具有一种或多种良好特性,这种特性可用来校准测量仪器,评价测量方法或确定其它材料的特性的物质被称为标准物质.对那些用技术上正确的方法已确定了其一种或几种特性值的标准物质,且这些特性值可追溯到由定值部门所发布的证书或其它文件,则称这些标准物质为认证标准物质或保证标准物质(以下简称标准物质或CRM).钢铁化学标准物质在验证分析方法、校正仪器、检查操作技术、标定溶液浓度和绘制工作曲线等方面有着广泛的用途,尤其是在仲裁分析时,它作为定值的依据,对于提高分析水平,保证产品质量起着极大的作用.
A substance that has one or more good characteristics that can be used to calibrate a measuring instrument, evaluate a measurement method, or determine the identity of other materials is referred to as a reference substance For those who have technically correct methods that have identified one or Several characteristic values of the standard material, and these characteristics can be traced back to the certificate issued by the value department or other documents, these standards are called certified reference material or guaranteed reference material (hereinafter referred to as the standard material or CRM). It has a wide range of uses in validation and analysis methods, calibration instruments, inspection and operation techniques, calibration solution concentration, and drawing working curves. Especially in the arbitration analysis, it is used as a basis for setting value and for improving the level of analysis and guaranteeing products Quality plays a big role.
