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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
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.
ISO 1872-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic
materials.
This third edition cancels and replaces the second edition (ISO 1872-2:1997), which has been technically
revised, and incorporates Amendment Amd.1:2000.
ISO 1872 consists of the following parts, under the general title Plastics — Polyethylene (PE) moulding and
extrusion materials:
— Part 1: Designation system and basis for specifications
— Part 2: Preparation of test specimens and determination of properties
INTERNATIONAL STANDARD ISO 1872-2:2007(E)

Part 2:
Preparation of test specimens and determination of properties
1 Scope
This part of ISO 1872 specifies the methods of preparation of test specimens and the test methods to be used
in determining the properties of polyethylene (PE) 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.
Procedures and conditions for the preparation of test specimens and procedures for measuring properties of
the materials from which these specimens are made are also given. Properties and test methods that are
suitable and necessary to characterize PE moulding and extrusion materials are listed.
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 part of
ISO 1872, as are the designatory properties specified in ISO 1872-1.
In order to obtain reproducible and comparable test results, it is necessary to use 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.

3 Preparation of test specimens
It is essential that specimens are always prepared by the same procedure (either injection moulding or
compression moulding), using the same processing conditions.
The procedure to be used for each test method is indicated in Tables 3 and 4 (M = injection moulding,
Q = compression moulding).
3.1 Treatment of the material before moulding
No pre-treatment of the material sample is normally necessary before processing.
3.2 Injection moulding
Injection moulding of test specimens is used for PE moulding materials having a melt mass-flow rate of
W 1 g/10 min, determined in accordance with ISO 1133:2005 using set of test conditions D (190 °C/2,16 kg).
Injection-moulded specimens shall be prepared in accordance with ISO 294-1 or ISO 294-3, using the
conditions specified in Table 1. It has been found that type A bar test specimens
