| Resumen: | 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 (<0/00>) by weight. Fineness above 999,0 <0/00> 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. |
