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 shall have been tested
in accordance with EN 1191 and/or EN 12605:2000 to achieve a test result which could generate a
classification for the durability of self-closing in accordance with EN 13501-2 and / or correspond to a
use category according to EN 16034.
4.1.2 A review of the doorset 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 for the durability of self-closing obtainable from testing to EN 1191 and/or
EN 12605:2000, including those with a lower number of opening and closing cycles. However, this shall
never lead to an increased classification for the durability of self-closing for any specific parameter
beyond that achieved during any one test 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. Ensure that the variation(s) do/does not prevent the doorset from self-
closing.
4.2.2 Locate the variations in the appropriate parameter variation by reference to columns (1) and (2)
of Table A.1.
4.2.3 Establish from the contents of column (3) of Table A.1 whether any extended application is
available beyond the direct application rules in EN 1191 and/or EN 12605:2000 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 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 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 incorporating single leaf doorsets
and also double leaf doorsets 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 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.
9
---------------------- Page: 11 ----------------------
SIST EN 17020-5:2023
EN 17020-5:2023 (E)
4.3.4 Conduct the first durability of self-closing test or a series of tests and then establish which of the
original desired parameter variations have not been covered by this test(s), including direct application
possibilities.
4.3.5 Identify these parameter variations in 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 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 to also
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 Table A.1, double leaf doorset configurations.
4.3.9 Select the required outstanding parameter variations from column (1) and column (2) of
Table A.1 and observe from column (4) in 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). This means that the failed parameters have to be excluded from the classification /
EXAP report.
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.

Annex A
(normative)
Construction parameter variations
Table A.1 below is designed to be used by experts competent in the field of fire resistance and smoke
control and durability of self-closing testing of hinged or pivoted doorsets with timber based door leaves.
This table shall only be used to assess a field of extended application when at least one positive durability
of self-closing test to EN 1191 and/or EN 12605:2000, as appropriate has generated a classification
according to EN 13501-2 and /or correspond to a use category according to 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 doorset from 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 extended 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.
Construction parameters tested on the inactive door leaf of a double leaf doorset can only be transferred
to the active door leaf, when both door leaves have been tested with the same number of cycles.
Solid timber can be replaced by any other solid timber of equal or higher density.

Introduction
The EN 15269 series of standards covering extended application of test results for fire resistance and/or
smoke control for door, shutter and openable window assemblies, including their elements of building
hardware, does not include the durability of self-closing of the doorsets following an extended application
process. This document is one of the EN 17020 series of standards intended to be used for the purpose of
producing an extended application report based on the evaluation of one or more durability of self-
closing tests. These European Standards may also be used to identify the best selection of test specimens
required to cover a wide range of product variations.
Before there can be any consideration for extended application, the doorset 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 at least equal to the classification
subsequently required from extended application considerations.

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 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 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 during any one test 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 Table A.1.
4.2.3 Establish from the contents of column (3) of 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 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 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 doors 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 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 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 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 to also
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
be incorporated into either repeated single leaf doorset tests or, in the weakest option, as defined in
column (4) of the table in Table A.1, double leaf doorset configurations.

---------------------- Page: 10 ----------------------
oSIST prEN 17020-5:2021
prEN 17020-5:2021 (E)
4.3.9 Select the required outstanding parameter variations from column (1) and column (2) of
Table A.1 and observe from column (4) in 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 or pivoted doorsets with timber based leaves.
This table shall only be used to assess a field of extended application when at least one positive self-
closing durability test 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 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 extended 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.
Solid timber can be replaced by other solid timber of the same group of equal or higher density or solid
timber of a higher group, where Group 4 in Table 1 is the highest group.
