Jewellery and precious metals — Determination of silver — Potentiometry using potassium bromide 珠宝和贵金属 银的测定 溴化钾电位法
发布日期: 2024-04-05
本文件规定了测定均匀材料中银的容量法。样品的银含量优选为(100~999,0)?质量千分之一(‰)。纯度999以上,0?‰可使用光谱法通过差异测定(例如ISO 15096)。 该方法旨在用作ISO?所涵盖的合金中细度测定的参考方法。9202.

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.
