BS ***3 fire test to railway components－Standard

 BS***3: Code of practice for fire precautions in the design and construction of passenger carrying trains

BS ***3 Fire Test to railway components - Instroduction

The standard has been extensively revised to assist railway vehicle builders in interpreting guidance from the Safety Regulatory Authority on fire performance.It is envisaged therefore that this standard will have a wider use than the previous edition and reflects the concern of the Fire Standards Committee by upgrading the responsibilities of railway vehicle designers, builders and manufacturers, encouraging them to produce safer materials which release less toxic effluent in a fire, for future safety.

Thus adherence to the code should be considered to have provided an environment for which it has been demonstrated that:

 Acceptable control of the risk of ignition has been achieved

 Acceptable control of the rate of and total emission of heat, smoke and toxic fume has been achieved for all major usage materials and surfaces when exposed to a source of ignition

 Acceptable resistance to fire has been achieved for all materials and items required to perform as a barrier to fire or which are required to perform some function when exposed to fire

BS ***3 Fire Test to railway components – Scope

This British Standard makes recommendations in respect of fire safety for the design and construction of railway vehicles comprising or forming part of passenger carrying trains. The recommendations are applicable to new vehicles and also to substantial changes to existing vehicles

The recommendations in this British Standard cover:

a) The reaction to fire of materials;

b) The use of fire resisting barriers;

c) General aspects of design for fire safety.
