标准摘要
[中文适用范围]: 本国际标准规定了一种参考方法,用于测定用作工业原料的油籽的己烷提取物(或轻质石油提取物),称为“含油量”。向日葵种子的程序与其他种子不同,因为它包括在将种子研磨成试验样品后测定水分含量。该方法已在油菜籽、大豆和向日葵种子上进行了测试。但这并不排除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(见9.4)。对于花生(见10.1.6),可以分别分析纯种子、总细粒、非油质杂质和油质杂质。 [外文原描述]: 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.
