《GB/T 27680-2011铜、铅、锌和镍精矿检查取样误差的实验方法》由TC243（全国有色金属标准化技术委员会）归口，TC243SC2（全国有色金属标准化技术委员会重金属分会）执行，主管部门为中国有色金属工业协会。

Scope

This standard specifies the experimental method for checking the sampling errors of copper, lead, zinc and nickel concentrates, and the sampling method is in accordance with ISO 12743. The methods specified in this standard can also be used to check for errors in sample handling and to check for significant differences that may exist in the analysis of exchanged samples and batches at different locations (such as loading and unloading points).
