Metallic materials - Uniaxial creep testing in tension - Method of test (ISO 204:2009)
ISO 204:2009 specifies the method for the uninterrupted and interrupted creep tests and defines the properties of metallic materials which can be determined from these tests, in particular the creep elongation and the time of creep rupture, at a specified temperature.
The stress rupture test is also covered, as is the testing of notched test pieces.
Metallische Werkstoffe - Einachsiger Zeitstandversuch unter Zugbeanspruchung - Prüfverfahren (ISO 204:2009)
Diese Internationale Norm legt das Prüfverfahren für den nicht unterbrochenen und den unterbrochenen
Zeitstandversuch fest und spezifiziert die Eigenschaften metallischer Werkstoffe, die mit diesen Versuchen
bestimmt werden können, besonders die Kriechdehnung und die Bruchzeit bei einer vorgeschriebenen Temperatur.
Der Zeitstandversuch wird von dieser Internationalen Norm ebenso behandelt wie die Prüfung von gekerbten
Proben.
ANMERKUNG Beim Zeitstandversuch wird während der Prüfung üblicherweise nicht die Dehnung aufgezeichnet, sondern
nur die Zeit bis zum Bruch unter einer gegebenen Last oder bis festgestellt wird, dass eine vorgeschriebene Zeit
unter einer gegebenen Last überschritten wurde.
Matériaux métalliques - Essai de fluage uniaxial en traction - Méthode d'essai (ISO 204:2009)
L'ISO 204:2009 spécifie la méthode pour les essais de fluage ininterrompu et interrompu et définit les caractéristiques des matériaux métalliques qui peuvent être déterminées à partir de ces essais, en particulier l'allongement de fluage et le temps de rupture par fluage, à une température spécifiée.
L'essai de rupture sous contrainte est également couvert, de même que les essais sur éprouvettes entaillées.
Kovinski materiali - Preskušanje nesoosnega lezenja pri nategu - Metoda preskušanja (ISO 204:2009)
Ta mednarodni standard določa metodo preskušanja neprekinjenega in prekinjenega lezenje ter opredeljuje značilnosti kovinskih materialov, ki se lahko določijo s temi preskusi, zlasti raztezek lezenja in čas lezenja do loma pri določeni temperaturi. Preskus obremenitve do loma in preskušanje zarezanega preskušanca sta prav tako zajeta v tem mednarodnem standardu.

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 204 was prepared by Technical Committee ISO/TC 164, Mechanical testing of metals, Subcommittee
SC 1, Uniaxial testing.
This second edition cancels and replaces the first edition (ISO 204:1997), which has been technically revised.

Introduction
This International Standard is an extensive revision of the first edition of ISO 204:1997 and incorporates many
recommendations developed through the European Creep Collaborative Committee (ECCC).
New annexes have been added concerning temperature measurement using thermocouples and their
calibration, creep testing test pieces with circumferential Vee and blunt (Bridgman) notches, estimation of
measurement uncertainty and methods of extrapolation of creep rupture life.
NOTE Information is sought relating to the influence of off-axis loading or bending on the creep properties of various
materials. Consideration will be given at the next revision of this International Standard as to whether the maximum
amount of bending should be specified and an appropriate calibration procedure be recommended. The decision will need
[39]
to be based on the availability of quantitative data .
INTERNATIONAL STANDARD ISO 204:2009(E)
Metallic materials — Uniaxial creep testing in tension — Method
of test
1 Scope
This International Standard specifies the method for the uninterrupted and interrupted creep tests and defines
the properties of metallic materials which can be determined from these tests, in particular the creep
elongation and the time of creep rupture, at a specified temperature.
The stress rupture test is also covered by this International Standard, as is the testing of notched test pieces.
NOTE In stress rupture testing, elongation is not generally recorded during the test, only the time to failure under a
given load, or to note that a predetermined time was exceeded under a given force.

The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
NOTE Several different gauge lengths and reference lengths are specified in this International Standard. These
lengths reflect custom and practice used in different laboratories throughout the world. In some cases, the lengths are
physically marked on the test piece as lines or ridges; in other cases, the length may be a virtual length based upon
calculations to determine an appropriate length to be used for the determination of creep elongation. For some test pieces,
L , L and L are the same length (see 3.1, 3.2 and 3.5).
