Plastics - Thermoplastic polyester (TP) moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties (ISO 20028-2:2017)

ISO 20028-2:2017 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.
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 document, as are the designatory properties specified in ISO 20028-1 (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.

Kunststoffe - Thermoplastische Polyester (TP)-Formmassen - Teil 2: Herstellung von Probekörpern und Bestimmung von Eigenschaften (ISO 20028-2:2017)

Dieses Dokument legt die Verfahren zur Herstellung von Probekörpern und die zur Bestimmung der Eigen-schaften thermoplastischer Polyester (TP) Werkstoffe anzuwendenden Normprüfverfahren fest. Die An-forderungen an die Behandlung des Prüfmaterials und an das Konditionieren des Prüfmaterials sowohl vor dem Formen der Probekörper als auch der Probekörper vor der Prüfung sind angegeben.
Verfahren und Bedingungen für die Herstellung der Probekörper in einem festgelegten Zustand sowie Ver-fahren für die Bestimmung der Eigenschaften der Werkstoffe, aus denen die Probekörper hergestellt werden, sind angegeben. Eigenschaften und Prüfverfahren, die anwendbar und notwendig sind, um den thermoplastischen Polyester Werkstoff zu charakterisieren, sind aufgelistet.
Die Eigenschaften wurden aus den allgemeinen Prüfverfahren in ISO 10350-1 ausgewählt. Andere weithin gebräuchliche Prüfverfahren oder solche, die von besonderer Bedeutung für diese Werkstoffe sind, sowie die kennzeichnenden Eigenschaften in ISO 20028-1 (Viskositätszahl und Zugelastizitätsmodul), sind ebenfalls in diesem Dokument enthalten.
Um reproduzierbare und vergleichbare Prüfergebnisse zu erhalten, ist es notwendig, die in dieser Norm festgelegten Verfahren für die Herstellung und Konditionierung der Probekörper, die Probekörpermaße und die Prüfverfahren anzuwenden. Die ermittelten Werte sind nicht unbedingt identisch mit denen, die an Probe¬körpern 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 20028-2:2017)

ISO 20028-2:2017 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.
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 le présent document; c'est le cas des propriétés de désignation spécifiées dans l'ISO 20028‑1 (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 ici. 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.

Polimerni materiali - Materiali za oblikovanje in ekstrudiranje iz plastomernih poliestrov - 2. del: Priprava preskušancev in ugotavljanje lastnosti (ISO 20028-2:2017)

Ta dokument določa metode za pripravo preskušancev in standardnih preskusnih metod za uporabo pri ugotavljanju lastnosti materialov iz termoplastnih poliestrov za oblikovanje in ekstrudiranje. Podane so zahteve za ravnanje s preskusnim materialom ter za obdelavo preskusnega materiala pred oblikovanjem in obdelavo preskušancev pred preskusom.
Podani so postopki in pogoji za pripravo preskušancev v določenem stanju in postopki za merjenje lastnosti materialov, iz katerih so preskušanci izdelani. Navedene so lastnosti in preskusne metode, ki so primerne in nujne za opredelitev navedenih materialov za oblikovanje in ekstrudiranje iz plastomernih poliestrov.
Lastnosti so bile izbrane na podlagi splošnih preskusnih metod iz standarda ISO 10350-1. Druge preskusne metode, ki so v splošni uporabi ali posebej pomembne za te materiale za oblikovanje in ekstrudiranje, so prav tako vključene v ta dokument. Vključene so tudi označevalne lastnosti, ki so navedene v standardu ISO 20028-1 (viskoznostno število in natezni modul elastičnosti).
Da se zagotovijo primerljivi in ponovljivi rezultati preskusa, je potrebno uporabljati metode priprave in obdelave, mere preskušanca ter preskusne postopke, ki so navedeni v tem delu. Pri tem ni nujno, da bodo ugotovljene vrednosti enake tistim, ki so pridobljene z uporabo preskušancev, ki imajo drugačne mere ali so pripravljeni z uporabo drugih postopkov.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
