BS EN 1366-5:2010EN 1366-5:2010 (E) 5 Introductio

20、n The purpose of this test is to measure the ability of a service duct or shaft to resist the spread of fire from one fire compartment to another with fire attack from inside or outside the duct or shaft. The test specimens incorporate joints and access openings as intended in practice and are suspe

21、nded as they would be in practice. Test specimens of service ducts are not loaded as in practice but a standard load is included to represent a typical service load. Test specimens of service shafts are not loaded as in practice, but a standard load is included to represent a typical service load. C

22、AUTION 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. Mechanical and operational hazards

23、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 should be identified and provided. Written safety instructions should be issued. Ap

24、propriate training should be given to relevant personnel. Laboratory personnel should ensure that they follow written safety instructions at all times. BS EN 1366-5:2010EN 1366-5:2010 (E) 6 1 Scope This European Standard specifies a method for determining the fire resistance of horizontal service du

25、cts and vertical service shafts, which pass through walls or floors and enclose pipes and cables. The test examines the behaviour of ducts and shafts exposed to fire from outside and from inside the duct. This European Standard is intended to be read in conjunction with EN 1363-1. This European Stan

26、dard does not examine the risk of fire spread as a result of thermal conduction along the piping installed in service ducts or shafts, or thermal conduction through the media these pipes carry. It does not cover the risk of damage produced by thermal elongation or shortening of tubes and cables as a

27、 result of fire, or damaged pipe suspensions. This European Standard does not give guidance on how to test one, two or three sided service ducts or shafts. NOTE Guidance on testing service ducts and shafts of less than four sides will be covered in the extended field of application rules being devel

28、oped by CEN/TC 127. This test is unsuitable for evaluating service ducts with internal barriers at walls and floors. Whilst the walls of service ducts or shafts tested to this method may provide specified levels of integrity or insulation, testing to this European Standard does not replace the testi

29、ng of the functional endurance of small electrical cables which is covered in EN 50200. Fire resistance testing of ducts for air distribution systems is covered in EN 1366-1. 2 Normative references The following referenced documents are indispensable for the application of this document.

34、 4.1 General In addition to the test equipment specified in EN 1363-1, the following are required. 4.2 Furnace The furnace shall be capable of subjecting service ducts and shafts to the standard heating and pressure conditions specified in EN 1363-1 and be suitable for testing horizontal ducts (see

35、Figures 1 and 2) or vertical shafts (see Figures 3 and 4). 4.3 Loading equipment Stranded steel cables are used to apply load to the bottom internal face of the service duct to represent service loading, or any other equivalent equipment. 4.4 Gas extraction equipment (optional) If for safety reasons

36、 a laboratory requires to extract gases away from the open end of the duct or shaft, this shall not influence the test conditions. 5 Test conditions 5.1 Furnace The heating and pressure conditions and the furnace atmosphere shall conform to those given in EN 1363-1. 5.2 Loading Horizontal service du

37、cts shall be loaded when supporting service installations. In this case, the load shall be representative of that used in practice. Vertical service shafts shall not be loaded except in the two following situations: when supporting service installations. In this case, the load shall be representativ

38、e of that used in practice; when the service installation shaft is not fixed to each floor or when the height between two supports is greater than 5 m. In this case a weight load shall be added to the shaft length of the next floor. BS EN 1366-5:2010EN 1366-5:2010 (E) 8 6 Test specimen 6.1 Size 6.1.

39、1 General Any size of duct or shaft may be tested as required by the sponsor. However, sizes other than those in Tables 1 and 2 may have restricted direct field of application. 6.1.2 Length The minimum lengths of the parts of the test specimen inside and outside the furnace shall be as given in Tabl

43、neral Ducts shall be arranged as shown in Figures 1 and 2 and shafts shall be arranged as shown in Figures 3 and 4. Service ducts or shafts with fire exposure from outside will have no openings in the furnace (except access panels). For service ducts or shafts exposed to an internal fire, the end of

44、 the duct facing into the furnace shall be left open. No ducts or shafts shall contain anything other than the standard cables for loading. The exposure condition (fire inside or fire outside) shall be as specified by the sponsor. Where used in practice, each service duct or shaft shall incorporate

45、one access opening as follows: fire outside: inside furnace at mid-span of exposed section of duct; fire inside: as shown in Figure 2 (the dimensions may be applied also to vertical shafts). For the test, the access opening shall be at the bottom of the duct. The size of the access opening shall be

46、representative of practice. Vertical shafts shall be arranged as shown in Figures 3 and 4 and shall penetrate through the furnace roof slab/supporting construction. The shafts shall be fixed at the furnace roof level as they would be fixed in practice when penetrating a floor (as specified by the sp

47、onsor). 6.3.2.2 Joints in horizontal ducts The test configuration shall include at least one joint inside the furnace and at least one joint outside it. There shall be at least one joint for every layer of fire protection material, both inside and outside the furnace and in any steel duct. Outside t

48、he furnace, the joint in the outer layer of the fire protection material shall be no further than 700 mm from the supporting construction and no nearer than 100 mm to thermocouples T2 in accordance with 9.1. Inside the furnace, the joint in the outer layer of fire protection material shall be locate

49、d at approximately mid-span. The location of joints in inner layers shall be as specified by the sponsor. The distance between joints and suspension devices shall not be less than that used in practice. If the minimum distance has not been specified, suspension devices shall be arranged so that the joint at mid-span lies
