BS EN ISO 13365-1:2020

This standard BS EN ISO 13365-1:2020 Leather. Chemical determination of the preservative (TCMTB, PCMC, OPP, OIT) content in leather by liquid chromatography is classified in these ICS categories:

• 59.140.30 Leather and furs

This document specifies a test method by acetonitrile solvent extraction for the determination of the total content (solvent extractible) of the following preservative agents in leather by liquid chromatography:

1. 2-(thiocyanomethylthio)-benzothiazole (TCMTB);

2. 4-chloro-3-methylphenol (PCMC);

3. 2-phenylphenol (OPP);

4. 2-octylisothiazol-3(2H)-one (OIT);

This method can also be used to determine breakdown products of these preservative agents, which protect leather from microbiological attack.
