scope:

This Standard 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.

The method is applicable to a sulfur content between 0.003 % (mass fraction) and 0.35 % (mass fraction).

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 4934 : 2003 Steel and iron-Determination of sulfur content-Gravimetric method (IDT)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ lEC Guide 21-1.
