prEN 15269-1 together with the following apply : 3.1 core material fitted centrally within the thickness of a door leaf.

It may consist of a single sheet of material or a combination either of sheets of the same material or layers of different materials 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 and classified in accordance with EN 1634-3 and EN 13501-2 respectively in order to establish a classification for the doorset. 4.1.2 Evaluation to a higher classification is not possible. 4.1.3 All evaluations shall be made on the basis of retaining the classification obtained from testing to EN1634-3.

prEN 15269-20:2006 (E) 5 4.1.4 If, by following the ensuing procedure, any part of the classification cannot be achieved by extended application theory, that element of classification 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 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. 4.2.4 Where this is 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, the additional test can be made on another door from the same product family including the required variation against which the extended application is sought. Alternatively, column (5) in Table A.1 identifies an option for alternative testing and relevant test parameters. 4.2.6 It is a requirement of this document that all items of building hardware are in accordance with the relevant product standard and that the door assembly onto which the building hardware will be fitted is appropriate to that class of use.

4.3 Procedure for maximum field of extended application 4.3.1 It is possible to provide an extended field of application from a single test. However, where a manufacturer envisages to manufacture a range of doors incorporating single doors and also double doors with or without side, transom or over panels, with or without glazing, louvres or ventilation grilles, with alternative element of building hardware, etc., it is recommended that careful consideration is given to the complete range of doorset designs and options in order to minimise the testing required before testing commences. 4.3.2 Establish all the parameter variations which are required to be part of the product ‘family’, and in particular for single leaf hinged or pivoted timber based doorsets into rebated frames. 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 Complete the first test or a series of tests and prepare a field of direct application and a classification report from the results of the test(s). 4.3.5 Establish which of the original desired parameter variations have not been covered by the direct application classification report. 4.3.6 Identify these parameter variations using Table A.1 and establish where an extended application is possible with the available test evidence. 4.3.7 Record this for the extended application report together with any restrictions and rules given in column (5) in Table A.1. 4.3.8 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 4.3.6.

prEN 15269-20:2006 (E) 6 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 have not been covered by the tests completed in accordance with 4.3.8 and 4.3.9, 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 maximise the field of extended application, it is important that the test reports shall record details of any failure throughout the duration of the test.

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 excessive leakage has been attributed to one or more specific construction parameter variation. 4.4.3 Where it has been possible, to identify leakage due to a specific parameter, the extended application for all other construction parameter variations can be based on the performance achieved after isolating the parameter with excessive leakage. 5 Extended application report Prepare an extended application report in accordance with the requirements of Clause 5 of EXAP prEN 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 presented in accordance with EN 13501-2.

prEN 15269-20:2006 (E) 7 Annex A (normative)

Construction Parameter Variations A.1 General Table A.1 is designed to be used by competent experts in the field of smoke control testing of hinged or pivoted doorsets and shutter assemblies. Table A.1 shall only be used to evaluate a field of extended application when at least one positive smoke control test to EN 1634-3 has resulted in a classification according to EN 13501-2.

The first two columns of Table A.1 identify possible variations to the construction details of the specimen tested.

The type of classification, referred to as performance characteristic in Column 3 of Table A.1, achieved from the test can be identified as the ‘Type’ section of Table A.1 column 3 as Ambient Smoke Control (Sa) and Medium Temperature Smoke Control (Sm).

The effect of the change in each parameter is evaluated for each characteristic in Table A.1 column 3 under Sa for Ambient temperature and Sm for Medium temperature. Where symbols are used these relate to the following definitions : a) < - forecast is a worse performance; b) > - forecast is a better performance; c) ≤ - forecast is a worse or equal performance; d) ≥ - forecast is a better or equal performance; e) >=< - forecast unknown These evaluations lead to the judgement of the possibility of the extension of the field of application the results of which are given in column 4 of Table A.1.

Where additional tests are deemed to be necessary the type of specimen approved for incorporation of the changed parameter is defined in column 5 of Table A.1. 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). In all cases following the evaluation, the relationship between the leaf and the frame (e.g. gaps) shall remain the same as shall the relationship between smoke seals and the faces and/or edges of the leaf (i.e. the contact between the edges of the smoke seal and the leaf face) shall not decrease, nor shall the contact between the smoke seal and the leaf edge. Solid timber can be replaced by other solid timber of the same or higher density. Glued timber with solid pieces of min. 10 mm thickness may be used as solid timber. Composite wood products (e.g. Medium Density Fibreboard) may not be replaced with other materials or composites. Each construction parameter variation may only be applied in isolation from other variations. If after consideration of a specific variation, additional changes are required to be made to the specimen, these may be made providing the implications on other variations are also taken into account.
