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 a 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 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 will need to have been
tested in accordance with EN 1634-1 resp. EN 1634-3 and EN 1191 to achieve a test result which could
generate a classification in accordance with EN 13501-2 at least equal to the classification subsequently
required from extended application considerations.

apply.
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 and classified in accordance with EN 1191 and EN 13501-2 in order to establish a
classification for the doorset/openable window. Before the extended application process can be applied
on a construction parameter variation it shall be ensured that the varied doorset/openable window is
able to self-close without restraint at least once.
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 All evaluations shall be made on the basis of retaining the classification obtained from testing to
EN 1191.
4.1.4 When following the extended application procedure, any part of the classified product, which
cannot be covered by the extended application rules, 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 (4) of Table A.1 whether any extended application is
available without the need for further testing.

oSIST prEN 17020-4:2016
prEN 17020-4:2016 (E)
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 (4) in Table A.1.
4.2.5 Where the variations required can only be achieved from additional testing according to column
(5), the additional test can be made on a similar specimen type to the original test against which the
extended application is sought. Alternatively, column (5) 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 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 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 (4) 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 (5) 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 (5) 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 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.
4.4.2 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 15269-1:2010, Clause 6 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 13501-2:2007+A1:2009, 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.
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 (4) 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 (5). 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 (5), 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. The recommended tests for each parameter
is depending upon the classification required and the preferred direction of testing as indicated in
column (5).
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, Table A.1, without
reference to possible figures. For clarification the figures that are included in EN 15269–5:2014, Annex A may be
used.
