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:
-
2-(thiocyanomethylthio)-benzothiazole (TCMTB);
-
4-chloro-3-methylphenol (PCMC);
-
2-phenylphenol (OPP);
-
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.
