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).

Introduction
Most oilseeds are marketed on the basis of the result of analysis of the samples representing lots, and
disputes are invariably settled by reference to these samples. Careless or inaccurate sampling practices
could lead to misunderstandings, delays and unwarranted financial adjustments.
Correct sampling is a difficult process and one that requires the most careful attention. Emphasis
cannot therefore be too strongly laid on the necessity of obtaining a representative sample of oilseeds
for analysis.

Oilseeds — Manual or automatic discontinuous sampling
1 Scope
This document specifies the requirements for discontinuous sampling of oilseeds, using the manual or
automatic method, for the purpose of assessing their quality and condition.
NOTE An example of “condition” is an odour due to a treatment product.
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:
— IEC Electropedia: available at http://www.electropedia.org/
— ISO Online browsing platform: available at http://www.iso.org/obp
3.1
discontinuous sampling
sampling by automatic or manual means of at least one position within a lot (3.3) of both static and
moving oilseeds
Note 1 to entry: Manual sampling of moving oilseeds is considered discontinuous sampling.
Note 2 to entry: For comparison, continuous sampling is the automatic uninterrupted sampling of moving
oilseeds within a lot across the entire flow (for example, a permanent sampling system on a conveyor belt or any
circulation flow that enables continuous sample taking throughout the loading or discharge of the consignment;
there is no break in the sampling procedure).
EXAMPLE Hand-scoops, manual and/or automatic samplers (sequenced), shovels, suitable sampling buckets,
etc. are means of sequenced sampling and are part of discontinuous sampling.
3.2
consignment
quantity of oilseeds dispatched or received at one time and covered by a particular contract or shipping
document
Note 1 to entry: The consignment can be composed of one or more lots or part of a lot.
3.3
lot
stated quantity of the consignment (3.2) presumed to be of uniform characteristics, which can be
sampled in order to determine its quality and condition
Note 1 to entry: The quantity of the lot can be of a mass up to 5 000 t.

3.4
increment sample
amount of material taken at one time at each individual sampling point (at each individual sampling
time for moving lot) throughout a lot (3.3)
3.5
bulk sample
quantity of oilseeds obtained by combining and blending the increments taken from any one particular
lot (3.3)
3.6
homogenization
thorough blending by mechanical or manual means so that any contaminants or foreign materials are
thoroughly distributed throughout the bulk or laboratory sample (3.7)
3.7
laboratory sample
representative quantity of oilseeds obtained by homogenization (3.6) and division of the bulk sample
(3.5) and intended for analysis or other examination in a laboratory
4 Principles
4.1 Representative samples
The laboratory samples shall be as representative as possible of the lots from which they are taken.
Each consignment shall be divided, actually or notionally, into lots of 500 t to 5 000 t according to its
size. At least a minimum number of increments shall be taken from each lot and homogenized carefully
in order to obtain a bulk samp
