Transportation vehicles have a large passenger flow, most of the lines are in relatively confined spaces, disorderly people are highly dense, and there are many difficulties in escaping passengers and rescuing personnel in the event of a disaster. In recent years, fire accidents on trains have been frequent, resulting in serious casualties and property damage, so countries around the world are constantly putting forward higher standards of prevention for potential fire safety hazards in railways.
The design of the vehicle and the choice of materials will minimize the probability of fire, control the rate and extent of fire development and minimize the impact of fire on passengers and crews.
Therefore, it is important to assess the flammability, flame spread characteristics, heat release rate & total heat release, smoke release rate & total smoke release, and smoke toxicity of materials used on trains.
Regional standards for fire testing of rail vehicles include:
