Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

The committee responsible for this document is ISO/TC 17, Steel, Subcommittee SC 1, Methods of determination of chemical composition.

This first edition Technical Specification replaces the first edition Technical Report (ISO/TR 10719:1994), which has been technically revised. The following changes have been made:

• steels have been deleted from the scope;
• the possibility to establish the calibration curve by means of certified reference materials has been added;
• assessment of the precision data has been revised.

1 Scope

This document specifies an infrared absorption method after combustion in an induction furnace for the determination of non-combined carbon content in cast irons.

The method is applicable to non-combined carbon contents between 1,0 % (mass fraction) and 3,0 % (mass fraction).

Elements ordinarily present do not interfere. However, some alloyed cast irons, when extensively heat treated, contain carbides that are not soluble when using this method and may give high values for non-combined carbon.
