ISO 11495:2014描述了通过电感耦合等离子体发射光谱法(ICP-OES)测定钯首饰合金中的钯,优选在ISO 9202规定的细度范围内的方法。
合金的优选钯含量在500〜 (千分之一)和950?钯。
注意该方法可用于分析其他钯的含量。
该方法旨在用作ISO 9202涵盖的合金中确定细度的推荐方法
ISO 11495:2014 describes a method for the determination of palladium in palladium jewellery alloys, preferably within the range of fineness specified in ISO 9202, by means of inductively coupled plasma optical emission spectrometry (ICP-OES).
The preferred palladium content of the alloys lies between 500?(parts per thousand) and 950?palladium.
NOTE This method can be used to analyse other contents of palladium.
This method is intended to be used as the recommended method for the determination of fineness in alloys covered by ISO 9202.
