标准摘要
[中文适用范围]： 本文件规定了测定均质材料中钯含量的重量分析方法。 样品的钯含量优选为50至999质量份(‰)。 超过999‰的细度可以使用差值光谱法（例如ISO 15093）来确定。 该方法也旨在用作 ISO 9202 涵盖的珠宝合金纯度测定的推荐方法之一。 [外文原描述]： This document specifies a gravimetric method for the determination of palladium on a material considered homogeneous. The palladium content of the sample lies preferably between 50 and 999 parts per thousand (‰) by mass. Fineness above 999 ‰ can be determined using a spectroscopy method by difference (e.g. ISO 15093 ). This method is also intended to be used as one of the recommended methods for the determination of fineness in jewellery alloys covered by ISO 9202 .
