Abstract

Specifies experimental methods for the evaluation of quality variation of manganese and chromium ores, whether natural or processed, for the purpose of defining sampling procedure by the mass-basis systematic method and the two-stage method as specified in the relevant International Standards. It also specifies methods for checking the precision of sampling by the mass-basis systematic method and the two-stage method.
