The standard sample Research Institute of Shandong Academy of metallurgical SciencesCo., Ltd. is an important base for the development and sales of metallurgical, non-ferrousmetals, coal, building materials, chemical industry, environmental protection and otherstandard samples(substances)in China. It is also one of the important units to carry out theanalysis and testing of metal and non-metallic materials, research and promote newtechnology of metal and non-metallic material analysis, and cultivate metallurgical analysistalents. The Institute has obtained the qualification of national accreditation testinglaboratory( NO.CNAS L1461), certified reference material/reference sample manufacturerqualification( NO.CNAS RM0012).the national metallurgical standard sample, the nationalnon-ferrous metal standard sample fixed-point development and sales unit. The Institutehas developed standard samples (substances) for more than 50 years, involving metallurgy,non-ferrous metals, coal, chemical industry, environment and other industries, includingmetallurgical raw materials, ferrous metals, non-ferrous metals, coal and coke, includingchemical analysis, spectral analysis, standard solution, physical metallographic samples andother professional standard samples (substances). Among more than 1000 kinds of standardsamples developed, there are more than 100 national first-class standard samples(substances) and more than 1000 industrial standard samples (substances)
