ISO 11403-3:2021(E)
Introduction
This document 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 document 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.
[7][8]
The ISO 10350 series 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. This
document 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 document. 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 are often 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 document 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 are not suitable for accurate design calculations for product performance. The
material supplier should be consulted for specific information on the applicability of data.
The ISO 10350 series together with the ISO 11403 series define the means for acquiring and presenting
a core set of comparable data for use in material selection. Use of these International Standards should
result in a rationalization of effort and a reduction of cost associated with provision of these data.
Furthermore, reference to these International Standards 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 document. 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
document.
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 ISO 11403 series 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 document 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.

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 document.
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 ± 2) °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 ± 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 can 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 document, 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 11403-3:2021(E)
6.2 Indicative properties and indicative data
See A.2.
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
Y
at break σ (see ISO 527-1) and is determined by dividing the value for the force at yield or break by
B
the minimum initial cross-sectional area of the specimen in the waisted region. The tensile work to
break W 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 document,
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 shall be consistent throughout a series of measurements of each property.
6.3 Test specimens
See A.2 and A.3.
For the determination of indicative properties, either the ISO 20753/A11 multipurpose test specimen or
the ISO 20753/CW13 (or CW23) 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 A.2). 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). Where appropriate, the moulding conditions specified in
the relevant material standard shall be used. For the determination of environm
