Copper, lead, zinc and nickel concentrates. Experimental methods for checking the bias of sampling Ingestion-build-79769 This European Standard applies to1 Scope 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
