3、ements 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 s

4、pecifications 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 prescr

5、iptive 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 the

6、 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 th

7、is 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 wi

8、ll 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 wh

9、ich 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 engineers

10、, 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 anest

11、imate 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 scenari

12、o, 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 fir

13、e-test-responsecharacteristic approaches currently widely used in this indus-try. Such approaches have typically been based on prescriptive1This guide is under the jurisdiction ofASTM Committee E05 on Fire Standardsand is the direct responsibility of Subcommittee E05.17 on Transportation.Current edi

Selective use of parts

16、 of the methodology in this guideand of individual fire-test-response characteristics from TableX1.1 (or any other set of tests) does not satisfy the fire safetyobjectives of this guide or of the table.

18、nt throughout the world.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 meth

19、ods could include changes 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 fo

20、r further details).1.6 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, subass

21、emblies, and componentmaterials, 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

22、 transportation vehicledesigns, 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 haza

23、rd of actual fires, whichinvolve 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 d

24、efined specific firescenarios. 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 conditi

25、ons than thoseassumed in 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
