EN 15269-11:2018+AC:2019 (E) 6 Introduction This European Standard 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 fire resistance and/or smoke control tests. These 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 should have been tested in accordance with EN 1634-1 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. A review of the door assembly construction parameters can indicate that one or more characteristics may be improved by a particular parameter variation. All evaluations should be made on the basis of retaining the fire resistance classifications obtainable from testing to EN 1634-1, including those lower than the test duration. However, this should never lead to an increased classification for any specific fire resistance and/or smoke control performance parameter beyond that achieved during any one test unless specifically identified in the relevant Construction Parameter Variation tables within this series of standards. The effect on the maintaining of the self closing function (C-classification) of the door assemblies following an extended application process is not addressed in this series of standards.

EN 15269-11:2018+AC:2019 (E) 7 1 Scope This document covers vertically mounted types of manual or powered, operable fabric curtain assemblies with downward closing operation. Curtain systems are different from (are separated from) door systems due to their not rigid closure element typically made of thin walled materials as for instance woven or knitted fabrics and foils. These closure elements are not able to carry significant loads normal to their surface by their bending stiffness. In other words: curtain systems are separated from door systems because they can only conduct pulling forces by tensile stress in plane to their surface. Pushing forces are not conducted in plane to their surface. This document establishes the methodology for extending the application of test results obtained from test(s) conducted in accordance with the EN 1634-1 test method for shutters. Subject to the completion of the appropriate test or tests selected from those identified in Clause 4, the extended application may cover all or some of the following non-exhaustive list of examples: — uninsulated (E), radiation (EW) or insulated (EI1 or EI2) classifications; — coiling mechanisms; — wall/ceiling fixed elements; — items of building hardware; — decorative finishes; — intumescent, draught or acoustic seals; — alternative supporting construction(s). 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

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 1634-1, including those lower than the test duration. 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. All evaluations shall be made on the basis of retaining the classification obtained from testing to EN 1634-1. If, by following the ensuing procedure, any part of the classification cannot be achieved by extended application rules that part of classification shall be omitted from the subsequent extended application report and classification report. 4.2 Procedure for maximum field of extended application Identify the variations from the original test specimen(s) which are required to be covered by an extended application report - see Figure A.1 for a typical operable curtain. Locate the variations in the appropriate parameter variation by reference to columns (1) and (2) of Table A.1. Review the type of classification to be retained from column (3) of Table A.1 and establish from the contents of column (4) of Table A.1 whether any extended application is available without the need for further testing. SIST EN 15269-11:2018+AC:2019



EN 15269-11:2018+AC:2019 (E) 12 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. Where the variations required can only be achieved from additional testing according to column (5) in Table A.1, 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. ˜deleted text™ 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 operable fabric curtains, 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. Establish all the parameter variations which are required to be part of the product range. Select specimen(s) for the first test(s) in the series to ensure that the most important parameter variations for the manufactured products are covered. Complete the first test or a series of tests and prepare a field of direct application and possibly a classification report from the results of the test(s). Establish which of the original desired parameter variations have not been covered by the direct application and classification report. Identify these parameter variations in Annex A and establish if any extended application is possible without further testing. Record this for the extended application report together with any restrictions and rules given in column (5) in Table A.1. Evaluate which, if any, of the desired parameter variations have not been covered by the field of direct application or the initial field of extended application derived from ˜4.2, paragraph 12™ above. Select the required outstanding parameter variations from column (1) and column (2) of Table A.1 and observe from column (5) of Table A.1 which are the most appropriate weakest specimen options for further testing. If the complete selection of required parameter variations has not been covered by the tests completed in accordance with ˜4.2, paragraph 14™ above, then an appropriate test or tests may be repeated with the additional product variations incorporated. 4.3 Interpretation of test results In order to maximize the field of extended application, it is important that the test reports shall record details of any integrity and/or insulation failures throughout the test duration. 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. 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). 4.4 Additional measurements To use extended application the following measurements are to be taken: — Figure A.3 S = Shrinking allowance; SIST EN 15269-11:2018+AC:2019

Construction parameter variations for Fabric Curtain assemblies Table A.1 is designed to provide criteria for the creation of extended application reports by experts in the field of fire resistance testing of operable fabric curtain assemblies. Table A.1 shall only be used to evaluate a field of extended application when at least one positive fire resistance test to EN 1634-1 has resulted in a classification according to EN 13501-2. The first two columns identify possible variations to the construction details of the specimen tested. The type of classification achieved from the test can be identified from the ‘Performance characteristic’ section of Table A.1 column 3 as insulation, radiation control or integrity only.
