Note 1 to entry: In a durum wheat sample, all common wheat grains and their grain dockage components are classified as other cereals and vice versa. 3.3.3 grains damaged by pests grains or part of grains belonging to the basic cereal which show visible damage due to attack by insects, rodents, mites or other pests Note 1 to entry: Grains attacked by wheat midge (Sitodiplosis mosellana) are considered unsound grains (3.5.2) only when more than half the surface of the back of the grain is coloured grey to black as a result of secondary cryptogamic attack. Where discoloration covers less than half the surface of the back of the grain, they are classed as grains damaged by pests. Note 2 to entry:
Grains attacked by bug (Eurygaster integriceps, Eurygaster maura) are considered damaged by pest when they present a brighter spot with a more or less visible coloured point in the centre representing the scar of the bite. This spot often wrinkled, is of less consistency that the rest of the grain. SIST EN 15587:2019

stones, mud balls, straws, chaff and similar impurities from the overtails of the 1,0 mm slotted sieve (5.3).are weighted together to the nearest 0,01 g and are regarded as extraneous matter (3.5.3). Impurities of animal origin should be counted, including those which passed through the sieve of 1,0 mm slotwidth (5.3). If necessary, a magnifying glass (5.5) should be used. The count should be quoted separately in numbers per kg of common wheat, durum wheat, rye, triticale or feed barley as appropriate. The remaining fraction retained by the 1,0 mm slotted sieve, added with other cereals, untreshed grains and particularly large grains of the basic cereal retained by the 3,55 mm slotted sieve previously isolated, is divided with the sample divider (5.1) to obtain a sub sample (c) between 50 g and 100 g. Weigh it to the nearest 0,1 g. This partial sample is spread out on a table and fractions defined in Clause 3 are extracted by means of forceps or a horn spatula (5.6). In case multiple kinds of damages are observed, the damaged grain shall be added to the fraction with the highest importance for the overall quality (according to Annex B). In rye samples with respect of natural variability of the colour of rye grains, grains with discoloured germ (3.3.4) are not picked out. If the partial sample contains unthreshed grains of the basic cereals, remove the grains from the glumes by hand and add them to the fraction husks (3.5.4). This sub sample without all the impurities is sieved for 30 s on a sieve (5.3) with an aperture of 2,0 mm for common wheat, 1,9 mm for durum wheat and triticale, 1,8 mm for rye, 2,2 mm for feed barley. All elements passing through are considered as shrivelled grains. Weigh the Besatz-free overtails of the 1,0 mm sieve (d) and all the groups of Besatz to the nearest 0,01 g. If, for a partial sample, the sum (s) of broken grains (3.2), shrivelled grains (3.3.1), other cereals (3.3.2), grains damaged by pests (3.3.3), grains in which the germ is discoloured (3.3.4), grains overheated during drying (3.3.5), sprouted grains (3.4), extraneous seeds (3.5.1), unsound grains (3.5.2), husks (3.5.4), bunted grains (3.5.6) and the weight of the Besatz-free overtails of the 1,0 mm sieve (d) differs by more than 0,5 % fro
