Leather - Chemical determination of chromic oxide content - Part 4: Quantification by inductively coupled plasma - optical emission spectrometer (ICP-OES) (ISO 5398-4:2007)
This part of ISO 5398 describes a method for the determination of chromium in aqueous solution obtained from leather. This is an analysis for total chromium in leather; it is not compound specific or specific to its oxidation state. This method describes the determination of chromium by inductively coupled plasma - optical emission spectrometry and is applicable to leathers which are expected to have chromic oxide contents in excess of 1 mg/kg. Two techniques for the preparation of the solution to be analysed are included. In the case of dispute, the wet oxidation technique is to be used.
Leder - Chemische Bestimmung des Chromoxidgehaltes - Teil 4: Bestimmung durch induktiv gekoppeltes Plasma/optisches Spektrometer (ICP-OES) (ISO 5398-4:2007)
Dieser Teil der ISO 5398 beschreibt ein Verfahren zur Bestimmung von Chrom in einer aus Leder erhaltenen wässrigen Lösung. Im vorliegenden Fall handelt es sich um eine Analyse des Gesamtchromgehaltes in Leder, die nicht verbindungsspezifisch oder spezifisch für die Oxidationsstufe ist.
Das vorliegende Verfahren beschreibt die Bestimmung von Chrom durch induktiv gekoppeltes Plasma – Optische Emissionsspektrometrie und ist vorgesehen für die Anwendung bei Ledern, bei denen Chromoxidgehalte im Bereich von mehr als 1 mg/kg vermutet werden.
Enthalten sind zwei Verfahren zur Herstellung der zu analysierenden Lösung. Im Streitfall ist das Nassoxidationsverfahren anzuwenden.
Cuir - Dosage de l'oxyde de chrome - Partie 4: Quantification par plasma a couplage inductif/spectrométrie d'émission optique (ICP-OES) (ISO 5398-4:2007)
L'ISO 5398-4:2007 spécifie une méthode permettant de doser le chrome dans une solution aqueuse obtenue à partir de cuir. C'est une analyse du chrome total dans le cuir; elle est non spécifique du composé chromé ou de l'état d'oxydation du chrome.
La présente méthode indique comment doser le chrome par plasma à couplage inductif – spectrométrie d'émission optique et elle s'applique aux cuirs susceptibles de contenir de l'oxyde de chrome dans des proportions supérieures à 1 mg/kg. Deux techniques de préparation de la solution à analyser sont décrites. En cas de désaccord, c'est la méthode d'oxydation en milieu humide qui doit être utilisée.

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.
This part of ISO 5398 was prepared by the Chemical Tests Commission of the International Union of Leather
Technologists and Chemists Societies (IUC Commission, IULTCS) in collaboration with the European
Committee for Standardization (CEN) Technical Committee CEN/TC 289, Leather, the secretariat of which is
held by UNI, in accordance with the agreement on technical co-operation between ISO and CEN (Vienna
Agreement). It is based on IUC 8 originally published in J. Soc. Leather Trades Chemists 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 methods for the sampling and testing of leather. ISO recognizes IULTCS as an
