Test Sieving according to ISO 2591-1

During the sieve analysis, a certain quantity of the material is divided into fractions by one or several test
sieves. The difficulty of the sieve analysis is to determine the separation limit of the separation procedure
which is carried out by sieving. It is therefore recommended to determine the analytical separation limit.
Details of the basic principals for sieve analysis are included in the standard sheet
These sheets are available at the Beuth-Verlag, Berlin.
8.1

Largest particle to be permitted on a test sieve

To avoid damage to the test sieve, the size of the largest particle in the charge should not exceed
0,7
10w mm, where w is the nominal aperture width in mm.
