本文件规定了感应炉内燃烧后的红外吸收法，用于测定0002%至0.12%范围内镍铁中的硫含量。 该方法适用于正常生产操作。它使用商用设备，使用钢和/或镍铁认证标准物质（CRM）进行校准。交叉引用:ISO 4934ISO 5725-2ISO 13902ISO 4935ISO 5725-3ISO 10701ISO 5725-1购买本文件时可获得的所有现行修订版均包含在购买本文件中。

This document specifies an infrared absorption method after combustion in an induction furnace for the determination of the sulfur content in ferronickels in the range of 0,002 % to 0,12 %. The method is applicable to normal production operations. It uses commercially available equipment, which is calibrated using steel and/or ferronickel certified reference materials (CRMs).Cross References:ISO 4934ISO 5725-2ISO 13902ISO 4935ISO 5725-3ISO 10701ISO 5725-1All current amendments available at time of purchase are included with the purchase of this document.
