4 Determination of the field of extended application 4.1 General Before there can be any consideration for extended application the operable fabric curtain shall have been tested and classified in accordance with EN 1634-1 and EN 13501-2 respectively in order to establish a classification for the operable fabric curtain. 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 pa rameter 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.
4.3 Procedure for maximum field of extended application 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.BS EN 15269-11 pdf download.
