ISO 13365 1 is the first part of the multi series ISO 13365. ISO 13365 1 specifies a test method by acetonitrile solvent extraction for the determinate one of the total contents (solvent extractible) of the following preservative agents in leather by liquid chromatography: 2 (thiocyanomethylthio) benzothiazole (TCMTB) 4 chloro 3 methyl phenol (PCMC) 2 phenyl phenol (OPP) 2 octylisothiazol 3(2H) one (OIT) ISO 13365 1 can also
