ISO 11427:2024 Scope
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.
