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.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 14663-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee
SC 9, Thermoplastic materials.
ISO 14663 consists of the following parts, under the general title Plastics — Ethylene/vinyl alcohol (EVOH)
copolymer moulding and extrusion materials:
— Part 1: Designation system and basis for specifications
— Part 2: Preparation of test specimens and determination of properties

Preparation of test specimens and determination of properties
1 Scope
This part of ISO 14663 specifies the methods of preparation of test specimens and the test methods to be used in
determining the properties of EVOH 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 here.
Procedures and conditions are described 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 EVOH moulding and extrusion materials are listed.
The properties have been selected from the general test methods in ISO 10350. 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 14663, as
is the designatory property specified in part 1: melt mass-flow rate.
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.

3 Preparation of test specimens
Specimens shall be prepared by injection moulding or by cutting from film. The method to be used is indicated in the
list of properties (Table 2) for each test specimen. The code letter M is used to show that injection moulding is to be
used; F is the code letter for film.
It is essential that specimens are always prepared using the same processing conditions. The standard conditions
are given below.
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.
3.1 Treatment of the material before moulding
Before processing, the moisture content of the sample shall not exceed 0,3 % (m/m). 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.
3.2 Injection moulding
Injection-moulded specimens shall be prepared in accordance with ISO 294-2, using the conditions specified in
Table 1.

3.3 Preparation of film specimens
Film specimens shall be cut from cast, blown or any other type of film. The recommended thickness is
20 mm ± 10 mm. 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 mm. The specimens shall have smooth
surfaces and shall be free from marks and other visible defects (streaks, pinholes, fish-eyes, etc.).

4 Conditioning of test specimens
Properties shall be determined on specimens in the dry-as-moulded state or on specimens in the moist state or on
specimens in either state. The state of the specimens shall be reported.
4.1 Dry-as-moulded (DAM) state
Specimens shall be moulded from dry granules (see 3.1 and 3.2). Specimens are considered to be in the dry-as-
moulded (DAM) state when they have been placed immediately after moulding in a moisture-proof container and
stored at 23 °C ± 2 °C for at least 24 h. The moisture content of DAM specimens may not exceed 0,3 % (m/m).
Drying of specimens with moisture contents above this limit in order to reach this moisture content is not allowed.
To keep the absorbed moisture at a low level, DAM specimens shall be tested in as short a
