BS EN 15882-2:2015EN 15882-2:2015 (E) 4 Introduction It should be noted that fire-resisting dampers are special products that are exposed to different conditions to other elements of construct
19、ion; in particular they are subjected to significantly different pressure regimes. Also, integrity is evaluated by leakage measurements. Consequently, this European Standard may adopt a different approach to other extended field of application standards, with more emphasis on testing. BS EN 15882-2:
20、2015EN 15882-2:2015 (E) 5 1 Scope This European Standard provides guidance and rules to notified bodies (for fire dampers) to allow them to produce/validate an extended field of application report for fire dampers. This standard identifies the parameters that affect the fire resistance of dampers. I
21、t also identifies the factors that need to be considered when deciding whether, or by how much, the parameter can be extended when contemplating the fire resistance performance of an untested, or untestable variation in the construction. This European Standard explains the principles behind how a co
22、nclusion on the influence of specific parameters/constructional details relating to the relevant criteria (E,I,S) can be achieved. This European Standard does not cover dampers used for smoke control. This European Standard only applies to extended fields of application based on tests successfully u
23、ndertaken to EN 1366-2. Only test reports that have a total test time where the criteria are fulfilled that is in excess of the required classification period by a margin of either 10 % or 12 min, whichever is the least, are to be considered. Each classification (E,I,S) is to be considered individua
24、lly consequently E (134 min achieved) may be extended, but EI (61 min achieved) may not be extended for a classification of EI60. Additionally, leakage determined during such tests is to be at least 10 % below the leakage limits for E, or for E-S, dependent on classification achieved, given in EN 13
25、501-3 before the EXAP rules can be applied. The 10 % below the leakage limits is to be fulfilled for the extended period in addition to the classification period. By application of this European Standard, it should be possible to identify what specifications should be tested to maximize the field of
26、 application. Some information on test programmes is given for guidance purposes. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

30、 this document, the terms and definitions given in EN 1363-1 and EN 1366-2 and the following apply. 3.1 multiple section assemblies assemblies of individual damper units to form larger units 3.2 horizontal orientation of damper position of the damper mounted horizontally EXAMPLE When installed in th
31、e plane of a floor or a ceiling. 3.3 vertical orientation of damper position of the damper mounted vertically, e.g. when installed in the plane of a wall 3.4 supporting construction construction used as part of the test assembly to support the test specimen and to fill in the furnace aperture 3.5 st
32、andard supporting construction supporting construction that has known fire behaviour and for which a Direct Field of Application has been established 4 Determination of worst case In certain circumstances a rule can call for a new test to be undertaken. To avoid having to re-test everything, a deter
33、mination shall be made of worst case. Firstly consider the classification required: E, EI, E-S, EI-S. Consider all the test reports that give the required classification. Determine which criteria failed first in each test. The resulting worst case will be the one where the time to failure of each an
34、d any of the parameters was the lowest. If the test periods show that none of the criteria failed before the classification period plus 10 % or 12 min, then the supporting construction shall be considered. The worst case shall be with the fire damper mounted in the lightest construction in terms of
35、mechanical stability. The sponsor may pick a heavier supporting construction, but then any extended field of applications shall only apply to this supporting construction and those heavier and more dense as per direct field of application. The method of determination of worst case and the related ex
36、tended fields of application shall be reported in the extended field of application report. 5 Conditions and application rules 5.1 Change of fixing damper to supporting construction a) No change in the location of the fixings relative to the damper and the supporting construction shall be permitted.
37、 The pitch between the fixings shall not be increased. BS EN 15882-2:2015EN 15882-2:2015 (E) 7 b) Alternative fixings may be used if their performance is proven by fire test, stress, linear expansion and loading information data. Any other information available may be considered. c) Any alternative
38、fixings shall be included as part of the extended field of application report. d) Hanger and relating anchor information shall be assessed in accordance with EN 15882-1. 5.2 Multiple damper assemblies 5.2.1 E Classification only 5.2.1.1 Method To allow the use of multiple assemblies of E classified
39、fire dampers, either side by side or on top of each other, the following test shall be performed. An assembly consisting of fire dampers that have already successfully gained a classification conforming to EN 13501-3 shall be made and installed into a supporting construction using the proposed metho
40、d. A fire damper selected using the worst case method in accordance with Clause 4 shall be made into an assembly as shown in Figure 1. This will allow the other EXAP rules from the tables which follow to apply to multi-section units, as they do to single section units. The unit to be tested shall be
41、 constructed so as to be made up of at least four sections and shall have a maximum overall size of 2 600 mm 2 600 mm. This is to allow for a small gap around the outside of the damper and a minimum span of supporting construction of 200 mm all round. See Figure 1 which is applicable to both vertica
42、l (shown) and horizontal test installations. The test method shall be generally as EN 1366-2 (note: also refer to intumescent fire damper test, if this becomes relevant), but instead of a closed plenum with a fan, an extended open duct 1 m long shall be fixed to the dampers. The plate thermometers f
43、or control of furnace temperature shall be placed at the centre of area of each fire damper section. Leakage shall not be measured. A 300 Pa differential pressure shall not be set across the unit. The criteria used shall be the integrity at all of the following: round the joint between the damper in
44、stallation and the supporting construction; any point within the damper assembly, (joints, blades, etc.); sustained flaming at any point around the perimeter or at the blades or joints. If the individual fire damper sections do not close within the first 90 s, provision shall be made to manually clo
45、se the sections after 2 min (air may be drawn into the bottom of the furnace having a cooling effect). Wire thermocouples shall be placed at each thermal sensing element for information purposes. This information shall be recorded. Classification will be as the original single section units with reg
46、ard to the E classification as long as the above integrity criteria are fulfilled. BS EN 15882-2:2015EN 15882-2:2015 (E) 8 5.2.1.2 Field of application If, due to the size restriction of 2 600 mm 2 600 mm, the assembly is made up of four individual units which are smaller than or of the same size as
47、 the original single unit tested, assemblies for application may be made of units up to the single unit size tested. EXAMPLE 1 An assembly of four units with an overall size of 2 600 mm 2 600 mm, made from individual units with overall size 1 300 mm 1 300 mm, representing a single section size teste
48、d of 1 500 mm 1 300 mm, allows an assembly of overall size 3 000 mm 2 600 mm to be used. If the assembly is made up of four or more units, leading to whatever overall size, the size of unit to be used shall have been tested previously as a single unit. For application, the units then used to make up
49、 assemblies shall not exceed the size of the units tested as part of the assembly. This test may not be used to allow larger units to be back assessed to single sections for classification to EN 13501-3: EXAMPLE 2 An assembly of 6 units of individual overall size 600 mm 600 mm, giving an assembly size of 1 200 mm 1 800 mm, allows the use of multiple assemblies of units of individual size 600 mm 600 mm. If the individual unit tested was 1 000 mm 1 000 mm, the use of this to build assemblies is not now permitted as this could have been ass
