Plastics - Determination of Charpy impact properties - Part 1: Non-instrumented impact test (ISO 179-1:2010)
ISO 179-1:2010 specifies a method for determining the Charpy impact strength of plastics under defined conditions. A number of different types of specimen and test configurations are defined. Different test parameters are specified according to the type of material, the type of test specimen and the type of notch.
The method can be used to investigate the behaviour of specified types of specimen under the impact conditions defined and for estimating the brittleness or toughness of specimens within the limitations inherent in the test conditions. It can also be used for the determination of comparative data from similar types of material.
The method has a greater range of applicability than that given in ISO 180 (Izod impact testing) and is more suitable for the testing of materials showing interlaminar shear fracture or of materials exhibiting surface effects due to environmental factors.
The method is suitable for use with the following range of materials:
rigid thermoplastic moulding and extrusion materials (including filled and reinforced compounds in addition to unfilled types) and rigid thermoplastics sheets;
rigid thermosetting moulding materials (including filled and reinforced compounds) and rigid thermosetting sheets (including laminates);
fibre-reinforced thermosetting and thermoplastic composites incorporating unidirectional or multi-directional reinforcements (such as mats, woven fabrics, woven rovings, chopped strands, combination and hybrid reinforcements, rovings and milled fibres) or incorporating sheets made from pre-impregnated materials (prepregs), including filled compounds;
thermotropic liquid-crystal polymers.
Kunstststoffe - Bestimmung der Charpy-Schlageigenschaften - Teil 1: Nicht instrumentierte Schlagzähigkeitsprüfung (ISO 179-1:2010)
Dieser Teil von ISO 179 legt ein Verfahren für die Bestimmung der Charpy-Schlagzähigkeit von Kunststoffen
unter festgelegten Bedingungen fest. Eine Anzahl von unterschiedlichen Probekörpertypen und Prüfanordnungen
wird festgelegt. Unterschiedliche Prüfbedingungen werden entsprechend dem Werkstofftyp,
dem Probekörpertyp und der Kerbart festgelegt.
1.2 Das Prüfverfahren kann angewendet werden, um das Verhalten festgelegter Probekörpertypen bei den
festgelegten Schlagbedingungen zu untersuchen und die Sprödigkeit oder Zähigkeit von Probekörpern innerhalb
der Grenzen der Prüfbedingungen zu beurteilen. Es kann ebenfalls für die Bestimmung von Vergleichsdaten
von ähnlichen Werkstofftypen angewendet werden.
1.3 Das Verfahren hat einen breiteren Anwendungsbereich als das in ISO 180 [1] angegebene und ist
besser geeignet zur Prüfung von Werkstoffen, die interlaminare Scherbrüche zeigen, oder von Werkstoffen,
die Oberflächeneffekte aufgrund von Umgebungseinflüssen aufweisen.
1.4 Das Prüfverfahren ist zur Anwendung auf folgende Werkstoffgruppen geeignet:
steife thermoplastische Spritzguss- und Extrusionsformmassen (einschließlich gefüllter und verstärkter
Verbundwerkstoffe zusätzlich zu ungefüllten Typen) sowie Platten aus steifen Thermoplasten;
steife wärmehärtbare Formmassen (einschließlich gefüllter und verstärkter Verbundwerkstoffe) und
Platten aus steifen Duroplasten (einschließlich solcher aus Schichtstoffen);
faserverstärkte duroplastische und thermoplastische Verbundwerkstoffe mit unidirektionaler oder multidirektionaler
Verstärkung (wie Matten, Gewebe, Rovinggewebe, Kurzfasern, verbundene und Hybridverstärkungen,
Rovings und gemahlene Fasern) oder Verbundplatten aus vorimprägnierten Werkstoffen
(Prepregs), einschließlich gefüllter und verstärkter Verbundwerkstoffe;
thermotrope flüssigkristalline Polymere.
Plastiques - Détermination des caractéristiques au choc Charpy - Partie 1: Essai de choc non instrumenté (ISO 179-1:2010)
L'ISO 179-1:2010 spécifie une méthode de détermination de la résistance au choc Charpy des plastiques dans des conditions définies. De nombreux types différents d'éprouvettes et de configurations d'essai sont définis. Divers paramètres d'essai sont spécifiés selon le type de matériau, le type d'éprouvette et le type d'entaille.
La méthode peut être utilisée pour l'étude du comportement d'éprouvettes définies soumises à des conditions de choc déterminées et pour l'estimation de la fragilité ou de la ténacité des éprouvettes dans les limites inhérentes aux conditions d'essai. Elle peut également être utilisée pour déterminer des résultats comparatifs propres à des types similaires de matériaux.
Le domaine d'application de la méthode est plus étendu que celui de l'ISO 180 (essai de choc Izod) et il convient mieux à l'essai des matériaux qui présentent des défaillances de type cisaillement interlaminaire ou de ceux qui présentent des effets de surface dus à des facteurs d'environnement.
