标准范围

ISO 659:2009规定了测定用作工业原料的油籽己烷提取物（或轻石油提取物）的参考方法，称为“含油量”。向日葵种子的程序不同于其他种子的程序，因为它包括在种子研磨以制备测试样品后额外测定水分含量。该方法已在油菜籽、大豆和葵花籽上进行了试验。然而，这并不妨碍其适用于其他商业种子。如果需要，可以分别分析纯种子和杂质。对于花生，可以分别分析纯种子、总细粒、非含油杂质和含油杂质。

ISO 659:2009 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 can be analysed separately. In the case of groundnuts, the pure seeds, the total fines, the non-oleaginous impurities and the oleaginous impurities can be analysed separately.
