CEN/CLC/WG FPR - Fire protection for railway applications

This Part of EN 45545 specifies the fire safety requirements for electrical equipment on railway vehicles, including that of trolley buses, track guided buses and magnetic levitation vehicles. The measures and requirements, specified in this European Standard meet the objective of protecting passengers and staff in railway vehicles in the event of a fire on board by:  lowering the risk of starting a fire both during operation and as a result of technical defect and/or malfunction of the electrical equipment,  ensuring that electrical emergency equipment continues to be functional until evacuation is complete (see FprEN 45545-6).

This part specifies fire safety requirements for railway vehicle design to cover the objectives defined in CEN/TS 45545-1. The measures and requirements specified in this part of the Technical Specification aim to protect passengers and staff in railway vehicles in the event of a fire on board by minimizing the risk of a fire starting, delaying the fire development and controlling the spread of fire products through the vehicle, thus aiding evacuation. It is not within the scope of this Technical Specification to describe measures which ensure the preservation of the vehicles in the event of a fire. This part is valid for railway vehicles defined in CEN/TS 45545-1.

This part specifies requirements for fire detection, alarm systems, equipment shutdown, information and communication systems, emergency lighting, emergency brake systems and fire fighting systems to cover the objectives defined in CEN/TS 45545-1. The measures and requirements specified in this Technical Specification aim to protect passengers and staff in railway vehicles in the event of a fire on board by alerting staff and passengers to a fire, delaying the fire development and controlling the movement of smoke. It is not within the scope of this Technical Specification to describe measures that ensure the preservation of the vehicles in the event of a fire. This part is valid for railway vehicles defined in CEN/TS 45545-1.

This part specifies the fire resistance requirements and testing methods for fire barriers for railway vehicles. The objective of the measures and requirements, specified in this part, is to protect passengers and staff in railway vehicles in the event of a developing fire on board. It is not within the scope of this part to describe measures that ensure the preservation of the vehicles in the event of a fire.

This part specifies the reaction to fire performance requirements for materials and products used on railway vehicles as defined in CEN/TS 45545-1. The operation and design categories defined in CEN/TS 45545-1 are used to establish hazard levels that are used as the basis of a classification system. For each hazard level, this part specifies the test methods, test conditions and reaction to fire performance requirements. It is not within the scope of this Technical Specification to describe measures that ensure the preservation of the vehicles in the event of a fire.

CEN/TS 45545 specifies: measures on railway vehicles for fire protection; verification of these measures. CEN/TS 45545 specifies prevention measures. The measures and requirements specified in CEN/TS 45545 are intended to protect passengers and staff in railway vehicles in the event of a fire on board. This protection of passenger and staff is essentially based on the ability of the rolling stock to allow for evacuation in safety, satisfying conditions (according to the objectives in Clause 4) in the frame of a guided transportation system which includes in particular vehicles, infrastructure and operation rules. The present Technical Specification describes the measures to be taken in the design of the vehicles in the context of the infrastructure within which they operate. It is not within the scope of CEN/TS 45545 to describe measures that ensure the preservation of the vehicles in the event of a fire. This Technical Specification is valid for railway vehicles as defined in 3.1. Freight transportation vehicles are not covered by CEN/TS 45545. This part of CEN/TS 45545 covers: principal definitions; operation categories; design categories; fire safety objectives; general requirements for fire protection measures and their evaluation of conformity.

This part specifies requirements for flammable liquids and liquefied petroleum gas installations, e.g. for traction, auxiliary power units, heating or cooking, to cover the objectives defined in CEN/TS 45545-1. This part is not applicable to technical liquids themselves, e.g. hydraulic liquid, transformer oil, except where guidance is given as to dealing with spillages, leakage and spray generation. The measures and requirements specified in this Technical Specification 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 Technical Specification to describe measures for flammable gases, other than liquefied petroleum gases. It is not within the scope of this Technical Specification to describe measures that ensure the preservation of the vehicles in the event of a fire.

This Part 5 specifies the fire safety requirements for electrical equipment on railway vehicles, including that of trolley buses, track guided buses and magnetic levitation vehicles. The measures and requirements, specified in this Technical Specification meet the objective of protecting passengers and staff in railway vehicles in the event of a fire on board by: – minimizing the risk of starting a fire both during operation and as a result of technical defect and/or malfunction of the electrical equipment; – ensuring that electrical emergency equipment continues to be available until evacuation is complete. It is not within the scope of this Technical Specification to describe measures which ensure the preservation of the electrical equipment in the event of a fire on board.
