BS EN ISO 13365:2011 PDF

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).
