Leather. Chemical tests. Determination of volatile matter subscription-only Note 1: External quality assessment1 Scope This International Standard specifies a method of determination of volatile matter which is applicable to all leather types. It is not possible to determine the exact moisture content of leather by this method. This is because at elevated temperatures other volatile substances escape and tannins and fats can be oxidized. Some absorbed water may be left in the leather after drying.
