25、is standard a representative sample of a raised or hollow floor is exposed to a specified regime of heating and loading. The performance of the test specimen is monitored on the basis of criteria described in EN 1363-1. The fire resistance of the tested construction is expressed as the time for whic
26、h the appropriate criteria have been satisfied. Caution The attention of all persons concerned with managing and carrying out this fire resistance test, EN 1366-6, is drawn to the fact that fire testing can be hazardous and that there is a possibility that toxic and/or harmful smoke and gases can be
27、 evolved during the test. Mechanical and operation hazards can 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 should be identified and
28、 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. Licensed Copy: sheffieldun sheffieldun, na, Sun Oct 29 09:35:57 GMT+00:00 2006, Uncontrol
29、led Copy, (c) BSI EN 1366-6:2004 (E) 6 1 Scope This Part of EN 1366 specifies a method for determining the fire resistance of raised access floors and hollow floors when subjected to a fire from within the plenum beneath the floor. The fire exposure applied to the test specimen may be either: a) sta
30、ndard time temperature curve; b) reduced time temperature curve which follows the standard time/temperature curve only up to 500 C. After this temperature has been reached the temperature within the furnace is maintained at 500 C. This document does not determine the fire resistance of the sub-floor
31、 on which the raised or hollow floor is constructed; this is given in EN 1365-2. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the r

33、ocument, the terms and definitions given in EN 1363-1:1999, EN 12825:2001, EN 13213:2001 and EN ISO 13943:2000 and the following apply. 3.1 raised access floor factory made flooring system comprising panels supported on an under-structure of pedestals and/or stringers or other components as applicab
34、le, providing a load bearing structure for the fitting out of a building (EN 12825) NOTE The under-structure is part of the raised access floor. 3.2 stringer horizontal component connecting pedestals that may support a panel 3.3 hollow floor loadbearing layer supported by a special understructure (w
35、hich may include pedestals) in order to provide a space between the loadbearing layer and the base floor for installation of e.g. telecommunication services, electrical supplies, heating or air conditioning 3.4 sub-floor horizontal element of building construction which is loadbearing and separating

It is supported by the under structure (e.g. pedestals and stringers) (EN 12825) 3.6
37、 pedestal vertical component or part of the element which transmits loading to the sub-floor (EN 12825) 3.7 plenum available space between the underside of the panels of the access floor and the sub-floor (EN 12825) 3.8 plenum height vertical distance between the highest point of the sub-floor and t
38、he lowest point of the underside of the access floor or hollow floor 3.9 associated construction walls applied at the periphery of the test specimen representative of those in practice 3.10 fittings items contained within raised access flooring systems or hollow flooring systems which penetrate pane
39、ls or the hollow floor, e.g. ventilation grills, power sockets 3.11 unexposed face upper surface of the raised or hollow floor, i.e. the opposite surface to the surface exposed to fire 4 Test equipment The test equipment shall be as specified in EN 1363-1. 5 Test conditions 5.1 Furnace temperature W
40、hen testing using the standard time temperature curve, the furnace atmosphere and heating conditions shall conform to those given in EN 1363-1. When testing using the reduced time temperature curve, the furnace atmosphere shall conform to EN 1363-1 and the temperature in the furnace shall follow the
41、 standard time temperature curve until 500 C has been reached. 5.2 Furnace pressure 5.2.1 Plenum heights not greater than 1,0 m The pressure in the plenum 100 mm below the lowest point of the underside of the panel or horizontal part of the floor shall be maintained at (+ 5 3) Pa relative to the out
42、side of the furnace. 5.2.2 Plenum heights greater than 1,0 m The pressure in the plenum 100 mm below the lowest point of the underside of the panel or horizontal part of the floor shall be maintained at a pressure calculated as follows: Licensed Copy: sheffieldun sheffieldun, na, Sun Oct 29 09:35:57
43、 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 1366-6:2004 (E) 8 p = 8,5 h 3,5 where p = pressure in Pa; h = height of plenum in m. 5.3 Loading conditions The test specimen shall be subjected to loads determined in accordance with EN 1363-1. The determination of the load shall be clearly indicated i
44、n the test report. The sponsor shall decide on the magnitude and distribution of the load, which may be uniformly distributed or applied to discrete areas. NOTE 1 Figure 1 shows a suggested pattern of distribution for applying load to discrete areas. NOTE 2 The level of load required may be subject
45、to national provisions. A suggested minimum value of the test load is 1,5 kN/m2. Loading may be applied using weights, hydraulic rams or other mechanical systems. The total contact area of the loading equipment on the floor surface shall be not more than 0,09 m2 at any individual loading position or
46、 20 % of the total surface area collectively. If the load is applied via materials with a high conductivity, e.g. steel plates, then they shall be insulated from the surface of the test specimen. The loading equipment shall not inhibit the free movement of air at the top of the test specimen and, ot
47、her than at the loading points, no part of the loading equipment shall be closer than 60 mm to the unexposed surface of the test specimen. 6 Test specimen 6.1 Size a) The test specimen shall be full size unless the actual size is larger than the size that can be accommodated in the furnace. b) When
48、the actual size cannot be accommodated in the furnace, the dimensions of the test construction shall be such that at least the following dimensions of the test specimen are exposed to the fire: exposed length: 4 000 mm, exposed width: 3 000 mm. 6.2 Number One test specimen shall be tested for each s
49、pecified support/restraint, or exposure and loading, condition. More than one test will be necessary if one test cannot adequately cover all of the constructional variations given in 6.3.
