Jewellery and precious metals — Determination of silver — Potentiometry using sodium chloride or potassium chloride
This document specifies a volumetric method for the determination of silver on a material considered homogeneous. The silver content of the sample lies preferably between (100 and 999,0)?parts per thousand (‰) by mass. Fineness above 999,0?‰ can be determined using a spectroscopy method by difference (e.g. ISO 15096).
This method is intended to be used as the reference method for the determination of fineness in alloys covered by ISO?9202.
