GB/T 5687.4-2016 Nitrogen-bearing ferrochromium and nitride ferrochrome with high nitrogen content—Determination of nitrogen content—The distillation-neutralization titration method
Abstract
This part of GB/T 5687 specifies the determination of nitrogen content in chromium nitride and high-nitrogen chromium iron by distillation and titration. This part is applicable to the determination of nitrogen content in chromium nitride and high-nitrogen chromium iron. The determination range of nitrogen in chromium nitride (mass fraction): 2.00%~7.00%; the determination range of nitrogen in high-nitrogen chromium iron (mass fraction): >7.00%~12.00%.
