Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsib
17、le for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland,

BS EN 15725:2010 EN 15725:2010 (E)4 Introduction A construction product and a building e
19、lement may be placed on 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 p
20、arameters may substantially 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 whi
21、ch is reported. In a separate 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 interpola
22、tion techniques. All information 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 large
23、r, or are of a modified 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 applicati
24、on standards for the various elements are under development. Rules for extended application of results from external fire exposure to roof tests are also under development. BS EN 15725:2010 EN 15725:2010 (E)5 1 Scope This European Standard gives the procedures for preparing reports on the extended a
25、pplication 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 s
26、tandards 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 recommen
27、dations 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 Co
28、mmittees 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
29、CEN/TC 127 the CEN BT should be informed. 2 Normative references The following referenced documents are indispensable for the application of this document.

34、under the Construction Products Directive 3 Terms and definitions For the purposes of this document, the following terms and definitions apply: BS EN 15725:2010 EN 15725:2010 (E)6 3.1 classification process defined in EN 13501, whereby the fire performance parameters obtained from the results of one
35、 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) Resistanc
36、e 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/EC (OJEU
37、 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 product famil
38、y 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 product (fo
39、r 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 the bui
40、lding, 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 include some
41、processing of the results from the testing of a number of specimens) and expressed in terms of one or more fire performance parameter(s) BS EN 15725:2010 EN 15725:2010 (E)7 3.8 direct field of application of test results outcome of a process (involving the application of defined rules) whereby a tes
42、t result is deemed to be equally valid for variations in one or more of the product properties and/or intended end use applications 3.9 extended field of application of test results outcome of a process (involving the application of defined rules that may incorporate calculation procedures) that pre
43、dicts, 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 the process leading to
44、those results 3.11 calculation method that can be applied to one or more parameters of a result of a test which is based on existing physical laws or which has been empirically validated and which forms part of the process of defining the extended application 3.12 agreed expert opinion results of a
45、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 t
46、hen 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 expert judgement view of a recognised expert in a particular fire test, and performance of products in tha
47、t test, that may be used for the purpose of interpreting or applying results of that test in connection with the application of the particular product into parts of works for the purposes of satisfaction of national regulations NOTE Expert judgement cannot form any part of extended application for C
48、E marking, but may be obtained by manufacturers as a voluntary judgement outside of CE-marking. 3.14 constructional parameter design and construction that may be varied and which may result in a change in the fire resistance performance, e.g. in a stud framed separating element a change in the dimen
49、sions of a stud 3.15 thermal and mechanical parameters conditions of a test that may influence the classification given, e.g. the pressure differential that will exist at the top of a larger element than existed at the top of the specimen when tested 3.16 factor variation that may be applied to a parameter, e.g. a change in the stiffness as a result of a dimensional change in the stud BS EN 15725:2010 EN 15725:2010 (E)8 3.17 factor influence potential cause of a change
