Sets out methods for checking whether there is bias in the sampling of sulfide concentrates. Numerical examples are provided. This Standard is identical with and has been reproduced from ISO 13292:1997.

This International Standard specifies methods for checking whether there is any bias in the sampling of copper, lead and zinc sulfide concentrates, where the sampling is carried out in accordance with the methods specified in ISO 12743. These methods can also be used for checking whether there is any bias in sample processing and for checking possible significant differences in the analyses of exchange samples and lot samples taken at different places, e.g. at loading and discharge points. Numerical examples are given in annex A.
