Content DescriptionThis 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. NOTEÂ 1Â Â Standards for determination of precious metals contents for different metals are listed in the Bibliography. NOTEÂ 2Â Â For assaying techniques different from the listed ones other sampling procedures can be required. NOTEÂ 3Â Â 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. About ISOISO, the International Organization for Standardization, brings global experts together to agree on the best way of doing things – for anything from making a product to managing a process. As one of the oldest non-governmental international organizations, ISO has enabled trade and cooperation between people and companies all over the world since 1946. The International Standards published by ISO serve to make lives easier, safer and better. |
