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 3.
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 International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 2560 was prepared in collaboration with the International Institute of Welding which has been approved by the
ISO Council as an international standardizing body in the field of welding.
This second edition cancels and replaces the first edition (ISO 2560:1973), which has been technically revised.
Annexes A to D of this International Standard are for information only.

Introduction
This International Standard recognizes that there are two somewhat different approaches in the global market to
classifying a given electrode, 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 according to
this International Standard. The classification according to system A is mainly based on EN 499. The classification
according to system B is mainly based upon standards used around the Pacific Rim.
This International Standard provides a classification in order to designate covered electrodes in terms of the yield
strength, tensile strength and elongation of the all-weld metal. 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 will not necessarily ensure that the weld metal tensile strength matches that of the parent
metal. Therefore, where the application requires matching tensile strength, selection of the consumable should be
made by reference to column 3 of Table 1A or to Table 1B and Table 8B.
It should be noted that the mechanical properties of all-weld metal test specimens used to classify the 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.
Requests for official interpretation of any aspect of this International Standard should be directed to the Secretariat
of ISO/TC 44/SC 3 via the member body in the user's country, a complete listing of which can be found at
www.iso.org.
