1、Designation: E 2061 09An American National StandardStandard Guide forFire Hazard Assessment of Rail Transportation Vehicles1This standard is issued under the fixed designation E 2061; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision,

2、 the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe traditional approach to codes and standards is the specification of individual fire-test-responserequ

3、irements for each material, component, or product that is found in a given environment and isdeemed important to maintain satisfactory levels of fire safety. This practice has been in place for solong that it gives a significant level of comfort; manufacturers know what is required to comply withthe

4、 specifications and specifiers simply apply the requirements. The implicit assumptions are notstated, but they are that the use of the prescribed requirements ensures an adequate level of safety.There is no need to impose any change on those manufacturers who supply safe systems meetingexisting pres

5、criptive requirements; however, as new materials, components, and products aredeveloped, manufacturers, designers, and specifiers often desire the flexibility to choose how overallsafety requirements are to be met. It is the responsibility of developers of alternative approaches tostate explicitly t

6、he assumptions being made which result in a design having an equivalent level ofsafety. One way to generate explicit and valid assumptions is to use a performance-based approach,based on test methods that provide data in engineering units, suitable for use in fire safety engineeringcalculations, as

7、this guide provides.This fire hazard assessment guide focuses on rail transportation vehicles. Such a fire hazardassessment requires developing all crucial fire scenarios that must be considered and consideration ofthe effect of all contents and designs within the rail transportation vehicle, which

8、will potentially affectthe resulting fire hazard. The intention of this guide is that rail transportation vehicles be designedeither by meeting all the requirements of the traditional prescriptive approach or by conducting a firehazard assessment, that needs to provide adequate margins of error, in

9、which a level of safety isobtained that is equal to or greater than the level of safety resulting from the traditional approach.1. Scope1.1 This is a guide to developing fire hazard assessments forrail transportation vehicles. It has been written to assistprofessionals, including fire safety enginee

10、rs, who wish toassess the fire safety of rail transportation vehicles, during orafter their design (see also 1.6). This guide is not in itself a firehazard assessment nor does it provide acceptance criteria; thus,it cannot be used for regulation.1.2 Hazard assessment is a process that results in ane

11、stimate of the potential severity of the fires that can developunder defined scenarios, once defined incidents have occurred.Hazard assessment does not address the likelihood of a fireoccurring. Hazard assessment is based on the premise that anignition has occurred, consistent with a specified scena

12、rio, andthat potential outcomes of the scenario can be reliably esti-mated.1.3 Consistent with 1.2, this guide provides methods toevaluate whether particular rail passenger designs provide anequal or greater level of fire safety when compared to designsdeveloped based on the traditional applicable f

13、ire-test-responsecharacteristic approaches currently widely used in this indus-try. Such approaches have typically been based on prescriptivetest methodologies. The following are examples of such lists ofprescriptive tests: the requirements by the Federal RailroadAdministration (FRA) (Table X1.1), t

14、he former guidelines ofthe FRA, the requirements of NFPA 130 (Table X3.1), and therecommended practices of the Federal Transit Administration(FTA). Selective use of parts of the methodology in this guideand of individual fire-test-response characteristics from TableX1.1 (or any other set of tests) d

15、oes not satisfy the fire safetyobjectives of this guide or of the table. This guide shall be usedin its entirety to develop a fire hazard assessment for railtransportation vehicles or to aid in the design of such vehicles.1.4 This guide includes and applies accepted and clearlydefined fire safety en

18、.1.5 This guide provides recommended methods to mitigatepotential damage from fires in rail transportation vehicles, byassessing the comparative fire hazard of particular products,assemblies, systems or overall designs intended for use in railtransportation vehicles. Such methods could include chang

19、es tothe materials, components, products, assemblies, or systemsinvolved in the construction of the rail transportation vehicle orchanges in the design features of the vehicle, including thenumber and location of automatically activated fire safetydevices present (see 4.4.4 for further details).1.6

20、This guide is intended, among other things, to be ofassistance to personnel addressing issues associated with thefollowing areas.1.6.1 Design and specification of rail transportation ve-hicles.1.6.2 Fabrication of rail transportation vehicles.1.6.3 Supply of assemblies, subassemblies, and componentm

21、aterials, for use in rail transportation vehicles.1.6.4 Operation of rail transportation vehicles.1.6.5 Provision of a safe environment for all occupants of arail transportation vehicle.1.7 The techniques provided in this guide are based onspecific assumptions in terms of rail transportation vehicle

22、designs, construction and fire scenarios. These techniques canbe used to provide a quantitative measure of the fire hazardsfrom a specified set of fire conditions, involving specificmaterials, products, or assemblies. Such an assessment cannotbe relied upon to predict the hazard of actual fires, whi

23、chinvolve conditions, or vehicle designs, other than those as-sumed in the analysis. In particular, the fire hazard may beaffected by the anticipated use pattern of the vehicle.1.8 This guide can be used to analyze the estimated fireperformance of the vehicle specified under defined specific firesce

24、narios. Under such scenarios, incidents will begin eitherinside or outside a vehicle, and ignition sources can involvevehicle equipment as well as other sources. The fire scenariosto be used are described in detail in Section 5.3.1.8.1 Fires with more severe initiating conditions than thoseassumed i

25、n an analysis may pose more severe fire hazard thanthat calculated using the techniques provided in this guide. Forthis reason severe fire conditions must be considered as part ofan array of fire scenarios.1.9 This fire standard cannot be used to provide quantitativemeasures.2. Referenced Documents2
