Oilseeds - Determination of oil content - Method using continuous-wave low-resolution nuclear magnetic resonance spectrometry (Rapid method) (ISO 5511:1992)

Under normal conditions of use, it does not apply to oilseeds which do not yield oil which is completely liquid at 20 °C (e.g. shea, palm, illipe, cocoa, etc.). The method has been successfully tested on the following oilseeds: rapeseed, soya, sunflower seed and groundnuts. The reference method for the determination of the oil content of oilseeds is specified in ISO 659.

Ölsamen - Bestimmung des Ölgehaltes - Kernresonanzspektroskopie mit niedriger Auflösung (Schnellverfahren) (ISO 5511:1992)

Diese Internationale Norm legt ein Schnellverfahren zur Bestimmung des Ölgehalts von Ölsamen unter Anwendung der magnetischen Kernresonanzspektroskopie mit niedriger Auflösung fest. Unter üblichen Anwendungsbedingungen gilt es nicht für Ölsamen, deren Ölgehalt bei 20 °C nicht vollständig flüssig ist (z.B. Sheafett, Palmöl, Illipefett, Kakaobutter usw.). Erfolgreich geprüft wurde dieses Verfahren an Rapssamen, Soja, Sonnenblumenkernen und Erdnüssen.

Graines oléagineuses - Détermination de la teneur en huile - Méthode par spectrométrie de résonance magnétique nucléaire a basse résolution et a onde continue (Méthode rapide) (ISO 5511:1992)

La présente Norme internationale prescrit une méthode rapide de détermination de la teneur en huile des graines oléagineuses, par spectrométrie de résonance magnétique nucléaire à basse résolution et à onde continue. Elle ne s'applique pas, dans les conditions usuelles d'emploi, aux graines oléagineuses ne donnant pas une huile entièrement liquide à 20 °C (karité, palmiste, illipé, cacao, etc.). La présente méthode a été expérimentée avec succès sur les graines oléagineuses suivantes: colza, soja, tournesol et arachide.
NOTE 1 La détermination de la teneur en huile des graines oléagineuses fait l'objet d'une méthode de référence spécifiée dans l'ISO 659.

Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national Standards bodies (ISO member bodies). The work
of preparing International Standards is normally carried out through ISO
technical committees. Esch member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, govern-
mentai and non-governmental, in liaison with ISO, also take part in the
work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an lnter-
national Standard requires approval by at least 75 % of the member
bodies casting a vote.
International Standard ISO 5511 was prepared by Technical Committee
ISO/TC 34, Agricultural food products, Sub-Committee SC 2, Oleaginous
seeds and fruits.
This second edition cancels and replaces the first edition
(ISO 5511:1984), of which it constitutes a technical revision.
