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).

INTERNATIONAL STANDARD ISO 14172:2015(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 documents, in whole or in part, are normatively referenced in this document and are

indispensable for its application. For dated references, only the edition cited applies. For undated

references, the latest edition of the referenced document (including any amendments) applies.

ISO 544, Welding consumables — Technical delivery conditions for filler materials and fluxes — Type of

product, dimensions, tolerances and markings

ISO 6847, Welding consumables — Deposition of a weld metal pad for chemical analysis

ISO 14344, Welding consumables — Procurement of filler materials and fluxes

ISO 15792-1:2000, Welding consumables — Test methods — Part 1: Test methods for all-weld metal test

specimens in steel, nickel and nickel alloys. Amended by ISO 15792-1:2000/Amd 1:2011.

ISO 80000-1:2009, Quantities and units — Part 1: General
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 2015 – All rights reserved 1
---------------------- Page: 11 ----------------------
SIST EN ISO 14172:2015
ISO 14172:2015(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 (nick-

el-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 procedure

For purposes of determining compliance with the requirements of this International Standard, the

actual test values obtained shall be subject to ISO 80000-1:2009, B.3, 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 arithmetic average value is to be compared to the requirements of this International Standard,

rounding shall be done only after calculating the arithmetic average. If the test method cited in Clause 2

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 can 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 assembly type 1.3 in accordance with ISO 15792-1:2000 with

4,0 mm electrodes. 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 can 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.

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” can cause confusion with the European “EN”

standards prepared by CEN, “Ni” has been adopted for the se
