Plastics - Ethylene/vinyl alcohol (EVOH) copolymer moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties (ISO 21309-2:2019)

This document specifies the methods of preparation of test specimens and the test methods to be used
in determining the properties of ethylene/vinyl alcohol (EVOH) copolymer moulding and extrusion
materials. It gives requirements for handling test material and for conditioning both the test material
before moulding and the specimens before testing.
This document describes 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 EVOH moulding and extrusion
materials are listed in this document.
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 is the melt mass-flow rate designatory property specified in ISO 21309-1.
In order to obtain reproducible and comparable test results, it is intended 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.

Plastiques - Matériaux à base de copolymères éthylène/alcool vinylique (EVOH) pour moulage et extrusion - Partie 2: Préparation des éprouvettes et détermination des propriétés (ISO 21309-2:2019)

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 à base de copolymères éthylène/alcool vinylique (EVOH) pour moulage et extrusion. Il donne des 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 décrit 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 d'EVOH sont énumérées dans le présent document.
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 de la propriété de désignation de l'indice de fluidité à chaud en masse spécifiée dans l'ISO 21309‑1.
Dans le but d'obtenir des résultats d'essai reproductibles et comparables, on doit 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.

Ta dokument določa metode za pripravo preskušancev in preskusnih metod za uporabo pri ugotavljanju lastnosti materialov na osnovi kopolimera etilen/vinilalkohol (EVOH) za oblikovanje in ekstrudiranje. Podaja zahteve za ravnanje s preskusnim materialom ter obdelavo preskusnega materiala pred oblikovanjem in obdelavo preskušancev pred preskusom.
Ta dokument opisuje postopke in pogoje za pripravo preskušancev in postopkov za merjenje lastnosti materialov, iz katerih so izdelani preskušanci. V tem dokumentu so navedene lastnosti in preskusne metode, ki so primerne in nujne za opredelitev materialov na osnovi kopolimera etilen/vinilalkohol (EVOH) 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 dokument. Vključena je tudi označevalna lastnost masnega pretoka taline, določena v standardu ISO 21309-1.
Da se zagotovijo primerljivi in ponovljivi rezultati preskusa, je treba uporabljati metode priprave in obdelave preskušancev, 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).

4 Preparation of test specimens
4.1 General
Specimens shall be prepared by injection moulding or by cutting from film. The method to be used is
indicated in the list of properties (see Table 2) for each test specimen.
It is essential that specimens are always prepared using the same processing conditions. The material
shall be kept in moisture-proof containers until it is required for use.
The moisture content of filled or reinforced materials shall be expressed as a percentage of the total
mass of the compound.
4.2 Treatment of the material before moulding
Before processing, the moisture content of the sample shall not exceed 0,3 % (mass fraction). If
the moisture level exceeds this limit, the material shall be dried for 24 h ± 2 h at a temperature of
105 °C ± 5 °C in vacuo or in a stream of dried nitrogen.
To ensure that the moisture content remains low, it is recommended that the material in the feed hopper
of the injection-moulding machine be blanketed with any suitable gas (dried air, nitrogen or argon, for
example). Better results may be obtained using a dehumidifier hopper dryer.
4.3 Injection moulding
Injection-moulded specimens shall be prepared in accordance with ISO 294-2, using the conditions
specified in Table 1.

4.4 Preparation of film specimens
Film specimens shall be cut from cast, blown or any other type of film. The recommended thickness is
20 µm ± 10 µm. The thickness of the specimens shall be determined from the average thickness of the
sample, measured mechanically. The variation in thickness shall not exceed 2 µm. The specimens shall
have smooth surfaces and shall be free from marks and other visible defects (streaks, pinholes, fish-
eyes, etc.).
