Plastics - Determination of tensile properties - Part 1: General principles (ISO 527-1:2019)
1.1 This document 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.
1.2 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.
1.3 The methods are selectively suitable for use with the following materials:
— rigid and semi-rigid moulding, extrusion and cast thermoplastic materials, including filled and reinforced compounds in addition to unfilled types; rigid and semi-rigid thermoplastics sheets and films;
— rigid and semi-rigid thermosetting moulding materials, including filled and reinforced compounds; rigid and semi-rigid thermosetting sheets, including laminates;
— fibre-reinforced thermosets and thermoplastic composites incorporating unidirectional or non-unidirectional reinforcements, such as mat, woven fabrics, woven rovings, chopped strands, combination and hybrid reinforcement, rovings and milled fibres; sheet made from pre-impregnated materials (prepregs);
— thermotropic liquid crystal polymers.
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 527-1:2019)
1.1 Dieses Dokument legt die allgemeinen Grundsätze zur Bestimmung der Zugeigenschaften von Kunst-stoffen und Kunststoff-Verbundwerkstoffen unter festgelegten Bedingungen fest. Mehrere verschiedene Probekörpertypen sind für unterschiedliche Werkstoffarten festgelegt, die in den folgenden Teilen von ISO 527 näher beschrieben werden.
1.2 Die Verfahren werden verwendet, um das Zugverformungsverhalten von Probekörpern zu untersu-chen und die Zugfestigkeit, den Zugmodul und andere Gesichtspunkte der Zugspannungs-/Dehnungs-Bezie-hung unter festgelegten Bedingungen zu ermitteln.
1.3 Die Verfahren sind speziell zur Anwendung bei folgenden Werkstoffgruppen geeignet:
- steife und halbsteife thermoplastische Spritzguss-, Extrusions- und Gussformmassen, einschließlich gefüllter und verstärkter Verbunde als Ergänzung zu ungefüllten Sorten; steife und halbsteife thermo-plastische Platten und Folien;
- steife und halbsteife duroplastische Formmassen, einschließlich gefüllter und verstärkter Verbunde; steife und halbsteife duroplastische Platten einschließlich Schichtstoffe;
- faserverstärkte duroplastische und thermoplastische Verbundwerkstoffe mit unidirektionaler oder nichtunidirektionaler Verstärkung, wie Matten, Vliese und Gelege, Gewebe, Rovinggewebe, Kombina-tions- und Mischverstärkung, Stränge (Rovings) und Kurzfasern; Tafeln aus vorgetränkten Werkstoffen (Prepregs);
- thermotrope flüssigkristalline Polymere.
Die Verfahren sind üblicherweise nicht zur Anwendung mit harten Schaumstoffen, für die ISO 1926 ange-wendet wird, oder für Schichtstoff-Verbundwerkstoffe mit Schaumstoffkern geeignet.
Plastiques - Détermination des propriétés en traction - Partie 1: Principes généraux (ISO 527-1:2019)
1.1 Le présent document 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.
1.2 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.
1.3 Les méthodes conviennent sélectivement aux matériaux suivants:
— matières thermoplastiques rigides et semi-rigides pour moulage, extrusion et coulée, y compris les compositions chargées et renforcées en plus des types non chargés; feuilles et films en thermoplastiques rigides et semi-rigides;
— matières thermodurcissables rigides et semi-rigides pour moulage, y compris les compositions chargées et renforcées; feuilles thermodurcissables rigides et semi-rigides, y compris les stratifiés;
— composites thermoplastiques et thermodurcissables renforcés de fibres comportant des renforts unidirectionnels et multidirectionnels tels que mats, tissus, tissus stratifils, fils coupés, combinaisons de renforcements et hybrides, stratifils et fibres broyées; feuilles réalisées à partir de matières préimprégnées (préimprégnés);
— polymères à cristaux liquides thermotropes.
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 527-1:2019)
Ta dokument 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 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.
