Welding consumables - Covered electrodes for manual metal arc welding of creep-resisting steels - Classification (ISO 3580:2017)
This document specifies requirements for classification of covered electrodes, based on the all-weld
metal in the heat-treated condition, for manual metal arc welding of ferritic and martensitic creepresisting
and low alloy elevated temperature steels.
This document is a combined specification for classification utilizing a system based upon the chemical
composition of the all-weld metal, with requirements for the yield strength and impact energy of the
all-weld metal, or utilizing a system based upon the tensile strength and the chemical composition of
the all-weld metal.
a) Paragraphs and tables which carry the suffix letter “A” are applicable only to electrodes classified
to the system based upon chemical composition, with requirements for the yield strength and
impact energy of the all-weld metal under this document.
b) Paragraphs and tables which carry the suffix letter “B” are applicable only to electrodes classified
to the system based upon the tensile strength and the chemical composition of all-weld metal under
this document.
c) Paragraphs and tables which do not have either the suffix letter “A” or the suffix letter “B” are
applicable to all covered electrodes classified under this document.
For comparison purposes, some tables include requirements for electrodes classified according to 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, and/or its
packaging, can be marked with the classification in either or both systems.
Schweißzusätze - Umhüllte Stabelektroden zum Lichtbogenhandschweißen von warmfesten Stählen - Einteilung (ISO 3580:2017)
Diese Internationale Norm legt Anforderungen für die Einteilung von umhüllten Stabelektroden zum Licht-bogen¬handschweißen von ferritischen und martensitischen warmfesten Stählen sowie niedrig legierten Stählen für erhöhte Temperatur fest, basierend auf dem reinen Schweißgut nach Wärmebehandlung.
Diese Internationale Norm enthält eine gemeinsame Spezifikation zur Einteilung nach der chemischen Zu-sammensetzung des reinen Schweißgutes mit Anforderungen an Streckgrenze und Kerbschlagarbeit des reinen Schweißgutes oder nach der Zugfestigkeit und der chemischen Zusammensetzung des reinen Schwei߬gutes.
a) Abschnitte und Tabellen, gekennzeichnet durch ein nachgestelltes „A“, können nur für Stabelektroden angewendet werden, die nach der chemischen Zusammensetzung und Anforderungen an Streckgrenze und Kerbschlagarbeit des reinen Schweißgutes nach dieser Internationalen Norm eingeteilt werden.
b) Abschnitte und Tabellen, gekennzeichnet durch ein nachgestelltes „B“, können nur für Stabelektroden angewendet werden, die nach der Zugfestigkeit und der chemischen Zusammensetzung des reinen Schweißgutes nach dieser Internationalen Norm eingeteilt werden.
c) Abschnitte und Tabellen, die kein nachgestelltes „A“ oder „B“ enthalten, sind für alle nach dieser Inter-nationalen Norm eingeteilten Stabelektroden anwendbar.
In einigen Tabellen sind zum Vergleich die Anforderungen an Stabelektroden nach den beiden Norm-systemen zusammengestellt. In Zusammensetzung und Eigenschaften ähnliche Stabelektroden aus beiden Systemen werden in der betreffenden Tabelle in derselben Zeile in benachbarten Spalten aufgeführt. Die eine Spalte enthält das für das eine System verbindliche Kurzzeichen, die andere Spalte in Klammern das für die ähnliche Stabelektrode geltende Kurzzeichen nach dem anderen System. Durch geeignete An-passung ist es oft, aber nicht immer, möglich, eine Stabelektrode herzustellen, die nach beiden Systemen ein¬geteilt werden kann. Dann darf die Stabelektrode und/oder ihre Verpackung mit der Einteilung nach einem oder nach beiden Systemen gekennzeichnet werden.
Produits consommables pour le soudage - Électrodes enrobées pour le soudage manuel à l'arc des aciers résistant au fluage - Classification (ISO 3580:2017)
L'ISO 3580:2017 spécifie les exigences relatives à la classification des électrodes enrobées, d'après le métal fondu hors dilution à l'état traité thermiquement, pour le soudage manuel à l'arc des aciers ferritiques et martensitiques résistant au fluage et des aciers faiblement alliés pour usage à haute température.
L'ISO 3580:2017 propose une spécification mixte permettant une classification utilisant un système fondé soit sur la composition chimique du métal fondu hors dilution, avec des exigences portant sur la limite d'élasticité et l'énergie de rupture pour le métal fondu hors dilution, soit sur la résistance à la traction et la composition chimique du métal fondu hors dilution.
a) Les paragraphes et les tableaux portant le suffixe «A» sont applicables uniquement aux électrodes enrobées classifiées d'après le système basé sur la composition chimique, avec des exigences portant sur la limite d'élasticité et l'énergie de rupture pour le métal fondu hors dilution conformément au présent document.
b) 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 la composition chimique du métal fondu hors dilution conformément au présent document.
c) Les paragraphes et les tableaux ne portant ni le suffixe «A» ni le suffixe «B» sont applicables à toutes les électrodes enrobées classifiées conformément à l'ISO 3580:2017.
Afin de permettre des comparaisons, certains tableaux comportent des exigences relatives aux électrodes classifiées selon les deux systèmes, ce qui place des électrodes particulières, ayant des compositions et des propriétés similaires des deux systèmes, sur des lignes adjacentes de ces tableaux. Sur une ligne particulière du tableau ayant un caractère obligatoire dans l'un des systèmes, le symbole affecté à l'électrode similaire de l'autre système figure entre parenthèses. En restreignant de façon adéquate la formulation d'une électrode donnée, il est souvent possible, mais pas toujours, de fabriquer une électrode pouvant être classifiée dans les deux systèmes, auquel cas l'électrode et/ou son emballage peut être marqué de la classification suivant l'un ou l'autre des deux systèmes, ou suivant les deux.

Introduction
This document proposes a method for classification of covered electrodes, in terms of chemical
composition of the all-weld metal (system A) and in terms of tensile strength and chemical composition
(system B).
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 electrode
diameter, width of weave, welding position and material composition.
[ ]
The classification according to system A is mainly based on EN 1599 1 . The classification according to
system B is mainly based upon standards used around the Pacific Rim.

1 Scope
This document specifies requirements for classification of covered electrodes, based on the all-weld
metal in the heat-treated condition, for manual metal arc welding of ferritic and martensitic creep-
resisting and low alloy elevated temperature steels.
This document is a combined specification for classification utilizing a system based upon the chemical
composition of the all-weld metal, with requirements for the yield strength and impact energy of the
all-weld metal, or utilizing a system based upon the tensile strength and the chemical composition of
the all-weld metal.
a) Paragraphs and tables which carry the suffix letter “A” are applicable only to electrodes classified

4 Classification
Classification designations are based upon two approaches to indicate the composition and properties
of the all-weld metal obtained with a given electrode. The two designation approaches include
additional designators for some other classification requirements, but not all. In most cases, a given
commercial product can be classified in both systems. Then either or both classification designations
can be used for the product.
The classification includes all-weld metal properties obtained with a covered electrode as given in 4A
and 4B. The classification is based on the electrode size 4,0 mm with the exception of the symbol for
welding position which is based on ISO 15792-3.
4A Classification by chemical composition 4B Classification by tensile strength and
chemical composition
The classification is divided into six parts. The classification is divided into five parts.
1) The first part gives a symbol indicating the 1) The first part gives a symbol indicating the
