《GB/T 3286.7-2014石灰石及白云石化学分析方法　第7部分：硫含量的测定 管式炉燃烧-碘酸钾滴定法、高频燃烧红外吸收法和硫酸钡重量法》由TC183（全国钢标准化技术委员会）归口，TC183SC17（全国钢标准化技术委员会冶金非金属矿产品分会）执行，主管部门为中国钢铁工业协会。
GB/T3286的本部分规定了用管式炉燃烧-碘酸钾滴定法、高频燃烧红外吸收法和硫酸钡重量法测定硫含量。
本部分适用于石灰石、白云石中硫含量的测定,及冶金石灰中硫含量的测定。管式炉燃烧-碘酸钾滴定法和高频燃烧红外吸收法测定范围(质量分数)为0.01%~0.5%;硫酸钡重量法测定范围(质量分数)为硫含量大于或等于0.10%;附录 B 管式炉燃烧-碘滴定法测定范围(质量分数)为硫含量不小于0.01%。

Scope

This part of GB/T 3286 specifies the determination of sulfur content by tube furnace combustion-potassium iodate titration method, high-frequency combustion infrared absorption method and barium sulfate gravimetric method. This section applies to the determination of sulfur content in limestone and dolomite, and the determination of sulfur content in metallurgical lime. The measurement range (mass fraction) of tube furnace combustion-potassium iodate titration method and high-frequency combustion infrared absorption method is 0.01%~0.5%; the measurement range (mass fraction) of barium sulfate gravimetric method is that the sulfur content is greater than or equal to 0.10%; appendix B tube furnace combustion - iodine titration measurement range (mass fraction) sulfur content is not less than 0.01%.
