Plastics - Determination of resistance to environmental stress cracking (ESC) - Part 2: Constant tensile load method (ISO 22088-2:2006)

This part of ISO 22088 specifies methods for the determination of environmental stress cracking (ESC) of thermoplastics when they are subjected to a constant tensile load in the presence of chemical agents. It is applicable to test specimens prepared by moulding and/or machining and can be used both for the assessment of ESC of plastic materials exposed to different environments, and for the determination of ESC of different plastic materials exposed to a specific environment. This is essentially a ranking test and is not intended to provide data to be used for design or performance prediction.

Kunststoffe - Bestimmung der Beständigkeit gegen umgebungsbedingte Spannungsrissbildung (ESC) - Teil 2: Zeitstandzugversuch (ISO 22088-2:2006)

Dieser Teil von ISO 22088 legt Verfahren zur Bestimmung der umgebungsbedingten Spannungsrissbildung (ESC) von thermoplastischen Kunststoffen fest, während diese in Gegenwart von chemisch wirksamen Medien einer konstanten Zugbelastung ausgesetzt sind.
Die Norm ist auf durch Formgebung und/oder mechanisches Bearbeiten hergestellte Probekörper anwendbar, und sie kann sowohl für die Beurteilung der ESC von Kunststoffmaterialien, die unterschiedlichen Medien ausgesetzt sind als auch für die Bestimmung der ESC von verschiedenen Kunststoffmaterialien, die einem bestimmten Medium ausgesetzt sind, angewendet werden.
Bei dem Verfahren handelt es sich im Wesentlichen um eine Rangordnungsprüfung, und es ist nicht zur Lieferung von Daten vorgesehen, die für konstruktive Zwecke oder zur Vorhersage der Gebrauchstauglichkeit zu verwenden sind.
ANMERKUNG   Verfahren zur Bestimmung der umgebungsbedingten Spannungsrissbildung mit einer Prüfung mit konstanter Dehnung sind in ISO 22088-3, ISO 22088-4 und ISO 22088-5 festgelegt.

Plastiques - Détermination de la fissuration sous contrainte dans un environnement donné (ESC) - Partie 2: Méthode sous contrainte de traction constante (ISO 22088-2:2006)

L'ISO 22088-2:2006 spécifie des méthodes pour la détermination de la fissuration sous contrainte dans un environnement donné (ESC) des thermoplastiques soumis à une force de traction constante en présence d'agents chimiques.
L'essai est applicable aux éprouvettes d'essai préparées par moulage et/ou usinage, et peut être utilisé à la fois pour l'évaluation de l'ESC de matières plastiques exposées à différents environnements, et pour la détermination de l'ESC de différentes matières plastiques exposées à un environnement spécifique.
Il s'agit ici essentiellement d'un essai de classement qui n'est pas destiné à fournir des données exploitables pour la conception ou des prévisions de performance.
Des méthodes pour la détermination de la fissuration sous contrainte dans un environnement donné à l'aide d'un essai à déformation constante sont spécifiées dans l'ISO 22088-3, l'ISO 22088-4 et l'ISO 22088-5.

ISO 22088-2:2006(E)
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 22088-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 6, Ageing,
chemical and environmental resistance.
It cancels and replaces ISO 6252:1992, which has been technically revised.
ISO 22088 consists of the following parts, under the general title Plastics — Determination of resistance to
environmental stress cracking (ESC):
⎯ Part 1: General guidance
⎯ Part 2: Constant tensile load method (replacement of ISO 6252:1992)
⎯ Part 3: Bent strip method (replacement of ISO 4599:1986)
⎯ Part 4: Ball or pin impression method (replacement of ISO 4600:1992)
⎯ Part 5: Constant tensile deformation method (new test method)
⎯ Part 6: Slow strain rate method (new test method)

1 Scope
This part of ISO 22088 specifies methods for the determination of environmental stress cracking (ESC) of
thermoplastics when they are subjected to a constant tensile load in the presence of chemical agents.
It is applicable to test specimens prepared by moulding and/or machining and can be used both for the
assessment of ESC of plastic materials exposed to different environments, and for the determination of ESC
of different plastic materials exposed to a specific environment.
This is essentially a ranking test and is not intended to provide data to be used for design or performance
prediction.
NOTE Methods for the determination of environmental stress cracking by means of a constant-strain test are
specified in ISO 22088-3, ISO 22088-4 and ISO 22088-5.
