DETERMINATION OF SILVER IN SILVER JEWELLERY ALLOYS - VOLUMETRIC (POTENTIOMETRIC) METHOD USING POTASSIUM BROMIDE (ISO 11427:1993, COR. 1:1994, IDT)
This Malaysian 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 topper, 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 1 This method is intended to be used as the referee method for the determination of fineness in the alloys covered by ISO 5202.
