Plastics - Polyethylene (PE) moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties (ISO 17855-2:2016)

ISO 17855-2:2016 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of polyethylene (PE) 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 and procedures for measuring properties of the materials from which these specimens are made are also given. Properties and test methods that are suitable and necessary to characterize PE 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 17855, as are the designatory properties specified in ISO 17855‑1.
In order to obtain reproducible and comparable test results, it is necessary to use the methods of 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 - Polyethylen (PE)-Formmassen - Teil 2: Herstellung von Probekörpern und Bestimmung von Eigenschaften (ISO 17855-2:2016)

Dieser Teil von ISO 17855 legt die Verfahren zur Herstellung von Probekörpern und die zu verwendenden Prüfverfahren zur Bestimmung der Eigenschaften von Polyethylen (PE)-Formmassen fest. Anforderungen an die Behandlung des Probematerials und an das Konditionieren des Probematerials sowohl vor dem Formen der Probekörper als auch der Probekörper vor der Prüfung sind enthalten.
Verfahren und Bedingungen für die Herstellung der Probekörper und Verfahren für die Bestimmung der Eigenschaften der Werkstoffe, aus denen die Probekörper hergestellt werden, sind ebenfalls angegeben. Eigenschaften und Prüfverfahren, die anwendbar und notwendig sind, um Polyethylen (PE)-Formmassen zu charakterisieren, sind aufgelistet.
Die Eigenschaften stammen aus den allgemeinen Prüfverfahren, wie sie in ISO 10350-1 festgelegt sind. Andere weithin gebräuchliche Prüfverfahren oder solche von besonderer Bedeutung für diese Formmassen sind ebenfalls in diesen Teil von ISO 17855 aufgenommen, wie auch die kennzeichnenden Eigenschaften aus ISO 17855-1.
Um reproduzierbare und vergleichbare Prüfergebnisse zu erhalten, ist es erforderlich, die Probekörper-herstellung und -konditionierung, die Probekörperabmessungen sowie die Prüfverfahren wie hier festgelegt anzuwenden. Die gemessenen Werte müssen nicht notwendigerweise mit denen identisch sein, die bei Anwendung von Probekörpern anderer Abmessungen oder solchen, die mit einem anderen Verfahren hergestellt wurden, erhalten werden.

Plastiques - Polyéthylène (PE) pour moulage et extrusion - Partie 2: Préparation des éprouvettes et détermination des propriétés (ISO 17855-2:2016)

ISO 17855-2:2016 spécifie les méthodes de préparation des éprouvettes et les méthodes d'essai à mettre en ?uvre afin de déterminer les propriétés des PE pour moulage et extrusion. Elle indique les exigences requises lors de la manipulation du matériau d'essai, ainsi que lors du conditionnement dudit matériau avant moulage et des éprouvettes avant l'essai.
Elle précise 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 ces éprouvettes sont fabriquées. Elle répertorie également les propriétés et les méthodes d'essai appropriées et nécessaires à la caractérisation des PE pour moulage et extrusion.
Les propriétés ont été choisies à partir des méthodes d'essai générales données dans l'ISO 10350‑1. D'autres méthodes d'essai, présentant une importance particulière ou largement utilisées dans le cas de ces matériaux pour moulage et extrusion sont également incluses dans la présente partie de l'ISO 17855, de même qu'elles figurent dans les propriétés de désignation de l'ISO 17855‑1.
Pour obtenir des résultats d'essai reproductibles et comparables, il est nécessaire d'utiliser les méthodes de préparation et de conditionnement, ainsi que les dimensions d'éprouvettes et les modes opératoires d'essai spécifiés ci-après. Les valeurs ainsi 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 - Polietilenski (PE) materiali za oblikovanje in ekstrudiranje - 2. del: Priprava preskušancev in ugotavljanje lastnosti (ISO 17855-2:2016)

Ta del standarda ISO 17855 določa metode za pripravo preskušancev in preskusnih metod, ki se uporabljajo za ugotavljanje lastnosti polietilenskih (PE) materialov 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 tudi postopki in pogoji za pripravo preskušancev ter postopki za merjenje lastnosti materialov, iz katerih so preskušanci izdelani. Navedene so lastnosti in preskusne metode, ki so primerne in nujne za opredelitev polietilenskih materialov za oblikovanje in ekstrudiranje. Lastnosti so bile izbrane na podlagi splošnih preskusnih metod iz standarda ISO 10350-1. Druge preskusne metode, ki so v splošni uporabi ali so posebej pomembne za te materiale za oblikovanje in ekstrudiranje, so prav tako vključene v ta del standarda ISO 17855. Vključene so tudi označevalne lastnosti, ki so določene v standardu ISO 17855-1. Da se zagotovijo primerljivi in ponovljivi rezultati preskusa, je treba 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).
Any trade name used in this document is information given for the convenience of users and does not
