Scope

This International Standard 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 method to ISO 11427 which has been identified as the reference method. note: 1) ISO 11427:1993, Determination of silver in silver jewellery alloys — Volumetric (potentiometric) method using potassium bromide.
