Plastics - Determination of tensile properties - Part 2: Test conditions for moulding and extrusion plastics (ISO 527-2:2012)

This part of ISO 527 specifies the test conditions for determining the tensile properties of moulding and extrusion plastics, based upon the general principles given in ISO 527-1. The methods are selectively suitable for use with the following range of materials: - 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 527-1:2012, 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; - 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. The methods are applied using specimens which may be either moulded to the chosen dimensions or machined, cut or punched from injection- or compression-moulded plates. The multipurpose test specimen is preferred.

Kunststoffe - Bestimmung der Zugeigenschaften - Teil 2: Prüfbedingungen für Form- und Extrusionsmassen (ISO 527-2:2012)

Bestimmung der Zugeigenschaften von Form- und Extrusionsmassen fest.
1.2 Die Verfahren sind speziell zur Anwendung für folgende Werkstoffgruppen 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). Definition für „steif“ und
-halbsteif- siehe ISO 527-1:2012, Abschnitt 3;
- steife und halbsteife duroplastische Spritzguss- und Gussformmassen einschließlich gefüllter und
verstärkter Formmassen, nicht jedoch mit Textilfasern als Verstärkungsmaterial (siehe ISO 527-4 und
ISO 527-5);
- thermotrope flüssigkristalline Kunststoffe.
Die Verfahren sind üblicherweise nicht für harte Schaumstoffe oder Schichtstoff-Verbundwerkstoffe mit
Schaumstoffkern geeignet. Für steife Schaumstoffe 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.
Der Vielzweckprobekörper wird bevorzugt verwendet (siehe ISO 20753).

Plastiques - Détermination des propriétés en traction - Partie 2: Conditions d'essai des plastiques pour moulage et extrusion (ISO 527-2:2012)

L'ISO 527-2:2012 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.

Polimerni materiali - Ugotavljanje nateznih lastnosti - 2. del: Preskusni pogoji za polimerne materiale za oblikovanje in ekstrudiranje (ISO 527-2:2012)

Ta del standarda ISO 527 določa preskusne pogoje za ugotavljanje nateznih lastnosti polimernih materialov za oblikovanje in ekstrudiranje na podlagi splošnih načel iz standarda ISO 527-1. Metode so selektivno ustrezne za naslednje vrste materialov: – trdi in poltrdi plastomerni materiali za oblikovanje, ekstrudiranje in vlivanje, vključno s spojinami, polnjenimi in ojačanimi z na primer kratkimi vlakni, majhnimi palicami, ploščami ali granulami, razen tekstilnih vlaken. Glej točko 3 standarda ISO 527-1:2012 za definicijo izrazov »trdi« in »poltrdi«. – trdi in poltrdi plastomerni materiali za oblikovanje in vlivanje, vključno s polnjenimi in ojačanimi spojinami, razen tekstilnih vlaken kot ojačitev; – termotropni polimeri iz tekočih kristalov. Metode običajno niso primerne za trde penjene materiale ali strukture tipa »sendvič«, ki vsebujejo penjeni material. Za trde penjene materiale glejte standard ISO 1926. Metode niso primerne za gibljive filme in trakove, ki so tanjši od 1 mm, glejte standard ISO 527-3. Metode se uporabljajo na preskušancih, ki so lahko oblikovani, da se dosežejo želene dimenzije, ali strojno obdelani, rezani ali iztisnjeni iz brizgalno vlitih in kompresijsko oblikovanih plošč. Priporoča se večnamenski preskušanec.

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 527-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 2, Mechanical properties.
This second edition cancels and replaces the first edition (ISO 527-2:1993), which has been technically revised.
ISO 527 consists of the following parts, under the general title Plastics — Determination of tensile properties:
— Part 1: General principles
— Part 2 :Test conditions for moulding and extrusion plastics
— Part 3: Test conditions for films and sheets

1.1 This part of ISO 527 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:
— 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). See ISO 527-1:2012, 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 may 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).

Plastics — Determination of tensile properties —
Part 2:
Test conditions for moulding and extrusion plastics
1 Scope
1.1 This part of ISO 527 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:
− rigid and semi rigid thermoplastics moulding, extrusion and cast materials, including compounds filled and
reinforced by e.g. short fibres, small rods, plates or granules but excluding textile fibres (see ISO 527-4
and ISO 527-5). See also ISO527-1 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. Testing conditions of sandwich structures shall be
agreed upon by experts.
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 usin
