DIN EN 1366-12:2014-12EN 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) to prevent fire and smoke spreading from one fire compartment to another through the air ductwork system whic
28、h 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 to be closed except under fire conditions. The non-mechanical fire barrier is attached (directly or remotely
29、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 expose it to furnace conditions. Temperature and integrity measurements are carried out in various parts of
30、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 pressure differential across the closed non-mechanical fire barrier of 300 Pa. Caution: The attention of al
31、l 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 smoke and gases may be evolved during the test. Mechanical and operational hazards may also arise during the
32、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 should be identified and provided. Written safety instructions should be issued. Appropriate training should
33、be given to relevant personnel. Laboratory personnel should ensure that they follow written safety instructions at all times. DIN EN 1366-12:2014-12EN 1366-12:2014 (E) 6 1 Scope This part of EN 1366 specifies a method for determining the fire resistance of non-mechanical fire barriers installed in f
34、ire 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 Standard is not suitable for testing non-mechanical fire barriers in suspended ceilings without modific
35、ation. 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 and flows involved are different and may cause differing behaviour. 2 Normative references The following d

Examples of test confi
44、gurations 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 diameter) as the non-mechanical fire barrier being tested. The duct shall have a length of two times the di
45、agonal 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 spigot shall be extended by 500 mm using material of the same type and thickness of the spigot in ord
46、er 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 connecting duct shall then be reduced by 500 mm. The connecting duct may be provided with a gas tight obs
47、ervation 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. 4.3 Volume flow measuring station This shall consist of a venturi, orifice plate, or other suitable
48、 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 duct and the exhaust fan to determine the volume flow rate of gases passing through the non-mechani
49、cal 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 volume 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 havi
