Scope

This part of GB/T 21931 specifies the high-frequency induction furnace combustion infrared absorption method for the determination of sulfur content in nickel, nickel-iron and nickel alloys.
This part is applicable to the sulfur content of nickel and ferronickel from 0.001% to 0.3% (mass fraction) and the sulfur content of nickel alloy from 0.001% to 0.1%
(Mass score) determination. See Appendix A for examples of ingredient composition.
