Destructive tests on welds in metallic materials - Bend tests (ISO 5173:2009)

This International Standard specifies a method for making transverse root, face and side bend tests on test specimens taken from butt welds, butt welds with cladding (subdivided into welds in clad plates and clad welds) and cladding without butt welds, in order to assess ductility and/or absence of imperfections on or near the surface of the test specimen. It also gives the dimensions of the test specimen. In addition, this International Standard specifies a method for making longitudinal root and face bend tests to be used instead of transverse bend tests for heterogeneous assemblies when base materials and/or filler metal have a significant difference in their physical and mechanical properties in relation to bending. This International Standard applies to metallic materials in all forms of product with welded joints made by any fusion arc welding process.

Zerstörende Prüfungen von Schweißnähten an metallischen Werkstoffen - Biegeprüfungen (ISO 5173:2009)

Diese Internationale Norm legt ein Verfahren zur Durchführung von wurzelseitigen, oberseitigen Quer- und Seitenbiegeprüfungen an Probestücken aus Stumpfnähten, Stumpfnähten mit Plattierung (unterteilt in Schweißungen in Plattierungsblechen und in Plattierungsschweißnähten) und Plattierung ohne Stumpfnähte fest, um die Dehnbarkeit und/oder das Fehlen von Unregelmäßigkeiten an oder nahe der Oberfläche des Probestücks zu beurteilen. Sie gibt ebenso die Maße des Probestücks an.
Darüber hinaus legt diese Internationale Norm ein Verfahren zur Durchführung von wurzelseitigen und oberseitigen Längsbiegeprüfungen fest, die an Stelle der Querbiegeprüfungen für heterogene Komponenten eingesetzt werden, wenn Grundwerkstoffe und/oder Schweißzusatz deutliche Unterschiede in ihre physikalischen und mechanischen Eigenschaften hinsichtlich der Biegung besitzen.
Diese Internationale Norm gilt für Metallwerkstoffe jeglicher Produktform mit Schweißverbindungen, die mit jeder Art von Lichtbogen-Schmelzschweißverfahren erzeugt werden.

Essais destructifs des soudures sur matériaux métalliques - Essais de pliage (ISO 5173:2009)

L'ISO 5173:2009 spécifie une méthode d'essai de pliage transversal envers, endroit et de côté sur des éprouvettes prélevées dans des soudures bout à bout, des soudures bout à bout avec revêtement (subdivisées en soudures de tôles revêtues et soudures de revêtement) et revêtement sans soudure bout à bout, afin d'évaluer la ductilité et/ou l'absence d'imperfections sur la surface ou près de la surface de l'éprouvette. Elle spécifie également les dimensions de l'éprouvette.
De plus, l'ISO 5173:2009 spécifie une méthode d'essai de pliage longitudinal envers et endroit à utiliser au lieu des pliages transversaux pour les assemblages hétérogènes dont les métaux de base et/ou le métal d'apport ont des différences notables de propriétés physiques et mécaniques concernant le pliage.
L'ISO 5173:2009 est applicable à des assemblages soudés sur matériaux métalliques sous toute forme de livraison quel que soit le procédé de soudage par fusion utilisé.

Porušitveno preskušanje zvarnih spojev na kovinskih materialih - Upogibni preskusi (ISO 5173:2009)

Ta mednarodni standard določa metodo za opravljanje prečnih, sprednjih in stranskih upogibnih preskusov na preskusnih vzorcih, vzetih iz soležnih zvarov, soležnih zvarov z oblogo (razdeljenih v zvare v ploščah za oblogo in navare) in oblog brez soležnih zvarov, z namenom oceniti  preoblikovalnost in/ali odsotnost pomanjkljivosti na ali v bližini površine preskusnega vzorca. Prav tako podaja mere preskusnega vzorca. Poleg tega ta mednarodni standard določa metodo za opravljanje vzdolžnih upogibnih preskusov na korenu in sprednji strani, ki se uporabljajo namesto prečnih upogibnih preskusov za heterogene sklope, kadar imajo osnovni materiali in/ali kovina za polnjenje znatno razliko v fizikalnih in mehanskih lastnostih glede upogibanja. Ta mednarodni standard se uporablja za kovinske materiale v vseh oblikah izdelkov z zvarnimi spoji, ki so spojeni s kakršnimkoli postopkom obločnega varjenja.

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 5173 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 5, Testing and inspection of welds.
This third edition cancels and replaces the second edition (ISO 5173:2000) 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 5 via your national standards body, of which a complete listing can be found at

INTERNATIONAL STANDARD ISO 5173:2009(E)

Destructive tests on welds in metallic materials — Bend tests
1 Scope
This International Standard specifies a method for making transverse root, face and side bend tests on test
specimens taken from butt welds, butt welds with cladding (subdivided into welds in clad plates and clad

the surface of the test specimen. It also gives the dimensions of the test specimen.
In addition, this International Standard specifies a method for making longitudinal root and face bend tests to
be used instead of transverse bend tests for heterogeneous assemblies when base materials and/or filler
metal have a significant difference in their physical and mechanical properties in relation to bending.
This International Standard applies to metallic materials in all forms of product with welded joints made by any
