This International Standard specifies a reference method for the determination of the hexane extract (or light petroleum extract), called "oil content", of oil seeds used as industrial raw materials.
NOTE If required, the following may be analysed separately:
- the pure seeds and the impurities (see 9.3);
- in the case of groundnuts, the pure seeds, the total fines, the non-oleaginous impurities and the oleaginous impurities.
The method has been tested on rapeseed, soya beans and sunflower seeds. This does not, however, preclude its applicability to other commercial seeds.
