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).

This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes],
Subcommittee SC 3, Welding consumables, in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 121, Welding, in accordance with the Agreement
on technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 14341:2010), which has been technically
revised. The main changes compared to the previous edition are as follows:
— all references have been updated;
— in Table 3A, the footnote for Cu that appeared in the 2008 edition has been reintroduced;
— in Table 3B and Table 4B, a new symbol S8 has been added;
— in Table 3B, Ni, Cr, Mo and V values have been added for symbols S2, S3, S4, S5, S6, and S7;
— Clause 8 has been updated to the latest agreed text;
— in Clause 11, an example for a Z classification has been added as Example 2A.

Introduction
This document recognizes that there are two somewhat different approaches in the global market to
classifying a given wire electrode, and allows for either or both to be used, to suit a particular market
need. Application of either type of classification designation (or both where suitable) identifies a
product as classified in accordance with this document.
This document provides a classification in order to designate wire electrodes in terms of their chemical
