This European Standard shall be given the status
13、of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2010, and conflicting national standards shall be withdrawn at the latest by September 2010. Attention is drawn to the possibility that some of the elements of this document may be the su
14、bject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1366-5:2003. This document includes a bibliography. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the follo
15、wing countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slova

EN 1366-5:2010 (E) 5 Introduction 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 shaf
17、t. The test specimens incorporate joints and access openings as intended in practice and are suspended 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
18、 not loaded as in practice, but a standard load is included to represent a typical service load. 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
19、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 should be made and safe
20、ty 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. EN 1366-5:2010 (E) 6 1 Scope This European Standar
21、d specifies a method for determining the fire resistance of horizontal service ducts 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
22、Standard is intended to be read in conjunction with EN 1363-1. This European Standard 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 ris
23、k of damage produced by thermal elongation or shortening of tubes and cables as a 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
24、four sides will be covered in the extended field of application rules being developed 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 inte
25、grity or insulation, testing to this European Standard does not replace the testing 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 referen
26、ced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

31、 in EN 1363-1 and be suitable for testing horizontal ducts (see 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 equipmen
32、t. 4.4 Gas extraction equipment (optional) If for safety reasons 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 confor
33、m to those given in EN 1363-1. 5.2 Loading Horizontal service ducts 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 serv
34、ice installations. In this case, the load shall be representative 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. EN

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 an
36、d outside the furnace shall be as given in Table 1.

39、uct and shaft arrangement 6.3.2.1 General 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 exp
40、osed to an internal fire, the end of 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 serv
41、ice duct or shaft shall incorporate 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
42、size of the access opening shall be 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 penetra
43、ting a floor (as specified by the sponsor). 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 furn
44、ace and in any steel duct. Outside the 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
45、 protection material shall be located 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 d
46、evices shall be arranged so that the joint at mid-span lies midway between them. Centres of the suspension devices shall be specified by the sponsor and shall be representative of practice. 6.3.2.3 Joints in vertical service shafts For the vertical shaft exposed to fire from inside, the test configu
47、ration shall include at least one joint inside the furnace and 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 the furnace, the joint in the outer layer of the fire protection mate
48、rial 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 located at approximately mid- span. The location of joints in inner layers
49、 shall be as specified by the sponsor. For the vertical shaft exposed to fire from outside, the test arrangement shall include at least one joint inside and one joint outside the furnace. There shall be at least one joint both inside and outside the furnace in every layer of fire protection material. Outside the furnace, for both the shaft exposed to fire from inside and that expos
