Mechanical joining - Destructive testing of joints - Specimen dimensions and test procedure for tensile shear testing of single joints (ISO 12996:2013)
ISO 12996:2013 specifies the geometry of the test specimens and the procedure for the tensile shear testing of single mechanical joints on single and multilayer specimens up to a single sheet thickness of 4,5 mm.
The term sheet, as used in ISO 12996:2013, includes extrusions and cast materials.
The purpose of the tensile shear test is to determine the mechanical characteristics and failure modes of the joints made with the different methods.
ISO 12996:2013 does not apply to civil engineering applications such as metal building and steel construction which are covered by other applicable standards.
Mechanisches Fügen - Zerstörende Prüfung von Verbindungen - Probenmaße und Prüfverfahren für die Scherzugprüfung von Einpunktproben (ISO 12996:2013)
Diese Internationale Norm enthält Festlegungen für die Probengeometrie und das Verfahren für die Scherzugprüfung von Einpunktverbindungen an ein- und mehrlagigen Proben bis zu einer Dicke eines einzelnen Bleches von 4,5 mm fest.
Der Begriff Blech, so wie er in dieser Internationalen Norm verwendet wird, umfasst extrudierte Werkstoffe und Gusswerkstoffe.
Das Ziel der Scherzugprüfung ist, die mechanischen Kennwerte und die Versagensarten der mit unterschiedlichen Verfahren hergestellten Verbindungen zu bestimmen.
Diese Norm soll nicht im Hochbau angewendet werden, wie z. B. für Bauten aus Metall und Stahl-konstruktionen, die durch andere anwendbare Normen abgedeckt werden.
Assemblage mécanique - Essais destructifs des jonctions - Dimensions des éprouvettes et procédures d'essai pour essais de traction-cisaillement des jonctions uniques (ISO 12996:2013)
L'ISO 12996:2013 spécifie la géométrie des éprouvettes et le mode opératoire pour les essais de traction-cisaillement des assemblages mécaniques simples sur des éprouvettes mono et multicouches jusqu'à une épaisseur de tôle individuelle de 4,5 mm.
Le terme « tôle », tel qu'il est employé dans l'ISO 12996:2013, comprend les matériaux extrudés et les matériaux de fonderie.
L'essai de traction-cisaillement a pour objet de déterminer les caractéristiques mécaniques et les types de défaillances des assemblages réalisés selon les différentes méthodes.
L'ISO 12996:2013 ne s'applique pas aux applications de génie civil telles que la construction métallique et la construction en acier qui sont couvertes par d'autres normes.
Mehansko spajanje - Porušitveno preskušanje spojev - Mere primerkov in preskusni postopki za natezno strižno preskušanje enojnih spojev (ISO 12996:2013)
Ta mednarodni standard določa geometrijo preskusnih vzorcev ter postopek za natezno strižno preskušanje posameznih mehanskih spojev na eno- in večplastnih vzorcih do debeline posamezne plasti 4,5 mm. Izraz plast, uporabljen v tem mednarodnem standardu, vključuje materiale za ekstrudiranje in vlivanje. Namen natezno strižnega preskušanja je določiti mehanske lastnosti in napake spojev, izdelanih z različnimi metodami. Ta mednarodni standard ne velja za proizvode za inženirske objekte, kot so kovinske stavbe in jeklene konstrukcije, ki jih zajemajo drugi ustrezni standardi.

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.

For the purpose of this document, the following terms and definitions apply.

slope of the force curve, energy dissipation W (see 3.8), can be determined according to the shear diagram given
in Figure 4.

e
force where predetermined plastic or permanent displacement of the test specimen occurs
3.3
slippage force

s
force at which a relative movement of the joined parts is registered

3.4
displacement
s
change in the length of a specimen due to the application of a force

Note 1 to entry: The 0,3F limit was introduced in order to reduce the time for carrying out the tensile shear
max
test, because generally the area under the force curve after 0,3F does not contribute significantly to the
max
dissipated energy.

property of a joint in which the transmission of external forces, in particular shear forces, is effected by
geometrical elements which prevent the movement of the components relative to one another
