3.1
full scale test
test of a full size doorset/openable window in accordance with EN 1191
4 Determination of the field of extended application
4.1 General
4.1.1 Before there can be any consideration for extended application, the doorset/openable window
shall have been tested in accordance with EN 1191 to achieve a test result which could generate a
classification in accordance with EN 13501-2 or correspond to a use category according to EN 16034.
4.1.2 A review of the doorset/openable window construction parameters can indicate that one or more
characteristics can be improved by a particular parameter variation. All evaluations shall be made on the
basis of retaining the classifications obtainable from testing to EN 1191, including those with a lower
number of opening and closing cycles. However, this shall never lead to an increased classification for
any specific parameter beyond that achieved by testing, unless specifically identified in the relevant
Construction Parameter Variation tables.
4.1.3 If, when following the extended application procedure, any part of the classified product cannot
be covered by the extended application rules, that part shall be omitted from the subsequent extended
application report and classification report.
4.2 Procedure for evaluation
4.2.1 Identify the variations from the original test specimen(s) which are required to be covered by an
extended application report.
4.2.2 Locate the variations in the appropriate parameter variation by reference to columns (1) and (2)
of Annex A, Table A.1.
4.2.3 Establish from the contents of column (3) of Annex A, Table A.1 whether any extended application
is available without the need for further testing.
4.2.4 Where this is deemed to be possible, this can be recorded in the extended application report,
together with any appropriate restrictions and the stated rules from column (3) in Annex A, Table A.1.
4.2.5 Where the variations required can only be achieved from additional testing according to column
(4), the additional test can be made on a similar specimen type to the original test against which the
extended application is sought. Alternatively, column (4) in Annex A, Table A.1 identifies an option for
alternative testing and relevant test parameters.
4.3 Procedure for maximum field of extended application
4.3.1 It is possible to provide a limited field of extended application from the results of a single test.
However, where a manufacturer intends to produce a range of doorsets and openable windows
incorporating single leaf door assemblies and also double leaf door assemblies with or without glazing,
with alternative items of building hardware, etc., it is recommended that careful consideration is given to
the complete range of doorset designs and openable window designs and options in order to minimize
the testing required before testing commences.
4.3.2 Establish all the parameter variations which are required to be part of the product range.

SIST EN 17020-4:2021
EN 17020-4:2021 (E)
4.3.3 Determine which are the most important specification requirements and incorporate as many as
possible into the specimen(s) for the first tests in the series.
4.3.4 Conduct the first durability test or a series of tests and then establish which of the original desired
parameter variations have not been covered by this test(s).
4.3.5 Identify these parameter variations in Annex A, Table A.1 and establish if any extended
application is possible without further testing.
4.3.6 Record this for the extended application report together with any restrictions and rules given in
column (3) in Annex A, Table A.1.
4.3.7 Evaluate which, if any, of the desired parameter variations have not been covered by the initial
field of extended application derived from 4.3.6 above.
4.3.8 Determine if the product range is to include only single leaf doorsets or if the range is also to
include double leaf configurations. Where only single leaf doorsets are to be part of the product range,
the outstanding construction parameter variations shall only be incorporated into specimens for the
single leaf doorsets. Where single leaf and double leaf doorsets are to be included in the product range,
the outstanding construction parameter variations for the extended application of single leaf doorsets
may be incorporated into either repeated single leaf doorset tests or, in the weakest option, as defined in
column (4) of the table in Annex A, Table A.1, double leaf doorset configurations.
4.3.9 Select the required outstanding parameter variations from column (1) and column (2) of Annex A,
Table A.1 and observe from column (4) in Annex A, Table A.1 which are the most appropriate weakest
specimen options for further testing.
4.3.10 If the complete selection of required parameter variations has not been covered by the tests
completed in accordance with 4.3.8 and 4.3.9 above, then an appropriate test or tests may be carried out
with the additional product variations incorporated.
4.4 Interpretation of test results
4.4.1 In order to maximize the extended field of application, it is important that the test reports shall
record details of any failures occurred throughout the test duration.
4.4.2 Where a series of tests have been conducted, the field of extended application shall be based on
the lowest performance achieved from the complete series of tests, unless premature failure has been
attributed to one or more specific construction parameter variations.
4.4.3 Where it has been possible to identify specific parameter failures, the extended application for all
other construction parameter variations can be based on the performance achieved after isolating the
premature failure(s).
5 Extended application report
Prepare an extended application report in accordance with the requirements of EN 15269-1, based on
the results of evaluations in accordance with the above.
6 Classification report
The classification report shall be determined from the results of the extended application report and shall
be presented in accordance with EN 13501-2:2016, Annex A.

