Plastics - Determination of tensile properties - Part 1: General principles (ISO 527-1:2012)

ISO 527-1:2012 specifies the general principles for determining the tensile properties of plastics and plastic composites under defined conditions. Several different types of test specimen are defined to suit different types of material which are detailed in subsequent parts of ISO 527.
The methods are used to investigate the tensile behaviour of the test specimens and for determining the tensile strength, tensile modulus and other aspects of the tensile stress/strain relationship under the conditions defined.
The methods are not normally suitable for use with rigid cellular materials, for which ISO 1926 is used, or for sandwich structures containing cellular materials.

Kunststoffe - Bestimmung der Zugeigenschaften - Teil 1: Allgemeine Grundsätze (ISO 527-1:2012)

1.1   Dieser Teil von ISO 527 legt die allgemeinen Grundsätze zur Bestimmung der Zugeigenschaften von Kunststoffen und Kunststoff-Verbunden unter festgelegten Bedingungen fest. Mehrere verschiedene Probekörpertypen sind entsprechend den unterschiedlichen Werkstofftypen festgelegt, die in den folgenden Teilen von ISO 527 näher beschrieben werden.
1.2   Die Verfahren werden verwendet, um das Zugverformungsverhalten von Probekörpern zu untersuchen und die Zugfestigkeit, den Zugmodul und andere Gesichtspunkte der Zugspannungs-/Dehnungs-Beziehung unter festgelegten Bedingungen zu ermitteln.
1.3   Die Verfahren sind speziell zur Anwendung bei folgenden Werkstoffgruppen geeignet:
-   steife und halbsteife thermoplastische (siehe 3.12 und 3.13) Spritzguss-, Extrusions- und Gussform-massen einschließlich gefüllter und verstärkter Formmassen als Ergänzung zu ungefüllten Sorten; steife und halbsteife thermoplastische Platten und Folien;
-   steife und halbsteife duroplastische Formmassen einschließlich gefüllter und verstärkter Formmassen; steife und halbsteife duroplastische Platten einschließlich Schichtstoffe;
-   faserverstärkte duroplastische oder thermoplastische Verbundwerkstoffe mit unidirektionaler oder nichtunidirektionaler Verstärkung, wie Matten, Vliese und Gelege, Gewebe, Rovinggewebe, Kombinations- und Mischverstärkung, Stränge (Rovings) und Kurzfasern; Tafeln aus vorgetränkten Werkstoffen (Prepregs);
-   thermotrope flüssigkristalline Kunststoffe.
Die Verfahren sind üblicherweise nicht zur Anwendung mit harten Schaumstoffen, für die ISO 1926 angewendet wird, oder für Schichtstoff-Verbundwerkstoffen mit Schaumstoffkern geeignet.

Plastiques - Détermination des propriétés en traction - Partie 1: Principes généraux (ISO 527-1:2012)

L'ISO 527-1:2012 spécifie les principes généraux pour la détermination des propriétés en traction des plastiques et des composites en plastique dans des conditions définies. Plusieurs types différents d'éprouvettes sont définis en fonction des différents types de matériaux qui sont énumérés dans les parties suivantes de I'ISO 527.
Les méthodes sont utilisées pour étudier le comportement en traction des éprouvettes par la détermination de la résistance en traction, du module d'élasticité en traction et d'autres aspects de la relation contrainte/déformation en traction dans des conditions définies.
En principe, les méthodes ne peuvent pas être appliquées aux matériaux alvéolaires rigides, pour lesquels l'ISO 1926 est utilisée, ou aux structures sandwichs contenant des matériaux alvéolaires.

Polimerni materiali - Ugotavljanje nateznih lastnosti - 1. del: Splošna načela (ISO 527-1:2012)

Ta del standarda ISO 527 določa splošna načela za ugotavljanje nateznih lastnosti polimernih materialov in polimernih kompozitov pri določenih pogojih. Opredeljenih je več vrst preskušancev, da se zajamejo različne vrste materialov, ki so podrobno opisane v poznejših delih standarda ISO 527. Uporabljene so metode za preučevanje nateznih lastnosti preskušancev ter za ugotavljanje natezne trdnosti, nateznega modula in drugih vidikov razmerja natezna napetost/deformacija pri določenih pogojih. Metode so selektivno ustrezne za naslednje materiale: – trdi in poltrdi (glejte 3.12 in 3.13) plastomerni materiali za oblikovanje, ekstrudiranje in vlivanje, vključno s polnjenimi in ojačanimi spojinami poleg nepolnjenih vrst; trdi in poltrdi plastomerni trakovi in filmi; – trdi in poltrdi termoreaktivni materiali za oblikovanje, vključno s polnjenimi in ojačanimi spojinami; trdi in poltrdi termoreaktivni trakovi, vključno z laminati; – z vlakni ojačani termoreaktivni in plastomerni kompoziti, ki vsebujejo enosmerne ali večsmerne ojačitve, kot so mati, tkanine, tkani rovingi, rezane niti, kombinacijske in hibridne ojačitve, rovingi in brušena vlakna; trakovi iz predhodno impregniranih materialov; – termotropni polimeri iz tekočih kristalov. Metode običajno niso primerne za trde penjene materiale, za katere se uporablja standard ISO 1926, ali za strukture tipa »sendvič«, ki vsebujejo penjene materiale.

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 527-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 2, Mechanical properties.
This second edition cancels and replaces the first edition (ISO 527-1:1993), which has been technically revised.
It incorporates ISO 527-1:1993/Cor 1:1994 and ISO 527-1:1993/Amd 1:2005. The main changes are as follows.
— A method for the determination of Poisson’s ratio has been introduced. It is similar to the one used
in ASTM D638, but in order to overcome difficulties with precision of the determination of the lateral
contraction at small values of the longitudinal strain, the strain interval is extended far beyond the strain
region for the modulus determination.
— Definitions and methods have been optimized for computer controlled tensile test machines.
— The preferred gauge length for use on the multipurpose test specimen has been increased from 50 mm to
75 mm. This is used especially in ISO 527-2.
— Nominal strain and especially nominal strain at break will be determined relative to the gripping distance.
Nominal strain in general will be calculated as crosshead displacement from the beginning of the test,
relative to the gripping distance, or as the preferred method if multipurpose test specimens are used,
where strains up to the yield point are determined using an extensometer, as the sum of yield strain and
nominal strain increment after the yield point, the latter also relative to the gripping distanc
