Metallic materials - Sheet and strip - Determination of tensile strain hardening exponent (ISO 10275:2007)
EN ISO 10275 specifies a method for determining the tensile strain hardening exponent n of flat products (sheet and strip) made of metallic materials. The method is valid only for that part of the stress-strain curve in the plastic range where the curve is continuous and monotonic (see 7.4). In the case of materials with a serrated stress-strain curve in the work hardening range (materials which show the Portevin-Le Chatelier effect, e.g. AlMg-alloys) the automatic determination (linear regression of the logarithm true stress vs. the logarithm true plastic strain, see 7.7) should be used to give reproducible results.
Metallische Werkstoffe - Blech und Band - Bestimmung des Verfestigungsexponenten im Zugversuch (ISO 10275:2007)
Diese Internationale Norm legt ein Verfahren zur Bestimmung des Verfestigungsexponenten n im Zugversuch von Flacherzeugnissen (Band und Blech) aus metallischen Werkstoffen fest.
Das Verfahren ist nur anwendbar für den plastischen Bereich der Spannung/Dehnung-Kurve, in dem die Kurve kontinuierlich und monoton verläuft (siehe 7.4).
Bei Werkstoffen mit gezackter Spannung/Dehnung-Kurve im Verfestigungsbereich (Werkstoffe mit Portevin-Le Chatelier Effekt, z. B. AlMg-Legierungen) sollte die automatisierte Bestimmung (lineare Regression der logarithmierten wahren Spannung über die logarithmierte wahre plastische Dehnung, siehe 7.7) angewendet werden, um reproduzierbare Ergebnisse zu erhalten.
Matériaux métalliques - Tôles et bandes - Détermination du coefficient d'écrouissage en traction (ISO 10275:2007)
L'ISO 10275:2007 spécifie une méthode pour la détermination du coefficient d'écrouissage en traction des produits plats (tôles et bandes) en matériaux métalliques.
La méthode n'est valable que pour la partie de la courbe contrainte-déformation dans le domaine plastique où la courbe est continue et monotone.
Kovinski materiali - Pločevina in trakovi - Ugotavljanje koeficienta utrjanja (ISO 10275:2007)
Standard EN ISO 10275 določa metodo za ugotavljanje koeficienta utrjanja ploščatih izdelkov (pločevine in trakov), izdelanih iz kovinskih materialov. Postopek velja le za del krivulje stres-utrjanje v območju plastike, kjer je krivulja neprekinjena in enakomerna (glej 7.4). Pri materialih z nazobčanim krivuljo stresa-utrjanja v območju delovnega utrjanja (materiali, ki kažejo na Portevin-Le Chatelierjev učinek, npr. zlitine Al-Mg) naj bi za ponovljive rezultate uporabili samodejno določanje (linearna regresija logaritma pravega stresa v primerjavi z logaritmom plastične anizotropije, glej 7.7).

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 10275 was prepared by Technical Committee ISO/TC 164, Mechanical testing of metals, Subcommittee
SC 2, Ductility testing.
This second edition cancels and replaces the first edition (ISO 10275:1993), which has been technically

Introduction
In the former version of this International Standard, for the calculation of the true strain, the elastic strain did
not need to be subtracted from the total strain if it was lower than 10 % of the total strain.
In this new International Standard, the elastic strain is subtracted from the total strain for calculation of the true
strain, which is now referred to as “true plastic strain”.

Metallic materials — Sheet and strip — Determination of tensile
strain hardening exponent
1 Scope
This International Standard specifies a method for determining the tensile strain hardening exponent n of flat
products (sheet and strip) made of metallic materials.
The method is valid only for that part of the stress-strain curve in the plastic range where the curve is
continuous and monotonic (see 7.4).
In the case of materials with a serrated stress-strain curve in the work hardening range (materials which show
the Portevin-Le Chatelier effect, e.g. AlMg-alloys) the automatic determination (linear regression of the
logarithm true stress vs. the logarithm true plastic strain, see 7.7) should be used to give reproducible results.
