CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to
20、 CEN by the European Commission and the European Free Trade Association. This European Standard has the general title Extended application of results from fire resistance tests for service installations and consists of the following parts: - Part 1: Ducts; - Part 2: Dampers; - Part 3: Penetration se

24、can be tested by the standard methods of fire resistance test. When these elements are larger, or are of a modified design, there is a necessity to be able to confirm their performance, i.e. whether the classification(s) is (are) given in the classification report in relation to the relevant criteri
25、a identified in the Interpretative Document are maintained, without the ability of being able to test them. To achieve this, extended application documents for the various elements are under development. It is not allowed to change any detail of the duct construction. If this is done outside the DiA
26、P1)and EXAP2), the duct has another design and cannot be classified in accordance with EN 13501-3 without further appropriate testing. Before there can be any consideration for extended application the duct shall be tested in accordance with EN 1366-1 to achieve a test result which could generate a
27、classification in accordance with EN 13501-3 at least equal to the classification subsequently required from extended application considerations. The extended application report should be based on the evaluation of one or more fire resistance test reports on the same proprietary construction of duct
28、. A review of the duct construction parameters may indicate that one or more criteria (integrity, insulation, leakage) may be improved by a particular parameter variation. In the case of ducts, this should never lead to an increased classification period for any specific parameter beyond that achiev
29、ed during any one test. 1)DiAP = Direct field of application. 2)EXAP = Extended field of application.

30、1:2011 (E) 5 1 Scope This European Standard identifies parameters that affect the fire resistance of ducts for ventilation purposes. It also identifies the factors that need to be considered when deciding whether, or by how much a parameter can be extended either positively or negatively when contem
31、plating the fire resistance on an untested variation in the construction. This European Standard, where applicable, gives guidance on additional tests that are needed to extend the field of application. The European Standard gives the principles behind how a conclusion on the influence of specific p
32、arameters/constructional details relating to the relevant criteria (E, I, S) can be achieved. This European Standard only applies to ducts tested to EN 1366-1. Duct sections for use other than in fire resisting heating, ventilation and air conditioning (HVAC) systems are not covered by this European
33、 Standard. It does not cover ducts used for smoke control which are tested in accordance with EN 1366-8 or EN 1366-9. 2 Normative references The following referenced documents are indispensable for the application of this document.
