DIN EN ISO 5398-1:2007 PDF

Scope: 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 detemination of chrome by iodometric tiration and is to be applicable to chromium-tanned leathers which are expected to have chromic oxide contents in excess of 0,3%.Two different methods are described as alternatives for obtaining chromiun in a suitable solution.It is appropriate to use either method.
