Scope

This part of GB/T 21931 specifies the determination of the carbon content in nickel, nickel-iron and nickel alloys by the infrared absorption method after high-frequency induction combustion.
This section applies to the carbon content (mass fraction) in nickel and ferronickel for 0.001% to 2.0%, and the carbon content (mass fraction) in nickel alloys is
0.001% to 0.5% determination. Examples of the composition of nickel, nickel-iron and nickel alloys are shown in Appendix A.

Summary	This standard specifies the high frequency induction combustion infrared absorption method for the determination of nickel, nickel-iron and nickel alloy carbon content. This section applies to nickel and nickel-iron-carbon content (mass fraction) of 0. 001% to 2. 0%, nickel alloy carbon content (mass fraction)] from 0. 001% to 0. 5% of the measurement. Nickel, ferronickel and nickel alloy chemical composition examples see Appendix A.
