BS 6853 Fire test to cable - Standard

 BS 6853: Code of practice for fire precautions in the design and construction of passenger carrying trains - Table13 / Table14

 BS 6853 Fire test to cable - Brief

 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.
