20、ent (EN 14390:2007) has been prepared by Technical Committee CEN/TC 127 “Fire safety in buildings”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 20

21、07, and conflicting national standards shall be withdrawn at the latest by July 2007. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, E

EN 14390:2007 (E) 6 Introduction This method is intended to describe th

23、e fire behaviour of a product under controlled laboratory conditions. The test method may be used as part of a fire hazard assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a product in a particular end use. WARNING So that suitable pre

24、cautions can be taken to safeguard health, the attention of all concerned in fire tests is drawn to the possibility that toxic or harmful gases can be evolved during combustion of test specimens. The test procedures involve high temperatures and combustion processes from ignition to a fully develope

25、d room fire. Therefore, hazards can exist for burns, ignition of extraneous objects or clothing. The operators should use protective clothing, helmet, face-shield and equipment for avoiding exposure to toxic gases. Means of extinguishing a fully developed fire should be available. EN 14390:2007 (E)

26、7 1 Scope This European Standard specifies a test method to evaluate the reaction to fire performance of building products. A fire is simulated which under well-ventilated conditions starts in a corner of a small room with a single open doorway. The method is intended to evaluate the contribution of

27、 a surface product to fire growth in a room configuration, using a specified ignition source. It constitutes a reference test for this type of product within the European classification system for reaction to fire performance of construction products. The method is particularly suitable for construc

28、tion products which cannot be tested in their end use application in a small or intermediate laboratory scale. The method can also be used to assess the effect of an insulating substrate on the product performance. A test performed in accordance with the method specified in this European Standard pr

29、ovides data for the early stages of a fire from ignition up to flashover. The method is not intended to evaluate floor coverings. It may not be suitable for some free-standing products because their integrity, when exposed to fire, could have a decisive influence on their behaviour. NOTE The term “s

30、urface product” as used in the title and scope of this European Standard specifically relates to internal surface linings, assemblies, pipes and pipe insulation products used in buildings. 2 Normative references The following referenced documents are indispensable for the application of this documen

36、 of the production of smoke during a specified time period 3.9 burning droplets continuous occurrence of flaming droplets/particles from the test specimen for at least 10 s or a pool fire formed on the floor 4 Principle The hazard of fire growth is evaluated in a fire test room by the measurement of

37、 the rate of heat release of the fire based on calculation of oxygen consumption. See also Annex B. The hazard of reduced visibility is estimated by the measurement of the production of light-obscuring smoke. Phenomena attributed to the fire growth, for example flame spread and emission of burning d

38、roplets, are visually documented by photographic and/or video recording. NOTE If further information is required, measurements for example of heat flux to the floor, toxic gas species, the gas temperature in the room and the mass flow in and out the doorway may be performed, see also ISO/TR 9705-2:2

39、001 (Bibliography 2). 5 Fire test room 5.1 Dimensions The room (see Figure 1) shall consist of four walls at right angles, a floor and a ceiling and shall have the following inner dimensions: EN 14390:2007 (E) 9 a) length: (3,6 0,05) m; b) width: (2,4 0,05) m; c) height: (2,4 0,05) m. Dimensions in

40、metres Key 1 front view 2 top view Figure 1 Fire test room The room shall be placed indoors in an essentially draught free, heated space, large enough to ensure that there is no influence on the test fire. In order to facilitate the mounting of the instruments and of the ignition source, the test ro

41、om may be placed so that the floor can be accessed from beneath. 5.2 Doorway There shall be a doorway in the centre of one of the 2,4 m 2,4 m walls and no other wall, floor or ceiling shall have any openings that allow ventilation. The doorway shall have the following dimensions: a) width: 0,8 m 0,0

42、2 m; b) height: 2,0 m 0,02 m. The distance between the top of the doorway and the ceiling shall be (0,4 0,02) m. EN 14390:2007 (E) 10 5.3 Construction material The test room shall be constructed of Class A1 material according to EN 13501-1:2002, with a density of (600 200) kg/m3. The minimum thickne

43、ss of the construction shall be 20 mm. 6 Ignition source 6.1 General The ignition source design is specified in Annex A. The ignition source shall be a propane gas burner having a top surface layer of sand. The construction shall be such that an even gas flow is achieved over the entire opening area

44、. The ignition source is a propane gas burner that consumes relatively large amounts of gas. Attention is therefore drawn to the following warning. All equipment such as tubes, couplings and flowmeters, should be approved for propane. The installations should be performed in accordance with existing

45、 regulations. The burner should, for reasons of safety, be equipped with a remote-controlled ignition device, for example a pilot flame or a glow wire. There should be a warning system for leaking gas and a valve for immediate and automatic cut-off of the gas supply in case of extinction of the igni

46、tion flame. 6.2 Location The burner shall be placed on the floor in a corner opposite to the doorway wall. The top of the burner shall be 145 mm from the floor level. The burner walls shall be in contact with the test specimen. 6.3 Gas The burner shall be supplied with commercial grade propane of at

47、 least 95 % purity. The gas flow to the burner shall be measured with an accuracy of at least 3 %. 6.4 Heat output The net heat output shall be 100 kW during the first 10 min after ignition and then shall be increased to 300 kW for a further 10 min. The heat output from the burner shall be controlle

48、d within 5 % of the prescribed value. 7 Hood and exhaust duct The system for collecting the combustion products shall have sufficient capacity and be designed in such a way that all of the combustion products leaving the fire room through the doorway during a test are collected. The system shall not

49、 disturb the fire-induced flow in the doorway. The maximum exhaust capacity shall be at least 3,5 m3/s at normal pressure and a temperature of 25 C. Exhaust systems based on natural convection shall not be used. NOTE An example of one design of hood and an exhaust duct is given in Annex B. EN 14390:2007 (E) 11 8 Instrumentation in the exhaust duct 8.1 General This clause specifies minimum requirements for instrumentation in the exhaust duct.
