标准摘要
[中文适用范围]： 规定了评估锰矿石和铬矿石质量变化的实验方法，无论是天然矿石还是加工矿石，目的是通过相关国际标准中规定的基于质量的系统方法和两阶段方法来定义采样程序。 还规定了质量基系统法和两阶段法检验采样精度的方法。 [外文原描述]： 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.
英文名称Manganese and chromium ores — Experimental methods for evaluation of quality variation and methods for checking the precision of sampling
