Jewellery and precious metals — Determination of palladium — Gravimetry using dimethylglyoxime 珠宝和贵金属.钯的测定.丁二酮肟重量法
发布日期: 2023-02-17
本文件规定了测定均匀材料上钯的重量法。样品的钯含量优选为50~999质量份/千(‰)。纯度999以上?‰可使用光谱法通过差异测定(例如ISO 15093)。 该方法也旨在用作测定ISO 9202涵盖的珠宝合金细度的推荐方法之一。

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.
