size of 1000 µm. 76.2% (w/w) of the test item passed the sieve and only this fraction was measured with laser diffraction. Median particle size: 405.7 µm. L10 was 66.9 µm and L90 was 820.3 µm.

Description of key information

Median particle size: 405.7 µm. L10 was 66.9 µm and L90 was 820.3 µm.
