適用范圍：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 atomic absorption spectromerty and is applicable to teathers which are expected to hace chromic oxide contents in excess of 5 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.
