Reliability and Safety in Rail Vehicles
The classification system defined in EN 45545-2 specifies requirements for the fire behaviour of materials and products used in rolling stock.
The thresholds for oxygen index, smoke density and toxicity are outlined in the requirement sets R22, R23 and R24.
HL3 – the most stringent of three Hazard Levels – indicates where material behaviour gives rail passengers the greatest chance of orientating themselves and not suffocating from toxic fumes in the event of fire.
To meet HL3, the oxygen index of a tested material must be above 32 percent, smoke density 300DS or lower and toxicity index of smoke below 0.75 CIT NLP.
