25、545-7:2013 (E) 4 Introduction EN 45545-7 has been developed from existing fire safety regulations for railway vehicles from the International Union of Railways (UIC) and different European countries. In using the Operation and Design Categories defined in EN 45545-1, the requirements laid down in th

26、is part take into account the current operating conditions for European public rail transport. DIN EN 45545-7:2013-08 EN 45545-7:2013 (E) 5 1 Scope This part of EN 45545 specifies requirements for flammable liquids and liquefied petroleum gas installations, e. g. for traction, auxiliary power units,

27、 heating or cooking, to cover the objectives defined in EN 45545-1. This part is not applicable to technical liquids themselves, e. g. hydraulic liquid and transformer oil, except where guidance is given as to dealing with spillages, leakage and spray generation. The measures and requirements specif

28、ied in this European Standard aim to protect passengers and staff in railway vehicles by preventing a fire from occurring and spreading by leakage of flammable liquids or gases. It is not within the scope of this European Standard to describe measures for flammable gases, other than liquefied petrol

29、eum gases (LPGs). It is not within the scope of this European Standard to describe measures that ensure the preservation of the railway vehicles in the event of a fire. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensa

33、he following factors shall be considered: possible sources and paths of leakage, and for LPG installations, there shall be means of detecting any leakage; flammability characteristics of flammable liquids and gases including the effects of any combustible or absorbing materials; possible ignition so

34、urces, including electrical faults, overheating of equipment, and malfunctioning of protective devices; DIN EN 45545-7:2013-08 EN 45545-7:2013 (E) 6 means available for detecting, controlling or extinguishing a fire, such as stopping the flow of flammable liquids, shutting down equipment, fire resis

35、ting containment, or the use of extinguishing media. The design of flammable liquid, gas and LPG installations shall take into account relevant design load cases for static and dynamic conditions. Flammable liquid spray or any flammable atmosphere shall be prevented from coming into contact with pot

36、ential ignition sources, e. g. hot surfaces or high power electrical switch gear. Leakage of fuel and oil shall be minimized under normal operation conditions. In each area where a flammable liquid or a flammable gas might escape, there shall be means to reduce: a) the probability of ignition; and b

37、) the consequences if ignition does occur. Some materials that have a fire prevention function may be operating at an elevated temperature as a result of being near equipment operating at high temperatures (e. g. exhaust pipe insulation). In such cases, degradation of the material could impair its a

38、bility to perform its function, and its propensity to ignite may be increased. Care shall be taken to ensure that such materials will not degrade in this manner. Metal containers and pipes fixed permanently on railway vehicles or stored movable containers shall be electrically bonded to the rail via

39、 the vehicle structure in accordance with EN 50153. For each metal used for flammable liquid or flammable gas installations, certified material test reports or test certificates according to EN 10204 shall be submitted. When selecting materials used in the vicinity of equipment which may generate fl

40、ammable liquids or gases, care shall be taken to ensure that the material surface cannot absorb these species. 5 Flammable liquids and gas tanks 5.1 General Tanks shall be built, located or protected so that they or their piping cannot be punctured or fractured by debris thrown up from the track. Ta

41、nks shall not be installed in: energy absorption zones; passenger areas; luggage compartments; drivers cabs. For tanks that are divided internally by partition walls, the complete tank shall fulfil these requirements. 5.2 Tanks for flammable liquids Tanks constructed to the following requirements ar

42、e deemed to satisfy the minimum impact performance. If other materials are used, equivalent safety shall be demonstrated. The thickness of walls shall have a minimum according to Table 1. DIN EN 45545-7:2013-08 EN 45545-7:2013 (E) 7 Table 1 Minimum thickness of walls Volume Steel Aluminium 2 000 dm3

43、2,0 mm 3,0 mm 2 000 dm33,0 mm 4,0 mm Tanks for flammable liquid shall be located and designed so that no ignition can occur at normal temperatures. The design of flammable liquid tanks shall ensure, as far as reasonably practicable, that during filling or draining or in the event of leakage from a t

44、ank or its pipe work, flammable liquids cannot: come into contact with rotating machinery which might result in a spray; be drawn into any device in suction e. g. ventilators and coolers; come into contact with hot components, or electrical devices which may produce an electrical spark; penetrate in

45、to layers of thermal or acoustic insulation material. Tanks for flammable liquids shall not be filled more than 90 % of their nominal volume. Filling limit indicators shall be provided. The output from a limit indicator device shall be easy to read from the filling position. To avoid confusion, the

46、kind of appropriate flammable liquid shall be clearly labelled at or adjacent to the filling pipe of the tank. The labelling of the flammable liquid shall be given textual in accordance to safety data sheets according to ISO 11014. In the vicinity of the filling pipe the following danger signs shall

47、 be displayed: danger sign P02 “No naked flames, no smoking” in accordance with Directive 92/58/EEC (see Figure A.1); danger sign W01 “Warning of flammable liquids“ in accordance with Directive 92/58/EEC (see Figure A.2). Design of the filler pipes or other openings shall ensure that flammable liqui

48、d shall not escape during normal operating conditions, taking into account any system movement as a result of suspension movements. 5.3 Portable liquefied petroleum gas installation for catering purposes The LPG cylinders and the equipment to which they are connected shall be situated in the same railway vehicle. The coupling of LPG installations between several railway vehicles is prohibited. LPG cylinders shall be located in cylinder cabinets made from sheet metal. LPG cylinders
