BS EN 15882-1:2011 EN 15882-1:2011 (E) 4 Introduction There are a number of practical li
21、mitations on the size and design of elements that 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 classif
22、ication report in relation to the relevant criteria 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
23、duct construction. If this is done outside the DiAP1)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-
24、1 to achieve a test result which could generate a 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 re
25、ports on the same proprietary construction of duct. 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 pe
26、riod for any specific parameter beyond that achieved during any one test. 1)DiAP = Direct field of application. 2)EXAP = Extended field of application. BS EN 15882-1:2011 EN 15882-1:2011 (E) 5 1 Scope This European Standard identifies parameters that affect the fire resistance of ducts for ventilati
27、on 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 contemplating the fire resistance on an untested variation in the construction. This European Standard, where applicable, give
28、s 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 parameters/constructional details relating to the relevant criteria (E, I, S) can be achieved. This European Standard onl
29、y 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 Standard. It does not cover ducts used for smoke control which are tested in accordance with EN 1366-8 or EN 1366-9. 2

46、ion product, the parameters listed in Clause 4 relating to ducts shall be considered in turn and their relevance shall be identified. This can normally be achieved in a tabular manner with using “yes” to identify those parameters that are relevant, and “no” to identify those that are not. For each r
47、elevant parameter the appropriate factors from those given in Clause 4 shall be analysed to establish their influence (positive or negative) on the fire resistance of the duct. In this case, the influence shall be established for integrity and insulation in turn and where appropriate smoke leakage.
48、The analysis shall take the form of considering influence of the proposed variation against: a) The application of the requirements in this European Standard; b) The use of calculations and rules defined in EN 1366-1 or in EN 15882-1. For each factor this analysis shall be transparent and the report
49、 shall include the justification.
