Results
The dry sieving test of FeHBED 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 2 mm, 1,5 mm, 1,0 mm, 0,3 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.
Calculation: The percentage of material captured at each sieve was calculated using the following equation:
xn= mn/mtx 100
where:
xn– percentage of solid remaining at a sieve,
mn– weight of the fraction (in grams),
mt– total weight of tested sample used (in grams, mt= m0+ m1+…mj)
Description of key information
The particle size distribution of the test substance was determined in a non-GLP study (2012) according to method PN-EN 1235:1999/A1:2004 by using the dry sieve test.
Results:
<0.1 mm: 0%
<0.3 mm: 5%
<1 mm: 50%
<1.5 mm: 70%
<2 mm: 85%
Additional information
No particles under 100 µm