Annex A
(normative)

Construction parameter variations
Table A.1 below is designed to be used by experts competent in the field of fire and smoke resistance and
durability of self-closing testing of hinged and pivoted metal framed glazed doorsets and openable
windows.
This table shall only be used to assess a field of extended application when at least one positive durability
of self-closing test according to EN 1191 has generated a classification according to EN 13501-2 and
EN 16034.
The first two columns identify possible variations to the construction details of the specimen tested. It is
presupposed that the variations do not restrain the door/window closing.
Column (3) leads to the judgement of the possibility of extending the field of application.
Where additional tests are deemed to be necessary, the type of specimen approved for incorporation of
the changed parameter is defined in column (4). Where it is possible to use information from tests
performed on one configuration for evidence on a different configuration, this allowance has been made
in order to reduce the overall number of tests required for extended application evaluation e.g. single
action doorsets to double action doorsets.
Where an additional test is required in column (4), the test is a full scale test, unless otherwise specified.
In order to maximize the possible field of application from a minimum number of tests, the parameter
changes have been spread over a series of test specimens. Where more than a single parameter variation
is required, the influence on other variations shall also be taken into account.
All the rules in Table A.1, with exception are applicable to doorsets and openable windows. However, in
the text only the word “doorset” is used. The word “doorset” can be replaced by “openable windows” in
every rule.
NOTE Column (1) contains titles that are identical to the ones of EN 15269-5:2014+A1:2016, Table A.1,
without reference to possible figures. For clarification the figures that are included in EN 15269-5:2014+A1:2016,
Annex A can be used.

4 Determination of the field of extended application
4.1 General
4.1.1 Before there can be any consideration for extended application, the doorset/openable window
shall have been tested with EN 1191 to achieve a test result which could generate a classification in
accordance with EN 13501-2 and EN 16034.
4.1.2 A review of the doorset/openable window construction parameters can indicate that one or
more characteristics may be improved by a particular parameter variation. All evaluations shall be
made on the basis of retaining the classifications obtainable from testing to EN 1191, including those
with a lower number of opening and closing cycles. However, this shall never lead to an increased
classification for any specific parameter beyond that achieved by testing, unless specifically identified in
the relevant Construction Parameter Variation tables.

4.1.3 If, when following the extended application procedure, any part of the classified product cannot
be covered by the extended application rules, that part shall be omitted from the subsequent extended
application report and classification report.
4.2 Procedure for evaluation
4.2.1 Identify the variations from the original test specimen(s) which are required to be covered by
an extended application report.
4.2.2 Locate the variations in the appropriate parameter variation by reference to columns (1) and
(2) of Annex A, Table A.1.
4.2.3 Establish from the contents of column (3) of Annex A, Table A.1 whether any extended
application is available without the need for further testing.
4.2.4 Where this is deemed to be possible, this can be recorded in the extended application report,
together with any appropriate restrictions and the stated rules from column (3) in Annex A, Table A.1.
4.2.5 Where the variations required can only be achieved from additional testing according to column
(4), the additional test can be made on a similar specimen type to the original test against which the
extended application is sought. Alternatively, column (4) in Annex A, Table A.1 identifies an option for
alternative testing and relevant test parameters.
4.3 Procedure for maximum field of extended application
4.3.1 It is possible to provide a limited field of extended application from the results of a single test.
However, where a manufacturer intends to produce a range of doorsets and openable windows
incorporating single doors and also double doors with or without glazing, with alternative elements of
building hardware, etc., it is recommended that careful consideration is given to the complete range of
doorset designs and openable window designs and options in order to minimize the testing required
before testing commences.
4.3.2 Establish all the parameter variations which are required to be part of the product range.
4.3.3 Determine which are the most important specification requirements and incorporate as many
as possible into the specimen(s) for the first tests in the series.
4.3.4 Conduct the first durability test or a series of tests and then establish which of the original
desired parameter variations have not been covered by this test(s).
4.3.5 Identify these parameter variations in Annex A, Table A.1 and establish if any extended
application is possible without further testing.
4.3.6 Record this for the extended application report together with any restrictions and rules given in
column (3) in Annex A, Table A.1.
4.3.7 Evaluate which, if any, of the desired parameter variations have not been covered by the initial
field of extended application derived from 4.3.6 above.
4.3.8 Determine if the product range is to include only single leaf doorsets or if the range is also to
include double leaf configurations. Where only single doorsets are to be part of the product range, the
outstanding construction parameter variations shall only be incorporated into specimens for the single
leaf doorsets. Where single leaf and double leaf doorsets are to be included in the product range, the
outstanding construction parameter variations for the extended application of single leaf doorsets may
7

