标准摘要
[中文适用范围]： 本文件规定了贵金属和贵金属合金的取样方法，以确定其贵金属含量并评估其均匀性。 本文件适用于原材料、半成品和成品，仅用于全金属材料的取样。 注 1：不同金属的贵金属含量测定标准列于参考文献中。 注 2：对于与所列技术不同的测定技术，可能需要其他采样程序。 注 3：出于生产控制或批量检验的目的，可以另外应用参考书目或相应指南中所示的国际抽样标准。 [外文原描述]： This document specifies a method of sampling precious metals and precious metal alloys for the determination of their precious metal content and for the assessment of their homogeneity. The document is applicable to raw materials, semi-finished products and finished products and is intended to be used only for the sampling of entirely metallic materials. NOTE 1 Standards for determination of precious metals contents for different metals are listed in the Bibliography. NOTE 2 For assaying techniques different from the listed ones other sampling procedures can be required. NOTE 3 For the purpose of production control or lot inspections the International Standards for the sampling indicated in the Bibliography or corresponding guidelines can be applied in addition.
