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.
ISO 31-0:1992, Quantities and units — Part 0: General principles
ISO 544, Welding consumables — Technical delivery conditions for welding filler materials — Type of product,
dimensions, tolerances and markings
ISO 6847, Welding consumables — Deposition of a weld metal pad for chemical analysis
ISO 14344, Welding and allied processes — Flux and gas shielded electrical welding processes —
Procurement guidelines for consumables
ISO 15792-1:2000, Welding consumables — Test methods — Part 1: Test methods for all-weld metal test
specimens in steel, nickel and nickel alloys
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 2008 – All rights reserved 1
---------------------- Page: 13 ----------------------
SIST EN ISO 14172:2009
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 copper addition (nickel-copper alloys),
⎯ 6 indicates significant chromium addition, with iron less than 25 % (nickel-chromium-iron and nickel-
chromium-molybdenum alloys),
⎯ 8 indicates significant chromium addition, with iron more than 25 % (nickel-iron-chromium alloys),
⎯ 10 indicates significant molybdenum addition without significant chromium addition (nickel-molybdenum
alloys).
The remaining digits indicate the particular alloy deposited. The basis of the system of designation is
described in Annex A.
NOTE In addition, the chemical symbol can be used.
4.3 Rounding-off procedure
For the purposes of determining compliance with the requirements of this International Standard, the actual
test values obtained shall be rounded using ISO 31-0:1992, Annex B, Rule A. If the measured values are
obtained by equipment calibrated in units other than those of this International Standard, the measured values
shall be converted to the units of this International Standard before rounding. If an average value is to be
compared to the requirements of this International Standard, rounding shall be done only after calculating the
average. In the case where the test method standard cited in the normative references of this International
Standard contains instructions for rounding that conflict with the instructions of this International Standard, the
rounding requirements of the test method standard shall apply. The rounded results shall fulfil the
requirements of the appropriate table for the classification under test.
5 Chemical analysis
Chemical analysis shall be performed on any suitable all-weld metal test specimen. In case of dispute, the test
specimen specified in ISO 6847 shall be used. The test results shall meet the requirements of Table 1 for the
classification under test. Any analytical technique may be used, but, in case of dispute, reference shall be
made to established published methods.
6 Mechanical properties of the all-weld metal
Mechanical properties are not part of the designation, but they are required for classification. The mechanical
properties of the all-weld metal, deposited using covered electrodes in accordance with Table 1, shall be
determined using a test coupon in accordance with ISO 15792-1:2000, type 1.0. The minimum tensile
properties shall be in accordance with Table 2.
7 Retests
If any test fails to meet the requirement, that test shall be repeated twice. The results of both retests shall
meet the requirements. Specimens for retesting may be taken from the original test assembly or from a new
test assembly. For chemical analysis, retests need only be for those specific elements that failed to meet their
test requirement. If the results of one or both retests fail to meet the requirement, the material under test shall
be considered not to meet the requirements of this International Standard for that classification.

SIST EN ISO 14172:2009
ISO 14172:2008(E)
In the event that, during preparation or after completion of any test, it is clearly determined that prescribed or
proper procedures were not followed in preparing the weld test assembly or test specimen(s) or in conducting
the tests, the test shall be considered invalid, without regard to whether the test was actually completed, or
whether the test results met, or failed to meet, the requirement. That test shall be repeated, following proper
prescribed procedures. In this case, the requirement for doubling the number of test specimens does not
apply.
8 Technical delivery conditions
Technical delivery conditions shall meet the requirements of ISO 544 and ISO 14344.
9 Designation
The designation of covered electrodes shall follow the principle given in the example below.
EXAMPLE A covered electrode for manual metal arc welding (E) depositing a nickel-base alloy weld metal (Ni) with
a chemical composition of 67 % Ni, 15 % Cr, 7 % Mn and 2 % Nb and all other requirements for the alloy 6182 in Table 1
is designated
Covered electrode ISO 14172 - E Ni 6182
or alternatively
Covered electrode ISO 14172 - E Ni 6182 (NiCr15Fe6Mn)
where
ISO 14172 designates the number of this International Standard;
E designates covered electrode/manual metal arc welding (see 4.1);
Ni 6182 designates the chemical composition of all-weld metal (Table 1);
NiCr15Fe6Mn designates the optional chemical symbol of the covered electrode (see Table 1).

Annex A
(informative)
System for designation of welding filler metals
The designations used in this International Standard derive from the project of the International Institute of
Welding described in Reference [5], and subsequently updated and published in References [6] and [7]. See
also Reference [8]. The aim is to develop internationally accepted designations for welding filler metals, since
national designation systems are not readily changed and a generic system will allow comparability among the
various national specifications.
The system provides for one or two initial alpha designators, the first letter describing the type of filler metal
and the second letter describing the alloy system. A four-digit numeric designator follows the initial letters and,
for a number of alloy filler metals, this designator is similar to those assigned by the Unified Numbering
System (UNS). In this way, the filler metals are frequently related to the base metals with which they are often
used (see Annex B).
The system as proposed uses “E” as the initial alpha designator for covered electrodes and “N” for nickel-base
alloys. However, because the combination “EN” may cause confusion with the European “EN” standards
prepared by CEN, “Ni” has been adopted for the second alpha designator.
