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 Atomic Absorption Spectrometry and is intended to be applicable to leathers which are expected to have chromic oxide contents in the range 5;5000ppm. This is an analysis for total chromium in leather, not compound specific or specific to its oxidation state. The standard includes two techniques for preparation of the solution to be analysed. In case of dispute the wet oxidation technique shall be used.
