EN 45545-2 in brief

 

Samaro and its partners are developing solutions that meet the requirements of the EN45545-2 standard for passenger safety in rail transport.
The EN45545-2 standard is developed to facilitate the interoperability of trains across Europe, it was decided to harmonise the different train management systems including fire and smoke standards.
It replaces all the old standards from different European countries.

 

3 fire risk levels: HL1, HL2, HL3
