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

ISO 11403-3:2014(E)
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 supplied 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 can be made. These data are not necessarily suitable for design.
[4][5]
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. Each 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 the material’s suitability for a particular application.
Some data are also considered adequate for undertaking predictions of performance in service and of
optimum processing conditions for moulding a component, although 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 standard test specimens, and the polymer structure in these specimens 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 applicability 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 cost 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 suitable for the acquisition of relevant information on many of these properties. For other properties,
however, ISO standards either do not exist or exhibit shortcomings that complicate their use at present
for the generation of comparable data (see Annex A). The standard has therefore been divided into parts
so that each part can be developed independently. In this way, additional properties can be included as
new or revised standards become available.

Plastics — Acquisition and presentation of comparable
multipoint data —
Part 3:
Environmental influences on properties
1 Scope
This part of ISO 11403 specifies test procedures for the acquisition and presentation of multipoint data
which demonstrate the behaviour of plastics under the following environments:
— prolonged exposure to heat;
— liquid chemicals;
— environmental stress cracking under a constant tensile stress;
— artificial weathering.
The tests are listed in order of increasing severity of the environment. By testing under the least severe
environments first, it is possible to make informed judgements regarding whether tests under more
severe conditions are worthwhile.

4 Specimen preparation
In the preparation of specimens by injection or compression moulding, the procedures described in
ISO 293, ISO 294-1, ISO 294-2, ISO 295, ISO 10724-1, ISO 10724-2 or ISO 1268 shall be used. The method
of moulding and the conditions depend on the material being moulded. If these conditions are specified
in the International Standard appropriate to the material, then they shall be adopted, where possible,
for the preparation of every specimen on which data are obtained using this part of ISO 11403. For those
plastics for which moulding conditions have not yet been standardized, the conditions employed shall
be within the range recommended by the polymer manufacturer and shall, for each of the processing
methods, be the same for every specimen. Where moulding conditions are not stipulated in any
International Standard, the values used for the parameters in Table 1 shall be recorded with the data
for that material.

5 Conditioning
For materials having properties that are significantly dependent upon the concentration of absorbed
water, specimens shall be in equilibrium with an atmosphere of (50 ± 5) % RH at 23 °C before exposure
to the environment, and for indicative property measurements prior to exposure (see the note) with
the exception of tests for prolonged exposure to heat (see 6.5). For these materials, consult the relevant
material standard for procedures for conditioning specimens. For materials with properties that are
not significantly sensitive to absorbed water, specimens shall be conditioned in accordance with the
International Standard appropriate to the material. If no materials standard is available, condition test
specimens at 23 °C ± 2 °C and (50 ± 10) % RH for a minimum length of time of 88 h (see ISO 291).
Reference to the use of any special conditioning shall be recorded with the data in the tables in Clause 7.
NOTE The water content may change during exposure to an environment, either through exposure to an
elevated temperature or, in the case of exposure to a chemical, through exchange of water with the chemical.
6 Test requirements
6.1 General
In acquiring data for the properties included in this part of ISO 11403, the exposure procedures described
in the corresponding ISO test standard for each property shall be followed.
Where tests are carried out at temperatures other than 23 °C, temperature values shall be chosen from
the series of integral multiples of 10 °C.
ISO 11403-3:2014(E)
6.2 Indicative properties and indicative data (see Clause A.1)
For each of the test requirements in 6.5 to 6.8, data shall be recorded as ratios of certain indicative
property values obtained at 23 °C before and after specified conditions of exposure. The tensile strength
and the tensile work to break are indicative properties that are common to each of the environmental
exposure tests. The tensile strength is either the yield stress σ or, for brittle materials, the stress at
Y
break σ (see ISO 527-1) and is determined by dividing the value for the force at yield or break by the
B
minimum initial cross-sectional area of the specimen in the waisted region. The tensile work to break
W (see 3.4) is determined from a conventional tensile test used to obtain the tensile strength and is
tB
normalized with respect to the minimum initial cross-sectional area of the specimen. In this part of
ISO 11403, all indicative data are recorded as a ratio of a measurement after exposure to a measurement
prior to exposure. It is therefore not necessary to specify units for indicative property measurements
but clearly these must be consistent throughout a series of measurements of each property.
6.3 Test specimens (see Clauses A.1 and A.2)
For the determination of indicative properties, either the ISO 20753 multipurpose test specimen
or the ISO 294-2 small tensile specimen (see Figure 1) may be used. The small specimen shall have
a thickness of 3 mm ± 0,1 mm and is recommended for materials that exhibit ductile failure prior to
exposure (see Clause A.1). The small specimen may be prepared by injection moulding (see ISO 294-2
for thermoplastics), or by machining the shape from sheet or compression moulded plates having a
thickness of 3 mm ± 0,1 mm (see ISO 2818)
