DIN EN 15725:2012-05 EN 15725:2010 + AC:2012 (E) 4 Introduction A construction product and a building element may be placed on
22、 the market with different thicknesses, densities, fixing conditions, substrates, etc. It is not practicable to test all combinations of different product parameters for the reaction to fire performance or fire resistance or external fire exposure performance, although these parameters may substanti
23、ally influence the test result. NOTE A building element is understood to be a defined construction component, e.g. wall, partition, floor, roof, beam or column. Fire test methods may not include any information on direct application, the result obtained in the test is that which is reported. In a se
24、parate exercise it is possible to extend the field of application of the individual test results to a variation of the values of the different product parameters. This process of extended application uses rules which are essentially based on a worst case scenario and interpolation techniques. All in
25、formation on extended field of application of reaction to fire results is given in CEN/TS 15117. There are a number of practical limitations on the size and design of elements that can be tested by the standard methods of test for fire resistance. When these elements are larger, or are of a modified
26、 design, there is a necessity to be able to confirm their performance, i.e. whether the classification(s) given in the classification report in relation to the relevant criteria are maintained, without the ability of being able to test them. To achieve this, extended application standards for the va
27、rious elements are under development. Rules for extended application of results from external fire exposure to roof tests are also under development. DIN EN 15725:2012-05 EN 15725:2010 + AC:2012 (E) 5 1 Scope This European Standard gives the procedures for preparing reports on the extended applicati
28、on process using the results of reaction to fire tests, fire resistance tests and external fire exposure to roof tests undertaken for fire classification of products and product families in accordance with the various parts of EN 13501. This standard makes reference to extended application standards
29、 throughout; wherever this term is used it refers to either a standard prepared by CEN/TC 127 Fire safety in buildings or the relevant product standard which includes information on extended application. In some cases, where a standard is not yet published, relevant bodies may issue recommendations
30、for use by Notified Bodies in attestation procedures for CE marking under the Construction Products Directive (CPD), http:/ec.europa.eu/enterprise/newapproach/nando/. The European system currently permits extended application rules to be included in technical specifications. CEN Technical Committees
31、 and EOTA Working groups producing these rules are asked to seek the guidance of CEN/TC 127 to ensure that their rules comply with standards prepared by CEN/TC 127. In cases where extended application rules in harmonised EN product standards and ETAs do not comply with standards prepared by CEN/TC 1
32、27 the CEN BT should be informed. 2 Normative references The following referenced documents are indispensable for the application of this document.

38、 of one test, or a set of tests, or from a process of extended application, are compared with limiting values for those parameters that are set as criteria for achieving a certain classification NOTE The relevant classes and related criteria are specified in the following Commission Decisions: a) Re
39、sistance to fire: 1) EC Decision 2000/367/EC (OJEU L 133 of 6.6.2000) as amended by EC Decision 2003/629/EC (OJEU L 218 of 30.8.2003); b) Reaction to fire: 1) EC Decision 2000/147/EC (OJEU L 50 of 23.2.2000) as amended by EC Decision 2003/632/EC (OJEU L 220 of 3.9.2003) and by EC Decision 2006/751/E
40、C (OJEU L 305 of 4.11.2006); c) External fire performance for roofs: 1) EC Decision 2001/671/EC (OJUE L 235 of 4.9.2001) as amended by EC Decision 2005/823/EC (OJEU L 307 of 25.11.2005). 3.2 product material, element or component about which information is required EN 13501-1:2007+A1:2009 3.3 produc
41、t family range of products within defined limits of variability (defined by the manufacturer or a technical specification) of the product parameters and, if relevant, end use parameters, for which the fire performance remains unchanged (i.e. does not get worse) 3.4 product parameter aspect of a prod
42、uct (for example thickness, composition, density) which may vary and which may or may not have an influence on the products fire performance 3.5 end use application where in the building the product is to be used, e.g. wall lining, flooring 3.6 end use condition way the product is incorporated into
43、the building, e.g. jointing, fixing and position with respect to adjacent products NOTE The mounting and fixing conditions for testing reflect the end use conditions. 3.7 test result outcome of a testing process and its associated procedures detailed within a specific test standard (which may includ

46、n procedures) that predicts, for a variation of a product property and/or its intended end use application(s), a test result on the basis of one or more test results to the same test standard 3.10 extended application report document reporting extended application results, including all details of t

48、 opinion results of a dialogue between a group of experts who are accepted by their peers as being knowledgeable in a particular fire test and the performance of products in that test. Such dialogue shall take place within a recognised and properly constituted forum, such as CEN/TC 127. These agreed expert opinions are then transformed into rules that may form the basis of extended application. Agreed expert opinion will lead notified bodies to a classification, suitable for the application of CE-marking. 3.13 e
