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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
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 13690 was prepared by Technical Committee ISO/TC 34, Agricultural food products,
Subcommittee SC 4, Cereals and pulses.
This first edition of ISO 13690 cancels and replaces ISO 950:1979, ISO 951:1979 and ISO 2170:1980.
Annex A forms a normative part of this International Standard. Annexes B and C are for information only.

Introduction
Correct sampling is an operation that requires the most careful attention. Emphasis cannot, therefore, be too
strongly laid on the necessity of obtaining a properly representative sample of cereals, pulses and milled products.
Accurate analytical work and the interpretation of results are wasted if the sample does not accurately represent the
lot from which is taken.
The procedures given in this International Standard are recognized as good practice and it is strongly
recommended that they be followed whenever practicable. It is recognised that it is difficult to lay down fixed rules to
be followed in every case, and particular circumstances may render some modification of the method desirable, for
example if it is desired to check the uniformity of a consignment by the examination of individual increments.
In certain areas there are widely recognized trade associations which specify rules for the sampling procedures to
be used in contracts under their auspices. In no case will this International Standard override the rules laid down in
such contracts.
It is highly desirable that personnel employed in sampling should have been suitably trained.

INTERNATIONAL STANDARD  © ISO ISO 13690:1999(E)
Cereals, pulses and milled products — Sampling of static batches
1 Scope
This International Standard specifies general conditions relating to sampling for the assessment of the quality of
cereals, pulses and milled products from cereals and pulses (hereinafter called "grain"), in bulk or in bags, but
excluding pellets.
It is applicable to the manual or mechanical sampling of static bulk grain up to a depth of 3 m. For static bulks
exceeding 3 m in depth up to a maximum depth of 12 m, it is necessary to use mechanical sampling methods. For
bulk grain exceeding 12 m in depth it is necessary to sample grain when flowing. This latter sampling method is also
applicable for all depths of bulk grain (see ISO 6644).
This International Standard is not applicable to seed grain, nor does it apply to sampling for testing for hidden
infestation. It is not applicable to flowing grain.
This International Standard is not applicable for certain sampling requirements (e.g. microbiological, mycotoxin and
pesticide residue analysis). In these cases, it is recommended that the parties concerned come to an agreement.
NOTE 1 Sampling of seed grain is covered by rules established by the International Seed Testing Association.
NOTE 2 Sampling for hidden insect infestation is covered by ISO 6639-2.
NOTE 3 ISO 6644 covers sampling of flowing grain.
2 Terms and definitions
For the purposes of this International Standard, the following terms and definitions apply.
2.1
consignment
physical quantity of grain on offer, dispatched or received at one time, and covered by a particular contract or
shipping document; it may be composed of one or more lots
NOTE Consignments should be considered in lots not exceeding 500 t.
2.2
lot
stated portion of the consignment whose quality is to be assessed
2.3
increment
small equal quantity of grain taken from each individual sampling point in the lot, throughout the full depth of the lot
2.4
laden
term to describe a partly or completely full state, as for wagon, lorry, barge or ship
NOTE See 6.3.1.
2.5
bulk sample
quantity of grain obtained by combining and mixing the increments taken from a specific lot
© ISO
ISO 13690:1999(E)
2.6
laboratory sample
quantity of grain removed from the bulk sample and intended for analysis or other examination
3 General principles
3.1  Samples should be taken jointly by representatives of the buyer and seller or by a sampling superintendent
appointed jointly.
Samples shall be as representative as possible of the lots from which they are taken. Therefore, as the
3.2
composition of a lot is seldom uniform, a sufficient number of increments shall be taken and carefully mixed, thus
giving a bulk sample from which the laboratory samples (see 8.3) are obtained by successive divisions or otherwise.
NOTE A sampling scheme for consignments of more than 100 bags is given in annex A.
3.3  It is normal practice that grain which is sea-damaged or otherwise damaged in transit, or is out of condition, is
kept separate from the sound grain and is sampled separately. Samples of unsound material shall not be mixed with
samples of sound material and shall be identified and quantified (see clause 11).
3.4  Special care is necessary to ensure that all sampling apparatus is clean, dry and free from foreign odours.
3.5  Sampling shall be carried out in such a manner as to protect the samples, sampling instruments, and the
containers in which the samples are placed, from contamination from rain, dust, etc. If walking on grain cannot be
avoided, precautions in the form of protective clothing should be taken to prevent contamination of the grain.
4 Instruments
4.1 General
Many different types of instrument are available. Those given in annex B and their dimensions are included,
therefore, solely as a guide. Annex C is included to help in the selection of suitable sampling instruments. It is
known that use of the various types of equipment can give rise to differing samples from the same lot.
Where possible, the type of equipment to be used and the procedures for its use shall be determined by agreement
between the parties concerned.
The instruments listed in 4.2 to 4.4 are in general usage.
Pneumatic samplers should not be used for milled products.
All instruments used shall be suitable for the product being sampled.
4.2 Sampling from bulk
Use appropriate apparatus for obtaining increments from static bulk (e.g. hand-held spears, mechanical or air-
assisted apparatus).
4.3 Sampling from bags
Use sack-type spears.
4.4 Mixing and dividing
Use shovels and dividing apparatus or automatic random dividing apparatus.
5 Location and time of sampling
The location and time of sampling shall be determined by agreement between the parties concerned.
