Given standard deviation is based on the general experience with the method. The estimated values are typical standard deviations:

D10: 4 % of D10 (minimum value 0.05 µm)

D50: 13 % of D50 (minimum value 0.1 µm)

D90: 29 % of D90 - D50

Description of key information

D10: 10 µm

D50: 117 µm

D90: 537 µm
