1 Scope This European Standard covers hinged or pivoted doorsets with timber based leaves, timber framed glazed doors and openable timber framed windows. It prescribes the methodology for extending the application of test results obtained from fire resistance test(s) conducted in accordance with EN 1634-1. This standard covers doorsets with internal structural elements which are comprised of timber. Subject to the completion of the appropriate test or tests, the extended application may cover all or some of the following examples:  integrity (E), integrity/radiation (EW) or integrity/insulation (EI1 or EI2) classification;  glazed elements including vision panels and framed glazed doorsets,
 louvres and/or vents;  side, transom or overpanels;  items of building hardware;  decorative finishes;  intumescent, smoke, draught or acoustic seals;  alternative supporting construction(s). The effect on the Classification ‘C’ for the doorsets following an extended application process is not addressed in this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

4.1 General 4.1.1 Before there can be any consideration for extended application, a representative doorset shall 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. 4.1.2 A review of the doorset 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. 4.1.3 If, when following the extended application procedure, any part of the classified product cannot be covered by the extended application rules then that part shall be omitted from the subsequent extended application report and classification report. 4.2 How to use the extended application rules in Annex A
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 Annex A. 4.2.3 Review the type of classification to be retained from column (3) of Annex A and establish from the contents of column (4) of Annex A whether any extended application is available beyond the direct application rules in EN 1634-1 without the need for further testing. 4.2.4 Where this is deemed to be possible, it can be recorded in the extended application report together with any appropriate restrictions and the stated rules from column (4) of Annex A. 4.2.5 Where the variations required can only be achieved from additional testing, the additional test can be made on a similar specimen type i.e. a doorset of the same or more onerous configuration where the leaf construction is fundamentally the same as that tested. Alternatively, column (5) of Annex A 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 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. This helps 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 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 fire resistance test or a series of tests and then establish which of the original desired parameter variations have not been covered by the fire resistance tests, including direct application possibilities. SIST EN 15269-3:2012

4.3.9 Select the required outstanding parameter variations from column (1) and column (2) of Annex A and observe from column (5) in Annex A 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 repeated with the additional product variations incorporated. 4.4 Analysis 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 premature integrity and/or insulation failure, as well as details of any significant distortion.
4.4.2 Where a series of tests forms the basis for the extended application, 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. 4.4.3 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).
5 Extended application report Prepare an extended application report in accordance with the requirements of Clause 6 of EN 15269-1:2010, 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.

Construction parameter variations This table is designed to be used by experts competent in the field of fire resistance testing of hinged or pivoted doorsets with timber based leaves. This table shall only be used to assess a field of extended application when at least one positive fire resistance test to EN 1634-1 has generated a classification according to EN 13501-2.
The first two columns identify possible variations to the construction details of the specimen tested. The influence of variation on performance characteristic is identified in column 3 as, integrity, insulation or radiation (E, I or W respectively). For some parameters, it is necessary to evaluate whether the specimen displayed a high, medium or low level of distortion during the test. Where this is the case, the following levels shall be used to establish high, medium and low distortion doorsets as measured using the maximum relative movement at any position between the edge of the door leaf and door frame or between the meeting edges of door leaves or the relative movement of the framing members for panelled systems. The measurements shall be taken from the start of the test at any time during the complete required classification period. The deflections shall be measured at the positions given in EN 1634-1:  Low: < 40 % of effective rebate depth;  Medium: ≥ 40 % and ≤ 85 % of effective rebate depth;  High: > 85 % of effective rebate depth. The effect of the change in each parameter is evaluated for each characteristic in column 3 under E for effects under I for integrity, for effects on insulation (whether I1 or I2) and under W for the effects on radiation. 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. In certain cases in column 4, it is a requirement to achieve Category B; the requirements for this are given in EN 1634-1. Where additional tests are deemed to be necessary, the type of specimen approved for incorporation of the changed parameter is defined in column 5. 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 order to maximize the possible field of extended 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 are dependant on the classification required and the preferred options. Solid timber can be replaced by other solid timber of the same group of equal or higher density or solid timber of a higher group, where Group 4 in Table A.1 is the highest group.
