Scope
WARNING: Personnel using this section should have practical experience in formal laboratory work. This section does not address all possible security issues. It is the user's responsibility to take appropriate safety and health measures and ensure compliance with the conditions stipulated in the relevant national laws and regulations. 1 Scope This part of GB/T 21931 specifies the determination of carbon content in nickel, nickel-iron and nickel alloys by high-frequency induction combustion infrared absorption method. This section applies to the determination of carbon content (mass fraction) in nickel and ferronickel of 0.001% to 2.0%, and carbon content (mass fraction) in nickel alloy of 0.001% to 0.5%. See Appendix A for examples of nickel, nickel-iron and nickel alloy compositions.
