(Main)Welding consumables - Solid wire electrodes, tubular cored electrodes and electrode-flux combinations for submerged arc welding of high strength steels - Classification (ISO 26304:2017)
Welding consumables - Solid wire electrodes, tubular cored electrodes and electrode-flux combinations for submerged arc welding of high strength steels - Classification (ISO 26304:2017)
ISO 26304:2017 specifies requirements for classification of solid wire electrodes, tubular cored electrodes, and electrode-flux combinations (the all-weld metal deposits) in the as-welded condition and in the post-weld heat-treated condition for submerged arc welding of high strength steels with a minimum yield strength greater than 500 MPa or a minimum tensile strength greater than 570 MPa. One flux can be tested and classified with different electrodes. One electrode can be tested and classified with different fluxes. The solid wire electrode is also classified separately based on its chemical composition.
This document is a combined specification providing for classification utilizing a system based on the yield strength and average impact energy of 47 J for the all-weld metal, or utilizing a system based on the tensile strength and average impact energy of 27 J for the all-weld metal.
a) Clauses, subclauses and tables which carry the suffix letter "A" are applicable only to solid wire electrodes, tubular cored electrodes and the all-weld metal deposits classified to the system based on the yield strength and the average impact energy of 47 J for the all-weld metal obtained with electrode-flux combinations in accordance with this document.
b) Clauses, subclauses and tables which carry the suffix letter "B" are applicable only to solid wire electrodes, tubular cored electrodes and the all-weld metal deposits classified to the system based on the tensile strength and the average impact energy of 27 J for the all-weld metal obtained with electrode-flux combinations in accordance with 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 solid wire electrodes, tubular cored electrodes and electrode-flux combinations classified in accordance with this document.
For comparison purposes, some tables include requirements for electrodes classified in accordance with both systems, placing individual electrodes from the two systems, which are similar in composition and properties, on adjacent lines in the particular table. In a particular line of the table that is mandatory in one system, the symbol for the similar electrode from the other system is indicated in parentheses. By appropriate restriction of the formulation of a particular electrode, it is often, but not always, possible to produce an electrode that can be classified in both systems, in which case the electrode, or its packaging, can be marked with the classification in either or both systems.

Produits consommables pour le soudage - Fils-électrodes pleins, fils-électrodes fourrés et couples électrodes-flux pour le soudage à l'arc sous flux des aciers à haute résistance - Classification (ISO 26304:2017)
ISO 26304:2017 spécifie les exigences relatives à la classification des fils-électrodes pleins, des fils-électrodes fourrés et des couples fils-flux (dépôts en métal fondu hors dilution) à l'état brut de soudage ou après traitement thermique après soudage des aciers à haute résistance ayant une limite d'élasticité minimale supérieure à 500 MPa ou une résistance à la traction minimale supérieure à 570 MPa. Un flux peut être soumis à essai et être classifié avec différents fils-électrodes. Un fil-électrode peut être soumis à essai et être classifié avec différents flux. Le fil-électrode plein est également classifié séparément d'après sa composition chimique.
La présente Norme internationale constitue 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 qui portent le suffixe «A» ne sont applicables qu'aux fils-électrodes pleins, aux fils-électrodes fourrés et dépôts en métal fondu hors dilution classifiés 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 obtenu avec des couples fils-flux conformément à la présente Norme internationale.
b) Les articles, les paragraphes et les tableaux qui portent le suffixe «B» ne sont applicables qu'aux fils-électrodes pleins, aux fils-électrodes fourrés et dépôts en métal fondu hors dilution classifiés 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 obtenu avec des couples fils-flux conformément à la présente Norme internationale.
c) Les articles, les paragraphes et les tableaux qui ne portent ni le suffixe «A» ni le suffixe «B» sont applicables à tous les fils-électrodes pleins, fils-électrodes fourrés et couples fil-flux classifiés conformément à la présente Norme internationale.
À des fins de comparaison, certains tableaux comportent des exigences pour des électrodes classifiées selon les deux systèmes, en plaçant des électrodes individuelles issues des deux systèmes, semblables en composition et en propriétés, sur des lignes adjacentes du tableau particulier. Sur une ligne particulière du tableau, obligatoire pour un système, le symbole pour l'électrode semblable dans l'autre système est indiqué entre parenthèses. Selon une restriction appropriée de la formulation d'une électrode particulière, il est souvent mais pas toujours possible de produire une électrode qui peut être classifiée selon les deux systèmes, auquel cas l'électrode, ou son emballage, peut être marquée avec la classification de l'un ou l'autre système.
Dodajni materiali za varjenje - Masivne žice, strženske žice in kombinacije žic in praškov za obločno varjenje visokotrdnostnih jekel pod praškom - Razvrstitev (ISO 26304:2017)
Ta dokument določa zahteve za razvrstitev masivnih žic, strženskih žic ter kombinacij žic in praškov (čisti vari), ki so namenjeni obločnemu varjenju visokotrdnostnih jekel pod praškom, v varjenem stanju in stanju po varjenju s toplotno obdelavo z minimalno mejo prožnosti več kot 500 MPa ali minimalno natezno trdnostjo več kot 570 MPa. En prašek je mogoče preskušati in razvrstiti z različnimi elektrodami. Eno elektrodo je mogoče preskušati in razvrstiti z različnimi praški. Masivna žica je razvrščena ločeno na podlagi kemične sestave.
Ta dokument je združena specifikacija, ki določa razvrstitev po sistemu na osnovi meje prožnosti in povprečne energije udarca 47 J za čiste vare ali po sistemu na osnovi natezne trdnosti in povprečne energije udarca 27 J za čiste vare.
a) Točke, podtočke in preglednice z dodano črko »A« se uporabljajo samo za masivne žice, strženske žice ter čiste vare, ki so razvrščeni po sistemu na osnovi meje prožnosti in povprečni energiji udarca 47 J za čiste vare, pridobljene s kombinacijami žic in praška v skladu s tem dokumentom.
b) Točke, podtočke in preglednice z dodano črko »B« se uporabljajo samo za masivne žice, strženske žice ter čiste vare, ki so razvrščeni po sistemu na osnovi natezne trdnosti in povprečne energije udarca 27 J za čiste vare, pridobljene s kombinacijami žic in praška v skladu s tem dokumentom.
c) Točke, podtočke in preglednice brez dodane črke »A« ali »B« se uporabljajo za vse masivne žice, strženske žice ter kombinacije žic in praškov, ki so razvrščene v skladu s tem dokumentom.
Za namene primerjave nekatere preglednice vključujejo zahteve za elektrode, ki so razvrščene v skladu z obema sistemoma, pri čemer so posamezne elektrode iz dveh sistemov, ki so si podobne po sestavi in lastnostih, navedene v sosednjih vrsticah v posamezni preglednici. V posamezni vrstici preglednice, ki je obvezna za en sistem, je simbol za podobno elektrodo iz drugega sistema naveden v navednicah. Z ustrezno omejitvijo formulacije posamezne elektrode je pogosto, vendar ne vedno, mogoče
izdelati elektrodo, ki jo je mogoče uvrstiti v oba sistema. V tem primeru se elektrodo ali njeno embalažo lahko označi s simboli za razvrstitev v enega ali oba sistema.

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).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
