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 24598 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 24598:2007), which has been technically
revised.
The main changes compared to the previous edition are:
a) the composition of 9C1MV is modified on the B side of Table 3 (former Table 4) and Table 4 (former
Table 5);
b) different test pieces in accordance with ISO 15792-1 are specified for side A and B in Clauses 5A and 5B,
respectively.
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
found at www.iso.org.

ISO 24598:2012(E)
Introduction
This International Standard recognizes that there are two somewhat different approaches in the global market
to classifying a given wire electrode, tubular cored electrode or electrode/flux combination, and allows for
either or both to be used to suit a particular market need. Application of either type of classification
designation (or of both where suitable) identifies a product as classified in accordance with this International
[2]
Standard. The classification in accordance with system A is mainly based on EN 12070:1999 . The
classification in accordance with system B is mainly based upon standards used around the Pacific Rim.
This International Standard provides a classification system for solid wire electrodes in terms of their chemical
composition, solid wire electrodes and tubular cored electrodes in terms of the deposit composition obtained
with a particular submerged arc flux and, where required, electrode-flux combinations in terms of the yield
strength, tensile strength and elongation of the all-weld metal deposit. The ratio of yield to tensile strength of
weld metal is generally higher than that of parent metal. Users should note that matching weld metal yield
strength to parent metal yield strength does not necessarily ensure that the weld metal tensile strength
matches that of the parent material. Where the application requires matching tensile strength, therefore,
selection of the consumable should be made by reference to column 3 of Table 1A or Table 1B, as
appropriate.
Although combinations of wire electrodes and fluxes supplied by individual companies can have the same
classification, the individual wire electrodes and fluxes from different companies are not interchangeable
unless verified in accordance with this International Standard.
It should be noted that the mechanical properties of all-weld metal test pieces used to classify the wire
electrodes vary from those obtained in production joints because of differences in welding procedure, such as
electrode size, welding position and material composition.
