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/

This document was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee
SC 2, Oleaginous seeds and fruits and oilseed meals, in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 307, Oilseeds, vegetable and animal fats and oils and
their by-products — Methods of sampling and analysis, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 665:2000), of which it constitutes a
minor revision. The changes compared with the previous edition are as follows:
— the date of the normative reference ISO 664 has been deleted;
— ISO 542 has been replaced by ISO 21294 and thus the reference in this document has been updated
accordingly.
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.

INTERNATIONAL STANDARD ISO 665:2020(E)
Oilseeds — Determination of moisture and volatile
matter content
1 Scope
This document specifies a method for the determination of the moisture and volatile matter content of
oilseeds.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
ISO 664, Oilseeds — Reduction of laboratory sample to test sample
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at http:// www .electropedia .org/
3.1
moisture and volatile matter content
loss in mass measured under the operating conditions specified in this document
Note 1 to entry: It is expressed as a mass fraction, in per cent [formerly given as % (mass fraction)] of the mass of
the initial sample.
4 Principle
The moisture and volatile matter content of a test portion is determined, either on the material as
received (pure seed and impurities) or, if required, on the pure seed alone, by drying at 103 °C ± 2 °C in
an oven at atmospheric pressure, until practically constant mass is reached.
5 Apparatus
Usual laboratory apparatus and, in particular, the following.
5.1 Analytical balance, capable of weighing to the nearest 0,001 g.
5.2 Mechanical mill, easy to clean, suitable for the kind of seed and allowing the latter to be ground
without heating and without appreciable change in moi
