Welding consumables - Covered electrodes for manual metal arc welding of non-alloy and fine grain steels - Classification (ISO 2560:2009)
ISO 2560:2009 specifies requirements for classification of covered electrodes and deposited metal in the as-welded condition and in the post-weld heat-treated condition for manual metal arc welding of non-alloy and fine grain steels with a minimum yield strength of up to 500 MPa or a minimum tensile strength of up to 570 MPa.
ISO 2560:2009 is a combined specification providing for classification utilizing a system based upon the yield strength and the average impact energy of 47 J of all-weld metal, or utilizing a system based upon the tensile strength and the average impact energy of 27 J of all-weld metal.
Paragraphs and tables which carry the suffix letter “A” are applicable only to covered electrodes classified to the system based upon the yield strength and the average impact energy of 47 J of all‑weld metal in ISO 2560:2009.
Paragraphs and tables which carry the suffix letter “B” are applicable only to covered electrodes classified to the system based upon the tensile strength and the average impact energy of 27 J of all‑weld metal in ISO 2560:2009.
Paragraphs and tables which do not have either the suffix letter “A” or the suffix letter “B” are applicable to all covered electrodes classified in ISO 2560:2009.

Produits consommables pour le soudage - Électrodes enrobées pour le soudage manuel à l'arc des aciers non alliés et des aciers à grains fins - Classification (ISO 2560:2009)
L'ISO 2560:2009 spécifie les exigences relatives à la classification des électrodes enrobées et du métal déposé à l'état brut de soudage ou traité thermiquement après soudage, en soudage manuel à l'arc des aciers non alliés et des aciers à grains fins ayant une limite d'élasticité minimale pouvant atteindre 500 MPa ou une résistance à la traction minimale pouvant atteindre 570 MPa.
L'ISO 2560:2009 propose une spécification mixte permettant une classification utilisant un système basé soit sur la limite d'élasticité et l'énergie de rupture moyenne de 47 J pour le métal fondu hors dilution, soit sur la résistance à la traction et l'énergie de rupture moyenne de 27 J pour le métal fondu hors dilution.
Les alinéas et les tableaux portant le suffixe «A» sont applicables uniquement aux électrodes enrobées classifiées d'après le système basé sur la limite d'élasticité et l'énergie de rupture moyenne de 47 J pour le métal fondu hors dilution dans l'ISO 2560:2009.
Les alinéas et les tableaux portant le suffixe «B» sont applicables uniquement aux électrodes enrobées classifiées d'après le système basé sur la résistance à la traction et l'énergie de rupture moyenne de 27 J pour le métal fondu hors dilution dans l'ISO 2560:2009.
Les alinéas et les tableaux ne comportant ni le suffixe «A» ni le suffixe «B» sont applicables à toutes les électrodes enrobées classifiées conformément à l'ISO 2560:2009.

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 2560 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 3, Welding consumables.
This third edition cancels and replaces the second edition (ISO 2560:2002), which has been technically
revised.
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 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 in accordance with this International Standard. The classification in accordance with system A is
[1]
mainly based on EN 499:1994 . The classification in accordance with 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 strength 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 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 vary from those obtained in production joints because of differences in welding procedure such as
...
