Leather — Chemical determination of the preservative (TCMTB, PCMC, OPP, OIT) content in leather by liquid chromatography — Part 2: Artificial perspiration extraction method

Scope

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.
