- Scope
- This standard specifies the distillation separation-neutralization titration method for the determination of nitrogen content. This standard is applicable to the determination of nitrogen content in alloy steel and high-temperature alloys, but not applicable to the determination of nitrogen content in silicon steel and its profiles without aluminum smelting. Measuring range: 0.010% to 0.50%.
