Plastics - Thermoplastic polyester (TP) moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties (ISO 7792-2:2012)
ISO 7792-2:2012 specifies the methods of preparation of test specimens and the standard test methods to be used in determining the properties of thermoplastic polyester moulding and extrusion materials. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given here.
Procedures and conditions for the preparation of test specimens in a specified state and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize thermoplastic polyester moulding and extrusion materials are listed.
The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide use, for or of particular significance to these moulding and extrusion materials, are also included in ISO 7792-2:2012, as are the designatory properties specified in ISO 7792-1 (viscosity number and tensile modulus of elasticity).
In order to obtain reproducible and comparable test results, it is necessary to use the methods of specimen preparation and conditioning, the specimen dimensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.

Dieser Teil von ISO 7792 legt die Verfahren zur Herstellung von Probekörpern und die zur Bestimmung der Eigenschaften für Formmassen thermoplastischer Polyester (TP) anzuwendenden Normprüfverfahren fest. Die Anforderungen an die Behandlung des Prüfmaterials und an die Konditionierung des Prüfmaterials vor der Formgebung der Probekörper und der Probekörper vor der Prüfung sind ebenfalls angegeben.
Verfahren und Bedingungen für die Herstellung der Probekörper in einem festgelegten Zustand sowie Verfahren für die Bestimmung der Eigenschaften der Formmassen, aus denen die Probekörper hergestellt werden, sind angegeben. Eigenschaften und Prüfverfahren, die anwendbar und notwendig sind, um die thermoplastischer Polyester Formmassen zu charakterisieren, sind aufgelistet.
Die Eigenschaften wurden aus den allgemein gültigen Prüfverfahren, wie sie in ISO 10350 1 festgelegt sind, ausgewählt. Andere weithin gebräuchliche Prüfverfahren oder solche von besonderer Bedeutung für diese Formmassen, wie die kennzeichnenden Eigenschaften aus Teil 1 dieser Norm (Viskositätszahl und Zugelastizitätsmodul), sind ebenfalls in diesen Teil von ISO 7792 aufgenommen.
Um reproduzierbare und vergleichbare Prüfergebnisse zu erhalten, ist es notwendig, die in dieser Norm fest-gelegten Verfahren für die Probekörperherstellung und konditionierung, die Probekörpermaße und die Prüf-verfahren anzuwenden. Die ermittelten Werte sind nicht unbedingt identisch mit denen, die an Probekörpern mit anderen Maßen oder an mit unterschiedlichen Verfahren hergestellten Probekörpern erhalten wurden.
Plastiques - Polyesters thermoplastiques (TP) pour moulage et extrusion - Partie 2: Préparation des éprouvettes et détermination des propriétés (ISO 7792-2:2012)
L'ISO 7792-2:2012 spécifie les méthodes de préparation des éprouvettes et les méthodes d'essai normalisées qui doivent être utilisées pour la détermination des propriétés des matériaux polyesters thermoplastiques (TP) pour moulage et extrusion. Les exigences relatives à la manipulation du matériau d'essai et au conditionnement du matériau d'essai avant moulage et des éprouvettes avant essai sont indiquées dans l'ISO 7792-2:2012.
Les modes opératoires et les conditions nécessaires à la préparation des éprouvettes dans un état défini, ainsi que les modes opératoires de mesure des propriétés des matériaux à partir desquels les éprouvettes sont obtenues sont donnés. Les propriétés et méthodes d'essai qui sont utiles et nécessaires pour caractériser les matériaux polyesters thermoplastiques pour moulage et extrusion sont énumérées.
Les propriétés ont été sélectionnées parmi les méthodes d'essai générales de l'ISO 10350 1. D'autres méthodes d'essai largement en usage ou ayant une signification particulière pour ces matériaux pour moulage et extrusion sont aussi incluses dans l'ISO 7792-2:2012; c'est le cas des propriétés de désignation spécifiées dans l'ISO 7792-1 (indice de viscosité et module d'élasticité en traction).
Dans le but d'obtenir des résultats d'essai reproductibles et comparables, il est nécessaire d'utiliser les méthodes de préparation et de conditionnement, les dimensions d'éprouvette ainsi que les modes opératoires d'essai spécifiés dans l'ISO 7792-2:2012. Les valeurs déterminées ne seront pas nécessairement identiques à celles obtenues en utilisant des éprouvettes de dimensions différentes ou préparées selon des modes opératoires différents.

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 7792-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9,
Thermoplastic materials.
This third edition cancels and replaces the second edition (ISO 7792-2:1997), which has been
technically revised.
ISO 7792 consists of the following parts, under the general title Plastics — Thermoplastic polyesters:

methods to be used in determining the properties of thermoplastic polyester moulding and extrusion
materials. Requirements for handling test material and for conditioning both the test material before
moulding and the specimens before testing are given here.
Procedures and conditions for the preparation of test specimens in a specified state and procedures for
measuring properties of the materials from which these specimens are made are given. Properties and
test methods which are suitable and necessary to characterize thermoplastic polyester moulding and
extrusion materials are listed.
The properties have been selected from the general test methods in ISO 10350-1. Other test methods in
wide use, for or of particular significance to these moulding and extrusion materials, are also included
in this part of ISO 7792, as are the designatory properties specified in part 1 (viscosity number and
tensile modulus of elasticity).
In order to obtain reproducible and comparable test results, it is necessary to use the methods of specimen
preparation and conditioning, the specimen dimensions and the test procedures specified herein. Values
determined will not necessarily be identical to those obtained using specimens of different dimensions
or prepared using different procedures.
