- Conclusions:
- Granules of the test item are not smaller than 0.1 mm. The majority of granules are 0.2 - 1 mm (96 %).
- Executive summary:
The particle size distribution of the test substance was determined according to PN-EN 1235:1999/A1:2004.
The dry sieving test of FeIDHA was performed as following: about 100 g of the tested material was material was weighted to the nearest 0,01 g and transferred quantitatively to a tarred clean, dry of 1 mm aperture sieve. It was the upper sieve of a set of 1 mm, 0,8 mm, 0,7 mm, 0,5 mm, 0,4 mm, 0,3 mm, 0,2 mm, 0,1 mm sieves. The sieving was carried out using apparatus at an amplitude of250 revolutions per minute during 10 minutes.After the completion of the sieving process the sieves were checked for the proper fractions.
Granules of the test item are not smaller than 0.1 mm. The majority of granules are 0.2 - 1 mm (96 %).

Description of key information
Granules of the test item are not smaller than 0.1 mm. The majority of granules are
0.2 - 1 mm (96 %).
Additional information
After the completion of the sieving process according to PN-EN 1235:1999/A1:2004, the particle size distribution at different passages was determined. The majority of granules are 0.32 - 0.500 mm (96%).
