GB/T 8704.3-1997 Methods for chemical analysis of ferrovanadium. The infrared absorption method and the combustion neutralization titration method for the determination of sulfur content (English Version)
This standard applies to the determination of sulfur content in ferrovanadium. This standard specifies the following two methods for the determination of sulfur content in ferrovanadium. Method Ⅰ: infrared absorption method, measuring range: 0.005% to 0.120%. Method Ⅱ: Combustion neutralization titration method, measuring range: ≤0.120%.
