Physical tests including the sieving test, thousand kernel weight and hectoliter weight are a part of the barley analysis required by the German Bundessortenamt (federal authority responsible for varieties and seed affairs) for the evaluation of new malting barley varieties.
This method describes how to classify barley according to size using a laboratory sieving machine.
Barley intended for the production of malt is to be evaluated on the basis of the characteristics described below.
A barley sample is classified into fractions according to kernel size in a sieving machine containing three sieves with defined slot widths.
