<p>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.</p>
<p>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.</p>
<p>This method is intended to be used as the referee method for the determination of fineness in alloys covered by ISO 9202.</p>
