New BiH standard in the field of precious metals adopted by translation method

BiH standard BAS ISO 13756: 2015, Jewellery - Determination of silver in silver jewellery alloys - Volumetric (potentiometric) method using sodium chloride or potassium chloride, the second edition, is the translation of the English version of international standard ISO 13756: 2015 Jewellery - Determination of silver and silver jewellery alloys - Volumetric (potentiometric) method using sodium chloride or potassium chloride.

 

The original text of the international standard has been prepared by the Technical Committee ISO/TC 174, Jewellery.

 

This International Standard specifies the volumetric method for the determination of silver in silver jewelry 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 the titration, these elements do not interfere with this method of determination.

This standard replaces BiH standard ISO 13756: 2010.

 

Translation of BAS ISO 13756: 2015 was prepared by the Technical Committee BAS/TC 38 Metrology and measurements, of the Institute for Standardization of Bosnia and Herzegovina.
