Leather. Chemical tests. Determination of water-soluble matter, water-soluble inorganic matter and water-soluble organic matter algolia-ignore they form the racemic mixture1 Scope This document specifies a method of determination of water soluble matter, water soluble inorganic matter and water soluble organic matter. It is applicable to all leather types. The result obtained by this analysis depends on factors such as: the degree to which the leather is ground; the extraction temperature; the extraction period; the ratio of leather to water. To obtain comparable results, it is consequently imperative that test
