1 Scope This part of GB/T 223 specifies a gravimetric method for the determination of the sulfur content in steels and iron, excluding steels containing selenium. The method is particularly suitable as a reference method for the standardization of samples on which certified standard values are to be established. Method 1 is applicable to a sulfur content between 0.003 % (mass fraction) and 0.35 % (mass fraction). Method 2 is applicable to a sulfur content between 0.003 % (mass fraction) and 0.20 % (mass fraction).
