适用范围：This part of ISO 5398 describes a method for the determination of chromium in aqueous solution obtainedfrom leather. This is an analysis for total chromium in leather; it is not compound specific or specific to itsoxidation state.This method describes the determination of chrome by iodometric titration and is to be applicable tochromium-tanned leathers which are expected to have chromic oxide contents in excess of 0,3 %. Twodifferent methods are described as alternatives for obtaining chromium in a suitable solution. It is appropriateto use either method.
