Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
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. IS0
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 IS0 2898-2 was prepared by Technical Committee
ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials.
This third edition cancels and replaces the second edition
(IS0 2898,2:1989) and includes the following changes:
- the text has been brought into accordance with the standard SC 9
frame text;
- the test conditions for tensile stress and volume resistivity have been
revised in accordance with IS0 10350.
IS0 2898 consists of the following parts, under the general title Plastics -
Plasticized poly(vinyl chloride) (PVC-P) moulding and extrusion materials:
- Part 1: Designation system and basis for specifications
- Parf2: Preparation of test specimens and determination of
properties

INTERNATIONAL STANDARD @ IS0
Plastics - Plasticized poly(vinyl chloride) (PVC-P) moulding
and extrusion materials -
Part 2:
Preparation of test specimens and determ ination of properties
1 Scope
This part of IS0 2898 specifies the methods of preparation of test specimens and the test methods to be used in
determining the properties of PVC-P 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 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 PVC-P moulding and extrusion materials are listed.
The properties have been selected from the general test methods in IS0 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 IS0 2898,
as are the designatory properties specified in part 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 (compression moulding), using the same
processing conditions.
The material shall be kept in moisture-proof containers until it is required for use.
3.1 Treatment of the material before moulding
Before processing, no pretreatment of the material sample is normally necessary.
3.2 Compression moulding
Before compression moulding, the material shall be plasticized using a two-roll mill under the conditions specified
in table 1.
