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.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 6644 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee
SC 4, Cereals and pulses.
This second edition cancels and replaces the first edition (ISO 6644:1981), which has been technically revised.
Annex A of this International Standard is for information only.

Introduction
Correct sampling is an operation that requires most careful attention. Therefore emphasis cannot be too strongly laid
on the necessity of obtaining a properly representative sample of cereal grain or milled product. Careless or
inaccurate sampling could lead to misunderstanding and to unwarranted financial adjustment.
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 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, determination of
qualitative factors, such as moisture content, is best achieved by examination of the laboratory sample, whereas a
quantitative factor, such as detection of insects, is best achieved by examination of individual increments.
