This Standard specifies the infrared absorption method after combustion in a high frequency induction furnace for the determination of sulfur content in iron and steel.

This method is applicable to the determination of sulfur content rate (mass fraction) of 0.002 % or over to and including 0.35 % in pig iron and cast iron, and the determination of sulfur content rate (mass fraction) of 0.000 5 % or over up to and including 0.50% in steel.

However, it is applicable to the determination of sulfur content rate (mass fraction) of 0.002 % or over up to and including 0.10 % in iron and steel in the case of preparing the calibration curve using the sulfur reference solution, to the determination of sulfur content rate (mass fraction) of 0.10 % or over up to and including 0.35 % in iron and steel in the case of preparing the calibration curve using barium sulfate, or the determination of sulfur content rate (mass fraction) of 0.003 0 % or over up to and including 0.20 % in pig iron and cast iron and the determination of sulfur content rate (mass fraction) of 0.000 5 % or over up to and including 0.50 % in steel in the case of preparing the calibration curve using steel and iron certified reference material.

NOTE 2 The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 4935 : 1989 Steel and iron – Determination of sulfur content – Infrared absorption method after combustion in an induction furnace

ISO 13902 : 1997 Steel and iron – Determination of high sulfur content – Infrared absorption method after combustion in an induction furnace

ISO 15350 : 2000 Steel and iron – Determination of total carbon and sulfur content – Infrared absorption method after combustion in an induction furnace (routine method) (Overall evaluation: MOD)

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.
