DESCRIPTION

BS EN ISO 5398-3:2018


This standard BS EN ISO 5398-3:2018 Leather. Chemical determination of chromic oxide content is classified in these ICS categories:
  • 59.140.30 Leather and furs

This document 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 spectrometry and is applicable to leathers which are expected to have 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 disputes, the wet oxidation technique is to be used.
