18、e is contained in a closed cavity. 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 smoke and gases may be evolved during the test.
19、 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 ali potential hazards and risks to health shall be made and safety precautions shall be identified and provided. Written safety
20、 instructions shall be issued. Appropriate training shall be given to relevant personnel. Laboratory personnel shall ensure that they follow written safety instructions at all times. Safety note: Monitoring for integrity by the cotton pad or other means and insulation by use of the roving thermocoup
21、le from above a test specimen (in the case of fire from below) or within a void beneath a fire test specimen (in the case of fire from above) can be hazardous unless the risks associated with these practices are considered and appropriate precautions taken to protect operators from radiation, smoke,
22、 hot gases and from contact with furnace flame. Operators shall not reach over the test specimen (in the case of fire from below) or enter the void beneath a test specimen (in the case of fire from above) to carry out inspection tests of any type during the test.

23、 Scope This part of EN1364 specifies a method for determining the fire resistance of ceilings, which in themselves possess fire resistance independent of any building element above them. This standard is used in conjunction with EN 1363-1. The method is applicable to ceilings, which are either suspe
24、nded by hangers or fixed directly to a supporting frame or construction, and to self supporting ceilings. Within this test method, the ceiling is exposed to fire, with the exposure being applied either: a) from below the ceiling, or b) from above the ceiling to simulate fire within the cavity above
25、the ceiling. The contribution to fire resistance which a suspended ceiling may provide as a protective membrane to loadbearing elements is determined using a procedure which will be given in an ENV in preparation. 2 Normative references This European Standard incorporates by dated or undated referen
26、ce provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this standard only when incorporated in it by
27、 amendment or revision. For undated references the latest edition of the publication referred to applies.

28、:1998) 3 Definitions For the purposes of this Part of EN 1364 the definitions given in EN 1363-1 and prEN IS0 13943, together with the following, apply: 3.1 ceiling: A non-loadbearing element of a building construction designed to provide horizontal fire separation. 3.2 self-supporting ceiling: A ce
29、iling with a span from wall to wall, without any additional suspension devices. OBSI 11-1999 Page 6 EN 1364-2: 1999 3.3 suspended ceiling: A ceiling which is suspended from a supporting construction. 3.4 cavity: The space between the upper surface of the ceiling and the underside of any floor, roof
30、or its supporting construction. 3.5 test specimen: The full ceiling specimen submitted for test, including hangers, fittings, insulating materials and features such as lighting, ventilation and access and inspection panels. 3.6 standard supporting construction: A horizontal loadbearing construction
31、to which a suspended ceiling is attached for the test. 3.7 fittings: All devices penetrating the ceiling, e.g lighting and ventilation systems not otherwise covered by a specific fire test. 4 Test equipment The test equipment shall be as specified in EN 1363- 1 or, if appropriate, EN 1363-2. 5 Test
32、conditions The heating and pressure conditions and the furnace atmosphere shall conform to those given in EN 1363- 1 or, if applicable, EN 1363-2. 6 Test specimen 6.1 Size 6.1.1 Self-supporting ceilings exposed to fire from below or from above When the ceiling in practice is equal to or greater than
33、 the size of the furnace opening, then it shall be tested at a size of at least (4 x 3) m. The span of the ceiling shall be in the direction of the larger dimension. (see also 6.3.2). When the ceiling in practice is smaller than (4 x 3) m, in either direction, then it shall be tested full size and t
34、he furnace aperture shall be provided with closures of adequate fire resistance around the extremities of the test specimen. 6.1.2 Suspended ceilings exposed to fire from below and above The test specimen shall be of size such that at least (4 x 3) m is exposed to the furnace conditions. The directi
35、on of the main components (see 6.3.2) shall be in the direction of the larger dimension. OBSI 11-1999 STD-BSI BS EN 13bq-Z-ENGL 1799 M Lb2qbb OB11705 T77 H Page 7 EN 1364-2: 1999 When the ceiling in practice is smaller than (4 x 3) m, in either direction, then it shall be tested full size and the fu
36、rnace aperture shall be provided with closures of adequate fire resistance around the extremities of the test specimen. 6.2 Number A single test specimen shall be tested unless the most onerous test configuration, identified in 6.3.2, cannot be defined, in which case separate tests shall be carried
37、out for each configuration. 6.3 Design 6.3.1 General The test specimen shall be fully representative of the ceiling intended for use in practice. It shall model the edges between the ceiling and walls, the joints and jointing materials to be used in practice. It shall be designed to be mounted only
38、from below. The test specimen shall include any appropriate fittings which are an essential part of the specimen and may influence its behaviour in test. Where fixtures and fittings do not form an integral part of the ceiling but may be fitted subsequently in a manner that may affect the fire resist
39、ance of the ceiling, then these shall be the subject of a separate full size test incorporating those fittings. When the ceiling design includes both longitudinal and transverse joints, the test specimen shall include both such joints. 6.3.2 Orientation If the longitudinal and transverse directions
40、of the ceiling are constructed differently, the performance of the test specimen may vary depending upon the direction aligned with the longitudinal axis. The specimen shall be designed to represent the most onerous condition by arranging the more critical components parallel to the longitudinal axi
41、s. If the more onerous condition cannot be identified, two separate tests shall be carried out with the components arranged both parallel and perpendicular to the longitudinal axis. 6.3.3 Support conditions The following support conditions for the ceilings are specified and shall be followed unless
42、the sponsor requests otherwise. In this case the differing support conditions shall be described in the test report and the validity of the results shall be restricted accordingly. Cavity barriers incorporated as a part of the test specimen are allowed. When the test specimen is full size in both di
43、rections, it shall be fixed as in practice. When it is smaller in one or both directions than in practice the following support conditions shall apply: a) for a self supporting ceiling, there shall be one free edge which shall be in the direction of the main supporting member. There shall be no allo
44、wance made for longitudinal movement of the edges or thermal expansion in either direction, other than that provided for in the ceiling system. OBSI 11-1999 Page 8 EN 1364-2:1999 b) for a suspended ceiling, with fire from below, all edges shall be fixed to the specimen support frame without any allo
45、wance for longitudinal movement of the edges or thermal expansion in either direction, other than that provided for within the ceiling system. c) for a suspended ceiling, with fire from above, two adjacent edges shall be fixed to the specimen support frame without any allowance for longitudinal move
46、ment of the edges or thermal expansion in either direction other than that provided for within the ceiling system. No gap around the specimen is allowed on the four edges. 6.4 Construction The test specimen shall be constructed as described in EN 1363-1. 6.5 Verification Verification of the test spe
47、cimen shall be carried out as described in EN 1363- i. 7 Installation of test specimen 7.1 General The test specimen shall be installed as far as possible in a manner representative of its use in practice. It shall be mounted from below without access from above, and be installed by the same method
48、and procedures recommended in the installation manual which shall be provided by the sponsor. The test specimen shall be mounted in a test frame or furnace to prohibit thermal elongation. Grid members shall be tightly fitted to a test frame or furnace walls in order that the thermal expansion behavi
49、our of grid members and expansion devices may be correctly evaluated. Profiles bearing the various components or panels of the ceiling shall be installed against each other without any gap, unless a gap or gaps is required for design purposes. In this case the gap or gaps shall be representative of practice and shall be installed within the test specimen and not at its perimeter. Provisions for sealing the furnace shall be made when the test specimen is smaller than the furnace aperture. 7.2 Standard supporting construction 7.2.1 General The test specimen shall be installed using
