Annotation of standard text ČSN EN ISO 13365-2 (793874):

This document specifies a test method by artificial perspiration solution aqueous extraction for the determination of the aqueous extractable content 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
