This document specifies a method for determining the use of certain azo colourants which can release
certain aromatic amines.

This document specifies a test method by acetonitrile solvent extraction for the determination
of the total content (solvent extractible) 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

This document specifies a test method to determine the degree and rate of aerobic biodegradation
of hides and skins of different animal origin, whether they are tanned or not, through the indirect
determination of CO2 produced by the degradation of collagen.
The test material is exposed to an inoculum (activated sludge from tannery wastewater) in an aqueous
medium. If there is not a tannery nearby then urban wastewater can be used as the inoculum.
The conditions established in this document...view more

This document specifies a method for determining the tensile strength, elongation at a specified load
and elongation at maximum force of leather. It is applicable to all types of leather.

This document defines various preservation methods for raw hides. These preservation methods are intended to suppress microbiological activity and to maintain the quality and commercial value of the hides during storage. This document applies to all raw hides of cattle and horses.

This document provides guidelines for various preservation methods for raw goat and sheep skins. The preservation methods are needed to suppress microbiological activity and to maintain the quality of the skins during storage.

This document specifies a method for determining the tensile strength, elongation at a specified load and elongation at maximum force of leather. It is applicable to all types of leather.
