Leather - Chemical tests - Determination of water-soluble matter, water-soluble inorganic matter and water-soluble organic matter (ISO 4098:2006)
ISO 4098:2006 specifies a method of determination of water-soluble matter, water-soluble inorganic matter and water-soluble organic matter. It is applicable to all leather types.
Leder - Chemische Prüfungen - Bestimmung wasserlöslicher Substanzen, wasserlöslicher anorganischer Substanzen und wasserlöslicher organischer Substanzen (ISO 4098:2006)
Diese Internationale Norm legt ein Verfahren zur Bestimmung wasserlöslicher Substanzen, wasserlöslicher anorganischer Substanzen und wasserlöslicher organischer Substanzen fest.
Dieses Verfahren gilt für alle Lederarten. Das durch diese Untersuchung erhaltene Ergebnis hängt von Faktoren ab, wie zum Beispiel:
- dem Grad, bis zu dem das Leder zerkleinert wird;
- der Extraktionstemperatur;
- der Extraktionsdauer;
- dem Leder-Wasser-Verhältnis.
Zum Erhalt vergleichbarer Ergebnisse ist es folglich zwingend erforderlich, dass die Bedingungen stets genau gleich sind.
In jedem Fall werden in dem Filtrat vorhandene Ammoniumsalze als Teil der wasserlöslichen Substanz einbezogen und anschließend beim Glühen zersetzt. Auf diese Weise tragen sie zum Ergebnis der wasserlöslichen organischen Substanzen bei. Die Konzentration an Ammoniumsalzen kann, sofern gefordert, in dem Filtrat getrennt bestimmt werden.

L'ISO 4098:2006 spécifie une méthode de détermination des matières solubles dans l'eau, des matières inorganiques solubles dans l'eau et des matières organiques solubles dans l'eau. Elle s'applique à tous les types de cuir.

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 4098 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 289, Leather, in collaboration with the Chemical Tests Commission of the International Union of
Leather Technologists and Chemists Societies (IUC Commission, IULTCS), in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna Agreement). It is based
