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.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information

ISO 18263 consists of the following parts, under the general title Plastics — Mixtures of polypropylene
(PP) and polyethylene (PE) recyclate derived from PP and PE used for flexible and rigid consumer packaging:

INTERNATIONAL STANDARD ISO 18263-2:2015(E)
Plastics — Mixtures of polypropylene (PP) and
polyethylene (PE) recyclate derived from PP and PE used
for flexible and rigid consumer packaging —
Part 2:
Preparation of test specimens and determination of
properties
1 Scope
This part of ISO 18263 specifies methods of preparation of test specimens and the standard test
methods to be used in determining the properties of mixtures of polypropylene (PP) and polyethylene
(PE) recyclate derived from PP and PE used for flexible and rigid consumer packaging for moulding and
extrusion. Recyclate from packaging used for the transport, handling, or storage of hazardous goods
is not to be used. Since it is impossible to get the information about stabilizer levels of recyclate, it is
necessary to add stabilizer as needed. Requirements for handling test material and for conditioning both
the test material before moulding and the specimens before testing are given in this part of ISO 18263.
