随着国际上铁矿石贸易量的增长,铁矿石标准的作用越来越显重要。我国作为铁矿石的进口大国,早在1986年就颁布实施了GB6730共51个化学分析方法标准。现将该系列标准与ISO对应标准作如下对比,供有关人员参考。1 在标准个数上的对比 (1)GB:51个,ISO:32个; (2)GB与ISO等同的标准个数:1个; (3)GB与ISO对应且方法原理类似的标准个数:15个; With the international trade of iron ore increasing, the role of iron ore standards is more and more important. As a big importer of iron ore in our country, as early as 1986, a total of 51 chemical analysis standards of GB6730 were promulgated and implemented. Now the series of standards and ISO corresponding standards for comparison as follows, for the reference of personnel. 1 Comparison of the standard number (1) GB: 51, ISO: 32; (2) GB and ISO equivalent number of standards: 1; (3) GB and ISO corresponding and the principle of a similar standard method Number: 15
