This International Standard specifies a method for the
determination of the sulphated total ash and the sulphated
watet--insoluble ash of leather.
The method is applicable to all types of leather.
The determination may be inaccurate by the extent to
which the leather contains organo-metallic compounds,
for example Silicone (see note 1 in 8.1).
