DESCRIPTION
This standard BS EN ISO 11427:2016 Jewellery. Determination of silver in silver jewellery alloys. Volumetric (potentiometric) method using potassium bromide is classified in these ICS categories:
  • 39.060 Jewellery
The method of ISO 11427:2014 describes a volumetric method for the determination of silver in 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. This method is intended to be used as the referee method for the determination of fineness in alloys covered by ISO 9202.
