DESCRIPTION
EN ISO 5398-1
EN ISO 5398-1 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.
The price of the Standard included all amendments and correcturs.
