Plastics - Determination of compressive properties (ISO 604:2002)

This International Standard specifies a method for determining the compressive properties of plastics under defined
conditions. A standard test specimen is defined but its length may be adjusted to prevent buckling under load from
affecting the results. A range of test speeds is included.
The method is used to investigate the compressive behaviour of the test specimens and for determining the
compressive strength, compressive modulus and other aspects of the compressive stress/strain relationship under
the conditions defined.
The method applies to the following range of materials:
 rigid and semi-rigid [1] thermoplastic moulding and extrusion materials, including compounds filled and
reinforced by e.g. short fibres, small rods, plates or granules in addition to unfilled types; rigid and semi-rigid
thermoplastic sheet;
 rigid and semi-rigid thermoset moulding materials, including filled and reinforced compounds; rigid and semirigid
thermoset sheet;
 thermotropic liquid-crystal polymers.
In agreement with ISO 10350-1 and ISO 10350-2, this International Standard applies to fibre-reinforced
compounds with fibre lengths u 7,5 mm prior to processing.
The method is not normally suitable for use with materials reinforced by textile fibres (see references [2] and [5]),
fibre-reinforced plastic composites and laminates (see [5]), rigid cellular materials (see [3]) or sandwich structures
containing cellular material or rubber (see [4]).
The method is performed using specimens which may be moulded to the chosen dimensions, machined from the
central portion of a standard multipurpose test specimen (see ISO 3167) or machined from finished or semifinished
products such as mouldings or extruded or cast sheet.
The method specifies preferred dimensions for the test specimen. Tests which are carried out on specimens of
different dimensions, or on specimens which are prepared under different conditions, may produce results which
are not comparable. Other factors, such as the test speed and the conditioning of the specimens, can also
influence the results. Consequently, when comparable data are required, these factors must be carefully controlled
and recorded.

Kunststoffe - Bestimmung von Druckeigenschaften (ISO 604:2002)

Diese Internationale Norm legt ein Verfahren zur Ermittlung der Druckeigenschaften von Kunststoffen unter definierten Bedingungen fest. Es ist ein genormter Probekörper festgelegt, jedoch kann seine Länge so abgestimmt werden, dass eine Beeinflussung der Ergebnisse durch ein Knicken unter Last vermieden wird. Eine Liste von Prüfgeschwindigkeiten ist mit aufgenommen.
Das Verfahren wird für die Untersuchung des Druckverhaltens der Probekörper und für die Bestimmung der Druckfestigkeit, des Druckmoduls und anderer Gesichtspunkte der Druckspannungs-Stauchungs-Beziehung unter den definierten Bedingungen verwendet.
Das Prüfverfahren ist zur Anwendung auf folgende Werkstoffgruppen geeignet:
¾ steife und halbsteife [1] thermoplastische Spritzguss- und Extrusionswerkstoffe, einschließlich gefüllter und verstärkter Formmassen als Ergänzung zu ungefüllten Typen, z. B. durch Kurzfasern, kleine Stäbchen, Plättchen oder Granulat verstärkte Formmassen; steife und halbsteife thermoplastische Tafeln;
¾ steife und halbsteife duroplastische Werkstoffe, einschließlich gefüllter und verstärkter Formmassen; steife und halbsteife duroplastische Tafeln;
¾ thermotrope flüssigkristalline Polymere.
In Übereinstimmung mit ISO 10350-1 und ISO 10350-2 gilt diese Internationale Norm für faserverstärkte Formmassen mit einer Faserlänge von £ 7,5 mm vor der Verarbeitung.
Das Verfahren ist üblicherweise nicht zur Anwendung bei textilfaserverstärkten Werkstoffen (siehe Verweisungen [2] und [5]), faserverstärkten Kunststoff-Verbundwerkstoffen und Laminaten (siehe [5]) sowie harten Schaumstoffen (siehe [3]) oder Schichtstoff-Verbundwerkstoffen mit Schaumstoffkern oder Gummi (siehe [4]) geeignet.
Das Verfahren ist für Probekörper geeignet, die direkt in den gewählten Maßen geformt werden, aus dem Mittelteil eines Norm-Vielzweckprobekörpers (siehe ISO 3167) ausgearbeitet werden oder aus fertigen oder halbfertigen Produkten wie Formteilen, extrudierten oder gegossenen Tafeln ausgearbeitet werden.

Plastiques - Détermination des propriétés en compression (ISO 604:2002)

La présente Norme internationale spécifie une méthode pour la détermination des propriétés en compression des
plastiques dans des conditions définies. Une éprouvette normalisée est décrite et sa longueur est ajustée afin
d'éviter un flambage sous charge pouvant affecter les résultats. Une gamme de vitesses d'essais est incluse.
La méthode est utilisée pour l'étude du comportement en compression des éprouvettes et pour la détermination de
la résistance à la compression, du module en compression et d'autres aspects des relations entre la contrainte et
la déformation en compression dans les conditions définies.
La méthode est applicable à la gammes de matériaux suivants:
 matériaux thermoplastiques rigides et semi-rigides [1] pour moulage et extrusion, y compris les compositions
chargées et renforcées, par exemple, de fibres courtes, fins bâtonnets, plaquettes et granulés, en plus des
types non chargés; feuilles thermoplastiques rigides et semi-rigides;
 matériaux thermodurcissables rigides et semi-rigides pour moulage, y compris les compositions chargées et
renforcées; feuilles thermodurcissables rigides et semi-rigides;
 polymères de cristaux liquides thermotropes.
En accord avec l'ISO 10350-1 et l'ISO 10350-2, cette Norme internationale s'applique aux compositions renforcées
avec des fibres dont les longueurs avant mise en oeuvre sont inférieures ou égales à 7,5 mm.
La méthode ne convient normalement pas à l'utilisation de matériaux renforcés par des fibres textiles (voir les
références [2] et [5]), de composites plastiques renforcés par des fibres et de stratifiés (voir [5]), de matériaux
alvéolaires rigides (voir [3]), de structures sandwiches contenant des matériaux alvéolaires et de caoutchouc
(voir [4]).
La méthode est appliquée en utilisant des éprouvettes qui sont soit moulées aux dimensions choisies, soit usinées
à partir de la partie centrale de l'éprouvette à usages multiples normalisée (voir ISO 3167) ou usinées à partir de
produits finis et semi-finis, tels que pièces moulées ou feuilles extrudées ou coulées.
La méthode spécifie les dimensions recommandées pour les éprouvettes. Des essais réalisés avec des
éprouvettes de dimensions différentes, ou préparées dans des conditions différentes, peuvent donner des résultats
qui ne sont pas comparables. D'autres facteurs, tels que la vitesse d'essai et le conditionnement des éprouvettes
peuvent également avoir une répercussion sur les résultats. En conséquence, lorsque des résultats comparables
sont nécessaires, ces facteurs doivent être soigneusement contrôlés et enregistrés.

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 3. 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 International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 604 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 2, Mechanical properties. This third edition cancels and replaces the second edition (ISO 604:1993), which has been technically revised.  a method of correcting for curvature at the beginning of the stress/strain curve is given (see 10.2.2);  a method of correcting for the compliance of the test machine is given (see annex C). Annexes A and C form a normative part of this International Standard. Annex B is for information only.
