Plastics - Acquisition and presentation of comparable multipoint data - Part 3: Environmental influences on properties (ISO 11403-3:2021)
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.
Kunststoffe - Ermittlung und Darstellung von vergleichbaren Vielpunkt-Kennwerten - Teil 3: Umgebungseinflüsse auf Eigenschaften (ISO 11403-3:2021)
Dieses Dokument legt Prüfverfahren für die Ermittlung und Darstellung von Vielpunkt Kennwerten fest, die das Verhalten von Kunststoffen gegenüber den folgenden Umgebungseinflüssen darstellen:
- langanhaltende Wärmeeinwirkung;
- flüssige Chemikalien;
- umgebungsbedingte Spannungsrissbildung unter konstanter Zugspannung;
- künstliche Bewitterung.
Die Prüfungen sind in der Reihenfolge zunehmender Schärfe der Umgebungseinflüsse aufgeführt. Durch anfängliche Prüfung bei den am wenigsten scharfen Umgebungseinflüssen ist es möglich, fundierte Entscheidungen zu treffen, ob Prüfungen unter schärferen Bedingungen sinnvoll sind.

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.

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.

---------------------- Page: 15 ----------------------
SIST EN ISO 11403-3:2021
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 environmental stress cracking
resistance (see 6.7), the multipurpose test specimen shall be used, machined where necessary as shown
in Figure 2 (see also A.5).
6.4 Test speed
For polymers that, prior to exposure, show no yielding and have a strain at break ε less than or equal
B
to 10 % when tested at a speed of 50 mm/min (see ISO 527-1), a test speed of 5 mm/min ± 1 mm/min
shall be used with the multipurpose test specimen and 1 mm/min ± 0,2 mm/min with the small tensile
specimen. For materials that yield, or where ε > 10 % before exposure, these speeds shall be 50 mm/
B
min ± 10 mm/min and 10 mm/min ± 2 mm/min respectively for the two specimen types.
The test speeds for indicative property measurements after exposure to the environment shall be the
same as those adopted for tests prior to exposure and shall be recorded with the data in Clause 7.
6.5 Prolonged exposure to heat: ISO 2578
For materials that absorb moisture, specimens shall be as moulded and contained so as to avoid changes
in water content prior to all thermal exposures and reference tests.
The indicative properties are:
— 1: the tensile strength σ or σ (see 6.2);
Y B
— 2: the tensile work to break W (see 6.2).
tB
Determine the reference values of each indicative property at (23 ± 2) °C, using a minimum of five
specimens (see also 6.4).
Expose specimens to elevated temperatures selected to enable thermal endurance profiles to be
determined.
After exposure, specimens shall be stored at (23 ± 2) °C for between 16 h and 96 h before the
measurement of indicative properties. For materials that absorb moisture, the specimens shall be

sealed during this time interval in order to prevent any change in the moisture content. Determine the
thermal endurance graphs corresponding to a threshold value of 50 % of each indicative property. A
minimum of five specimens shall be used at each exposure time, a minimum of five exposure times for
each indicative property at each temperature and a minimum of four temperatures for determining the
profile for each property.
NOTE Some of the exposure times can yield results that can be used for the determination of both of the
property profiles.

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 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.

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 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/DIS 11403-3:2020(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 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 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). Where appropriate, the moulding conditions specified in
part 2 of the relevant material standard shall be used. For the determination of environmental stress
cracking resistance (6.7), the multipurpose test specimen shall be used, machined where necessary as
shown in Figure 2 (see also Clause A.5).
6.4 Test speed
For polymers that, prior to exposure, show no yielding and have a strain at break ε less than or equal
B
to 10 % when tested at a speed of 50 mm/min (see ISO 527-1), a test speed of 5 mm/min ± 1 mm/min
shall be used with the multipurpose test specimen and 1 mm/min ± 0,2 mm/min with the small tensile
specimen. For materials that yield, or where ε . 10 % before exposure, these speeds shall be 50 mm/
B
min ± 10 mm/min and 10 mm/min ± 2 mm/min respectively for the two specimen types.
The test speeds for indicative property measurements after exposure to the environment shall be the
same as those adopted for tests prior to exposure and shall be recorded with the data in Clause 7.
6.5 Prolonged exposure to heat: ISO 2578
For materials that absorb moisture, specimens shall be as-moulded and contained so as to avoid changes
in water content prior to all thermal exposures and reference tests.
The indicative properties are:
— 1 the tensile strength σ or σ (see 6.2);
Y B
— 2 the tensile work to break W (see 6.2).
tB
Determine reference values of each indicative property at 23 °C ± 2 °C, using a minimum of five
specimens (see also 6.4).
Expose specimens to elevated temperatures selected to enable thermal endurance profiles to be
determined.
After exposure, specimens shall be stored at 23 °C ± 2 °C for between 16 h and 96 h before the
measurement of indicative properties. For materials that absorb moisture, the specimens shall be
sealed during this time interval in order to prevent any change in the moisture content. Determine the
thermal endurance graphs corresponding to a threshold value of 50 % of each indicative property. A
minimum of five specimens shall be used at each exposure time, a minimum of five exposure times for

6.6 Liquid chemicals: ISO 175
To aid comparability of data generated for different materials and from different sources, this document
requires that materials be exposed to the chemicals listed in Table B.1. If particular materials are not
recommended for use, or are not used, in the presence of any of these chemicals at the temperature
specified, then the letters NR (not recommended) shall be given in place of experimental data (see
Table 3).
Although not part of the comparable core data defined above, results for exposure to other chemicals
may be presented in addition. It is recommended that, for this purpose, the chemicals be chosen from
the list given in ISO 175.

The indicative properties are:
— 1 the tensile strength σ or σ (see 6.2);
Y B
— 2 the tensile work to break W (see 6.2);
tB
— 3 the length l of the specimen and its thickness h in the centre of the waist (see Figure 1);
— 4 the mass m of the specimen.
Measure reference values at 23 °C ± 2 °C (prior to exposure to the chemical), using a minimum of five
specimens for properties 1 and 2 (see also 6.4) and, additionally, a minimum of four different specimens
for properties 3 and 4.
Immerse specimens in the chemical for periods of 100 h and 1 000 h at the temperature specified
in Table B.1 (see the note). For exposure tests carried out at 23 °C, measure indicative properties
immediately after exposure. If the exposure has been carried out at an elevated temperature, immerse
the specimens in fresh chemical at 23 °C for 20 min ± 10 min and then immediately measure the
indicative properties.
NOTE To avoid unnecessary long-term testing, it is recommended that exploratory tests be carried out to
determine the influence of the temperature and the chemical acting alone.
Use a minimum of five specimens for each exposure time for properties 1 and 2. Of the four specimens
used to determine reference values for properties 3 and 4, use two specimens to determine properties
3 and 4 after 100 h immersion and the remaining two specimens to determine the properties after
1 000 h immersion. The specimens used to obtain properties 3 and 4 may subsequently be used to
obtain properties 1 and 2.
The presentation of results at additional temperatures is optional. In each additional test, in order
to maximize the precision of indicative data for properties 3 and 4, it is recommended that the
measurement of reference values be repeated on four new specimens which are then used
