European foreword
This document (prEN 17020-2:2016) has been prepared by Technical Committee CEN/TC 33 “Doors,
windows, shutters, building hardware and curtain walling”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
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 12605 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.
1 Scope
This European Standard covers steel rolling shutters as covered by EN 15269-10.
This document prescribes the methodology for extending the application of test results obtained from
durability self-closing test(s) conducted in accordance with EN 1634-1.
Subject to the completion of the appropriate self-closing test or tests, the extended application may
cover all or some of the following non-exhaustive list:
— Integrity only (E), radiation (EW) or insulated (EI1 or EI2) classifications;
— shutter curtain;
— wall/ceiling fixed elements (frame/suspension system);
— decorative finishes;
— intumescent, smoke, draught or acoustic seals;
— alternative supporting construction(s).

For the purposes of this document, the terms and definitions given in EN 1363-1, EN 1363-2,
EN 1634-1, EN 15269-1, EN 12433-1, EN 12433-2 and EN ISO 13943 and the following apply.
3.1
full scale test
test of a full size doorset or rolling shutter in accordance with EN 12605
4 Determination of the field of extended application
4.1 General
4.1.1 Before there can be any consideration for extended application the steel rolling shutter
assemblies shall have been tested and classified in accordance with EN 12605 and EN 13501-2
respectively in order to establish a classification for the doorset.
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 obtainable from testing to EN 12605, 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 All evaluations shall be made on the basis of retaining the classification obtained from testing to
EN 1634-1 or EN 1634-3 and EN 12605.
4.1.4 If, by 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 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 (4) 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 (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) 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 steel rolling shutters assemblies
incorporating manual and power 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 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 Select the required outstandin
