Plastics - Determination of puncture impact behaviour of rigid plastics - Part 1: Non-instrumented impact testing (ISO 6603-1:2000)

This International Standard specifies methods for the determination of puncture-impact properties of rigid plastics in
the form of flat test specimens, such as discs or square pieces, under defined conditions. Specimens may be
moulded directly, cut from sheets or taken from finished products. Different types of test specimens and test
conditions are defined.
These falling-dart methods are used to investigate the behaviour of plastic sheeting or mouldings under the impact
of a striker applied perpendicular to the plane of the specimen.
This part of ISO 6603 can be used if it is sufficient to characterize the impact behaviour of plastics by a threshold
value of impact-failure energy based on many test specimens. ISO 6603-2 is used if a force-deflection or force-time
diagram, recorded at nominally constant striker velocity, is necessary for detailed characterization of the impact
behaviour.
These test methods are applicable to specimens with a thickness between 1 mm and 4 mm.
NOTE For thicknesses less than 1 mm, ISO 7765 should preferably be used. Thicknesses greater than 4 mm may be
tested if the equipment is suitable, but the test falls outside the scope of ISO 6603-1 and ISO 6603-2.
These methods are suitable for use with the following types of material:
_ rigid thermoplastic moulding and extrusion materials, including filled, unfilled and reinforced compounds and
sheets;
_ rigid thermosetting moulding and extrusion materials, including filled and reinforced compounds, sheets and
laminates;
_ fibre-reinforced thermoset and thermoplastic composites incorporating unidirectional or non-unidirectional
reinforcements such as mats, woven fabrics, woven rovings, chopped strands, combination and hybrid
reinforcements, rovings, milled fibres and sheets made from pre-impregnated materials (prepregs).
These methods are also applicable to specimens which are either moulded or machined from finished products,
laminates and extruded or cast sheet.
The test results are comparable only if the conditions of preparation of the specimens, their dimensions and
surfaces as well as the test conditions are the same. In particular, results determined on specimens of different
thickness cannot be compared with one another (see annex E of ISO 6603-2:—). Comprehensive evaluation of the
reaction to impact stress requires that determinations be made as a function of impact velocity and temperature for
different material variables, such as crystallinity and moisture content.
The impact behaviour of finished products cannot be predicted directly from this test, but specimens may be taken
from finished products (see above) for test by these methods.
Test data developed by these methods should not be used for design calculations. However, information on the
typical behaviour of the material can be obtained by testing at different temperatures and impact velocities (see
annex D of ISO 6603-2:—), by varying the thickness (see annex E of ISO 6603-2:—) and by testing specimens
prepared under different conditions.
Two statistical methods of test are described in this part of ISO 6603:
_ Method A: staircase method (individual) (preferred)
In this method, a uniform energy increment is employed during testing. The energy is decreased or increased
by the uniform increment after testing each specimen, depending upon the observed result (pass or fail) for the
preceding test.
_ Method B: group method (optional)
In this method, successive groups of at least ten test specimens are t

Kunststoffe - Bestimmung des Durchstoßverhaltens von festen Kunststoffen - Teil 1: Nicht-instrumentierter Schlagversuch (ISO 6603:2000)

Diese Internationale Norm beschreibt Verfahren zur Bestimmung des Durchstoßverhaltens von festen Kunststoffen in Form von flachen Probekörpern wie runden oder quadratischen Platten unter festgelegten Bedingungen. Die Probekörper dürfen direkt geformt, aus Tafeln herausgeschnitten oder Fertigprodukten entnommen werden. Es werden unterschiedliche Arten von Probekörpern und Prüfbedingungen festgelegt. Diese Fallbolzenversuche dienen zur Charakterisierung des Verhaltens von Kunststoffbahnen oder Formteilen, die durch den Aufprall eines Stoßkörpers rechtwinklig zur Ebene des Probekörpers beansprucht werden.

