scope:

This International Standard specifies a reference method for the determination of the hexane extract (or light petroleum extract), called "oil content", of oilseeds used as industrial raw materials. The procedure for sunflower seeds is different from the other seeds as it includes a second moisture content determination after the first mechanical grind. The method has been tested on rapeseed, soya beans and sunflower seeds. This does not, however, preclude its applicability to other commercial seeds. If required, the pure seeds and the impurities (see 9.4) may be analysed separately. In the case of groundnuts, the pure seeds, the total fines, the non-oleaginous impurities and the oleaginous impurities (see 10.1.6) may be analysed separately.
