BS EN 1366-12:2014EN 1366-12:2014 (E) 5 Introduction The purpose of the test is to evaluate the ability of a non-mechanical (no moving parts) fire barrier (see Annex A) t

26、o prevent fire and smoke spreading from one fire compartment to another through the air ductwork system which may penetrate fire separating walls and floors. Non-mechanical fire barriers are unable to achieve an “S” classification, which requires a known limited ambient leakage, as they are unable t

27、o be closed except under fire conditions. The non-mechanical fire barrier is attached (directly or remotely via a section of ducting), to a fire separating element in a manner representative of practice. Tests are performed starting with the non-mechanical fire barrier in its cold standard state to

28、expose it to furnace conditions. Temperature and integrity measurements are carried out in various parts of the test construction during the test. The leakage of the non-mechanical fire barrier system is measured (continuously during the test) by direct flow measurements while maintaining a constant

29、 pressure differential across the closed non-mechanical fire barrier of 300 Pa. Caution: The attention of all persons concerned with managing and carrying out this fire resistance test is drawn to the fact that fire testing may be hazardous and that there is a possibility that toxic and/or harmful s

30、moke and gases may be evolved during the test. Mechanical and operational hazards may also arise during the construction of the test elements or structures, their testing and disposal of test residues. An assessment of all potential hazards and risks to health should be made and safety precautions s

31、hould be identified and provided. Written safety instructions should be issued. Appropriate training should be given to relevant personnel. Laboratory personnel should ensure that they follow written safety instructions at all times. BS EN 1366-12:2014EN 1366-12:2014 (E) 6 1 Scope This part of EN 13

32、66 specifies a method for determining the fire resistance of non-mechanical fire barriers installed in fire separating elements designed to withstand heat and the passage of smoke and gases at high temperature. This European Standard is used in conjunction with EN 1363-1 and EN 1366-2. This European

33、 Standard is not suitable for testing non-mechanical fire barriers in suspended ceilings without modification. This European Standard is not suitable for testing fire dampers, see EN 1366-2. This European Standard is not suitable for testing such products as air transfer grilles, as the pressures an

34、d flows involved are different and may cause differing behaviour. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references,

40、mechanical fire barrier or supporting construction and the measuring station 3.4 test construction complete assembly of the test specimen, the connecting duct and the supporting construction 3.5 measuring station equipment installed between the connecting duct and the exhaust equipment to determine

41、the volume flow rate of gases passing through the fire barrier under test 3.6 exhaust equipment equipment consisting of a fan and balancing or dilution barriers (if any), to apply and maintain the underpressure in the connecting duct 4 Test equipment 4.1 General In addition to the test equipment spe

42、cified in EN 1363-1, and if applicable, EN 1363-2, the following is required. Examples of test configurations are shown in Figures 1 and 2. 4.2 Connecting duct The connecting duct shall be of all welded construction fabricated from (1,5 0,1) mm thick steel of the same size (width x height or diamete

43、r) as the non-mechanical fire barrier being tested. The duct shall have a length of two times the diagonal dimension of the non-mechanical fire barrier up to a maximum of 2 m. Where a non-mechanical fire barrier that has a short spigot such that connection to the connecting duct is difficult, this s

44、pigot shall be extended by 500 mm using material of the same type and thickness of the spigot in order to provide a secure air-tight connection without unduly stiffening the non-mechanical fire barrier. This extended spigot shall be all welded the same as the connecting duct. The length of the conne

45、cting duct shall then be reduced by 500 mm. The connecting duct may be provided with a gas tight observation window. Care should be taken in the event of testing to Figure 4, to select a method of connecting the non-mechanical fire barrier to the ductwork to ensure that accurate leakage is recorded.

46、 4.3 Volume flow measuring station This shall consist of a venturi, orifice plate, or other suitable device and (where necessary) an air flow straightener, installed in straight lengths of pipe, all sized to EN ISO 5167-1, EN ISO 5167-2 and EN ISO 5167-3. It shall be installed between the connecting

47、 duct and the exhaust fan to determine the volume flow rate of gases passing through the non-mechanical fire barrier under test. The measuring device shall be capable of measuring to an accuracy of 5 %. Regardless of whether vertical or horizontal non-mechanical fire barriers are being tested, the v

48、olume flow measuring station shall always be used in a horizontal orientation. 4.4 Condensing unit Where materials used in the construction of a non-mechanical fire barrier may generate quantities of steam during the fire test, a condensing unit having provision for drainage shall be installed betwe

When using the condensing device, the temperature recorded by the thermocouple positioned downstream of the flow measuring device described in 4.3 shall not exceed 40 C. 4.5 Gas temperature measuring devices These shall be positioned adjacent to the flow measuring device. A suitable device is a 1,5 mm diameter sheathed thermocouple orientated vertically with its measuring junction located at the centre line of the measuring duct and at
