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.
The main task of technical committees is to prepare International Standards. 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 identiying any or all such patent rights.
ISO 5984 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 10, Animal feeding
stuffs.
This second edition cancels and replaces the first edition (ISO 5984:1978), of which it constitutes a minor revision.
Annex A of this International Standard is for information only.

INTERNATIONAL STANDARD ISO 5984:2002(E)
Animal feeding stuffs — Determination of crude ash
1 Scope
This International Standard specifies a method for the determination of crude ash of animal feeding stuffs.
2 Normative reference
The following normative document contains provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent edition of the normative document indicated below. For

ISO 6498, Animal feeding stuffs — Preparation of test samples
3 Term and definition
For the purposes of this International Standard, the following term and definition applies.
3.1
crude ash
residue obtained after incineration at 550 °C under the conditions specified in this International Standard
NOTE It is expressed as a mass fraction of the sample in percent.
4 Principle
The organic matter in a test portion is decomposed by incineration, then the ash obtained is weighed.
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 Muffle furnace, electrically heated, thermostatically controlled, and provided with a pyrometer.
The furnace, when set at 550 °C, shall be capable of being controlled in such a way that the temperature in the
places where the incineration dishes will be placed will not differ by more than 20 °C from this set temperature.
5.3 Drying oven, capable of being controlled at (103 ± 2) °C.
5.4 Hot-plate or gas burner

by the conditions of the test, preferably rectangular with a surface area of about 20 cm and a height of about
2,5 cm.
2
For samples that are inclined to swell on carbonization, use dishes with a surface area of about 30 cm and a
height of about 3 cm.
5.6 Desiccator, provided with an effective desiccant.
6 Sampling
It is important that the laboratory receive a sample which is truly representative and has not been damaged or
changed during transport or storage.
Store the sample in such a way that deterioration and change in composition are prevented.
Sampling is not part of the method specifie
