10. Test Sieving according to ISO 2591-1

During the sieve analysis, a certain quantity of the test product 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 sheets.
 DIN 66 165, part 1 - Basic standard - edition 1987
 DIN 66 165, part 2 - Execution - edition 1987
These sheets are available at the Beuth-Verlag, Berlin.

10.1. 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.
