Welding consumables - Covered electrodes for manual metal arc welding of non-alloy and fine grain steels - Classification (ISO 2560:2020)
This document specifies requirements for the 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.
This document is a combined specification providing for classification utilizing a system based on the yield strength and the average impact energy of 47 J of all-weld metal, or utilizing a system based on the tensile strength and the average impact energy of 27 J of all-weld metal.
a) Clauses, subclauses and tables which carry the suffix letter "A" are applicable only to covered electrodes classified to the system based on the yield strength and the average impact energy of 47 J of all weld metal in this document.
b) Clauses, subclauses and tables which carry the suffix letter "B" are applicable only to covered electrodes classified to the system based on the tensile strength and the average impact energy of 27 J of all weld metal in this document.
c) Clauses, subclauses and tables which do not have either the suffix letter "A" or the suffix letter "B" are applicable to all covered electrodes classified in this document.

Le présent document 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.
Le présent document 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.
a) Les articles, les paragraphes 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 le présent document.
b) Les articles, les paragraphes 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 le présent document.
c) Les articles, les paragraphes et les tableaux ne comportant ni le suffixe «A» ni le suffixe «B» sont applicables à toutes les électrodes enrobées classifiées conformément au présent document.

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).
