The test item EVANSTAB® 12/18 consists of a coarse fraction with particle sizes of >2000 µm of 92.6 % and a fine fraction with particle sizes of <2000 µm of 7.4%. The fine fraction of the test item has a median particle size D50 = 769 µm, which was determined by laser diffraction measurement.

Conclusions:
The test item EVANSTAB®12/18 consists of a coarse fraction with particle sizes of >2000 µm of 92.6% and a fine fraction with particle sizes of <2000 µm of 7.4%. The fine fraction of the test item has a median particle size D50 = 769 µm, which was determined by laser diffraction measurement.
Executive summary:

The test item EVANSTAB® 12/18 consists of a coarse fraction with particle sizes of >2000 µm of 92.6% and a fine fraction with particle sizes of <2000 µm of 7.4%. The fine fraction of the test item has a median particle size D50 = 769 µm, which was determined by laser diffraction measurement.
