GSO ISO 13756:2021 Scope
ISO 13756:2015 specifies a volumetric method for the determination of silver in silver jewellery alloys, preferably within the range of fineness stated in ISO 9202. These alloys may contain copper, zinc, cadmium, and palladium. Apart from palladium, which must be precipitated before commencing titration, these elements do not interfere with this method of determination.
NOTE This method is an alternative recommended method to ISO 11427.
