EN 45545-2 The European railway standard for fire safety EN45545-2 was introduced as a mandatory requirement throughout Europe. The European safety standard aims to protect passengers and staff against onboard fire incidents in railway vehicles. The Requirement Class (R) determines what tests need to be carried out to validate fire safety for a material in use in a defined application space. The requirement defines per Design category and Operation Category what kind of HL (Hazard Level) is required. The three hazard levels are: HL1, HL2 and HL3 with HL1 being the lowest requirement and HL3 being the highest. Railway vehicles are classified in accordance with the fire hazard level associated with their design and operation.
Flame retardant PC and PC/ABS blends have been used for long time in railway applications, for its ease of processing, design freedom and optimal balance in material mechanical properties, fire safety and surface appearance. Until now, the use of those specific grades was mainly for in-colored sheet extrusion where they show excellent behavior in subsequent thermoforming, allowing to create large complex shapes ideally for interior wall/ceiling panels, window frames, partitions and seat shells.
Therefore, MCPP Netherlands has developed and introduced a complete new innovative polycarbonate based grade filament that passes the highest Hazard Level (HL3) for the most stringent requirement set R1, R6, R22 and R23.
