This Standard describes a method for the determination of chromium in aqueous solution obtained from leather and is an updated version of the existing IULTCS method IUC 8. This describes the determination of chrome by iodometric titration and is intended to be applicable to chromium tanned leathers which are expected to have chromic oxide contents in excess of 0,25%. Two different methods are described as alternatives for obtaining chromium in a suitable solution. It is appropriate to use either method. This is an analysis for total chromium in leather, not compound specific or specific to its oxidation state.
