Summary
This document specifies a volumetric method for dosing silver on a material considered homogeneous. The silver content of the samples is preferably between 100 and 999.0 thousandths (‰) by mass. Titers above 999.0‰ can be determined using a difference spectroscopy method (e.g. ISO 15096). This method is intended to be used as a reference method for the determination of fineness in alloys covered by ISO 9202.
