ISO 13292:2006规定了检查铜、铅、锌和镍精矿取样中是否存在偏差的方法，其中按照ISO 12743规定的方法进行取样。这些方法还可用于比较替代取样制度，检查样品处理中是否存在任何偏差，以及检查不同地点（如装货点和卸货点）取样中可能存在的显著差异，或交换样品的分析。

ISO 13292:2006 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.
