Plastics - Ultra-high-molecular-weight polyethylene (PE-UHMW) moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties (ISO 21304-2:2021)

This document specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of PE-UHMW moulding and extrusion materials. It gives the requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing.
This document gives the procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made. Properties and test methods which are suitable and necessary to characterize PE-UHMW 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 21304-1. This document specifies the materials with MFR less than 0,1 g/10 min at 190 °C /21,6 kg based on ISO 17855-1.
The methods of preparation and conditioning, the specimen dimensions and the test procedures specified in this document are used in order to obtain reproducible and comparable test results. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.

Kunststoffe - Ultrahochmolekulare Polyethylen (PE-UHMW)-Formmassen - Teil 2: Herstellung von Probekörpern und Bestimmung von Eigenschaften (ISO 21304-2:2021)

Dieses Dokument legt die Verfahren zur Herstellung von Probekörpern und die zur Bestimmung der Eigenschaften von PE UHMW Formmassen anzuwendenden Prüfverfahren fest. Es enthält die Anforderungen an die Behandlung des Probenmaterials und an das Konditionieren sowohl des Probenmaterials vor der Herstellung als auch der Probekörper vor der Prüfung.
Dieses Dokument enthält die Verfahren und Bedingungen für die Herstellung der Probekörper und Verfahren zur Bestimmung der Eigenschaften der Werkstoffe, aus der die Probekörper hergestellt werden. Eigenschaften und Prüfverfahren, die anwendbar und notwendig sind, um PE UHMW Formmassen zu charakterisieren, sind aufgelistet.
Die Eigenschaften wurden aus den in ISO 10350 1 angegebenen allgemeinen Prüfverfahren ausgewählt. Andere weithin gebräuchliche Prüfverfahren oder solche von besonderer Bedeutung für diese Formmassen sind, wie auch die in ISO 21304 1 festgelegten kennzeichnenden Eigenschaften, ebenfalls in diesem Dokument enthalten. Dieses Dokument legt die Werkstoffe mit einer MFR (Schmelze-Massefließrate, en: melt mass-flow rate) von weniger als 0,1 g/10 min bei 190 °C/21,6 kg nach ISO 17855 1 fest.
Die in diesem Dokument festgelegten Verfahren für die Herstellung und Konditionierung, Probekörpermaße und Prüfverfahren werden angewendet, um reproduzierbare und vergleichbare Prüfergebnisse zu erhalten. Die ermittelten Werte sind nicht notwendigerweise mit denen identisch, die bei Anwendung von Probekörpern anderer Maße oder solchen, die mit einem anderen Verfahren hergestellt wurden, erhalten werden.

Plastiques - Matériaux à base de polyéthylène à très haute masse moléculaire (PE-UHMW) pour moulage et extrusion - Partie 2: Préparation des éprouvettes et détermination des propriétés (ISO 21304-2:2021)

Le présent document spécifie les méthodes de préparation des éprouvettes et les méthodes d'essai qui doivent être utilisées pour la détermination des propriétés des matériaux pour moulage et extrusion à base de PE-UHMW. Il donne les exigences relatives à la manipulation du matériau d'essai et au conditionnement du matériau d'essai avant moulage et des éprouvettes avant essai.
Le présent document donne les modes opératoires et les conditions nécessaires à la préparation des éprouvettes, ainsi que les modes opératoires de mesure des propriétés des matériaux à partir desquels les éprouvettes sont obtenues. Les propriétés et méthodes d'essai qui sont utiles et nécessaires pour caractériser les matériaux pour moulage et extrusion à base de PE-UHMW sont énumérées.
Les propriétés ont été sélectionnées parmi les méthodes d'essai générales de l'ISO 10350‑1. D'autres méthodes d'essai largement utilisées ou qui revêtent une importance 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 21304‑1. Le présent document spécifie les matériaux avec un MFR inférieur à 0,1 g/10 min à 190 °C /21,6 kg selon l'ISO 17855‑1.
Les méthodes de préparation et de conditionnement, les dimensions d'éprouvette ainsi que les modes opératoires d'essai spécifiés dans le présent document sont utilisés dans le but d'obtenir des résultats d'essai reproductibles et comparables. 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.
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).

This first edition of ISO 21304-2 cancels and replaces ISO 11542-2:1998, which has been technically
revised. It also incorporates the Technical Corrigendum ISO 11542-2:1998/Cor 1:2007.
The main changes compared to the previous edition are as follows:
— updated the normative references to the latest version;
— added terms and definitions (see Clause 3);
— revised the contents and structures of Table 2 and Table 3 according to the revised ISO 10350-1;
— added new Annex A;
— revised the masses of weights used to load specimen in Table B.1 (former Table A.1);
— revised Figure B.1, Figure B.2, Figure B.3 and Figure C.1 (former Figures A.1, A.2, A.3 and B.1).
