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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 14172 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 3, Welding consumables.
This second edition cancels and replaces the first edition (ISO 14172:2003), which has been technically
revised. It also incorporates the Technical Corrigenda ISO 14172:2003/Cor.1:2004 and
ISO 14172:2003/Cor.2:2005.
Requests for official interpretations of any aspect of this International Standard should be directed to the
Secretariat of ISO/TC 44/SC 3 via your national standards body. A complete listing of these bodies can be

Introduction
This International Standard has been prepared with the assistance of Commission II of the International
Institute of Welding (IIW).
This International Standard has been revised to assist an alignment between the documents prepared by
CEN/TC 121/SC 3 in their work towards a CEN standard for covered electrodes for nickel-base alloys and
those drawn up by Commission II of the IIW. The classifications in the IIW proposals remain largely unaltered,
but the designations now allow for the optional use of a chemical symbol in the form widely favoured in
Europe.
INTERNATIONAL STANDARD ISO 14172:2008(E)
Welding consumables — Covered electrodes for manual metal
arc welding of nickel and nickel alloys — Classification
1 Scope
This International Standard prescribes requirements for the classification of nickel- and nickel-alloy-covered
electrodes for manual metal arc welding and overlaying. It includes those compositions in which the nickel
content exceeds that of any other element.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

3 Classification
A covered electrode shall be classified in accordance with the chemical composition of the all-weld metal as
given in Table 1 and the mechanical properties listed in Table 2. The symbol for the classification is divided
into two parts:
a) the first part gives a symbol indicating the product/process to be used;
b) the second part gives a symbol indicating the chemical composition of the all-weld metal.
4 Symbols and requirements
4.1 Symbol for the product/process
The symbol for covered electrodes used for manual metal arc welding shall be the letter “E”.
ISO 14172:2008(E)
4.2 Symbol for the chemical composition of the all-weld metal
The symbol for the chemical composition of the all-weld metal shall comprise “Ni” plus four digits, as shown in
Table 1. The first digit is an indicator of the class of alloy deposited, where
⎯ 2 indicates no significant alloy addition,
⎯ 4 indicates significant coppe
