Description of key information

The mean particle size of the milled test item (milled press cake for testing purposes) was determined to be 6.4 µm with a 90% range of 2.4 to 15.8 µm; whereas the mean particle size of the imported and marketed product is determined to be 150.8 µm with a 90% range of 56.35 to 245 µm.

Additional information

The test item is part of the Dianix XF2 series. A one of the components of this series, the particle size of the dedusted dye product of Disperse Blue CVG, which is part of the dye product of the test item as imported and marketed, was determined at its production site by laser diffraction (light scattering).

The median particle size L50 (D (v, 0.5): 50 % of particle volume or particle mass with lower particle diameter) deduced from these distributions are: L50 = 150.8 µm

The particle size L10 (D (v, 0.1): 10 % of particle volume or particle mass with lower particle diameter) deduced from these distributions are: L10 = 56.35 µm

The particle size L90 (D (v, 0.9): 90 % of particle volume or particle mass with lower particle diameter) deduced from these distributions are: L90 = 245 µm

The particle size distribution of the test item that was milled for testing purposes was determined by laser diffraction (light scattering).

The median particle size L50 of the test item deduced from the particle size distributions was 6.4 µm.

The particle size L10 of the test item deduced from the particle size distributions was 2.4 µm.

The particle size L90 of the test item deduced from the particle size distributions was 15.8 µm.
