DESCRIPTION
BS EN ISO 5398-1:2018
This standard BS EN ISO 5398-1:2018 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 chrome by iodometric titration 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 chromium in a suitable solution. It is appropriate to use either method.
