Oilseed impurities are separated in the method by sieving and sorting, into three categories: fines, non-­oleaginous impurities, and oleaginous impurities. The mass of total impurities is determined or, on request, the mass of each category of impurity. Impurities in oilseeds refers to all foreign matter, organic and inorganic, other than seeds of the species under consideration. Fines in oilseeds is defined as particles passing through the sieves of aperture sizes given in Table 1, according to the species being analyzed. This method determines the impurities content in oilseeds used as primary industrial materials. It also defines the various categories of what are usually understood to be impurities.
