23、zation Provided by IHS under license with CENELECNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-BS EN 50553:2012- 5 - EN 50553:2012 Introduction The purpose of this European Standard is to define requirements for running capability under fire conditions which are
24、applicable to railway rolling stock with passengers, so that a train will be able to reach a “safe area“ as defined in the Safety in Rail Tunnels TSI (TSI SRT) 1.1.3. Specifically, this standard is intended to clarify and rationalise the requirements for rolling stock running capability in the EN 45
25、545 series (Operation Categories 2, 3 and 4) and in the TSI SRT (Fire Safety Categories A and B). It is also intended to define specific technical measures, compliance with which will allow a Presumption of Conformity with the TSI SRT to be made by the Notified Body assessing the Rolling Stock. NOTE
26、 1 In several cases it might appear that requirements are included which are duplicating requirements given in the EN 45545 series and/or which are dealt with in other ways by the EN 45545 series. This is not the intention and is not the case. The EN 45545 series introduces running capability functi
27、onal requirements but does not generally define how they are to be met nor to what level of performance. Also, a number of requirements which are included in the EN 45545 series, would be relevant to, or suitable for, running capability use but are not identified for this use within the TS. It is th
28、erefore necessary to include requirements which are apparently duplicating the EN 45545 series in this standard but which actually do not duplicate the TS when examined in detail. If desired it should be possible, when converting EN 45545 to an EN, to include these requirements during the process wh
29、ich would allow them to be removed from this standard. Reference to Annex A shows that it is necessary for this standard specifically to address 4.2.5.5 of the TSI SRT. This standard considers the requirement to “improve the probability that a passenger train with a fire on board will continue to op
30、erate“ in a “reasonably practicable“ context. It is understood that “train“ includes all vehicles such as locomotives and power cars which are associated with the passenger vehicles. Requirements for running capability cannot be defined without a knowledge of other fire characteristics of the train,
31、 specifically its reaction to fire and fire resistance specification. The assumption is made that the fire standard applied is the EN 45545 series or any standard for which technical equivalence can be demonstrated. NOTE 2 In defining conditions to assure running capability it is only the intention
32、to define requirements which allow the train to remain capable of controlled movement. The general safety level of the train when operating under these conditions (for example the level of lighting within the saloon) is not within the scope. Matters such as this are dealt with in other standards (in
33、cluding, but not limited to, the EN 45545 series). The standard defines requirements based on a philosophy which recognises that stopping a train is not itself a life-threatening event. It is therefore not required to have running capability for all fires; only those fires which may cause serious in
34、jury and/or develop to threaten life. For example, situations such as the combustion of an individual electrical component inside a technical cabinet meeting criteria for fire resistance in accordance with the EN 45545 series, do not attract running capability requirements under this standard. In a
35、similar manner, if any fire is extinguished with no reignition during the relevant period of the incident, it is deemed that there is no longer a requirement for running capability and the train can be stopped (as if it was a non-safety threatening technical fault). These examples illustrate how the
36、 impracticability of addressing all thermal events that could stop a train is circumvented by the philosophy applied. Compliance with the running capability requirements for any relevant system function is derived from one or more of the following: absence of a relevant fire; assuring system functio
37、n under the fire; assuring system function for a redundant array under the fire; extinguishing the fire; assuring sufficient remaining Tractive Effort under the fire.

In
41、particular, technical measures are specified, compliance with which will contribute to conformity with the Directive and the relevant Technical Specifications for Interoperability (TSI). The standard specifies the fire conditions: for which it is not necessary to define running capability requiremen
42、ts as there is no significant potential for serious injury or threat to life; for which it is reasonable to expect trains to continue to run in a controlled manner; for which it is not reasonably practicable to define requirements which give complete assurance of running in a controlled manner, due
43、to the exceptional nature of the fire incident. The TSI SRT defines running capability requirements in respect of fires within technical areas/equipment only. However for general guidance the scope of this standard is extended to include fires from non-technical causes within passenger/staff areas w
44、hich may impact train system functions adjacent to and/or passing through the affected area. This extension of applicability significantly increases the number of system functions which are potentially at risk and therefore requires that the “reasonably practicable“ principles be extended to this ne
45、w condition. The standard does not consider situations where a primary non-fire incident is likely to immobilise the train by definition; for example major mechanical defect leading to derailment, even when fire then occurs. 2 Normative references The following documents, in whole or in part, are no
