标准摘要
[中文适用范围]： 本文件规定了一种用于测定被认为均匀材料中银含量的分析方法。样品中的银含量优选在50 ‰（千分之一）至990 ‰（千分之一）之间。银含量高于990,0 ‰时，可采用差值光谱法进行测定（参见ISO 15096）。注：本方法也可用于测定较低含量的银。 [外文原描述]： This document specifies an analytical method for the determination of silver on a material considered homogeneous. The silver content of the samples lies preferably between 50 ‰ (parts per thousand) and 990 ‰ (parts per thousand). Fineness above 990,0 ‰ can be determined using a spectroscopy method by difference (see ISO 15096). NOTE Lower contents of silver can be analysed according to this method.
