BS EN 1364-2:2018EN 1364-2:2018 (E) 5 Introduction This European Sta

31、ndard has been prepared to provide a method of test for assessing the fire resistance of non-loadbearing ceilings. It is applicable to self-supporting ceilings as well as suspended ceilings, with either fire from below of from above. This European Standard is not applicable to loadbearing systems. T

32、he fire resistance of loadbearing floors in conjunction with a suspended ceiling should be assessed by using EN 1365-2. 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

33、possibility that toxic and/or harmful smoke 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

34、should be made and safety precautions should 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. Safety note Monitoring for

35、integrity by the cotton pad or other means and insulation by use of the roving thermocouple 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

36、 considered and appropriate precautions taken to protect operators from radiation, smoke, hot gases and from contact with furnace flame. Operators should 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 ca

37、rry out inspection tests of any type during the test. BS EN 1364-2:2018EN 1364-2:2018 (E) 6 1 Scope This part of EN 1364 specifies a method for determining the fire resistance of ceilings, which in themselves possess fire resistance independent of any building element above them. This European Stand

38、ard is used in conjunction with EN 1363-1. The method is applicable to ceilings, which are either suspended 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 ei

39、ther: a) from below the ceiling, or b) from above the ceiling to simulate fire within the cavity above the ceiling. The contribution to fire resistance which a suspended ceiling might provide as a protective membrane to loadbearing elements is determined using the procedure given in EN 13381-1. The

40、fire resistance of loadbearing floors in conjunction with a suspended ceiling can also be assessed by using tests according to EN 1365-2. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

47、363-2. 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 the size of the furnace opening, then it shall be tested at a size of at least 4 m 3 m. The span of the ceiling shall be in the direction o

48、f the larger dimension (see also 6.3.2). When the ceiling in practice is smaller than 4 m 3 m, in either direction, then it shall be tested at full size. The furnace aperture shall be closed with some elements of adequate size, with the stiffness and stability required to support the test specimen.

49、6.1.2 Suspended ceilings exposed to fire from below or from above The test specimen shall be of size so that at least 4 m 3 m is exposed to the furnace conditions. The direction of the main components (see 6.3.2) shall be in the direction of the larger dimension. When the ceiling in practice is smaller than 4 m 3 m, in either direction, then it shall be tested at full size. The furnace aperture shall be closed with some elements of adequate size, with the stiffness and stability required to support the test specimen. BS EN 1364-2:2018EN
