Plastics - Acquisition and presentation of comparable multipoint data - Part 3: Environmental influences on properties (ISO 11403-3:2014)
EN ISO 11403-3 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.

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.

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.

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.

---------------------- Page: 15 ----------------------
SIST EN ISO 11403-3:2014
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). 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 to
B
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/min ± 10 mm/min
B
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

each indicative property at each temperature and a minimum of four temperatures for determining the
profile for each property (see the note).
NOTE Some of the exposure times may yield results that can be used for the determination of both of the
property profiles.

ISO/FDIS 11403-3:2014(E)IntroductionThis International Standard has been prepared because users of plastics
Ðind sometimes that available data cannot be used readily to compare the properties of similar materialsá especially when the data have been supplied by different sourcesä Even when the same standard tests have been usedá they often allow the adoption of a wide range of alternative test conditions, and the data obtained are not necessarily comparableä The purpose of this International Standard is to identify speci Ðic methods and conditions of test to be used for the acquisition and presentation of data in order that valid comparisons between materials can be madeä These data are not necessarily suitable for designäISO 10350[4][5] 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 selectionä The present International Standard identi Ðies test conditions and procedures for the measurement and presentation of a more substantial quantity of dataä Each property here is characterized by multipoint data which demonstrate how that property depends upon important variables such as timeá temperature and environmental effects. Additional properties are also considered in this standard. These data therefore enable more discriminating decisions to be made regarding the materialïs suitability for a particular applicationä Some data are also considered adequate for undertaking predictions of performance in service and of optimum processing conditions for moulding a componentá although it should be recognized thatá 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 materialä The test procedures referred to in this standard employ standard test specimensá and the polymer structure in these specimens may be signi Ðicantly different from that in speci Ðic regions of a moulded componentä Under these circumstancesá therefore, the data will not be suitable for accurate design calculations for product performance. The material supplier should be consulted for speci Ðic information on the applicability of dataäISO
s r u w r and the various parts of this International Standard together de Ðine 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 dataä Furthermoreá reference to these standards will simplify the development of data models for the computerized storage and exchange of data concerning material propertiesäWhere appropriateá values for test variables have been speci Ðied by this standardä 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 polymerä Becauseá in generalá the properties and performance speci Ðications for different polymers differ widelyá there is no obligation to generate data under all the test conditions speci Ðied in this standardäData 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 suitedä ISO standards describe experimental procedures which are suitable for the acquisition of relevant information on many of these propertiesä For other propertiesá 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 independentlyä In this wayá additional properties can be included as new or revised standards become available. vi © ISO 2014 – All rights reservedkSIST FprEN ISO 11403-3:2014

¹C before and after speci Ðied conditions of exposureä The tensile strength and the tensile work to break are indicative properties that are common to each of the environmental exposure testsä The tensile strength is either the yield stress Y or, for brittle materials, the stress at break B minimum initial cross-sectional area of the specimen in the waisted region. The tensile work to break WtB (see 3.4) is determined from a conventional tensile test used to obtain the tensile strength and is normalized with respect to the minimum initial crossæsectional area of the specimenä In this part of ISO 11403, all indicative data are recorded as a ratio of a measurement after exposure to a measurement prior to exposureä 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 propertyä6.3 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 1y be usedä 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
