Plastics - Polyoxymethylene (POM) moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties (ISO 29988-2:2018)
This document specifies the methods of preparation of test specimens and the test methods to be used
in determining the properties of polyoxymethlene (POM) moulding and extrusion materials.
Requirements for handling test materials and for conditioning both the test materials before moulding
and the specimens before testing are specified. Procedures and conditions for the preparation of test
specimens 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 POM moulding and
extrusion materials are listed. The properties have been selected from the general test methods. 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: melt flow rate and tensile modulus.
In order to obtain reproducible and comparable test results, it is intended to use the methods of
preparation and conditioning, the specimen dimensions and the test procedures specified in this
document. Values determined will not necessarily be identical to those obtained using specimens of
different dimensions or prepared using different procedures.
Kunststoffe - Polyoxymethylen (POM)-Werkstoffe - Teil 2: Herstellung von Probekörpern und Bestimmung von Eigenschaften (ISO 29988-2:2018)
1.1 Dieser Teil der ISO 29988 legt die Verfahren zur Herstellung von Probekörpern und die anzuwendenden Prüfverfahren zur Bestimmung der Eigenschaften von POM Werkstoffen fest. Die Anforderungen hinsichtlich der Handhabung des Probematerials und hinsichtlich der Konditionierung des Probematerials vor der Formgebung und der Probekörper vor dem Prüfen werden angegeben.
1.2 Verfahren und Eigenschaften für die Herstellung von Probekörpern und Prüfverfahren zur Ermittlung der Eigenschaften der Werkstoffe, aus denen diese Exemplare bestehen, werden definiert. Eigenschaften und Prüfverfahren, die zur Charakterisierung von POM-Werkstoffen geeignet und notwendig sind, werden aufgeführt.
1.3 Die Eigenschaften wurden aus den in den allgemeinen Prüfverfahren in ISO 10350 1 ausgewählt. Weitere Prüfmethoden, die für Werkstoffe breite Anwendung finden oder für diese von besonderer Signifikanz sind, sind ebenfalls in diesem Teil der ISO 29988 enthalten, ebenso wie die spezifizierten Eigenschaften in der ISO 29988 1: Schmelzefließrate und Zugmodul.
1.4 Um reproduzierbare und vergleichbare Prüfergebnisse zu erhalten, müssen die hierin festgelegten Verfahren zur Probekörperherstellung und konditionierung, die Probekörpermaße und die Prüfverfahren eingehalten werden. Die bestimmten Werte werden nicht zwangsläufig mit denen identisch sein, die für Probekörper mit anderen Maßen oder für nach anderen Verfahren hergestellte Probekörper erhalten werden.
Plastiques - Matériaux à base de polyoxyméthylène (POM) pour moulage et extrusion - Partie 2: Préparation des éprouvettes et détermination des propriétés (ISO 29988-2:2018)
L'ISO 29988-2:2018 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 polyoxyméthylène (POM).
Les exigences relatives à la manipulation des matériaux d'essai et au conditionnement des matériaux d'essai avant moulage et des éprouvettes avant essai sont spécifiées. 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 sont donnés.
Les propriétés et méthodes d'essai qui sont utiles et nécessaires pour caractériser les matériaux pour moulage et extrusion à base de POM sont énumérées. Les propriétés ont été sélectionnées parmi les méthodes d'essai générales. 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: indice de fluidité à chaud et module en traction.
Dans le but d'obtenir des résultats d'essai reproductibles et comparables, on est censé utiliser les méthodes de préparation et de conditionnement, les dimensions d'éprouvette ainsi que les modes opératoires d'essai spécifiés dans le présent document. 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 na osnovi polioksimetilena (POM) za oblikovanje in ekstrudiranje - 2. del: Priprava preskušancev in ugotavljanje lastnosti (ISO 29988-2:2018)
Ta dokument določa metode za pripravo preskušancev in preskusnih metod za uporabo pri ugotavljanju lastnosti materialov na osnovi polioksimetilena (POM) za oblikovanje in ekstrudiranje.
Podane so zahteve za ravnanje s preskusnimi materiali ter za obdelavo preskusnih materialov pred oblikovanjem in obdelavo preskušancev pred preskusom. Podani so postopki in pogoji za pripravo preskušancev ter postopki za merjenje lastnosti materialov, iz katerih so izdelani preskušanci.
Navedene so lastnosti in preskusne metode, ki so primerne in nujne za opredelitev materialov na osnovi polioksimetilena za oblikovanje in ekstrudiranje. Lastnosti so bile izbrane na podlagi splošnih preskusnih metod. 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: pretok taline in natezni moduli. Da se zagotovijo primerljivi in ponovljivi rezultati preskusa, naj se uporabljajo metode priprave in obdelave, mere preskušanca ter preskusni postopki, ki so določeni v tem dokumentu. 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
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following
