标准编号：ISO 15350:2000

中文名称：钢和铸铁-碳和硫磺含量的测定-感应炉中燃烧后红外线吸收法（常规方法）

英文名称：Steel and iron — Determination of total carbon and sulfur content — Infrared absorption method after combustion in an induction furnace (routine method)

发布日期：2000-12

标准范围

本国际标准规定了在感应炉中燃烧后的红外吸收方法，用于钢铁中总碳和硫含量的测定。该方法适用于质量分数在0005%至4.3%之间的碳含量和硫含量质量分数在0.5%和0.33%之间。该方法旨在用于正常生产操作，并旨在满足所有普遍接受的要求，认可实验室认证机构期望的良好实验室实践。它使用商用设备，使用钢铁认证参考进行校准和校准验证使用常规统计过程控制（SPC）实践对其性能进行控制。该方法可用于单元素模式，即单独或单独测定碳和硫同时模式，即同时测定碳和硫。

This International Standard specifies an infrared absorption method, after combustion in an induction furnace, forthe 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 ofmass 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 usescommercially available equipment, is calibrated and calibration verified using steel and iron certified referencematerials, 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 inthe simultaneous mode, i.e., determination of carbon and sulfur concurrently.
