Oilseeds - Determination of oil content (Reference method)

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.

Oilseeds. Determination of oil content (reference method).

La présente Norme internationale spécifie une méthode de référence pour la détermination de l'extrait à l'hexane (ou à l'éther de pétrole), dit "teneur en huile", des graines oléagineuses utilisées comme matière première industrielle. NOTE Sur demande, on peut analyser séparément: les graines pures et les impuretés (voir 9.3); les graines pures, les poussières totales, les impuretés non oléagineuses et oléagineuses, dans le cas de l'arachide. La méthode a été essayée sur des graines de colza, de soja et de tournesol. Ceci n'exclut, toutefois, la possibilité d'appliquer cette méthode à d'autres graines disponibles dans le commerce.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
