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.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
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 www .iso

This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9,
Thermoplastic materials.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/members .html.
This first edition of ISO 21301-2 cancels and replaces the second edition of ISO 4613-2:1995, which has
been technically revised to introduce a new designation system. It also incorporates the Amendment
ISO 4613-2:1995/Amd.1:2004. The main changes compared to the previous edition are as follows:
— the normative references has been updated;
— the contents and structures of Table 2 and Table 3 have been revised according to the revised
ISO 10350-1.
A list of all parts in the ISO 21301 series can be found on the ISO website.

INTERNATIONAL STANDARD ISO 21301-2:2019(E)
Plastics — Ethylene-vinyl acetate (EVAC) moulding and
extrusion materials —
Part 2:
Preparation of test specimens and determination of
properties
1 Scope
This document specifies the methods of preparation of test specimens and the test methods to be used
in determining the properties of ethylene/vinyl acetate (EVAC) 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 in this document.
This document gives 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 EVAC 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 are the designatory properties specified in ISO 21301-1.
The methods of preparation and conditioning, the specimen dimensions and the test procedures
specified 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.
