Scope

This document specifies a spectrophotometric method for the determination of nitrogen in steel. The method is applicable to the determination of nitrogen mass fraction between 0@000 6 % and 0@050 % in low alloy steels and between 0@010 % and 0@050 % in high alloy steels. The method does not apply to samples containing silicon nitrides or having silicon contents higher than 0@6 %.
