Oilseeds - Simultaneous determination of oil and water contents - Method using pulsed nuclear magnetic resonance spectrometry (ISO 10565:1998)
This International Standard specifies a rapid method for the determination of the oil and water contents of commercial oilseeds using pulsed nuclear magnetic resonance (NMR). It is applicable to rapeseeds, soya beans, linseeds and sunflower seeds with a water content less than 10 %. For seeds with higher water contents, drying is necessary before the oil content can be determined by pulsed NMR. NOTE 1 This method has been tested with rapeseeds, soya beans, linseeds and sunflower seeds. This does not, however, preclude its applicability to other commercial seeds whose oil is liquid at the temperature of measurement. NOTE 2 The reproducibility values are generally higher than those obtained by the drying method (ISO 665)
Ölsamen - Gleichzeitige Bestimmung des Öl- und Wassergehaltes - Verfahren mit gepulster Kernresonanzspektroskopie (ISO 10565:1998)
Diese Internationale Norm legt ein Schnellverfahren zur Bestimmung des Öl- und Wassergehalts handelsüblicher Ölsamen mit gepulster Kernresonanzspektrometrie (NMR) fest. Es ist bei Rapssamen, Sojabohnen, Leinsamen und Sonnenblumensamen mit einem Wassergehalt unter 10% anwendbar. Samen mit höherem Wassergehalt müssen getrocknet werden, bevor die Bestimmung des Ölgehaltes mit gepulster NMR durchgeführt wird.
Graines oléagineuses - Détermination simultanée de la teneur en huile et en eau - Méthode par spectrométrie par résonance magnétique nucléaire pulsée (ISO 10565:1998)
La présente Norme internationale spécifie une méthode de détermination rapide de la teneur en huile et en eau dans les graines entières du commerce, par spectrométrie par résonance magnétique nucléaire (RMN) pulsée. Elle est applicable aux graines de colza, de soja, de lin et de tournesol dont la teneur en eau est inférieure à 10 %. Pour des graines ayant des teneurs en eau plus élevées, il est nécessaire de les sécher avant de déterminer leur teneur en huile par RMN pulsée. NOTE 1 Cette méthode a été expérimentée sur les graines de colza, de soja, de lin et de tournesol. Cela n'exclut toutefois pas qu'elle puisse s'appliquer également à d'autres graines oléagineuses du commerce dont l'huile est liquide à la température de mesurage. NOTE 2 Les valeurs de reproductibilité obtenues sont généralement plus élevées que celles obtenues par la méthode par dessiccation (ISO 665).

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. Each 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, governmental 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 International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 10565 was prepared by Technical Committee
ISO/TC 34, Agricultural food products, Subcommittee SC 2, Oleaginous
seeds and fruits.
This second edition cancels and replaces the first edition
(ISO 10565:1993), which has been technically revised.
Annexes A and B of this International Standard are for information only.

1 Scope
This International Standard specifies a rapid method for the determination of the oil and water contents of
commercial oilseeds using pulsed nuclear magnetic resonance (NMR).
It is applicable to rapeseeds, soya beans, linseeds and sunflower seeds with a water content less than 10 %. For
seeds with higher water contents, drying is necessary before the oil content can be determined by pulsed NMR.
NOTE 1 This method has been tested with rapeseeds, soya beans, linseeds and sunflower seeds. This does not, however,
preclude its applicability to other commercial seeds whose oil is liquid at the temperature of measurement.
NOTE 2 The reproducibility values are generally higher than those obtained by the drying method (ISO 665).
