Leather - Chemical determination of chromic oxide content - Part 2: Quantification by colorimetric determination (ISO 5398-2:2009)
This part of ISO 5398 describes the determination of chrome by colorimetric means. It is applicable to leathers which are expected to have chromic oxide contents in excess of 0,05 %. This is an analysis for total chromium in leather; it is not compound specific or specific to its oxidation state.
Leder - Chemische Bestimmung des Chromoxidgehaltes - Teil 2: Bestimmung durch Kolorimetrie (ISO 5398-2:2009)
Dieser Teil der ISO 5398 beschreibt die Bestimmung von Chrom durch kolorimetrische Geräte und ist vorgesehen
für Leder, bei denen Chromoxidgehalte von mehr als 0,05 % vermutet werden.
Im vorliegenden Fall handelt es sich um eine Analyse des Gesamtchromgehaltes in Leder, die nicht verbindungsspezifisch
oder spezifisch für die Oxidationsstufe ist.
Cuir - Dosage de l'oxyde de chrome - Partie 2: Quantification par dosage colorimétrique (ISO 5398-2:2009)
L'ISO 5398‑2:2009 décrit le dosage du chrome par des moyens colorimétriques. Elle est applicable aux cuirs susceptibles d'avoir des teneurs en oxyde de chrome supérieures à 0,05 %.
Il s'agit d'une analyse du chrome total dans le cuir qui n'est spécifique ni d'un composant particulier ni de l'état d'oxydation.

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 5398-2 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 on IUC 8
originally published in J. Soc. Leather Tech. Chem., 49, p. 17, 1965, and declared an official method of the
IULTCS in 1965.
IULTCS, originally formed in 1897, is a world-wide organization of professional leather societies to further the
advancement of leather science and technology. IULTCS has three Commissions, which are responsible for
establishing international
