Jewellery and precious metals - Determination of silver - Potentiometry using potassium bromide (ISO 11427:2024)
17-04-2024
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 ISO9202.
