Plastics - Determination of Charpy impact properties - Part 1: Non-instrumented impact test (ISO 179-1:2023)
This document 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.
Kunststoffe - Bestimmung der Charpy-Schlageigenschaften - Teil 1: Nicht instrumentierte Schlagzähigkeitsprüfung (ISO 179-1:2023)
Dieses Dokument 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.
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.
Plastiques - Détermination des caractéristiques au choc Charpy - Partie 1: Essai de choc non instrumenté (ISO 179-1:2023)
Le présent document spécifie une méthode de détermination de la résistance au choc Charpy des plastiques dans des conditions définies. De nombreux types d’éprouvettes et de configurations d’essai différents sont définis. Divers paramètres d’essai sont spécifiés selon le type de matière, le type d’éprouvette et le type d’entaille.
La présente méthode peut être utilisée pour l’étude du comportement des types d’éprouvettes spécifiés soumises à des conditions de choc définies 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.
Polimerni materiali - Ugotavljanje udarne žilavosti pa Charpyju - 1. del: Preskus udarne žilavosti z neinstrumentalno metodo (ISO 179-1:2023)
Standard ISO 179-1:2010 določa metodo za ugotavljanje udarne žilavosti polimernih materialov po Charpyju pod določenimi pogoji. Določenih je več različnih vrst vzorcev in preskusnih konfiguracij. Različni preskusni parametri so določeni glede na vrsto materiala, vrsto preskusnega vzorca in vrsto zareze.
Metodo je mogoče uporabiti za preiskovanje vedenja določenih vrst vzorcev pod določenimi udarnimi pogoji in ocenjevanje krhkosti ali žilavosti vzorcev v okviru omejitev preskusnih pogojev. Uporabiti jo je mogoče tudi za ugotavljanje primerljivih podatkov za podobne vrste materiala.
Metoda ima širši razpon uporabnosti kot metoda, navedena v standardu ISO 180 (preskušanje udarne žilavosti po Izodu), in je primernejša za preskušanje materialov, na katerih se kaže medlaminarni strižni lom, ali materialov, na katerih se kažejo površinski učinki dejavnikov okolja.
Metoda je ustrezna za naslednje vrste materialov:
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.
