Foreword

This Standard equivalently adopts ISO 15349-2:1999 Unalloyed Steel – Determination of Low

Carbon Content – Part 2: Infrared Absorption Method after Combustion in an Induction

Furnace (with Preheating).

This Standard equivalently translates ISO 15349-2:1999.

For the ease of use, this Standard made the following editorial modifications:

a) Change "this International Standard" into "this Standard";

b) Use the "decimal point' to replace the "comma", which is used as the decimal point;

c) Delete the foreword of the international standard.

The Annexes A, B, C of this Standard are informative.

Unalloyed Steel – Determination of

Low Carbon Content – Part 2: Infrared Absorption Method

after Combustion in an Induction Furnace (with Preheating)

1 Scope

This Standard specifies an infrared absorption method after combustion in an induction furnace

for the determination of the low carbon content in unalloyed steel.

The method is applicable to carbon contents between 0.000 3 % (m/m) and 0.010 % (m/m).
