Scope

This standard specifies the method of determining the content of lanthanum, cerium, and magnesium by inductively coupled plasma atomic emission spectrometry.
This method is suitable for determining the content of lanthanum, cerium, and magnesium in cast iron and low-alloy steel. The measurement range (mass fraction): lanthanum, 0.002% to 0.10%; cerium, 0.005% to 0.15%; magnesium, 0.003% to 0.15%.