---------------------- Page: 9 ----------------------
oSIST prEN 17020-4:2020
prEN 17020-4:2020 (E)
be incorporated into either repeated single leaf doorset tests or, in the weakest option, as defined in
column (4) of the table in Annex A, Table A.1, double leaf doorset configurations.
4.3.9 Select the required outstanding parameter variations from column (1) and column (2) of
Annex A, Table A.1 and observe from column (4) in Annex A, Table A.1 which are the most appropriate
weakest specimen options for further testing.
4.3.10 If the complete selection of required parameter variations has not been covered by the tests
completed in accordance with 4.3.8 and 4.3.9 above, then an appropriate test or tests may be carried
out with the additional product variations incorporated.
4.4 Interpretation of test results
4.4.1 In order to maximize the extended field of application, it is important that the test reports shall
record details of any failures occurred throughout the test duration.
4.4.2 Where a series of tests have been conducted, the field of extended application shall be based on
the lowest performance achieved from the complete series of tests, unless premature failure has been
attributed to one or more specific construction parameter variations.
4.4.3 Where it has been possible to identify specific parameter failures, the extended application for
all other construction parameter variations can be based on the performance achieved after isolating
the premature failure(s).
5 Extended application report
Prepare an extended application report in accordance with the requirements of EN 15269-1, based on
the results of evaluations in accordance with the above.
6 Classification report
The classification report shall be determined from the results of the extended application report and
shall be presented in accordance with EN 13501-2:2016, Annex A.

Annex A
(normative)

Construction parameter variations
Table A.1 below is designed to be used by experts competent in the field of fire and smoke resistance
and self-closing durability testing of hinged and pivoted metal framed glazed doorsets and openable
windows.
The table shall only be used to assess a field of extended application when at least one positive self-
closing durability test according to EN 1191 has generated a classification according to EN 13501-2 and
EN 16034.
The first two columns identify possible variations to the construction details of the specimen tested. It is
presupposed that the variation does not restrain the door/window closing.
Column (3) leads to the judgement of the possibility of extending the field of application.
Where additional tests are deemed to be necessary, the type of specimen approved for incorporation of
the changed parameter is defined in column (4). Where it is possible to use information from tests
performed on one configuration for evidence on a different configuration, this allowance has been made
in order to reduce the overall number of tests required for extended application evaluation e.g. single
action doorsets to double action doorsets.
Where an additional test is required in column (4), the test is a full scale test, unless otherwise specified.
In order to maximize the possible field of application from a minimum number of tests, the parameter
changes have been spread over a series of test specimens. Where more than a single parameter
variation is required, the influence on other variations shall also be taken into account.
All the rules in Table A.1, with exception are applicable to doorsets and openable windows. However, in
the text only the word “doorset” is used. The word “doorset” can be replaced by “openable windows” in
every rule.
NOTE Column (1) contains titles that are identical to the ones of EN 15269–5:2014+A1:2016, Table A.1,
without reference to possible figures. For clarification the figures that are included in EN 15269–5:2014+A1:2016,
Annex A may be used.
