英文名称：Copper, lead, zinc and nickel concentrates — Experimental methods for checking the bias of sampling
发布日期：2006-03
标准范围
This International Standard specifies methods for checking whether there is any bias in the sampling of copper, lead, zinc and nickel concentrates, where the sampling is carried out in accordance with the methods specified in ISO 12743. These methods can also be used for comparing alternative sampling regimes, checking whether there is any bias in sample processing and for checking possible significant differences in sampling at different places, e.g. at loading and discharge points, or the analysis of exchange samples. Numerical examples are given in Annex A.
