标准摘要
[中文适用范围]： 本标准规定了在感应炉中燃烧后测定钢和铁中总碳和硫含量的红外吸收法。 该方法适用于质量分数在0.005%至4.3%之间的碳含量和质量分数在0.000 5%至0.33%之间的硫含量。 该方法旨在用于正常生产操作，并旨在满足公认的实验室认证机构所期望的所有普遍接受的良好实验室实践。 它使用市售设备，使用钢铁认证参考材料进行校准和校准验证，并使用正常的统计过程控制 (SPC) 实践来控制其性能。 该方法可用于单元素模式，即独立测定碳和硫，也可用于同时模式，即同时测定碳和硫。 [外文原描述]： This International Standard specifies an infrared absorption method, after combustion in an induction furnace, for the determination of the total carbon and sulfur content in steel and iron. The method is applicable to carbon contents of mass fraction between 0,005 % and 4,3 % and to sulfur contents of mass fraction between 0,000 5 % and 0,33 %. This method is intended to be used in normal production operations and is intended to meet all generally accepted, good laboratory practices of the type expected by recognized laboratory accreditation agencies. It uses commercially available equipment, is calibrated and calibration verified using steel and iron certified reference materials, and its performance is controlled using normal statistical process control (SPC) practices. This method can be used in the single element mode, i.e., determination of carbon and sulfur independently or in the simultaneous mode, i.e., determination of carbon and sulfur concurrently.
