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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent
rights identified during the development of the document will be in the Introduction and/or on the ISO list of
patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical ISO/TC 34, Food products, Subcommittee SC 2, Oleaginous seeds and
fruits and oilseed meals.
This third edition cancels and replaces the second edition (ISO 10565:1998), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— Clarification of the scope;
— Addition of additional information in the protocol.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

Oilseeds — Simultaneous determination of oil and water
contents — Method using pulsed nuclear magnetic resonance
spectrometry
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 co
