scope:

This Standard specifies the method for determining carbon content in iron and steel by the infrared absorption method after combustion. This method is applicable to the carbon contents between 0.001 % to 5.0 % (mass fraction) inclusive, or when using reagents or carbon standard solutions for construction of calibration curve, between 0.003 % to 4.5 % (mass fraction) inclusive.

NOTE 2 The analysis method specified in this Standard may detect a higher carbon content than the actual carbon content of the test portion due to inclusion of the carbon adhered or adsorbed to the test portion in the analysis result. The error, however, is usually only about 0.000 2 % and never more than 0.000 5 % in mass fraction. For determination of trace amount carbon by excluding the influence of carbon adhered or adsorbed to the surface of the test portion, the method specified in JIS G 1211-4 can be used.  In the event of any doubt arising as to analytical value of carbon content of 0.001 % to 0.010 % to (mass fraction), the analytical value obtained according to JIS G 1211-4 should be adopted.

NOTE 3 The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 9556: 1989 Steel and iron-Determination of total carbon 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/IEC Guide 21-1.
