    1,80 mm x 20,0 mm

    1,90 mm x 20,0 mm

    2,00 mm x 20,0 mm

    2,20 mm x 20,0 mm

    2,50 mm x 20,0 mm

Test sieves with long rounded apertures listed in a) are used in particular for separating “shrivelled” ker­ nels from rye, durum wheat, common wheat and barley, with the exception of those with apertures of diameters 2,50 mm and 2,80 mm, which are usually used for the calibration of malting barley.

Test sieves with round apertures of diameter 4,50 mm are used for separating broken grains from maize.
