GB/T 7731.12-2008 Ferrotungsten—Determination of sulfur content—Infrared absorption method and combustion titration method
Abstract
This section specifies the determination of sulfur content by infrared absorption method and combustion neutralization titration method. This section is applicable to the determination of sulfur content in tungsten iron. The determination range (mass fraction) of the infrared absorption method is 0.005% to 0.25%; the determination range (mass fraction) of the combustion neutralization titration method is 0.005% to 0.25%.
