在金属材料的研究和生产过程中,为了对材料质量的控制要进行大量的分析测试工作。标准物质(又称标准样品)的应用在保证分析质量,验证分析方法,校验仪器等方面是必不可少的。各工业发达国家都有较长的研制和应用标准物质的历史。我国在解放后的1951年为适应冶金工业的发展需要,受当时重工业部的委托由重工 In the research and production of metal materials, a large amount of analytical and testing work is required in order to control the material quality. The use of standard materials (also known as standard samples) is essential to ensure the quality of analysis, verification analysis methods, calibration instruments and so on. All industrialized countries have a long history of developing and applying standard substances. In 1951, China’s liberation to meet the needs of the development of metallurgical industry, commissioned by the then Ministry of Heavy Industry by the Heavy Industries