La méthode est applicable à la gamme des matériaux suivants:
matières thermoplastiques rigides pour moulage et extrusion (y compris les compositions chargées et renforcées en plus des types non chargés) et feuilles thermoplastiques rigides;
matières thermodurcissables rigides pour moulage (y compris les compositions chargées et renforcées) et feuilles thermodurcissables rigides (y compris les stratifiés);
composites thermoplastiques et thermodurcissables renforcés par des fibres comportant des renforts unidirectionnels ou multidirectionnels (tels que mats, tissus, tissus stratifils, fils de base coupés, combinaison de renforcements et hybrides, stratifils et fibres broyées) ou comportant des feuilles réalisées à partir de matières préimprégnées (prepregs), y compris les compositions chargées et renforcées;
polymères de cristaux liquides thermotropes.
Polimerni materiali - Ugotavljanje udarne žilavosti pa Charpyju - 1. del: Preskus udarne žilavosti z neinstrumentalno metodo (ISO 179-1:2010)
1.1 Ta del ISO 179 določa metodo za ugotavljanje udarne žilavosti polimernih materialov po Charpyju pod opredeljenimi pogoji. Opredeljene so številne različne vrste vzorcev in konfiguracij preskusa. Glede na vrsto materiala, vrsto vzorca in vrsto zareze so opredeljeni različni preskusni parametri.
1.2 Metoda se lahko uporablja za preiskovanje obnašanja določene vrste vzorca pod opredeljenimi udarnimi pogoji in za ocenjevanje krhkosti ali žilavosti vzorcev znotraj omejitev, ki veljajo v preskusnih pogojih. Lahko se uporablja tudi za ugotavljanje primerjalnih podatkov podobnih vrst materiala.
1.3 Metoda ima večji razpon uporabnosti kot metoda, navedena v ISO 180[1], in je primernejša za preskušanje materialov, na katerih se kaže medlaminarni strižni lom, ali materialov, na katerih se kažejo površinski učinki dejavnikov okolja
1.4 Metoda je primerna za uporabo pri naslednjih materialih:
- trdni plastomerni materiali za brizganje ali iztiskanje (vključno s polnjenimi in ojačanimi spojinami, poleg nepolnjenih vrst) in trdni plastomerni trakovi;
- trdni termoreaktivni materiali za brizganje (vključno s polnjenimi in ojačanimi spojinami) in trdni 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) ali vsebujejo trakove iz predhodno impregniranih materialov, vključno s polnjenimi in ojačanimi spojinami;
- termotropni polimeri iz tekočih kristalov.
1.5 Zarezani vzorci običajno niso primerni za uporabo s trdnimi penjenimi materiali, kompoziti, ojačanimi z dolgimi vlakni, ali termotropnimi polimeri iz tekočih kristalov. V teh primerih se lahko uporabijo nezarezani vzorci.
1.6 Metoda je primerna za uporabo pri vzorcih, oblikovanih glede na izbrane mere, strojno obdelanih iz osrednjega dela standardnega večnamenskega preskusnega vzorca (glej ISO 3167) ali strojno obdelanih iz končnih proizvodov ali polizdelkov, kot so odlitki, laminati ali iztisnjeni ali uliti trakovi.
1.7 Metoda določa prednostne mere za preskusne vzorce. Rezultati preskusov, ki se izvajajo na vzorcih različnih mer ali z različnimi zarezami ali na vzorcih, ki so pripravljeni pod drugačnimi pogoji, morda ne bodo primerljivi. Na rezultate lahko vplivajo tudi drugi dejavniki, kot so energetska zmogljivost aparata, udarna hitrost in priprava vzorca. Kadar so potrebni primerjalni podatki, je zato treba te dejavnike skrbno nadzorovati in beležiti.
1.8 Metoda se ne sme uporabljati kot vir podatkov za izračun zasnove. Informacije o značilnem obnašanju materiala se lahko pridobijo s preskušanjem pri različnih temperaturah, s spreminjanjem polmera zareze in/ali debeline vzorca ter s preskušanjem vzorcev, pripravljenih pod različnimi pogoji.

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 179-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 2, Mechanical
properties.
This second edition cancels and replaces the first edition (ISO 179-1:2000), which has been technically
revised. The main changes are as follows:
⎯ a new subclause (6.5) has been added, defining the span between the specimen supports and indicating
a convenient position at which it can be measured;
⎯ a new annex, Annex C, has been added, giving a method of measuring the radius of the notch in a
notched specimen.
This second edition also incorporates the Amendment ISO 179-1:2000/Amd.1:2005.
ISO 179 consists of the following parts, under the general title Plastics — Determination of Charpy impact
properties:
⎯ Part 1: Non-instrumented impact test
⎯ Part 2: Instrumented impact test
