DIN EN ISO 13365

Testing acc. to ISO 13365: Leather - Chemical tests - Determination of the preservative (TCMTB, PCMC, OPP, OIT) content in leather by liquid chromatography

The former DIN EN ISO 13365 described the determination of the preservatives TCMTB, PCMC, OPP and OIT in leather by liquid chromatography. The standard has been withdrawn and replaced by two differentiated test methods, both of which are carried out in our laboratory as accredited procedures.

DIN EN ISO 13365-1 is used to determine the solvent-extractable total content of the preservatives. DIN EN ISO 13365-2, in contrast, determines the fraction extractable with artificial perspiration and thus enables an assessment of potential exposure to preservatives during the use of leather.
