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 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.

full scale test
test of a full size rolling shutter assembly
Note 1 to entry: This test is in accordance with EN 12605:2000.
4 Determination of the field of extended application
4.1 General
4.1.1 Before there can be any consideration for extended application, the metal rolling shutter
assembly shall have been tested in accordance with 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 for the required
number of test cycles.
4.1.2 A review of the 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 for the durability of self-closing obtainable from testing to EN 12605:2000, 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 achieved by 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(es) not prevent the rolling shutter 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 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) of Table A.1, the additional test can be made on a similar test specimen type to the original
test against which the extended application is sought. Alternatively, column (4) 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 rolling shutter assemblies incorporating
manual and power operated drives, insulated and uninsulated version, with alternative elements of
construction etc. it is recommended that careful consideration is given to the complete range of 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 test specimen(s) for the first tests in the series.
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).
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 Select the required outstanding parameter variations from column (1) and column (2) of
Table A.1 and observe from column (4) of Table A.1 which are the most appropriate weakest test
specimen options for further testing.
4.3.9 If the complete selection of required parameter variations has not been covered by the tests
completed in accordance with 4.3.8 above, then an appropriate test or tests may be repeated with the
additional product variations incorporated.
4.4 Interpretation of test results
4.4.1 In order to maximize the field of extended application, it is important that the test reports shall
record details of any failures which 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 variation(s).
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). The failed parameter has to be omitted from the extended application report and
the subsequent classification 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 durability of self-closing
testing of metal rolling shutter assemblies.
The table shall only be used to assess a field of extended application when at least one positive durability
of self-closing test to EN 12605 has generated a classification according to EN 13501-2 for the required
number of test cycles.
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 rolling shutter assembly 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 test 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.
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 parameter variations in Table A.1 presuppose that the total weight of the curtain does not exceed the
maximum weight having been tested. If the durability of self-closing test is carried out with a test
specimen that has a lower curtain weight than the maximum weight required by the manufacturer (e.g.
due to size reasons), then the higher curtain weight shall be simulated in order to achieve the same
mechanical load in all load-bearing components that would result with the required maximum curtain
weight. For simulation of a higher weight of the varied curtain the test specimen for durability of self-
closing test can be loaded with additional weight(s) attached to the curtain according to the rules in
Annex B.
For standard parts (e.g. screws) or parts made exclusively of steel (e.g. barrel, support brackets) the
manufacturer may be changed as long as all characteristics of the part (e.g. material, geometry, welding
technique) remain the same and unless otherwise stated in Table A.1.
