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. Esch 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
(1 EC) 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 ISO 11403-1 was prepared by Technical Committee
lSO/TC 61, Plastics, Subcommittee SC 1, Terminology.
ISO 11403 consists of the following Parts, und er the ge neral title Plastics
- Acquisition and presentation of comparable m ultipoin t data:
- Part 1: Mechanical properties
- Part 2: Thermal and processing properties
- Part 3: Environmental influences on properties

Introduction
This International Standard has been prepared because users of plastics
find sometimes that available data cannot be used readily to compare the
properties of similar materials, especially when the data have been sup-
plied by different sources. Even when the same Standard tests have been
used, they often allow the adoption of a wide range of alternative test
conditions, and the data obtained are not necessarily comparable. The
purpose of this International Standard is to identify specific methods and
conditions of test to be used for the acquisition and presentation of data
in Order that valid comparisons between materials tan be made.
ISO 10350 is concerned with Single-Point data. Such data represent the
most basic method for characterizing materials and are useful for the initial
stages of material selection. The present International Standard identifies
test conditions and procedures for the measurement and presentation of
a more substantial quantity of data. Esch property here is characterized
by multipoint data which demonstrate how that property depends upon
important variables such as time, temperature and environmental effects.
Additional properties are also considered in this Standard. These data
therefore enable more discriminating decisions to be made regarding a
material’s suitability for a par-ticular application. Some data are also con-
sidered adequate for undertaking predictions of Performance in Service
and of Optimum processing conditions for moulding a component, al-
though it should be recognized that, for purposes of design, additional data
will often be needed. One reason for this is that some properties are
strongly dependent upon the physical structure of the material. The test
procedures referred to in this Standard employ, where possible, the
multipurpose tensile bar, and the polymer structure in this test specimen
may be significantly different from that in specific regions of a moulded
component. Under these circumstances, therefore, the data will not be
suitable for accurate design calculations for product Performance. The
material supplier should be consulted for specific information on the ap-
plicability of data.
ISO 10350 and the various Parts of this International Standard together
define the means for acquiring and presenting a core set of comparable
data for use in material selection. Use of these Standards should result in
a rationalization of effort and a reduction of tost associated with Provision
of these data. Furthermore, reference to these Standards will simplify the
development of data models for the computerized storage and exchange
of data concerning material properties.
Where appropriate, values for test variables have been specified by this
Standard. For some tests however, owing to the wide range of conditions
over which different plastics perform, the Standard gives guidance in the
selection of certain test conditions so that they cover the operating range
for that polymer. Because, in general, the properties and Performance
specifications for different Polymers differ widely, there is no Obligation to
generate data under all the test conditions specified in this Standard.

Data on a wide range of properties are needed to enable plastics to be
selected and used in the large variety of applications to which they are
suited. ISO Standards describe experimental procedures which are suit-
able for the acquisition of relevant information on many of these proper-
ties. For other properties, however, ISO Standards either do not exist or
exhibit shortcomings that complicate their use at present for the gener-
ation of comparable data (see annex A). The Standard has therefore been
divided into Parts so that each patt tan be developed independently. In this
way, additional properties tan be included as new or revised Standards
become available.
