National standard samples for coke physical properties and chemical composition analysis of coal standard materials

Zhongbiao Quandong Metallurgical Coke Coal Standard Sample Physical Characteristics and Chemical Composition Analysis of Coke National Standard Sample

The coke standard samples developed by Jinan Zhongbiao Technology Jinan Quandong Standard Materials Research Institute and Jinan Metallurgical Science Research Institute not only cover the physical properties of coke, but also delve into the analysis of chemical composition. These standard samples provide important reference basis for China's coke industry, effectively promoting industry standardization and normalization. Among them, although the reference or information values of certified reference materials lack clear metrological traceability, their main purpose is still to help users understand the matrix composition of reference materials, judge the applicability of reference materials, or use them for measurement quality control depending on their reliability. The standard materials and samples developed by these institutions are approved by the Standards Department of the International Bureau of Technical Supervision and released by the National Bureau of Technical Supervision, ensuring their authority and accuracy.
