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