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.

Introduction
This International Standard provides a classification system for tubular cored electrodes in terms of chemical
composition of the all-weld metal, type of electrode core, type of shielding gas and welding position, or in
terms of the tensile properties, chemical composition of the all-weld metal, usability characteristics of the
electrodes, shielding gas and welding position. The ratio of proof to tensile strength of weld metal is generally
higher than that of parent metal. Users should note that matching weld metal proof strength to parent metal
proof strength will not necessarily ensure that the weld metal tensile strength matches that of the parent metal.
Where the application requires matching tensile strength, therefore, selection of the consumable should be
made by reference to column 4 of Table 2.
It should be noted that the mechanical properties of all-weld metal test specimens used to classify the tubular
cored electrodes will vary from those obtained in production joints because of differences in welding
procedure such as electrode size, width of weave, welding position and parent metal composition.
The classification according to system A is mainly based on EN 12071:1999, Welding consumables —
Tubular cored electrodes for gas shielded metal arc welding of creep-resisting steels — Classification. The
classification according to system B is mainly based upon standards used around the Pacific Rim.
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 which can be found at

Classification
1 Scope
This International Standard specifies requirements for classification of tubular cored electrodes used in the
post-weld heat-treated condition for gas shielded metal arc welding of creep-resisting and low alloy elevated
temperature steels. One tubular cored electrode can be tested and classified with different shielding gases.
This International Standard is a combined specification providing for classification utilizing a system based
upon the chemical composition of all-weld metal or utilizing a system based upon the tensile strength, and the
chemical composition of all-weld metal.
1) Paragraphs and tables which carry the suffix letter “A” are applicable only to tubular cored electrodes
classified to the system based upon chemical composition, with requirements for the yield strength
and the average impact energy of 47 J of all-weld metal in accordance with this International
Standard.
2) Paragraphs and tables which carry the suffix letter “B” are applicable only to tubular cored electrodes
classified to the system based upon the tensile strength and chemical composition of all-weld metal
in accordance with this International Standard.
3) Paragraphs and tables which have neither the suffix letter “A” nor the suffix letter “B” are applicable
to all tubular cored electrodes classified in accordance with this International Standard.
It is recognized that the operating characteristics of tubular cored electrodes can be modified by the use of
pulsed current, but for the purposes of this International Standard, pulsed current is not used for determining
the electrode classification.

3 Classification
Classification designations are based upon two approaches to indicate the chemical composition, the tensile
properties and the impact properties of the all-weld metal obtained with a given electrode. The two designation
approaches include additional designators for some other classification requirements, but not all, as will be
clear from the following sections. In most cases, a given commercial product can be classified in both systems.
Then either or both classification designations can be used for the product.
The classification includes all-weld metal properties obtained with a tubular cored electrode and appropriate
shielding gas combination as given below. With the exception of the symbol for welding position which is
based on ISO 15792-3, the classification is based on the tubular cored electrode size 1,2 mm, or if this is not
manufactured, the next larger diameter manufactured.
3.1A Classification by chemical composition 3.1B Classification by tensile strength and
chemical composition
The classification is divided into six parts:

a
A designation in parentheses [e.g., (CrMo1) or (1CM)] indicates a near match in the other designation system, but not an exact match. The correct designation for a given composition range
is the one without parentheses. A given product may, by having a more restricted chemical composition which fulfils both sets of designation requirements, be assigned both designations
independently, provided that the mechanical property requirements of Table 2 are also satisfied.
b
Single values shown in the table are maximum values.
c
The results shall be rounded to the same number of significant figures as in the specified value using rule A in accordance with Annex B of ISO 31-0:1992 (see 4.8).
d
Cu u 0,3; Nb u 0,1.
e
The weld metal shall be analysed for the specific elements for which values are shown in this table. Other elements listed without specified values shall be reported, if intentionally added.
The total of those latter unspecified elements and all other elements not intentionally added shall not exceed 0,50 %.
f
Nb: 0,02 to 0,10; N: 0,02 to 0,07; Cu: u 0,25; Al: u 0,04.
