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 5985 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 5985:1978), of which it constitutes a minor revision.
Annex A of this International Standard is for information only.

INTERNATIONAL STANDARD ISO 5985:2002(E)

Animal feeding stuffs — Determination of ash insoluble
in hydrochloric acid
1 Scope
This International Standard specifies two procedures for animal feeding stuffs for the determination of the ash
which is insoluble in hydrochloric acid.
The applicable procedure depends on the nature of the sample.
a) Procedure A is applicable to simple organic animal feeding stuffs and to compound feeding stuffs (except
those mentioned under procedure B).
b) Procedure B is applicable to minerals, mineral mixtures and compound feeding stuffs of which the ash
insoluble in hydrochloric acid exceeds 1 % (mass fraction), as determined by procedure A.
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
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.