Plastiques - Détermination du comportement des plastiques rigides perforés sous l'effet d'un choc - Partie 1: Essais de choc non instrumentés (ISO 6603-1:2000)

La présente Norme internationale spécifie des méthodes de détermination du comportement au choc avec
perforation des plastiques rigides sous forme d'éprouvettes planes, telles que des disques ou des pièces carrées,
dans des conditions définies. Les éprouvettes peuvent être moulées directement, prélevées dans des plaques ou
des produits finis. Différents types d'éprouvettes et de conditions d'essai sont définis.
Ces méthodes d'essai par chute de projectile sont utilisées pour étudier le comportement d'objets moulés ou de
feuilles en matériaux plastiques soumis à une contrainte de choc appliquée à l'aide d'un percuteur
perpendiculairement au plan de l'éprouvette.
La présente partie de l'ISO 6603 peut être utilisée lorsqu'il est suffisant de caractériser le comportement au choc
des plastiques par une valeur seuil de l'énergie de rupture par choc à partir d'un grand nombre d'éprouvettes.
L'ISO 6603-2 est utilisée si une courbe force-flèche ou force-temps, enregistrée avec une vitesse du percuteur
nominalement constante, est nécessaire pour obtenir une caractérisation détaillée du comportement au choc.
Ces méthodes d'essai sont applicables aux éprouvettes d'épaisseur comprise entre 1 mm et 4 mm.
NOTE Dans le cas d'épaisseurs inférieures à 1 mm, il est préférable d'utiliser l'ISO 7765. Des épaisseurs de plus de 4 mm
peuvent être soumises à l'essai si l'appareillage est approprié mais, dans ce cas, l'essai ne relève pas du domaine d'application
de la présente partie de l'ISO 6603-1 et de l'ISO 6603-2.
Elles peuvent être utilisées avec les types suivants de matériaux:
_ thermoplastiques rigides pour moulage et extrusion, y compris les feuilles et les compositions chargées, non
chargées et renforcées;
_ plastiques thermodurcissables rigides pour moulage et extrusion, y compris les stratifiés, les feuilles et les
compositions chargées et renforcées;
_ composites thermodurcis et thermoplastiques renforcés de fibres, à renforts unidirectionnels ou non, tels que
les mats, tissus, tissus stratifiés, fils de base coupés, renforts complexes et hybrides, stratifiés, fibres broyées,
et feuilles préimprégnées.
Ces méthodes sont applicables aux éprouvettes qui peuvent être moulées ou usinées à partir de produits finis, de
stratifiés et de feuilles extrudées ou moulées.
Les résultats d'essai ne sont comparables que si les conditions de préparation des éprouvettes, les dimensions et
les surfaces de celles-ci, ainsi que les conditions d'essai sont les mêmes. Il n'est, en particulier, pas possible de
comparer des résultats obtenus sur des éprouvettes d'épaisseur différente (voir l'annexe E de l'ISO 6603-2:—).
Une évaluation exhaustive de la réaction au choc nécessite la réalisation de déterminations en fonction de la
vitesse d'impact et de la température pour différentes variables du matériau, telles que la structure cristalline ou la
teneur en humidité.
L'essai ne permet pas de prévoir directement le comportement au choc des produits finis mais ces méthodes
permettent de faire des essais sur des éprouvettes prélevées dans ces produits (voir ci-dessus).
Il n'est pas conseillé d'utiliser les données dérivées de la présente méthode à des fins de calcul. Des essais à
différentes températures et vitesses d'impact (voir l'annexe D de l'ISO 6603-2:—), à différentes épaisseurs (voir
l'annexe E de l'ISO 6603-2:—) et sur des éprouvettes préparées dans des conditions différentes permettent
néanmoins de recueillir des informations sur le comportement type des matériaux.

Foreword
lS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of preparing international
Standards is normally carried out through IS0 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, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council. They are approved in accordance with IS0 procedures requiring at
least 75 % approval by the member bodies voting.
International Standard IS0 6603/ 1 was prepared by Technical Committee lSO/TC 61,
