BS EN ISO 13365:2011

Leather. Chemical tests. Determination of the preservative (TCMTB, PCMC, OPP, OIT) content in leather by liquid chromatography. | Status: Superseded, Withdrawn

1 Scope This International Standard specifies a test method for the determination of the content of the following preservative agents:

• — 2-(thiocyanomethylthio)-benzothiazole (TCMTB);
• — 4-chloro-3-methylphenol (PCMC);
• — 2-phenylphenol (OPP);
• — 2-octylisothiazol-3(2H)-one (OIT);

in leather by liquid chromatography. Preservative agents are necessary to protect leather from microbiological attack.

NOTE The preservative agents 4-chloro-3-methylphenol (PCMC) and 2-phenylphenol (OPP) can also be determined according to ISO 17070 and quantified by means of gas chromatography/mass spectroscopy (GC/MS).
