标准摘要
[中文适用范围]： 本文件规定了一种容量法，用于测定被视为均质的材料中的银含量。样品的银含量最好在（100 至 999,0）‰ 之间（按质量计算）。999,0 ‰ 以上的纯度可以通过差分光谱法确定（例如，本方法旨在用作 ISO 9202 所涵盖的合金纯度测定的参考方法。 [外文原描述]： 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.
