1 Overview In 1952, the metallurgical industry developed and promulgated the first batch of standard samples for chemical analysis of steel, ferroalloy and iron ore in China in order to unify the analysis methods of steel and raw materials and establish standard samples under the auspices of the National Physical and Chemical Testing Commission. These standards The sample plays an important role in the uniform analysis of methods, training of chemical analysis personnel and improving the quality of analysis. With the development of metallurgical industry and standard chemical industry
