Leather - Chemical determination of chromic oxide content - Part 1: Quantification by titration (ISO 5398-1:2007)

ISO 5398-1:2007 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 chrome by iodometric titration and is to be applicable to chromium-tanned leathers which are expected to have chromic oxide contents in excess of 0,3 %. Two different methods are described as alternatives for obtaining chromium in a suitable solution. It is appropriate to use either method.

Leder - Chemische Bestimmung des Chromoxidgehalts - Teil 1: Bestimmung durch Titration (ISO 5398-1:2007)

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.
Dieses Verfahren beschreibt die Bestimmung von Chrom durch jodometrische Titration und ist vorgesehen für mit Chrom gegerbte Leder, bei denen Chromoxidgehalte von mehr als 0,3 % vermutet werden. Es werden zwei unterschiedliche Verfahren als Alternative zum Erhalt von Chrom in einer geeigneten Lösung beschrieben. Es ist angebracht, beide Verfahren anzuwenden.

Cuir - Dosage chimique de l'oxyde de chrome - Partie 1: Quantification par titrage (ISO 5398-1:2007)

L'ISO 5398-1:2007 spécifie une méthode permettant de doser le chrome dans une solution aqueuse obtenue à partir de cuir. C'est une analyse du chrome total contenu dans le cuir; elle est non spécifique du composé de chrome ou de son état d'oxydation.
La présente méthode indique comment doser le chrome par titrage iodométrique; elle doit être applicable aux cuirs tannés au chrome, susceptibles de contenir de l'oxyde de chrome dans des proportions supérieures à 0,3 %. Deux méthodes différentes sont décrites pour obtenir du chrome dans une solution appropriée. Ces deux méthodes peuvent être appliquées.
