Description of key information

MMD < 450 µm

Additional information

The particle size distribution of the test item was determined in an experimental study using sieving and a multistage impactor according to the OECD Guideline 110 (1981). The sieve sizes used in the test were 2000, 1000, 500, 200, 100 and 63 µm. The sizes measured in the multistage impactor were 63, 26.19, 12.77, 6.57, 3.28, 1.65, 0.80 and 0.38 µm.
