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

Introduction
This International Standard classifies welding consumables for fusion welding of various types of
unalloyed cast irons.
Applications for welding consumables classified to this International Standard:
— production welding, that means welding of cast materials during the process of production. In that
way, the quality of the casting shall be ensured in accordance with the guaranteed properties and
to the requirements of the application;
— repair welding of castings which are damaged during service;
— welding for construction purposes where cast irons are joined to themselves or to other ferrous or
non-ferrous metals.
The following methods are used for the welding of cast irons:
— using a welding consumable which
