Leather. Chemical tests. Determination of matter soluble in dichloromethane and free fatty acid content Ingestion-build-177197 BS EN 60371-3-1 is a1 Scope This document specifies a method for the determination of the substances in leather which are soluble in dichloromethane. This method is applicable to all types of leather. Not all fatty and similar substances can be extracted from leather with organic solvents; they may be in part soluble and partly bound to the leather. On the other hand, the solvent can dissolve non fatty substances, for example sulfur and impregnants, both of which cause
