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.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9,
Thermoplastic materials.
This second edition cancels and replaces the first edition (ISO 17855-2:2016(E)), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— ISO 16241, ISO18488, ISO 18489 and ISO 22088-2 have been integrated to Clause 2;
— Table 1 Conditions for injection moulding of test specimens have been changed;
— Table 2 Conditions for compression moulding of test specimens have been changed;
— Properties from ISO 16241, ISO18488, ISO 18489 and ISO 22088-2 have been integrated in Table 4;
— Annex A (informative) is deleted .
A list of all parts in the ISO 17855 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

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 methodsfor
determining the properties of polyethylene (PE) moulding and extrusion materials. It establishes
general principles for handling test material and for conditioning both the test material before moulding
and the specimens before testing.
This document specifies the procedures and conditions for the preparation of test specimens and
procedures for measuring properties of the materials from which these specimens are made. It gives
guidance on properties and test methods that are suitable and essential to characterize PE materials
for injection moulding and extrusion.
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 17855-1.
In order to obtain reproducible and comparable test results, it give guidance on using 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.
