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 2.
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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 663 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 11, Animal and
vegetable fats and oils.
This fourth edition cancels and replaces the third edition (ISO 663:2000), which has been technically revised.

INTERNATIONAL STANDARD ISO 663:2007(E)

Animal and vegetable fats and oils — Determination of
insoluble impurities content
1 Scope
This International Standard specifies a method for the determination of the insoluble impurities content of
animal and vegetable fats and oils.
If it is not desired to include soaps (particularly calcium soaps) or oxidized fatty acids in the insoluble
impurities content, it is necessary to use a different solvent and procedure. In this case, an agreement is to be
reached between the parties concerned.
2 Normative reference
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
