Plastics - Determination of tensile properties - Part 2: Test conditions for moulding and extrusion plastics (ISO 527-2:2025)
1.1 This document specifies the test conditions for determining the tensile properties of moulding and extrusion plastics, based upon the general principles given in ISO 527-1.
1.2 The methods are selectively suitable for use with the following range of materials in the preferred thickness, or, in case of specimen machined from moulded parts in the thickness as moulded:
— rigid and semi-rigid thermoplastics moulding, extrusion and cast materials, including compounds filled and reinforced by, for example, short fibres, small rods, plates or granules but excluding textile fibres (see ISO 527-4 and ISO 527-5).
NOTE See ISO 527-1:2019, Clause 3 for the definition of "rigid" and "semi-rigid".
— rigid and semi-rigid thermosetting moulding and cast materials, including filled and reinforced compounds but excluding textile fibres as reinforcement (see ISO 527-4 and ISO 527-5);
— thermotropic liquid crystal polymers.
The methods are not normally suitable for use with rigid cellular materials or sandwich structures containing cellular material. For rigid cellular materials, see ISO 1926.
The methods are not suitable for flexible films and sheets, of thickness smaller than 1 mm, see ISO 527-3.
1.3 The methods are applied using specimens which can be either moulded to the chosen dimensions or machined, cut or punched from injection‑ or compression‑moulded plates. The multipurpose test specimen is preferred (see ISO 20753).
Kunststoffe - Bestimmung der Zugeigenschaften - Teil2: Prüfbedingungen für Form-und Extrusionsmassen (ISO 527-2:2025)
Dieses Dokument legt auf der Basis der allgemeinen Grundsätze aus ISO 527 1 die Prüfbedingungen zur Bestimmung der Zugeigenschaften von Form- und Extrusionsmassen fest.
1.2 Die Verfahren sind speziell zur Anwendung für folgende Werkstoffgruppen in der bevorzugten Dicke oder bei aus Formteilen mechanisch herausgearbeiteten Probekörpern in der Dicke nach Ausformung geeignet:
steife und halbsteife thermoplastische Spritzguss-, Extrusions- und Gussformmassen einschließlich gefüllter und verstärkter Formmassen, beispielsweise mit Kurzfasern, kleinen Stäbchen, Plättchen oder Granulat, nicht jedoch mit Textilfasern (siehe ISO 527 4 und ISO 527 5).
ANMERKUNG Definition für „steif“ und „halbsteif“ siehe ISO 527 1:2019, Abschnitt 3;
steife und halbsteife härtbare Spritzguss- und Gussformmassen einschließlich gefüllter und verstärkter Formmassen, nicht jedoch mit Textilfasern als Verstärkungsmaterial (siehe ISO 527 4 und ISO 527 5);
thermotrope flüssigkristalline Polymere.
Die Verfahren sind üblicherweise nicht für Hartschäume oder Schichtstoff-Verbundwerkstoffe mit Schaumstoffkern geeignet. Für Hartschäume siehe ISO 1926.
Die Verfahren sind nicht geeignet für flexible Folien und Tafeln mit einer Dicke unter 1 mm, siehe ISO 527 3.
1.3 Die Verfahren werden an Probekörpern angewendet, die entweder in den ausgewählten Maßen geformt oder aus spritzgegossenen oder gepressten Platten ausgearbeitet, geschnitten oder gestanzt werden können. Der Vielzweckprobekörper wird bevorzugt (siehe ISO 20753).
Plastiques - Détermination des propriétés en traction - Partie 2: Conditions d'essai des plastiques pour moulage et extrusion (ISO 527-2:2025)
1.1 Le présent document spécifie les conditions d’essai pour la détermination des propriétés en traction des plastiques destinés au moulage et à l’extrusion, basées sur les principes généraux établis dans l’ISO 527-1.
1.2 Les méthodes conviennent sélectivement à la gamme des matériaux suivants, à l’épaisseur recommandée, ou, dans le cas d’une éprouvette usinée à partir de parties moulées, à l’épaisseur de moulage:
— matières thermoplastiques rigides et semi-rigides pour moulage, extrusion et coulée, y compris des compositions chargées et renforcées, par exemple de fibres courtes, de fins joncs, de plaques ou granulés mais excluant les fibres textiles (voir l’ISO 527-4 et l’ISO 527-5).
NOTE Se référer à l’ISO 527-1:2019, Article 3, pour la définition de «rigide» et «semi-rigide».
— matières thermodurcissables rigides et semi-rigides pour moulage et coulée, y compris les compositions chargées et renforcées mais excluant les fibres textiles comme renforcement (voir l’ISO 527-4 et l’ISO 527-5);
— polymères à cristaux liquides thermotropes.
En principe, les méthodes ne peuvent pas être appliquées aux matériaux alvéolaires rigides ou aux structures sandwichs contenant des matériaux alvéolaires. En ce qui concerne les matériaux alvéolaires rigides, voir l’ISO 1926.
Les méthodes ne conviennent pas pour des films et feuilles souples d’une épaisseur inférieure à 1 mm; voir l’ISO 527-3.
1.3 Les méthodes sont applicables aux éprouvettes qui sont soit moulées aux dimensions choisies, soit usinées, découpées ou poinçonnées à partir de plaques moulées par injection ou par compression. L’éprouvette à usages multiples est recommandée (voir l’ISO 20753).

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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 2, Mechanical
behavior, in collaboration with the European Committee for Standardization (CEN) Technical Committee
CEN/TC 249, Plastics, in accordance with the Agreement on technical cooperation between ISO and CEN
(Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 527-2:2012), which has been technically
revised.
The main changes are as follows:
— Figure 1 and Table 1 have been moved from Clause 11 to subclause 6.1;
— former subclause 6.6, Number of test specimens, has been renumbered as Clause 7 to align with
ISO 527-1:2019;
— the reference to ISO 3167 has been replaced with ISO 20753;
— test specimens 1A and 1B have been replaced by test specimen A1 and A2 according to ISO 20753;
— small test specimen in Annex A, Type 1BA and 1BB have been replaced by reduced scale specimen, as
specified in ISO 20753.
