- 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 inductively coupled plasma-optical emission spectrometry and is applicable to leathers which are expected to have chromic exide contents in excess of 1mg/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.
