2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 6644, Flowing cereals and milled cereal products — Automatic sampling by mechanical means (ISO 6644:2002) EN ISO 13690, Cereals, pulses and milled products — Sampling of static batches (ISO 13690:1999) prEN ISO 24333, Cereals and cereal products — Sampling (ISO/DIS 24333:2006) ISO 5223, Test sieves for cereals 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 Besatz all matter of a sample of grain other than the basic cereal of unimpaired quality NOTE 1 It comprises the four fractions: broken grains, grain impurities, sprouted grains and miscellaneous impurities. NOTE 2 Live pests are not considered as Besatz. They are specified as a separate criterion. NOTE 3 A schematic summary on Besatz is given in Annex A. NOTE 4 Pictures of examples are given in [9]. 3.2 broken grains all grains belonging to the basic cereal not damaged by pests and whose endosperm is partially uncovered, including grains damaged by threshing and grains from which the germ has been removed !3.3 grain impurities fraction consisting of shrivelled grains, other cereals, grains damaged by pests, grains in which the germ is discoloured (only for common and durum wheat), mottled grains (only for durum wheat) and grains overheated during drying Note 1 to entry: For common wheat, grains in which the germ is discoloured are disregarded up to 8 %."

2,0 mm durum wheat
1,9 mm rye
1,8 mm feed barley
2,2 mm feed barley with moisture content below 12,5% 2,0 mm and grains damaged by frost and unripe grains (green) NOTE Frost damaged kernels can show the following appearance: black or brown discoloration, bleached or blistered, distinctly wax-like or candied surface. Frequently they have dark stripes showing through the sides of the kernel. !3.3.2 other cereals all cereals grains, whatever their state, not belonging to the considered species 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 which show visible damage due to attack by insects, rodents, mites or other pests Note 1 to entry: Grains attacked by wheat midge 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. 3.3.4 grains with discoloured germ, mottled grains grains either a) with discoloured germ in which the tegument covering the germ is coloured brown to brownish black and in which the germ is normal and not sprouted; Note 1 to entry: If the germ is coloured only with one little spot, the grain is considered sound. Note 2 to entry: This fraction only exists for common wheat and durum wheat. Note 3 to entry: For common wheat these grains are disregarded up to 8 %. or b) mottled which show a brown to brownish black discoloration elsewhere than on the germ itself, particularly in the crease Note 4 to entry: If the coloration is only in the crease, grains are considered mottled only if the spot covers more than 1/4 of the length of the crease. Note 5 to entry: This fraction only exists for durum wheat." SIST EN 15587:2009+A1:2013
(synonymous: Schwarzbesatz)=fraction consisting of extraneous seeds, unsound grains, extraneous matter, husks, ergot, bunted grains and impurities of animal origin" 3.5.1 extraneous seeds seeds of plants, whether or not cultivated, other than cereals NOTE 1 They comprise noxious and not noxious seeds. Noxious seeds means seeds which are toxic to humans and animals. This group also includes seeds hampering or complicating the cleaning and milling of cereals and seeds affecting the quality of products processed from cereals. NOTE 2 In some cases it may be necessary to distinguish between noxious seeds and not noxious seeds. An indicative list of noxious seeds is given in Annex A of ISO 7970:2000 [4]. !3.5.2 unsound grains grains of the species or another cereal rendered unfit for human consumption and, regarding feed grain, for feed consumption, owing to putrefaction, mildew, grains affected with fungi (such as fusarium), bacterial or other causes Note 1 to entry: Unsound grains also include grains damaged by spontaneous heat generation or too extreme heating during drying which are fully grown grains in which the tegument is coloured greyish-brown to black while the cross-section of the kernel is coloured-yellowish grey to brownish-black. Note 2 to entry: Grains attacked by wheat midge are considered unsound grains 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 need to be classed with grains damaged by pests. Note 3 to entry: Grains affected with fusariosis are grains whose pericarp is contaminated with Fusarium mycelium; such grains look often slightly shrivelled, wrinkled and have pink or white diffuse patches with an ill-defined outline. Grains affected by fusariosis are the major source of mycotoxins. SIST EN 15587:2009+A1:2013
